Hi all, first of all I would like to know who the device maintainer is for cm... Secondly, this being a xxxhdpi device wouldn't it be better to use the custom cm/caf xxxhdpi dalvic heap and hwui heap files. Thirdly what's the go with the ever so slow boot animation that's really got my thinking maybe cm isn't really setup properly for this device yet

Compile it with the Muppet proprietary files and all works fine. CM is open source and anyone is allowed to make a build.

Well I compiled aosp from straight source using the muppets blobs, cm kernel and aosp angler device tree with a couple additions to allowed inline kernel building.. Boots fine but no radio, baseband unknown

Been compiling CM using TheMuppets for quite some time.
CM on N6P has its fair share of bugs since the first day. I'm annoyed by the fact that many of them aren't touched in 5 months of ongoing nightlies (including that slow boot as you said - some of my lower-powered devices boot much faster than my N6P), but now that a snapshot is out there, people should have already submitted reports to JIRA.
Nevertheless, I still think that 1) directly contacting the maintainer would be more effective (though at the cost of the maintainer's privacy) and 2) JIRA should allow bug reports and feature requests for nightly channel.

This is what happens when I compile pure aosp using themuppets blobs, stock kernel compiled from source, and device tree with inline kernel building enabled,, what does this mean??? I'm using the latest vendor image too.. Is it because I have used android-6.0.1_r31 branch

It's because the system partition has been modified.

Dm-verity I think is enabled for system I think, or it could be vendor I'm not sure, but I used the commits from cm for verity, would reverting them fix the problem???

I have yet to be able to compile a working aosp version for the 6p so I couldn't tell ya. I have gotten cm to work though. I just know that toast on boot is associated with the "your device is corrupt and can't be trusted" warning from DM verity failing. A custom kernel can fix it and SuperSU also can get rid of it.

I haven't gotten that message. I might get in contact with a couple of the ROM devs to see what's needs to be done

Just an opinion:
Since Nexus 6P is LTE 2CA enable device ,
any possibility got a setting enable or disable,
or " 4G+ " or " 4G" logo , now all the day showing LTE ,

[Thinktank]Bringing Jellybean to the Play -- Alpha GSM/CDMA [8/22]

Xperia Play Users,
I am currently working on bringing CM10 to the Play, and I'm looking for input from anybody else who has ideas.
The Rules:
Post something constructive, no "Good Luck" "reserved" etc. this thread is for working through problems when building CM10
That said.
Update: I'll be posting errors here, so it'll be easy to keep track of.
First error I hit (& fixed? (compiler hasn't failed yet on this one)) deals with hardware/qcom/display/libcopybit where copybit_c2d.cpp fails to compile with a couple of errors related to "KGSL_USER_MEM_TYPE_ION" is not declared. (iirc)
I fixed this (I think) by replacing CM10's qcom/display with caf's qcom/display
Second error: (Erroring out right now)
In-line kernel building. I'm getting a (possible) GCC compiler false error where it says
Code:
/home/paxchristos/Android_Source/cm10/kernel/semc/msm7x30/drivers/net/wireless/bcm4329/wl_iw.c: In function 'wl_iw_set_pmksa':
/home/paxchristos/Android_Source/cm10/kernel/semc/msm7x30/drivers/net/wireless/bcm4329/wl_iw.c:5335:5: error: array subscript is above array bounds [-Werror=array-bounds]
/home/paxchristos/Android_Source/cm10/kernel/semc/msm7x30/drivers/net/wireless/bcm4329/wl_iw.c:5338:5: error: array subscript is above array bounds [-Werror=array-bounds]
/home/paxchristos/Android_Source/cm10/kernel/semc/msm7x30/drivers/net/wireless/bcm4329/wl_iw.c: At top level:
cc1: error: unrecognized command line option "-Wno-unitialised" [-Werror]
Possible fix: for now turn off in-line kernel building until either error is solved.
Error 3 -- Removed in-line kernel building, but forgot to set device/semc/zeusc/prebuilt/kernel to copy to out/target/product/zeusc/kernel ... whoops
Error 4 -- The way things are sent to logcat has been changed from ICS
Code:
/home/paxchristos/Android_Source/cm10/prebuilts/gcc/linux-x86/arm/arm-linux-androideabi-4.6/bin/../lib/gcc/arm-linux-androideabi/4.6.x-google/../../../../arm-linux-androideabi/bin/ld: out/target/product/zeusc/obj/SHARED_LIBRARIES/lights.semc_intermediates/lights.o: in function write_string:device/semc/msm7x30-common/liblights/lights.c:87: error: undefined reference to 'LOGE'

