-------------------------------------
Multi-boot
In fact, users in China use the U8800, multi-system has been used for a long time.
So, now I will use my broken English to tell you how to use multi-system
First, you need The extra two partitions in the 4G space. you could use twosys-partition.zip to get The extra two partitions 15&16
download partition package:http://forum.xda-developers.com/attachment.php?attachmentid=787404&stc=1&d=1321675310
And
The second system-specific recovery system
http://forum.xda-developers.com/attachment.php?attachmentid=787413&stc=1&d=1321675310
put the twosys-partition.zip and you like rom's zip into Sdcard
rename the recovery_4.0.1.5_en_sys2.img to recovery2.img , then place it to /cust
Boot into recovery,flash this package directly, same as flashing a ROM.
After flashing go to advanced options, choose to reboot to recovery.
Go into recovery again, flash this package again directly, same as flashing a ROM.now you will have The extra two partition 15 and 16
OK, let's flash two system into you phone
Go into recovery again, flash you like rom's zip
boot into first system, you could use RootExplorer access /cust, rename the recovery.img to recovery1.img, rename the boot.img to boot1.img,rename the recovery2.img to recovery.img.
reboot you system into recovery, now you recovery is second system recovery,you could flash the 100911-cm7,it will auto flash into second system.
reboot system, you will into second system (CM7)
if you want change you system to first, you could use RootExplorer access /sbin/gk, you will found some .sh files,Execution the 8-ChangeSys will auto rename all
img file then auto reboot to first system.
you could copy the 8-changesys.sh to any place let you change system easy.
restore offical partition : download
Important:only the 100911-CM7 can flash into second system, other ROM only flash into first system
please backup your data, because you will lost all data in phone

wow,great! big thx geno!

great work。hope the bug be fixed soon

great~thanks for hard work~wait for a good cm7 for u8800

Wow cool. What's working/not working? Did you compile a new kernel or modify the kernel of the Vision (or something else)?

Good work , thanks for the share

Excited to see this working a lot more

waiting for the next update

please fix the bug as soon as possible

Are you the developer?

of course he is

Wow, that's amazing

good job ,THX very much

Awesome Work. It reboots every 2 minutes almost exactly. Which is probably a good thing, too much awesome at once may make my head explode. I ran ADB logcat for you if that helps:
http://pastebin.com/kZddgHpN
I'm no dev but it looks like something is wrong with the DHCP setup or rmnet0 (which i believe is related to the mobile data). I'm sure you know more. Once again, it's 2 minutes of pure awesome, then a reboot lol. Stockwell/Neopeek may know more.

Okay finally had some time today to look at this rom and I was close with the rmt_storage thing.. the 2 minute rebooting thing is because the huawei rpc service (system/bin/oem_rpc_svc) isn't being started during boot (this calls rmt_storage periodically so that's what threw me off). If you manually call it after booting then it won't reboot.
I'm not sure yet why the rpc service won't start during boot though.. might need to look at the boot logs a bit more.

Hi. I'm getting an error installing.
any ideas?
I've tried renaming the .zip to update.zip but I get the same problem.
edit: Ok, fixed it by using genokolars recovery

oh,there are so many bugs,so i want't to update

it's necessery!!!!!!!!

[ROM] Acer AV041 1.31.00 WW GEN1 w/ Root and Busybox [May 18, 2012]

Rom (Ice Cream Sandwich):
A Near stock image, modified for a clean root, busybox install
ezAcer_AV041_A500_1.31.00_WW_GEN1_RootBusybox_S.zip
(MD5: 7e9fe5642b6e082fb4382288337d8dfa)​
The long overdue update to my previous Honeycomb rom
==~== Requirements ==~==
This rom requires the unlocked ICS bootloader, I also recommend my A500 Public Recovery, however all recoverys patched for the new bootloader ought to allow installation of the rom.
Bootloader install instructions are: here thanks to civato. Note for step 4 simply ensure my update zip above is either in on the device instead of the ones listed. Note instructions below before actually flashing the rom.
Additional information can be found at Skrilax_CZ's bootloader development thread here
And my A500 Public Recovery development thread here
==~== Installing ==~==
Once you have the new bootloader and ICS recovery installed (again preferably the A500 Public Recovery but any ought to work)
Cleaning your tablet:
If you are attempting to upgrade the tablet without wiping (and there is no need to wipe if you are currently running my acer7.014.14 rooted image
Select "cleanup tab" in the main menu of the A500 Public Recovery
(If you are using another recovery, select the options for a. Wipe Cache, b. Wipe Dalvik Cache, and c. Fix Permissions)
Install the rom:
Select "install zip from sdcard" and navigate to ezAcer_AV041_A500_1.31.00_WW_GEN1_RootBusybox_S.zip
Thats it
==~== Root ==~==
Applications are granted Superuser access from ChainsDD's Superuser.apk as usual (a request asking you will appear when an application requests root, and permissions granted before the upgrade may still be active post upgrade)
adb shell: ADB by default will not have root access here you have the following options:
> if you run 'adb root' all adb operations will have root until reboot (aka 'adb shell' and 'adb remount')
> If you have a non-root 'adb shell' you can switch to root with the 'su' command
> If you wish to restore the permanent adb root on boot add the following line to the build.prop 'service.adb.root=1' this will force the old behavior of root always via adb without using the 'adb root' command.
This change has been made as its a little more secure, (However obviously still lets anyone with access to the USB port access to all the tablets data)
==~== Features ==~==
This rom is intended for users that wish a nearly stock system configuration, however either need root and busybox, or enjoy conducting more advanced tasks at the command line and wish a smooth root experience.
In addition some other small mini-fixes have been applied to the image in hope of a smooth experience.
Here is a list of the features and changes in the rom
Modified ADB to allow adb root to operate without changing the production build properties
Kernel patched to allow system remount
Busybox built from CM9 source tree and integrated into the rom
runparts (ie /system/etc/init.d functionality)
GPS lto fix thanks to waydownsouth
FDUpdater (ie system update) removed to not be prompt for an update you can't install.. if you want it the original app is in the system folder of the update.zip, (FDUpdater.apk) its not odexed so install normally)
Kernel modules md4.ko sha512_generic.ko and cifs.ko added to the rom (md4/sha512 is loaded on boot via an init.d script, users of cifs need to check the "Load cifs module" option in CifsManager.
Added Superuser
DHCP Infinite Lease bugfix (why has google not fixed this) applied as a patch to the framework.odex
Rom is still odexed (and I re-odexed the one changed odex for the DHCP patch)
Developers wanting more details or the source to anything I changed can see this detailed modification guide: http://pastebin.com/ApUjMDJ7
Note to anyone wishing to make a modification to the rom they are flashing, everything in the system folder of the update.zip is unchanged from the original rom. (when flashed the system is patched and augmented via various files and tools in the custom directory, also the boot image is pre-patched)
==~== Extras and Addons ==~==
** Overclocked test kernel: See my ezT20 kernel here (previously OCTestV3 here
(kernel last updated June 18th 2012)
** Disk IO enhancement: significantly increase diskio scores, and make the table slightly more responsive when reading/writing to flash: On this post
(diskIO last updated June 5th 2012)
==~== Tips and Tricks ==~==
This section is where I try to explain how to get the most of your tablet, and solutions to common complaints due to changes between versions.
-----) Rom "Bloat" (------
First half of what people call rom bloat is not quite true, (there is such a thing, and problems related to it)
Our tablets have 590MB system partition, a 97MB vendor partition, a 1GB cache partition, and the rest of your tablets space in a data partition (mine is 27GB, but if you have a smaller tablet model it will be less) All roms will have currently the same split between the partitions.
Its only that last partition that contains your data, the system/vendor partitions are by default read only, and the cache partition is temporary data.
System apps are on the two read only partitions, thus removing them for the most part will not cause more data to be available to your apps. Also this is storage space so having more "free" will not speed up your device (well as long as we are not too close to full.. and this rom is not)
Most of these apps play nice, they don't run unless you select them thus you can ignore they are on your tablet and all will be just as fast as if they were never installed
There is however one *Problem* Applications pre-installed that run constantly in the background that you the user are not interested in.
Solution: Freezing apps
* Goto Settings-> Apps-> All
* For any of the following that you do not use:
> Photo Browser 3D
> SocialJogger
> Acer Media
Select the app,
Choose Disable
Clear Data
If you use the app, obviously keep it enabled, also you can return to this screen and re-enable the app.
-----) Screen flickering/brightness oddities (------
I have had some brightness issues initially, simple fix was to go into settings->display->brightness uncheck auto bightness, lower the meter, and re-check auto brightness
-----) Sluggish system (------
Make sure on first boot you give the system some time (2h/3h after upgrading or re-installing where there is a large collection of media on the tablet) before measuring speed, as the system may be still sorting/indexing tablet data and will speed up when done.
Also while apps are installing the system may behave slower (if you have many market updates happening in the background)
Otherwise check running processes in settings to see if anything may be slowing down your tablet in the background (Settings -> Apps -> Running)​

Overclocked kernel [May 23rd 2012]
(wow I think we can hear crickets in here..)
Anyway using the now released source code from acer, and richardtrip's OC patches from HC I now have an overclocked kernel.
As of V3 I also have the voltage controls patched up from richardtrip's kernel.
[size=+2]AcerOCTestV3_S.zip[/size]
MD5: 6907e7585fedf534261cc8ebe23d824a
Instructions are simple: flash from recovery
Links to the github source and other information on the AcerOCTest kernels is in this related notecard
While I've only tested it on this rom, the installer is using koush's anykernel logic (or one of my own flavors of that logic anyway) and thus this ought to cleanly install on any rom based on the stock ICS kernel regardless of the tweaks the rom creator may have added.)
Also I've not had much time to test so let me know if there are issues
----
List of all versions:
V3 - AcerOCTestV3_S.zip (md5: 6907e7585fedf534261cc8ebe23d824a) May 23rd 2012
V2 - AcerOCTestV2_S.zip (md5: da01a90dda3916ec55ebb62bbb1164f1) May 22rd 2012
V1 - no public binary (caused reboots on tablet sleep)
Just tried the OC kernel on Civato's latest rom and it does work. Can't go over 1.2ghz without a reboot, but that extra bit of speed is nice.

what dosn't work? >1.2ghz or flashing it on Civato's rom
the rom ought to work, it extracts the current boot.img, swaps the zImage (leaves the ramdisk) and swaps the modules in /system/lib/modules.
as for the speed.. your device is intended for 1.0ghz any thing extra is a bonus.. the kernel thus boots at 1.0
edit: although I'll look into it some may be a new verification in the updated kernel. the tegra2 OC logic is much more complicated than the msm logic I'm used to on the HTC dream.. I'm more worried about reboot-on-wake bugs I had in earlier revisions

looking closer its a but..
So now I have two OC tests I've made.. the first one I didn't publish because while it could go > 1.2 it crashed when you put the tab to sleep. (at least when USB wasn't connected)
This one crashes when you go over 1.2.
maybe if a combine them I can get something that works...
Perhaps a slight voltage bump is needed to get beyond 1.2? In either case, 1.2ghz feels leaps and bounds faster than 1ghz using this rom. I'm starting to feel like we don't even need cyanogenmod 9 for the a500.

No.. well maybe but you not getting that far.. its a kernel BUG condition, meaning some code found some invalid input and refused to process it, instead triggered a reboot.. looking at the diff of mycode and the code in the CM thread.. no logic is different so i'll need to poke min/max rail voltages. (still sorting out all the voltages and CPU speeds.. the dream had it all in one large table .. here it seems spread out in various places between two files..)
(I'll also try to include the voltage manipulation patches just making sure things are stable first thus 1.2ghz is a better testing speed for me than trying to Max my device)
As for CM..it seems to have many interesting features.. but at some point I'm not sure its direction matches my interests.. (maybe its just become too much of a kitchen sink i don't know, that or too much now in aosp) I'm sure to look at it but probably start an aosp build with cherrypicked features I like.. until then this tweaked ics rom will need to do.
Fyi I haven't had a single issue on your kernel.
Been waiting on this! Thanks ezterry.

Well next version will have voltage controls and working higher overclock speeds
(just ironing out some minor issues with the voltage control)
Some side info and feedback I get from some users that are on ICS bootloader and still getting SoD
I made a boot.img with in the "boot.img-ramdisk" / postboot.sh = I deleted the following line
"echo 7> /sys/module/wakelock/parameters/debug_mask" and it solves the SoD problem some still have when they are on ICS bootloader.
Just had a other pm today confirming it worked.
And I'm testing your modules and OC zImage with this modded in the boot.img-ramdisk (and my other tweaks) and I don't get any SoD , screen off , back on no problem.
Also confirming 1200 is max , over that it will reboot.
Ezterry,
Thanks!
very nice kernel, I flashed the 'civato' version to avoid SOD ...
Works nicely in 1.2 Ghz...
Btw, the old "No-Frills CPU control" apk doesn't apply the upper 1.2 Ghz frequency at Boot as asked.
Do you know another tool working to apply OC at boot?
(I'm using Civato's last version of flexreaper ROM)

.. I think this solution has nothing to do with the debug variable and everything to do with *forcing* the user to install a ICS kernel and stop messing around with the HC kernel they had earlier. (since you are installing a new boot.img)
So says the code anyway. If you want to prove it wrong after the crash + quick reboot get your users to dump the last_kmsg and output of dmesg so we can actually debug what is going on.. well unless its just the wrong kernel
But if the "obecalp" works to get some your users to install the right thing and so they fix there own problem.. so be it.
--
I have to inform users of my rom its no longer my rom if they install one of your (or anyone else's) full boot images and not to complain of any resulting bugs here.. If anyone with this rom has a SoD (none reported yet.. but I block installation on the old HC bootloader) let us know if you have such an issue. (just want to add if the full boot image was modified from the one in this rom, and intended for users of this rom that isn't an issue.. the issue is when its for another rom)
Its a bit different when you flash my update on another rom, since I only swap the kernel and leave the ramdisk as is, (by unpacking and repacking the boot.img) the rom designers changes stay intact.. well unless they had a kernel module that I've not included.. but even then we will need to re-build that module)
and you can test this after boot enter terminal and run echo '3> /sys/module/wakelock/parameters/debug_mask' that is the default.
(If it is disabled it just won't print the list of wakelocks to the kernel log on suspend..)

Hopefully fixed the max speed bug, and added in the voltage controls.
Not much else yet has changed. but seems stable.
Its the same anykernel package as last time so it should cleanly swap the kernel (leaving the previous ram disk) for any ICS stock kernel based rom.
(Is there one app out there that actually knows how to successfully set *both* cores frequency and set voltage on boot, without giving the world access to the /sys files [so a malicious app cant overclock+fry the device or under clock it so it feels painfully slow]... soon I'll just write an init.d script for myself to echo the values directly into the kernel settings /rant)
I use setcpu.

I don't like that he (and has always) granted global write permissions to the /sys/ files controlling the CPU/Voltage settings .. and it was acting flaky on voltage settings on boot.
Voltage Control looked good until a verification in /sys indicated if left the second CPU core at 1GHz
Now poking system tuner/system tuner pro.. many interesting features. Not sure they quite understand use root to write the value.. or set the file to your own ownership..
*ANYWAY*
you can check these yourself manually at the command line/adb shell:
CPU0: /sys/devices/system/cpu/cpu0/cpufreq
CPU1: /sys/devices/system/cpu/cpu1/cpufreq
current status of the voltages is in the readonly: frequency_voltage_table
list readonly of available frequencies is: scaling_available_frequencies
list readonly of available governors: scaling_available_governors
the current min frequency: scaling_min_freq
the current max frequenct: scaling_max_freq
the current cpu governor: scaling_governor
the current undervolt levels (negative values are over volting): UV_mV_table
UV_mV_table is in the same order as frequency_voltage_table, and if written to with the same number of values will update the voltage levels.
I got a question , why :
sha512_generic.ko = what does this do ?
modules.order = why does it need to know the order ?

Introduction
It's finally here :-D CM10.2 (Android4.3.x) for the Bell Canada Samsung Galaxy S2 HD LTE (SGH-I757M). Among the most notable new features are new adreno graphics drivers with triple buffering (this is project butter). More desired may be the new privacy manager features that allow you to control, on a per app basis, which information you wish to share. Other improvements include an improved lockscreen cLock and a new integrated Superuser.

What Doesn't Work
* I experienced an incompatibility with some of my existing mp4 media files and when gallery tries to load them they cause a soft reboot. Loading these videos into the gallery media player using a 3rd party file manager seems to work without issue, it is the loading of the preview in gallery that causes the phone to crash.
Solution: The solution is to use a file manager to move the mp4 files to a new directory and add a ".nomedia" file to that directory so that when browsing photos in the gallery, it does not try to load the offending mp4 files.
* When unlocking the screen, sometimes only the capacitative buttons light up, and the screen doesn't come on. This seems to happen about 80% of the time.
Solution: This can be fixed by locking the screen, then unlocking it again. In about 5% of these cases the screen does not come on again. Just repeat the steps again until it does.
This has been fixed as of build 20131029
* You may notice a screen flicker when you first flash this ROM. This is due to a bug where the system can't decide whether to render the graphics with the cpu or the gpu, thus the flicker.
Solution: This is fixed by turning on Settings -> Developer Options -> Disable HW Overlays (You must first enable Developer Options by pressing 7 times on Settings -> About Phone -> Build Number). This will be reset on every boot. if you install Universal Init.d, my 91fixoverlays script will run on each boot and fix this automatically.
This has been fixed as of build 20131029

FAQ
Q. How do I install SuperSu?
A. Install the latest version from the market, and also make sure you have Universal Init.d installed and active. Then open SuperSU and when it asks you to update the superuser binary, answer yes and make sure you select the "TWRP/CWM" method. This will reboot your phone into receovery where the superuser binary will be updated and the su daemon script added. When your phone reboots, recovery will warn you that your device may possibly be unrooted. This is because of the install-recovery.sh script that is required to start the superuser daemon which allows SuperSu to manage superuser permissions. You are not unrooted ;-)
If your having difficulties getting SuperSu installed, try downloading the flashable zip and manually flashing it to your phone.
UPDATE-SuperSU-v1.65.zip
* Thanks to @formercontra for this tip *
* Make sure this is the way in which you want to manage superuser permissions as I have not yet found a way to revert to the integrated superuser without having to re-flash the rom
Q. How do I access Developer Options?
A. Go to Settings -> About Phone and scroll to the bottom. Press the Build number 7 times to activate the Developer Options.
Q. Why is my screen flickering?
A. There is a bug in this ROM where the board can't decide whether to display the frames with the cpu or the gpu, thus the flickering while it resolves the issue. To fix it, disable HW Overlays in Developer Options. This needs to be set on every boot unless you are running Universal Init.d and my 91fixoverlays script is present in the /system/etc/init.d folder.
Q. When I unlock my screen, my menu/home/back/search buttons come on but the screen is black?
A. This is a known bug in this ROM and is on the list of things that need to be fixed. For now, when this happens, just lock the screen, then unlock it again and the display should come back. If it does not, repeat until it does (the most number of times i had to do that was 3).
Q. I was browsing my pictures/videos in the gallery and my phone rebooted?
A. This seems to be caused by the gallery trying to generate a preview from the first frame of an mp4 created on older versions. Simply move the mp4's to a different directory with a file manager and add a ".nomedia" file to the folder to stop the gallery from trying to scan them. To open them, open with a filemanager and then select the gallery media player and it will play without issue.