Fixed by copying over liblights/ from jellybean version of msm7x30-common/
Error 5 -- Same error happens with msm7x30-common/libsensors/
Fixed the same way as error 4
Error 6 -- Last error I'm gonna talk about tonight:
I did (apparently) a half baked revert to using a prebuilt kernel & it just bit me in the butt. I'll fix it tomorrow & keep updating this.
Fixed it by using half of FXP's custombootimg.mk where it calls (PRODUCT_OUT)/kernel instead of (TARGET_PREBUILT_KERNEL)
Anybody else up for learning with me & briniging JB to the Play?
Pax
UPDATE: Pre-alpha release are available here: http://www.mediafire.com/?6ggud46a7c6cq
Latest kernel is here: http://forum.xda-developers.com/showpost.php?p=29498363&postcount=233
Remember, this is an alpha, a lot of stuff does not work. Please logcat any errors you find, otherwise (unless it's something like baseband unknown) I WILL IGNORE THEM
What Works:
CDMA Data
Calls
SMS
AUDIO!!
HW Video
GPS
What Doesn't Work:

Thank you, I think for JB CM wants to use -O2 when compiling so I'm not gonna touch that one (for now)
A Good place to start would be with Keiran's building ICS tutorial with some changes.
First off, I'm using Ubuntu 10.04 LTS, but Ubuntu 12.04 LTS *should* work (no guarantees)
To download the vendor tree (vendor/semc)
use this instead of what Keiran has (koush cleaned out a lot of the vendor trees out of his git, and mine is outdated)
Code:
git clone https://github.com/kali-/proprietary_vendor_semc.git -b ics semc
also, I'm using the ICS device tree (same as keiran) instead of JB because the JB tree's are not 100% functional right now.
Pretty much if you follow that (& I suggest instead of doing make -j# bacon do mka bacon) & run into any errors, i'll help with whatever suggestions I might have (or anybody else)
Note: If somebody needs help trying to build AOKP, I'll help, but I'm not as familiar with the source as I am with CM
Pax
Also, before I forget, here a how-to sync caf's (code aurora forums) repo (similar to cm/AOSP/etc)
https://www.codeaurora.org/xwiki/bin/QAEP/
The branch I synced was jb.

hi,
it won't boot on sony ericsson hdpi devices without msm.... changes (look at mini pro thread you will find a lot of usefull information about it)
you need to enable triple buffer in the kernel
Thanks Nickholtus, i'll look into it.
Status 6 error in the update-script (really? off the cm-10 building ?!?!) so i'm working on that now...
if you can fix the framebuffer error in the kernel we have a fully booting rom
kamarush made a build for me (from cm10 sources) with play device tree (his own)
only that error is preventing a boot
edit: can you upload your current kernel?
i know a ugly fix to get it at least booting, but i am on holiday now and i only have a windows pc with slow internet and no kernel

While I'm no help for this, for the script stuff, can't you enlist the help of the supercharger guy? He seems to be pretty adept with script lark.
Obviously, that's coming from an outsider.

If you mean Custom Roms... we can't do anything until we can pack / unpack the boot.img/or recovery.img to make a custom recovery.
jeah thats right, i was wondering because my expirience with atrix 2 , previous to the ics update, i was using supercharger rom series, but again i understand that they got a leak to work on, and a bootstrap to flash the restores they where creating, and that stock leaked rom was awesome

Would be nice to know for sure. The current methods cannot find 'Android Magic'.
I'm looking forward to seeing this forum get some custom ROMs too...
Looks like progress is getting on with it now
Any updates on custom ROM making for this device?
I've followed the README from <link to Motorola's sourceforge for razr i, deleted because I'm a new user> , got to the final step, but now I'm stumped. What make target should I choose? 'make full_x86-eng' and 'make generic_x86' have no make rules. A simple 'make' generates a framework build error.
What do I have to do in order to get a bootable image (built from source) for the Razr i?
I'd appreciate any kind of advice. Thanks in advance.
PS: Many thanks Matt, turl1 and the other developers that worked on this device.