Use the Bell Flex APN. You can select it by going to:
Settings -> Wireless & Networks -> More -> Mobile Networks -> Access Point Names
This helps fix some issues with VPN and some other system services.
Logcat what is it and how do I get one?
A logcat is the system log of events that occur on your device. This log provides the developers with some useful information pertaining to crashes and other bugs you may encounter while using the ROM and/or apps running on the ROM. Getting a logcat is generally a very simple thing. Just open your terminal emulator on your phone and type the following commands without typing the $ as it denotes a command on the command line:
$ su
$ logcat -v long > /sdcard/logcat.txt
Click to expand...
Click to collapse
The first command above will ask you to grant superuser permission to the terminal emulator which you must accept. The second command will create a file at the root of your sdcard called logcat.txt and then start writing the logs to this file. Since the logcat is a continuous function, your terminal emulator will not return you to the command prompt after the second command as it will continue to write logs until you stop it by pressing the x to close the emulator.
If you are experiencing an issue with an app, then you need to do the steps above to get the logcat recording, then press your home button so that you don't close the emulator, but put it in the background. Then you do the action that causes the bug to occur and then open the emulator and terminate it to stop the log from writing. this ensures that the error is located somewhere around the end of the log and makes it easier for us to spot
What is dalvik-cache and why do I need it?
To explain dalvik cache, you must understand how an app is pieced together. An apk (android app) is like a zip file and contains a bunch of files inside. Two important files to note are the resources.arsc and the classes.dex files. They are compiled versions of the resources (images, sounds, xml files) and classes (source code files) of the app. When android boots into a ROM for the first time, and everytime you install an app, the system performs an optimization called dex optimization which means that is pulls the dex file out of the app and places it into what is called your dalvik cache. The system can then pre-load these dex files and allow the app to start quickly.
Dalvik cache is stored in two locations, at /data/dalvik-cache for user apps and at /cache/dalvik-cache for system apps. We unfortunately have a very small partition for /cache, only 100MB and this sometimes causes a side effect on first boot where it fills up to much with apps that only ever run on the first boot to setup the system and then other dex files cannot be written to the /cache partition which causes them to Force Close (FC). The trick in this situation, is to bear through the FC messages to get the system to the home screen, then reboot into recovery and Wipe Dalvik Cache from the Advanced sub-menu. This will delete all the dex files in both locations I mentioned above and will force the system to regenerate them upon reboot, and this time, those 1-time running apps don't start up and don't end up being optimized which allows the necessary dex files to be created for the apps that were FC'ing.
I have moved what I could from the system partition to the data partition to spare some extra space on /cache but this still sometimes happens, especially as the ROM's get slightly bigger every new major version.

Wow, you already found it and I wasn't even finished putting everything up... make sure you use the new CWM, very very very important!
Followed the instructions ( to the best of my ability ) but I'm getting a random red border flicker every so often. I'm also not seeing the 91fixoverlays script in my init.d folder.
Smooth rom so far!

I totally forgot to update the build.prop with the build type, it is responsible for the red border. Either use a build.prop editor or open the /system/build.prop with a text editor and change the following line:
ro.build.type=eng
Click to expand...
Click to collapse
Change it to:
ro.build.type=user
Click to expand...
Click to collapse
You will need to reboot after making this change.
In regards to the 91fixoverlays script, I do appologize. I forgot to include it in the zip... Please download the attached 91fixoverlays.txt file and rename it to 91fixoverlays and move it to /system/etc/init.d and change it's permissions to match the other files in that directory.
Sorry for missing these two things. I will update the packages ASAP and will post a note when it's done so you know that there is no need to follow the steps in this post.
Much appreciated! No more red flickering. Thanks!
Wow! Thank you!

I'm first!! (to post, anyway).
Installed the ROM. Did a clean flash (factory reset).
Upon the boot I got "Unfortunately Bluetooth Share has stopped" but appears to be no ramifications.
ROM looks great! Feels smooth.
Will do more testing.

I think this is due to our oddly small cache partition. Only 100MB as compared to the skyrocket at 300MB. Currently, I only moved four apps in the gapps package to the data partition do that their dex files don't end up in the /cache/dalvik-cache dir and instead end up in /data/dalvik-cache. I think I need to move others. I also think that it happens only on first boot without side effects because a couple of the installed apps only run on first boot, then their dex files can be deleted (I think this happens automatically).

Rotation is not working for me, though I always keep it on portrait anyway so I am not complaining.
Rotation doesn't work here, and every so often I run into spells where the only button that works is the home button and haptic feedback stops working all around. A reboot fixes it and it seems random. Other than those few things this is soooooo smooth. I'm happy. Thanks so much!

Hey guys, to fix the sensors, download this attachment sensors.default.so.txt and rename it to sensors.default.so, move it to /system/lib/hw and give it the same permissions as the other files in that directory, then reboot and your sensors should be working
Works now! Thanks ya muchly.

Code:
[COLOR="red"][B][SIZE="4"]*** Disclamer ***[/SIZE][/B]
THIS ROM IS FOR THE CANADIAN SGH-I757M ONLY... DO NOT FLASH IT ON ANOTHER DEVICE!
By flashing this ROM, you are voiding your phones warranty (Unless you return it
to complete stock which is possible, but beyond the scope of this thread). You
also agree that I will in no way be held responsible in the event that your
device becomes bricked (Not likely to happen). In addition, you are responsible
to take the necessary backups of your apps, data, sms, contacts, calendar events, etc.
If you agree, then please continue on ;)[/COLOR]
Code:
[COLOR="red"][B][SIZE="4"]*** NEW RECOVERY REQUIRED ***[/SIZE][/B]
Due to the addition of user control in CM10.1/CM10.2/CM11.0, you are required to update
your recovery to a supported recovery with a version greater than 6.0.39. As of this writing, the latest available
version is Philz Touch Recovery 6.57.9 (based on CWM 6.0.51) for the SGH-I757M. There is currently not a
version of regular CWM for this device that will flash Kit Kat ROMs.
If you flash the new ROM with the old incompatible recovery, you risk loosing
your sdcard under a bunch of subfolders.[/COLOR]
Code:
[COLOR="red"][B][SIZE="4"]*** NEW RADIO FIRMWARE REQUIRED ***[/SIZE][/B]
As of CM10.1, ICS radios (I757MUGLH2) are no longer supported. You must download the new JB radios (I757MUGMC5).[/COLOR]
Introduction
It's finally here :-D CM11.0 (Android4.4.x) for the Bell Canada Samsung Galaxy S2 HD LTE (SGH-I757M). There is a lot to be said about Kit Kat with it's clean white icons and new launcher. The focus with Kit Kat was to make the device use less RAM and imrove performance, and so far it's running great.

Changelog
Code:
[B]November 22, 2014 - Build 20141122[/B]
* Increased kernel version to Titanium 1.1.1
* Added cpu input boost framework - credit: sultanxda
* Added cpu OC (The scale goes up to 1890MHz, but you should only put it as high as 1836MHz since I was getting random reboots with 1890MHz. 1674MHz is the default OC and 1512MHz is the default CM OC) - credit: TeamFahQ/sultanxda/titanic-fanatic
* Added low power flash mode which will use a low powered flash when the battery is equal to or below 35%. This should help with the camera causing the phone to shut down when trying to take pictures using the flash. This threshold may need to be tweaked, so please let me know if you still experience shut downs related to using the camera. - credit: sultanxda
* Added sgs2hdbell as a device name to the updater-script to allow all bell i757m devices to flash the ROM without the need to edit the updater-script.
* Added panel undervolt interface. - credit: sultanxda
* More memory optimizations. Some of the extra RAM that the previous optimization gave us has been allocated to other things such as the surface flinger. Available RAM is now around ~760MB.
* Removed vbus_present wakelock for good (it worked it's way back in somehow)
* Added fast charge. Phone will now charge at 1200mA until 95% regardless of your charging source (AC/USB)
* Added exFAT driver to kernel. It's a filesystem like ext4 but is based on Windows FAT filesystem. You can format your sdcard as exFAT as it's supposed to be faster than vFAT which is what our sdcards are formatted as. Make sure you backup your sdcard contents before formatting it as exFAT and keep the backup until your sure you want to stick with exFAT.
* Removed NFC since I don't think anyone uses it and can't figure out how to have it disabled by default so it is removed completely. If someone is using NFC, let me know and I'll add it back but for now, I just see it as a battery drain.
[B]September 10, 2014 - Build 20140910[/B]
* Kernel now has a custom version number in addition to my kernel name of Titanium
* Optimized kernel memory mapping to increase our physical RAM from ~730MB to ~800MB (a whole 70 extra MB... whoa!)- credit: sultanxda
* Removed mDNIe (it's not supported/working)
* Removed 91fixoverlays script (no longer needed)
* Removed persist.hwc.mdpcomp.enabled from build.prop (hack to fix the hwoverlays because fb drivers are broken somehow) - credit: sultanxda
* Added GPU overclock from 266MHz to 320MHz (helps a lot with the UI lag) - credit: sultanxda
* Added code for 2 phase OnDemand governor - credit: sultanxda