You won't be able to build a full android system from that source. The most you can do is
Code:
$ . build/envsetup.sh
$ lunch generic_x86-eng
$ make [I]target[/I]
Where target is something like out/target/product/generic/system/bin/bluetoothd or bluetoothd
I am working on a device tree. Writing it from scratch isn't easy because there is no device I can base this on. No other x86 tree out there. And I still dont have a device. I did make threads requesting for a device but they got closed down. So once I have something built I'll make a new thread.

There's at least 10 device trees on the android-x86 project. And AOSP itself has a generic one, to build the x86 emulator platform. And I made a basic one to build recovery already, with support to generate the newer x86 boot image format.
Just saying

Generic x86 and the razr I are too far apart. Also the android x86 ones are too far apart too (I am working on a android x86 tablet). I have already written more than 450 lines of the device tree by hand, and there is a lot more to go right now. I have patched bionic for x86 builds, I need to patch the build folder next, and even busybox needs patching, etc. I am now working on making a perfect set of the 3 important files, BoardConfing.mk, device.mk and proprietary-files.txt. My android x86 tree is a total of 181 lines (which in itself is twice the size of the trees on android-x86). Its fun, but really time consuming. Also the AOSP ones are generic ones, they will work on any system if you have all the correct drivers installed or compiled via the kernel, but Razr I needs the files to be pulled from the stock build, and it needs a lot of them, including kernel drivers.

I'm playing a bit with AOSP 4.2 as I got some free time. This is what I found out so far:
bionic needed no patches. I seriously doubt it needs any on 4.1 (CM) either as recovery built fine.
build needed no patches either on both cases.
dalvik needed a 4-liner to build on AOSP (makefile fixes), I haven't tried to build it on CM
there's no busybox on AOSP, I patched the one on 4.1 already to be able to build recovery, it's all on CM Gerrit as you'd expect from a CM developer like myself
my tree is already 120 lines, as soon as you add the media decoder config and audio routing config you'll go over 180 lines
having proper drivers isn't enough, you need proper HALs too. And I haven't really looked, but I'd be surprised if you had to pull kernel drivers from the stock rom

1) bionic needs patching, patch already submitted to CM gerrit libdvm basically
2) build needs patching for the boot.img
3) dalvik has been patched
4) Odd, didn't notice that
5) Probably wont required pulling in kernel drivers, but would required pulling in the correct drivers for the defconfig
I'd be happy if you wanted to work together to get this working. PM me

re. 2, I actually did need to patch build on AOSP after all . CM on the other hand, has BOARD_CUSTOM_BOOTIMG_MK from the tf tablets.
Hey I posted a rom over at droidrzr.com for use till aosp is ready. This should be enough till we get a jb leak

Hi Folks
While I don't own a RAZR I , I have been Jaffing around with building CM10.1 and AOSP for x86, I've been getting in going on my FX8120, just need to sort the OpenGLES MESA drivers out.
Anyways I've got CM10.1 built for x86 using the mr1-staging branch ( I think it's been merged to cm10.1 ) and an edited mini-x86 device tree .
Busybox was a B**stard to build though, although on one of the branches there is an .config-minimal-x86 .config-full-x86, still needed tweaking tho.
I submitted my patches http://review.cyanogenmod.org/#/c/27377/ and http://review.cyanogenmod.org/#/c/27373/, however It seems x86 isn't top of cm's agenda.... or I'm missing something about assigning reviewers.
Obviously a base x86 build is only part of the story for you guys as you'll face all the regular problems that emedded devices have, not checked the specs for the RazR but I'm sure there's some binary blobs in your future,
Hack On Folks! :good:

[ROM][UNOFFICIAL][4.4.4][3.4 Kernel] CyanogenMod 11.0 Nightlies (tenderloin)