FAQ
Q. How do I install SuperSu?
A. Install the latest version from the market. Then open SuperSU and when it asks you to update the superuser binary, answer yes and make sure you select the "TWRP/CWM" method. This will reboot your phone into receovery where the superuser binary will be updated and the su daemon script added. Reboot your phone and you should be rooted.
If your having difficulties getting SuperSu installed, try downloading the flashable zip and manually flashing it to your phone.
UPDATE-SuperSU-v1.65.zip
* Thanks to @formercontra for this tip *
* Make sure this is the way in which you want to manage superuser permissions as I have not yet found a way to revert to the integrated superuser without having to re-flash the rom
Q. How do I access Developer Options?
A. Go to Settings -> About Phone and scroll to the bottom. Press the Build number 7 times to activate the Developer Options.
Q. I was browsing my pictures/videos in the gallery and my phone rebooted?
A. This seems to be caused by the gallery trying to generate a preview from the first frame of an mp4 created on older versions. Simply move the mp4's to a different directory with a file manager and add a ".nomedia" file to the folder to stop the gallery from trying to scan them. To open them, open with a filemanager and then select the gallery media player and it will play without issue.

Here are my settings for the color/gamma controls!
Color:
Red -> 60%
Green -> 45%
Blue -> 45%
Gamma:
Red -> 0
Green -> -5
Blue -> 5
Why does the color/gamma controls get set to a value other than what I've set?
This is something I have not yet resolved, but I have noticed that it seems to jump up by 5. So if you want 50% for example, try setting it to 45%.
Logcat what is it and how do I get one?
A logcat is the system log of events that occur on your device. This log provides the developers with some useful information pertaining to crashes and other bugs you may encounter while using the ROM and/or apps running on the ROM. Getting a logcat is generally a very simple thing. Just open your terminal emulator on your phone and type the following commands without typing the $ as it denotes a command on the command line:
$ su
$ logcat -v long > /sdcard/logcat.txt
Click to expand...
Click to collapse
The first command above will ask you to grant superuser permission to the terminal emulator which you must accept. The second command will create a file at the root of your sdcard called logcat.txt and then start writing the logs to this file. Since the logcat is a continuous function, your terminal emulator will not return you to the command prompt after the second command as it will continue to write logs until you stop it by pressing the x to close the emulator.
If you are experiencing an issue with an app, then you need to do the steps above to get the logcat recording, then press your home button so that you don't close the emulator, but put it in the background. Then you do the action that causes the bug to occur and then open the emulator and terminate it to stop the log from writing. this ensures that the error is located somewhere around the end of the log and makes it easier for us to spot
How do I take a dmesg (kernel log)?
It's fairly simple, open up your terminal then type the following:
$ su
$ dmesg > /storage/sdcard0/dmesg.txt
Click to expand...
Click to collapse
This will save the log to the root of your sdcard as dmesg.txt. Just post that or send it to [email protected] if it's to large to post here
What is dalvik-cache and why do I need it?
To explain dalvik cache, you must understand how an app is pieced together. An apk (android app) is like a zip file and contains a bunch of files inside. Two important files to note are the resources.arsc and the classes.dex files. They are compiled versions of the resources (images, sounds, xml files) and classes (source code files) of the app. When android boots into a ROM for the first time, and everytime you install an app, the system performs an optimization called dex optimization which means that is pulls the dex file out of the app and places it into what is called your dalvik cache. The system can then pre-load these dex files and allow the app to start quickly.
Dalvik cache is stored in two locations, at /data/dalvik-cache for user apps and at /cache/dalvik-cache for system apps. We unfortunately have a very small partition for /cache, only 100MB and this sometimes causes a side effect on first boot where it fills up to much with apps that only ever run on the first boot to setup the system and then other dex files cannot be written to the /cache partition which causes them to Force Close (FC). The trick in this situation, is to bear through the FC messages to get the system to the home screen, then reboot into recovery and Wipe Dalvik Cache from the Advanced sub-menu. This will delete all the dex files in both locations I mentioned above and will force the system to regenerate them upon reboot, and this time, those 1-time running apps don't start up and don't end up being optimized which allows the necessary dex files to be created for the apps that were FC'ing.
I have moved what I could from the system partition to the data partition to spare some extra space on /cache but this still sometimes happens, especially as the ROM's get slightly bigger every new major version.
Flashing Recovery for the First Time
Flashing CWM for the First Time
This is a pretty simple step once you get past the install recovery script which I'll explain how to accomplish. Make sure you follow the instructions closely because Odin, the program the we use to bypass the security, can do some serious damage to your phone if your not careful.
1) Download the latest CWM tar.md5 to your computer from my androidfilehost.com repo here:
http://www.androidfilehost.com/user/?w=settings-dev-files&flid=12461
2) Download Odin 1.8.5 zip and extract all the files to a folder on your computer (i use my desktop):
http://www.androidfilehost.com/?fid=23501681358544719
3) The drivers are very touchy on windows computers, so I recommend that you install Samsung Kies which will ensure that the drivers are installed and setup correctly. You can download kies from here:
http://www.samsung.com/ca/support/usefulsoftware/KIES/JSP
4) Be careful now that you have kies installed, it does not play nicely with Odin, so whenever you use Odin, you should ensure that kies is completely closed and not open in the system tray by opening your Task Manager and "End Task" to any kies process such as "Kies.exe" and "KiesTrayAgent.exe"
5) Now, with kies closed, open Odin and do not change any settings. It should look like this:
6) Now click on the Bootloader button and search for the CWM tar.md5 you downloaded from my androidfilehost.
7) Now turn off your phone, and when it's powered off, press and hold the volume down and power buttons at the same time until you see the warning message about Download mode. Press volume up to enter download mode.
8) With Kies closed on your computer and Odin open cwm tar.md5 loaded into the bootloader section and your phone in Download mode, plug your phone into the computer with your micro usb cord and wait for odin to display a "Device Added" message which tells you that odin sees your phone.
9) This is the tricky part and is all based on timing, so pay close attention.
10) You will now press the "Start" button in odin and wait for it to complete. It will display a green "Pass" message in the first box when it's done. At this time, the phone will reboot and will start with a slight vibration to notify you that it's booting up. It's exactly at the time that the phone vibrates that you need to immediately remove the micro usb cord and press and hold the volume up and volume down buttons simultaneously until cwm loads. If you miss this mark, android will boot, the install_recovery.sh script will run and overwrite the cwm you just flashed with the old stock 3e recovery (arghhh) and you will have to go through this process again.
If CWM complains about the install_recovery script, let it fix/remove it.
Once you have CWM flashed, you can use it to backup/restore your system, flash custom ROMs and you can even flash our CWM upgrades through CWM itself.
First Wood Woot !! And many thankyous.
Update-
This Rom is flawless so far. I have no issues that existed for me in CM10.2JB . Status Bar doesn't freeze. Apps aren't killed mid use. Calender sync was fixed by installing Google calendar from play store and then removing it. (I use Cal app). There's almost no lag in multi tasking. I'm very happy.?? kit Kat!

Crossbreeder won't install (it did on the earlier 4.4 builds).. but Adaway works just fine and everything's working smoothly. Love the music in the lockscreen! also noticed there's even more governor parameters to tweak, which is always a good thing

That's due to the new recovery. If your on a Windows system, download 7zip if you don't have it already.
Here's what you do, open this roms zip file and extract only the update-binary from META-INF/com/google/android to a location on your computer. Then you can close the ROM zip. Now open the crossbreeder zip with 7zip and browse to META-INF/com/google/android and simply drag the extracted update-binary into the crossbreeder zip file replacing it's update-binary with the one from cm-11. Then close the zip and upload to your phone and flash away

Did you wipe and factory reset? Did you use the wipe to install new rom option?
This ROM must be flashed clean. No dirty flashing unless you already had cm-11 flashed.

I am curious, in your 10.2 thread you said the calendar could not be assigned a gmail account in cm 11.
Was this resolved? For me it's a deal breaker (loving your cm10.2 anyways).
If it hasn't been fixed could we add it to the OP in the what doesn't work section?

Philz touch cwm was just updated and now uses a new exfat module for mounting the sdcards. It's supposed to be faster than the fuse alternative. This version also fixes the resolution of the background image, the software buttons and the vibration.

The calendar works in slim. I think the calendar sync adapter is missing in cm-11. Can I get someone to add this apk to your /system/app dir give it the same permissions as the others, then reboot and try connecting the calendar to your Google account. I'm out of the house right now so can't test it myself.

** DoPa5 (AOSP - Kitkat) ** is now available - see this post for details and downloads
Click to expand...
Click to collapse
DoPa v2.7 is a ROM for Sero 7 Pro owners everywhere. Whether bought in the US, Britain, Australia, Germany, or elsewhere, your tablet is supported.
The ROM starts with well-tested AOSP code and adds core functions where needed but skips the frills that are easy to add on - and remove when they cause problems. It's aimed at people who want to choose their own features and not have them imposed by the developer.
New / Improved
International Support - a single ROM for all Sero 7 Pros sold worldwide
New in v2.7 - support for the German model of the Sero 7 Pro (m470bsg)
Speed Control - a unified kernel provides speed when you need it and stock performance when you don't.
Use the new Performance page in the Settings app to control it
exFAT - support has been moved into the kernel for improved performance
Boot Animation - a handsome new DoPa animation thanks to @mikembley, our first-ever UK user
To get you started customizing your ROM, v2.7 offers these add-ons:
built-in: SuperSU, Xposed Installer GravityBox, Phab7
optional: have your tablet claim it's a Nexus7 to get more apps in PlayStore
The package does not include any Google apps (e.g. Playstore). See this thread for links to the latest GApps packages.
Installation
UK / AU / DE / First-time Users
If you're upgrading from a stock ROM (any variety), please click the "show content" button and read the instructions very carefully - they're long but your tablet's continued good health may depend on it!
STEP 1: Install Philz Touch Recovery
Users outside the US must use this version of Philz to install the ROM - neither the stock recovery nor other versions of CWM or Philz will work. Users in the US should use it just to avoid problems.
Stock Recovery
If you still have the stock recovery program you'll have to use the 'fastboot' program to install Philz. On Windows, this requires installation of the 'ADB' USB drivers while in fastboot mode (see below). A package containing the drivers, fastboot, adb and other files can be found in the 2nd posting on the DoPa Stock ROM thread. Note: there are several batch files (*.bat) in the package - do NOT run them.
put fastboot.exe in a convenient directory, then unzip sero7pro-philz6.58.0-dopa-v2.7.zip and put the file philz.img in the same directory (you won't need the other files)
unplug any USB cable, then press and hold Power+VolumeUp; the word "fastboot" should appear on the screen (nothing further will appear)
plug the USB cable from your PC into the tablet, then install the driver (open Device Manager, right click on "Other Devices->Fastboot", then select "Update Driver Software")
after installing the driver, open a command prompt ("DOS window") and change to the directory containing the files
enter fastboot flash recovery philz.img
when done, force the tablet off, remove the USB cable, then reboot into recovery: Power+VolumeDown - you should see the word "recovery", then the Philz menu
CWM
If you have CWM installed, copy sero7pro-philz6.58.0-dopa-v2.7.zip to an SD card, insert it in the tablet, then:
remove any USB cable, then boot into recovery: Power+VolumeDown
select "Install Zip", then "Choose zip from /storage/sdcard1"
select the file, then OK the selection
when done, back out to the main menu, select "Advanced options", then "Reboot recovery"
after the initial "recovery" screen, you should see the Philz menu
Regardless of how you install Philz, the result should be the same. If it boots OK, compatibility is assured
STEP 2: Backup
I can't emphasize this enough: you must make a backup of your existing ROM. If something goes wrong, there's no way to get your device working again other than to restore it using the backup you've made. There's also another reason to do a backup: before installing the new ROM, you will have to reformat your /data partition. This will wipe out your apps, your settings, and most importantly, all the music/photos/etc stored on your "internal SDcard". These last items can be restored if you follow the instructions below:
ROM
You must do your backup onto a real SD card that you can remove because your "internal SDcard" will be erased in the next step. In fact, it wouldn't be a bad idea to do two backups (preferably to different cards) just in case one is faulty.
on Philz main menu, select "Backup and Restore"
next, select "Backup to /storage/sdcard1" (the 6th item on that menu)
if there's enough space on the card, the backup will start without any further prompt; it could take anywhere from 3 to 15+ minutes depending on the amount of data and the speed of your card
if needed, you can enable compression to create a smaller backup: select "Misc Nandroid Settings -> Default Backup Format -> tar + gzip", then on the previous menu, tap on "Compression" to set the appropriate level
Internal SD card
This is optional but worthwhile if you have files you value stored on the tablet:
on Philz main menu, select "Backup and Restore"
next, select "Custom Backup to /storage/sdcard1" (the 9th item on that menu)
on the next screen, deselect everything, then select "Backup /data/media" (the next-to-last item)
finally, select "Start Custom Backup Job"
STEP 3: Install the DoPa ROM
Before you begin, you may want to download a Google Apps ("Gapps") package that you can install after the ROM. See this thread for a selection of packages. To avoid complications, I'd suggest choosing the "Nano Modular Package" to get just the basics - you can always upgrade later. Put your Gapps package along with the ROM zip on an SD card and insert it into the tablet - you can use the same card you're using for your backups.
on Philz main menu, select "Wipe and Format Options", then "Custom Format Options"
select "format /data and /data/media (/sdcard)" (the 8th item), then OK your choice
back on the main menu, select "Install Zip -> Choose zip from /storage/sdcard1"
select sero7pro-aosp444-dopa-v2.7.zip, then OK your choice - the install process should take about 40 seconds
next, install your Gapps package
return to the main menu, select "Reboot System Now", then hold your breath for the next 3-4 minutes
the Hisense screen should be up for less than a minute, followed by the DoPa boot animation for another 2-3 minutes
when the Google setup screen appears, you'll probably get a warning that "Bluetooth Sharing" has stopped - after you clear it, you'll never see it again
If the boot animation is still running after 5+ minutes, force the tablet off, then reboot. If that doesn't fix it, try formatting /data again. If it still doesn't work, restore your tablet from your backup ("Backup and Restore -> Restore from /storage/sdcard1"), then post a message here. If everything works out as hoped for, re-read the first posting in this thread for details on some of the features (and problems) of this ROM.
Upgrades
While any SELinux-enabled version of CWM or TWRP can be used to install the ROM, the companion Philz Touch CWM-based recovery is highly recommended if you use exFAT-formatted SD cards.
from DoPa AOSP Kitkat ROMs (v1.0-v2.6) - no need to wipe or format anything!
from pre-Kitkat (v4.4.x) or any CM-based ROMs - wipe your /data partition before installing to avoid unnecessary problems.
install sero7pro-aosp444-dopa-v2.7.zip
- the installer will wipe (but NOT format) /cache and dalvik-cache for you
install your preferred Gapps package
- upgraders: this is required to prevent your downloaded Google apps from crashing
optionally, install the Nexus7 spoof (sero7pro-nexus7spoof-dopa-v2.7.zip)
reboot (ignore any "fix root" prompt - it's incorrect)
f2fs / ext4 Migration
This DoPa ROM gives you the flexibility to format any of your built-in partitions using either the f2fs or ext4 file systems.
As part of your install - or at any time - you can switch formats without losing any data. Click "show content" for instructions.
If you haven't already installed Philz Touch Recovery, please do so first. Philz has gotten complicated, so read this carefully!
make a nandroid backup to your external SD card
select Wipe and Format Options, then Custom Format Options
select toggle f2fs <-> ext4 migration
- be sure there's a confirmation message at the bottom of the screen
select each partition you want to convert or wipe, then select the format and OK your choice
Important: to convert your /data partition, you must select format /data and /data/media (/sdcard)!!!
use Custom Restore from /storage/sdcard1 to restore the contents of the partitions you reformatted
Notes
Speed Control - this version uses a redesigned kernel that caps processor speeds at stock levels during start-up, then adjusts them once the tablet is up and running. Go to Settings->Performance to enable this feature, and to set the top speeds for the CPU (1.0-1.5ghz) and GPU (448-520mhz). When disabled,the processor will remain at stock speeds (1.2ghz/448mhz) unless changed by a 3rd-party app.
Encryption - the first time you formatted your /data partition, you lost the ability to encrypt your tablet's data. Using the companion Philz Touch Recovery to reformat /data (using either filesystem) will restore that ability. To preserve your existing data, do a backup first, then restore just /data when done. Note: you must select "format /data and /data/media (/sdcard)" when reformatting.
OTG Charging Support - this kernel supports charging the tablet while an external device (flash drive, keyboard, etc.) is attached to the USB port. This feature requires either an OTG 'Y' cable or an OTG USB hub, and the AC adapter that came with the tablet. For this to work, power must be connected to the cable or hub before plugging it into your tablet. The OTG device(s) can be attached/detached at any time.
WiFi Display (a.k.a. Miracast) - video works but its performance may depend upon your TV; audio does not work.
Bluetooth Sharing - on the initial boot, this service will FC due to a timing issue. The system will restart it and you should never see this error again.
Added/Changed in v2.6
International Support - added support to the kernel for the British and Australian models of the Sero 7 Pro
Overclocking - replaced separate standard and overclocked kernels with a unified kernel that uses less power when overclocked; added a new Performance page to the Settings app to control it
exFAT Support - moved exFAT support to the kernel for improved performance
Boot Animation - added a custom boot animation created by @mikembley
Added/Changed in v2.51
Flexible Formatting - added F2FS support for the /thirdparty and /mnt/modem partitions
Bug Fix - enabled Philz Touch Recovery to format the /thirdparty and /mnt/modem partitions using EXT4
Added/Changed in v2.5
Flexible Formatting - enabled use of either F2FS or EXT4 for any of the built-in partitions
External Storage - added support for F2FS, and for devices formatted without a partition table (i.e. Windows-style "super-floppies")
Android version - upgraded from AOSP 4.4.4_r2 to AOSP 4.4.4_r2.0.1
Recovery - added a DoPa version of Philz Touch Recovery
Added/Changed in v2.1
SD Cards - added support for SD cards formatted with the NTFS or exFAT filesystems
Android version - upgraded from AOSP 4.4.4_r1 to AOSP 4.4.4_r2
Added/Changed in v2.0

Thanks man been running it since day one no problems and very stable.
Can We call these the Semi OFFICIAL ROM ?
I installed v1 after it booted up play store wasn't installed. Did any one else experience this? I did a dirty flash and a full wipe.

How much free space should there be on a system after a fresh install?

I followed the instructions and noticed the same thing and gmail kept crashing. Flashing the latest gapps will fix all of that. I still have some testing to do and will report back later.

GPS and Google music
I noticed on version 0 that GPS could take awhile to lock on, and if you turned it off and back on that sometimes it wouldn't lock on at all. I also noticed an issue when running Google music where it would freeze and cause the tablet to reboot. Anyone having these issues on the new build? Otherwise, this is one of the cleanest KitKat builds I've used

Don't use Google music but I do use scanner radio and whenever I switched streams the tablet would freeze and I would have to hold the power button to turn the tablet off.
Now its working like it should. So this latest build might fix Google music.
Another issue I was having is when I opened the calendar it would not close hitting the back button. Its closes fine now.
The GPS doesn't seem to load any slower for me than it did with the stock ROM but I don't use it much.
Anyway I would recommend trying this latest build. Just make sure you wipe cache and dalvik cache and flash the latest gapps. Everything should still be the same as before when you boot with the new ROM and hopefully you will notice some improvements.

Just want to thank you for fixing the sound bug. V4A is working perfectly and as far as I can tell so is everything else. I will keep testing and if I run across anything strange I will post here. Your work on this is very much appreciated

This is a plain-vanilla build of KitKat for those who prefer their enhancements added on rather than built in. The only changes to the AOSP and kernel code are those needed to ensure compatibility or to enable standard features Hisense omitted (e.g. USB-OTG support). Because it relies on well-tested AOSP code, it is likely the most stable KitKat ROM available for this tablet. For the same reasons, it is almost certainly not the fastest KitKat ROM either.
To make it more functional, the package includes a handful of apps most people find useful: SuperSU, ES File Explorer, Xposed Installer, GravityBox, and my Phab7 UI switcher. To avoid the wrath of Google, it does not include any GApps; see this thread for links to the latest packages.
Installation
Having an SELinux-enabled version of CWM or TWRP installed is a prerequisite. You can find versions built by randomblame here or by davepmer here.
If you're upgrading from v0 of this ROM, clearing cache and dalvik-cache should suffice. Otherwise, do a full wipe of both your data and cache partitions. As always, a backup of your existing setup is recommended.
Notes
All features should be present and work as expected with these exceptions:
WiFi Display (a.k.a. Miracast) - video is enabled but very slow; audio is disabled because it doesn't work and generates 45 error messages per second when enabled
SELinux - the kernel runs in permissive mode due to missing entries in its configuration.
As these issues are resolved, the ROM will be updated accordingly.

Thanks for the rom. After flashing the rom I rebooted, powered down and installed gapps. On reboot I got a message about root access possibly being lost and offering to fix it, I said yes. First time I get that, is it ok? (It seems to be working ok)

As noted in the OP, none of the GApps (e.g. Playstore) were included in this ROM. I have updated its verbiage to be even more explicit. As to GMail crashing, I'm a little puzzled how that could happen if it wasn't included - did you mean the generic Email app?

I hope not: v1 wouldn't have been released if that bug were still present. The problems you encountered were caused by enabling sound effects, either built-in or 3rd-party - the notes for v0 said as much. Perhaps Google Music enabled them automatically.

I ran into that too - and something even odder. SuperSU's su and daemonsu program files should have a flag that marks them as authorized to give root access. That flag is now missing but I can still get root whenever needed. I don't know if this is to be expected with SELinux in place or just something specific to SuperSU. I'll investigate...

After installing the ROM, the "Gapps Standard" package, and Antutu, Settings->Storage says I have 5.48gb available. This is the free space on your /data partition and includes the space used by your emulated SD Card (which is actually just a subdirectory of /data).
"Smart ass alert"
Not only was playstore not installed, it doesn't give me the winning lottery numbers for next week! What gives?
Ok, being serious, Thank you for your time and effort. This weekend I am going to finally give this a try.
Dolorespark,
I haven't messed with any sound effect settings, so it must be Google Music messing with things. Have you noticed any issues with GPS? I can run any of the other rom's, including CM11, and it locks on immediately, but it seems random with AOSP. Sometimes I'll wait a coupled of minutes and it'll get a lock, and other times it won't lock on at all. Anyway, thanks for all you do. I'll keep testing, and keep my trusty backup of DOPA v2.
Working brilliantly so far. V0 to V1 smooth after adding gapps back to the mix. Sounds like time to reinstall V4A and sync some commute podcasts!
Thanks Dolorespark!

I had this issue on v0 as well and it seems that it's not gone yet. I only wiped dalvik & cache coming from v0 so I'm not sure if that's part of the problem, but I'm still experiencing the Google Play Music crash. It only seems to crash when playing content that hasn't already been cached locally. Attached is a logcat.

No it was gmail. It would close followed by the message "unfortunately this application has closed" or something like that. It wasn't really crashing but rather would not stay open. Anyway flashing the latest gapps fixed that and all is good for me so far.
I played with the tablet extensively last night and did not experience any problems. Even movies, streaming or local using XBMC play using a bluetooth headset. There is no stuttering as there was in all of the previous Jelly Bean roms, stock....DoPa1 and DoPa2. I don't know if that was a KitKat fix or what but I am very happy with the stability of this rom and the fact the XBMC bluetooth bug was fixed is icing on the cake. Of course V4A makes it even better.
I will continue to run the rom and will post if I find any bugs. Thanks again.:good:
Been running since v1 was posted. Have to say the music bug is no more! Listening to lucky mixes all day today and email, g+, and everything my wife and kids have done on it. No problems! Thanks You have really taken your time to make this rom perfect!!!!

Did you use the latest GApps package? As Gazoo119 noted, that fixed a problem with another app that uses Google Play Services. If the problem persists, you may want to go to Apps->Google Play Services, then tap the "Manage space" button. On the next screen it lets you clear all data.

I hadn't tried GPS at all until you mentioned it. I installed Google Maps but couldn't get a lock at all. It's raining here, so I couldn't get fully in the clear. Instead I sat in my car and it still did nothing. Finally, I forced-stopped the app, cleared data and cache, then retried. This time it only took a few seconds to find me. I then turned off GPS, rebooted, and moved to my semi-covered patio. After getting everything going again, it took 10-15 seconds to get a rough fix (off about 70 feet) and it continued to hold it even after I went inside. You may want to try clearing Maps' data (if that's what you're using) to see if that helps.

Whatever crash you're seeing isn't the one that I fixed. That one was produced a full-blown hardware crash with a register dump. Your logcat doesn't show a register dump or even a Java runtime exception dump. There were two errors that caught my eye but I don't know if either would cause an "Unfortunately..." popup.
Code:

Here, the (software) communication link being used to download "Le onde" was broken. Later on, you got this error:

This download failure is a lot easier to understand: your WiFi connection had dropped. I don't know that either of these is something I can fix. As above, you may want to try the obvious fixes if you haven't done so already: use the most recent GApps package, clear the app's cache and data, and play with the app's caching options.

[ROM] Sero 7 Pro (US/UK/AU/DE) - AOSP 5.1.1_r14 DoPa5 v1.3

** DoPa6 (AOSP - Marshmallow) ** is now available - see this post for details and downloads
Click to expand...
Click to collapse
DoPa5 v1.3 is a Lollipop ROM for Sero 7 Pro owners worldwide. It focuses on core functionality that must be built-in and relies on 3rd-party apps to provide features that can be added-on. This release also offers a version of TWRP Recovery that is compatible with all models of the S7P.
Key Features
International Support - a single ROM for all Sero 7 Pros sold worldwide (US, UK, Australia, Germany, and elsewhere)
Speed Control - speed when you need it and stock performance when you don't
OTG Charging - charge the tablet while an external device is attached to the USB port
Flexible Formatting - full support for both F2FS and EXT4 on your internal storage, and exFAT/FAT32/NTFS/F2FS/EXT4 support for external storage
Installation
First-time Users
If you're upgrading from a stock ROM (any variety), please click the "show content" button and read the instructions very carefully - they're long but your tablet's continued good health may depend on it!
STEP 1: Install TWRP or Philz Touch Recovery
Users outside the US must use the DoPa versions of these recoveries to install the ROM - neither the stock recovery nor other versions of CWM or Philz will work. Users in the US should use them just to avoid problems.
Stock Recovery
If you still have the stock recovery program you'll have to use the 'fastboot' program to install TWRP or Philz. On Windows, this requires installation of the 'ADB' USB drivers while in fastboot mode (see below). A package containing the drivers, fastboot, adb and other files can be found in the 2nd posting on the DoPa Stock ROM thread. Note: there are several batch files (*.bat) in the package - do NOT run them.
put fastboot.exe in a convenient directory, then unzip the recovery zip and put the .img file (twrp.img or philz.img) in the same directory (you won't need the other files)
unplug any USB cable, then press and hold Power+VolumeUp; the word "fastboot" should appear on the screen (nothing further will appear)
plug the USB cable from your PC into the tablet, then install the driver (open Device Manager, right click on "Other Devices->Fastboot", then select "Update Driver Software")
after installing the driver, open a command prompt ("DOS window") and change to the directory containing the files
enter, as appropriate, fastboot flash recovery twrp.img or fastboot flash recovery philz.img
when done, force the tablet off, remove the USB cable, then reboot into recovery: Power+VolumeDown - you should see the word "recovery", then either the TWRP or Philz menu
CWM
If you have CWM installed, copy your choice of recovery zip to an SD card, insert it in the tablet, then:
remove any USB cable, then boot into recovery: Power+VolumeDown
select "Install Zip", then "Choose zip from /storage/sdcard1"
select the file, then OK the selection
when done, back out to the main menu, select "Advanced options", then "Reboot recovery"
after the initial "recovery" screen, you should see the TWRP or Philz menu
Regardless of how you install your chosen recovery, the result should be the same. If it boots OK, compatibility is assured
STEP 2: Backup
I can't emphasize this enough: you must make a backup of your existing ROM. If something goes wrong, there's no way to get your device working again other than to restore it using the backup you've made. There's also another reason to do a backup: before installing the new ROM, you will have to reformat your /data partition. This will wipe out your apps, your settings, and most importantly, all the music/photos/etc stored on your "internal SDcard". These last items can be restored if you follow the instructions below:
You must do your backup onto a real SD card that you can remove because your "internal SDcard" will be erased in the next step. In fact, it wouldn't be a bad idea to do two backups (preferably to different cards) just in case one is faulty.
using Philz, select "Backup and Restore", then "Backup to /storage/sdcard1" -if there's enough space on the card, the backup will start without any further prompt;
using TWRP, select "Backup", then tap "Storage" (halfway down the screen) and ensure that "sdcard" is selected; on the previous screen, swipe the slider to start the backup;
it could take anywhere from 3 to 15+ minutes depending on the amount of data and the speed of your card
if needed, you can enable compression to create a smaller backup: for TWRP, you can check "Enable compression" on its main backup screen; for Philz, select "Misc Nandroid Settings -> Default Backup Format -> tar + gzip", then on the previous menu, tap on "Compression" to set the appropriate level
STEP 3: Install the DoPa5 ROM
Before you begin, you may want to download a Google Apps ("Gapps") package that you can install after the ROM. See the TK Gapps thread for details. I recommend the "Nano Modular" package which gives you the basics - you can always upgrade later. Put your Gapps package along with the ROM zip on an SD card and insert it into the tablet - you can use the same card you're using for your backups.
using TWRP, select "Wipe", then "Format data"; on the next screen type "yes" to confirm you want to proceed;
using Philz, select "Wipe and Format Options", then "Custom Format Options"; next select "format /data and /data/media (/sdcard)" (the 8th item), then OK your choice;
return to the main menu
using TWRP, select "Install"; at the top it should show "Storage: sdcard" - if not, tap there and change the setting
using Philz, select "Install Zip -> Choose zip from /storage/sdcard1"
select sero7pro-aosp511-dopa5-v1.3.zip, then OK your choice - the install process should take about 40-60 seconds
next, install your Gapps package
return to the main menu, select "Reboot" then "System" if using TWRP, or "Reboot System Now" for Philz, then hold your breath for the next 3-4 minutes
the Hisense screen should be up for 30 seconds, followed by the DoPa boot animation for another 3 minutes
If the boot animation is still running after 5+ minutes, force the tablet off, then reboot. If that doesn't fix it, try formatting /data again. If it still doesn't work, restore your tablet from your backup ("Backup and Restore -> Restore from /storage/sdcard1"), then post a message here. If everything works out as hoped for, re-read the first posting in this thread for details on some of the features (and problems) of this ROM.
Upgrades
UK, AU, and DE users must use the DoPa versions of TWRP or Philz Touch to install the ROM because they are the only ones compatible with your tablet. US users can use any SELinux-enabled version of CWM, Philz, or TWRP.
from DoPa5 AOSP Lollipop ROMs - no need to wipe or format anything!
from DoPa AOSP Kitkat ROMs (v1.0-v2.7) - a clean install is recommended but not required
from pre-Kitkat (v4.4.x) or any CM-based ROMs - wipe your /data partition before installing to avoid unnecessary problems.
install sero7pro-aosp511-dopa5-v1.3.zip
- the installer will wipe (but NOT format) /cache and dalvik-cache for you
install your preferred Gapps package
- upgraders: this is required to prevent your downloaded Google apps from crashing
optionally, install the Nexus7 spoof (sero7pro-nexus7spoof-dopa5-v1.3.zip)
reboot (ignore any "fix root" prompt - it's incorrect)
f2fs / ext4 Migration
This DoPa ROM gives you the flexibility to format any of your built-in partitions using either the f2fs or ext4 file systems.
As part of your install - or at any time - you can switch formats without losing any data. Click "show content" for instructions.
If you haven't already installed TWRP or Philz Touch Recovery, please do so first.
TWRP
make a backup to your external SD card
select Wipe then Advanced Wipe
select the partition to reformat, then tap Repair or Change File System
on the next screen, tap Change File System, then F2FS (or EXT4 to restore the default file system)
swipe the slider below to start formatting
when done, use the Restore option on the main screen to restore the contents of the partitions you reformatted
Philz
make a nandroid backup to your external SD card
select Wipe and Format Options, then Custom Format Options
select toggle f2fs <-> ext4 migration
- be sure there's a confirmation message at the bottom of the screen
select each partition you want to convert or wipe, then select the format and OK your choice
Important: to convert your /data partition, you must select format /data and /data/media (/sdcard)!!!
use Custom Restore from /storage/sdcard1 to restore the contents of the partitions you reformatted
Changes since DoPa5 v1.2
Xposed and GravityBox - these staples of the DoPa KitKat ROMs are back and preinstalled to provide all the tweaks you want - and none of the ones you don't
ArchiDroid Optimizations - this version of Android was built using gcc 4.9 and is highly optimized thanks to settings provided by JustArchi. To help ensure stability, the kernel uses standard optimization levels but is better tuned to our Cortex A9 processor due to the use of linaro 4.9 (a version of gcc optimized for ARM processors).
No Odex-ing - odex-ing has been abandoned because Xposed recompiles all apps, making the .odex files redundant. There should now be enough space on the /system partition to install the TK-Gapps Micro package.
Adaptive Brightness - a longstanding bug that could cause the screen to go black has been fixed. Overall brightness levels have been adjusted to provide greater dynamic range in low lighting conditions.
Notes
Xposed - having the Xposed framework installed shouldn't cause any issues, but if you wish to remove it you can do so using the xposed-uninstaller available in the Xposed XDA thread. The Xposed Installer and GravityBox apps will remain but will be inactive - you can use a root-enabled filemanager to remove them if you wish.
Encryption - if you wish to encrypt your /data partition, you must first use Philz Recovery to format it. Using TWRP to format may cause the partition to become un-decrytable, resulting in the complete loss of all your data. This is NOT an issue if you don't plan to use encryption.
WiFi Display - end a WiFi Display session from your television, not the tablet; doing so from the tablet may cause it to lock up. Chromecast is reportedly not subject to this issue.
USB Audio - booting up with a USB audio device attached may result in a bootloop.
Gapps - due to limited space on the /system partition, the TK Gapps's "Mini Modular" and larger packages will not install. I suggest using the "Nano" package, then downloading those apps you really want from PlayStore.

Thx for all your hard work
on these tablet
Thx
ok, so I have a question or several as I remember them...
I noticed in Beta 4 that we were (or at least I was) suffering from the well documented play movies bug that was afflicting a number of 2013 Nexus 7 models.
Has this been fixed yet?
If not, is there a workaround?
If so, what is it?
I also noticed some performance and stability issues when using the performance tab along with apps like 3c Toolbox and System Tuner. Unfortunately, I did not see a way to use performance tab to overclock the gpu and leave the cpu clock stock so that I could tweak the system through the aforementioned apps.
Also, can the cpu be overclocked beyond 1.5 Ghz?
If so, is this already enabled, or is there some magic involved?
I really liked the beta 4 (beta r3) Rom and the way it looked, felt, and ran.
I found it to be better at managing free memory than kitkat in that I had at least 50% more free ram than Kitkat. I believe this contributed to some of the performance increase. But I had a hard time with the Google Play Movies bug. And some people were saying it was a general problem within the os's video subsystem.
Legend, keep up the great work
Excellent work! Looking forward to this!

I'm sorry I didn't know about this until you mentioned it. I'm too poor/cheap to buy stuff from Google Play Movies, so I'd never have learned about this on my own. Fortunately this was my day off, so I was able to spend the afternoon chasing down this bug. Here's the fix - install it from Recovery:
sero7pro-video-drm-fix-dopa5-v1.0.zip
I'll repackage the main ROM in the near future to include this fix, but first I want to investigate a few possible problems I noticed while getting this fixed.

Every time you display the Performance page, it will restore all parameters to the values you set previously. If 'Speed Control' is enabled, it will reset the CPU & GPU speeds, overriding values set by some other app. Your best bet is to turn it off. If neither of the apps you mention knows how to set the GPU speed, you can do so temporarily from a terminal or permanently from an init.d script like so:
Code:
echo -n 1250 > /sys/kernel/tegra_cap/core_cap_level # "1200" is 448mhz - "1250" is 520mhz

Also, can the cpu be overclocked beyond 1.5 Ghz?

Nope, not without extending the kernel's DVFS table further, then recompiling. Someone had it running at 1700mhz, but I'd consider that ..umm.. ill-advised for a chip that's intended to run at 1200-1300mhz.
Loving the first build. Very silky smooth speed and pretty stable as well as far as Lollipop is concerned at this point. As far as themes are concerned I haven't had too many issues using them on the current CM12 nightly for the Sero 7 Pro despite the DPI difference. Can't wait to see where this goes from here. Thanks for all the hard work! :highfive:

Well, on nVidia's page it recommend a maximum of 1.6 GHz, so 1.7 is not too much of an overboard if Hisense had built these units well enough. However, even with 1.5 GHz the chips is already running uncomfortably hot so it would be wise to back off from any higher clock. I do however think that the GPU of this tablet is a lacking a bit of oomph (ironically), is it possible to raise the clocks of the GPU beyond 520MHz? (granted that there would be a possibility of artifacts )

I'm sorry I didn't know about this until you mentioned it. I'm too poor/cheap to buy stuff from Google Play Movies, so I'd never have learned about this on my own. Fortunately this was my day off, so I was able to spend the afternoon chasing down this bug.

Being under that magic number of 10 posts, I couldn't post this in that main thread, and when I tried to post in the q&a thread where "reply" sent me, the forums bot catcher tripped me up.
Thanks, that worked like a charm.
Every time you display the Performance page, it will restore all parameters to the values you set previously. If 'Speed Control' is enabled, it will reset the CPU & GPU speeds, overriding values set by some other app. Your best bet is to turn it off.

I did, and had stability. Just didn't know about just gpu o/c.
If neither of the apps you mention knows how to set the GPU speed, you can do so temporarily from a terminal or permanently from an init.d script like so:
Code:
echo -n 1250 > /sys/kernel/tegra_cap/core_cap_level # "1200" is 448mhz - "1250" is 520mhz
echo -n 1 > /sys/kernel/tegra_cap/core_cap_state

To my knowledge, they don't, or at least I haven't figured that part out yet. Haven't figured it out in trickster mod either. I'll try the code. I only remember seeing one init.d file, does it matter where in that file I add the code?

The Tegra3 is a family of SoCs with models designed for mobile, automotive, and embedded use. Ours is the low-power mobile version. Some variants do have higher maximum clock speeds but they use more power at every frequency step than ours.

Possibly. The original overclock patch just upped the GPU speed to 520mhz without increasing the voltage any - and that seemed to work. When I rewrote the o/c code, I increased the voltage when running at 520mhz for what I considered solid reasons, Since it now has more power, I suspect I could up the speed somewhat without causing problems. However, even at a higher speed, it's still going to be an also-ran in today's market.

Having some other app set the CPU or GPU speeds isn't going to make it any more or less stable than having the built-in facility do it.
Be aware that if you're trying to use one of these apps to set the Interactive Governor's parameters, you're wasting your time. Not only does our Interactive Governor NOT work like you'd think - and not work like other implementations - it's totally ineffective. Every time the kernel brings another core online, it kicks all cores to the maximum allowed speed, totally sabotaging the governor's efforts. If you use Trickster to track the time at each speed, you'll see that the bulk of the time is spent either at very low speed or max speed, with all the intermediate speeds hardly used at all.

Create a new file named, f'rinstance. "02gpuspeed". Put "#!/system/bin/sh" on the first line, then the code I provided on the following lines. The files will be executed in alpha-numeric order: 00banner, 02gpuspeed, 99SuperSUDaemon. Be sure to set its permissions to '755' so it is executable.
I pretty well figured that would be the case, but...
Based on my somewhat limited understanding ,If you have a utility in the Rom trying to manage the cpu speeds, and an app trying to do the same with me "choosing" to use the performance governor, conflicts are bound tio arise. Based on my pc understanding, conflict equals poor performance and instability.
And it was honestly one where I was using performance settings for the gpu, and then one of the other apps for the cpu.
So, I found that if I simply turned off the performance settings and lived with the lower gpu clock, my system ran stable. So I was asking about how to get the higher gpu clock without using the cpu overclock portion of the performance tab.
You pretty well answered that, and I thank you.
Now, do I need to include the bit in the code at the end of the first line where it says 1200 is 448, and 1250 is 520?
Also, I don't understand setting permissions to 755. I understand setting read, write, own, etc, but not 755, if that's the case, then what app do I use for that? I created the file as a blank text document on my tablet directly and input the code there, then rebooted. Or did I screw the pooch on that one?
Sadly, I know nothing about the individual governor settings within each governor configuration. Therefore, I figure that the wisest and safest course of action is to leave it alone. It's easier and safer to work with the stuff I DO know until I can get feedback and advice from someone who DOES know.
I realize that some of this may seem stupid to you, but it's the only way I know to learn.
I will make another post later when I have more time to comment on some other things I keep seeing and would like to know what to do there.

The CPU/GPU settings on the Performance page are set-and-forget values. They simply set the maximum speeds once bootup is done, and again when you display that page. They don't monitor anything - the CPU governor does that, and it is constrained by these settings. The corresponding settings in the other apps you've tried operate the same way.
You should be aware that the "performance" governor is really no governor at all. It simply sets the processor to the maximum permitted speed and never changes it. On the whole, this governor generates more heat than performance.
I found that if I simply turned off the performance settings and lived with the lower gpu clock, my system ran stable.

This strongly suggests that your device really can't handle the higher speed - at least when the CPU is running full-bore at all times. You may want to search for the postings in some of the early S7P threads where people described attaching copper foil to the SoC to dissipate excess heat.

Anything after a '#' in a shell script is a comment. As to '755', that's "read/write/execute" for the owner, and "read/execute" for the group and other users. Do a search for the 'chmod' command for more details on setting and interpreting Unix permissions.
Ok, that's fair enough.
Occasionally, I'll boot and get an error that the process called system is not responding and then it wants to know if I want to wait, or close it. It will do this every subsequent boot until I wipe cache and Dalvik (because I end up doing both out of habit) from recovery and then all is well again for several boot cycles where we start up again.
What am I missing here?
Are we free to discuss RRO theming for the S7P in this thread for now? I have been following BitSyko Development for a week or so and opted into the Layers beta and so on. I will be spending some time this week to figure this all out.

Since I'm not familiar with RRO theming how is this different from the themes released for say CM12 and the like?

Of course you're welcome to discuss RRO - especially since it gives me an opening to throw in my 2 cents
Runtime Resource Overlays provides a way to override and/or replace the "resources" (icons, layouts, colors, strings, and fixed values) that are built into an .apk file. Since the resources used by Android itself are packaged into an .apk, you can modify the OS as well as individual applications.
RRO has been around for a long time but no one other than Sony ever used it. BitSyko's greatest contribution has been to make people aware that it's a superior way to do theming which is already built into the OS and is fairly easy to use. Unlike CM's theme engine, no custom code is required.
Beyond that, their contribution is somewhat less revolutionary than their many admirers seem to think. Their efforts are directed primarily at ease of use. The Layers app is essentially a file manager that makes copying themes into place a bit easier. What the app does you can do yourself using ESFileExplorer or ADB (though without some niceties they've added).
Their tweaks to the OS are designed to make life a bit easier for themers by changing hard-coded color values into "symbolic references". In other words, rather than specifying the color for each checkbox, you say each one should be the "checkbox_color", then define what that means somewhere else. That way, rather than having to modify the color of many different checkboxes, you change the definition of "checkbox_color" once and they all become that color.
Now, as to what all this means to the Sero 7 Pro and the DoPa5 v1.0 ROM... I delayed the ROM's release for several days until I could get their patches in place and tested, so this facility is in there and ready for use. The problem is that none of the themes I've seen really support the S7P. Any color changes a theme makes will show up just fine (I'm using someone's orange theme currently). However, all the icons are targeted at higher resolution screens than ours, so the OS ignores them and uses the same ones it has always used. If you can find themes for the Nexus 7, or some of the older Asus or HP tablets that also have a 1280*800 screen (213dpi), they should work just fine.
FYI... if you want to install a theme without using Layers, create an 'overlay' directory in '/system/vendor' (i.e. '/system/vendor/overlay'). Next, get some theme packages from this thread and unzip them. Select the .apk files you want, copy them into the 'overlay' directory, then reboot. If you don't like the result, delete them and reboot again.
Perfect explanation @dolorespark on RRO. I'm hoping eventually some kind of dark holo blue theme is made for RRO as all I really need is the color scheme.

So you want black on holo blue aka 33b5e5? I'm going to make a white/pink themed for my daughter as its her tablet but I will see what I can do for you while I'm at it.

That would be amazing if you could. Here is an example of what I mean as well.