It's been requested that I create a new thread for this so as not to clog up @milaq's thread.
As some of you may have seen in flintman's Evervolv and milaq's CM threads, there has been a lot of work on the 3.4 kernel for tenderloin. Its a pretty awesome feat to have this running on our good ol tenderloin. =)
The gratitude for this kernel and build needs to be given to almost anyone but me. (Flemmard, flintman, jcsullins, Dorregaray and everyone that came before me on this device (dalingrin, green, and other's I'm sure that I'm missing)). I've had my tenderloin for quite awhile but never really done much with it until recently.
Anyway, without further ado, I present to you nightlies of CM-11.0 for tenderloin with a 3.4 kernel and -caf based HALs. Basically what this means is we'll be running the latest code from codeaurora on our msm8660 tenderloin.
THERE WILL BE BUGS! This thing is not perfect. It is still in active development.
CURRENT BUGZ (in no particular order):
- Bluetooth steals battery, but DOES work (jcsullins) - also sixaxis app doesn't work =(
- Camera is a bit derpy still, major wip, it takes pictures though (Dorregaray)
- Other stuff? Probably, yea
Destructions: PLEASE READ
1. This is a /data/media rom (relevant). What that means is you should be partitioned with a very small 'media' partition and a very large 'data' partition. The benefit of this is that your /sdcard and /data partitions share the big chunk of your usable space, just like any newer phone does these days. Use TPToolbox to achieve the new partition scheme: http://forum.xda-developers.com/showthread.php?t=2756314
2. You'll need a recovery that has both /data/media support and selinux support. Any of the following will work. Flashable via recovery.
-PhilZ Clockworkmod 6.0.4.7 (non-touch)(will backup and restore in both cwm and twrp format)
-Milaq's ClockworkMod 6.0.5.4
-Flintman's TWRP
3. Now you're ready to flash the rom. Downloads here: http://www.invisiblek.org/roms/cm-11.0/tenderloin/

I'd recommend wiping data when coming to this rom or going to a different one (going between milaq's and this should be fine).
These are automatically built on my personal server at home and then uploaded. There may or may not be issues during the build times so don't always expect a fresh build every day. You can follow the automated twitter account here which will spit out a tweet once the build is finished uploading.
Sources:
-Kernel
-Device Tree
-CM Sources (the rest of what's needed)
There are a couple more changes and a couple other repos that are required to build this. Add this stuff to your .repo/local_manifests/roomservice.xml in order to build this yourself (after syncing the cm source of course)
http://pastebin.com/jKAMWM8T
You'll also need to cherry pick this commit from jcsullins: http://review.cyanogenmod.org/#/c/54380
Feel free to fork and fix!
Again -
Thanks to everyone that has contributed to making this rom.
Flemmard, flintman, jcsullins, dalingrin, green, milaq, the entire CM team and I'm sure many others.
Good new year present.
Looking forward to when Bluetooth is working. That and the black boxes were the only thing keeping me off KitKat.

invisiblek, I used your 20131226 ROM. It kept crashing and rebooting every time I played a video. Netflix would crash immediately on loading and reboot the tablet. Has this been fixed with your 20131231 build?

I believe Flint said video playback was still a bit broke around that date. I remember loading that build and Diceplayer would crash upon playing a video, but it would only crash back to the home screen (not entirely crash and reboot). I think Flint said he fixed it earlier, so try 20140101 when it comes out.

Replace it so you can use the new CWM to flash this build. I believe /boot is limited to 30mb so trying to keep both may not work.
allstar319, what about the disappearing apps? Has that been fixed?

No clue. I heard of apps disappearing from the Google Home Launcher, but not getting completely removed or preventing apps from being installed. Is that the launcher you're using? Only remedy I heard from that (Milaq's CM11 thread, somewhere around page 40) was to just readd them from the app drawer.
Best advice is to wait for todays build to get uploaded and see what happens.
2. You'll need a recovery that has both /data/media support and selinux support. This clockworkmod will do the trick: http://invisiblek.org/tenderloin/openrecovery-twrp-2.6.3.0-tenderloin-selinux.img (thanks @milaq)
Push it to /boot/uImage.ClockworkMod
Great ROM far, I loaded the recovery but i named it TWRP instead because it says TWRP in the file name. It ran as TWRP . Is the above just a typo or can I call it either one?

thank you its working nw
milaq actually has a flashable zip in his thread. that is the easiest. i was on 4.3 went into that recovery, made a backup then flashed the new cwm, rebooted recovery did a full wipe and flashed the rom and gapps and i am up and running. who would have ever thought we would have kitkat on a touchpad. not to mention a 3.x kernel. unreal, thanks for everyones work.

Oops, I had the wrong image there. Link updated with the cwm =P
EDIT: Also added a flashable zip for it, had trouble downloading milaq's so I made my own =/
Anyone else getting a Core Process failure message when booting to the 01012014 Build?
I went back to the 12312013 build and all appears to be back to normal.
To be clear, I went straight to this build from a fresh CM9 image without booting into Android - ever. Got a second-hand device back from a relative, and pushed it to CM11, so it may have been a result of my own process.
I'll reflash 01012014 and see if the error persists.

So am I. Right now I'm using invisiblek's CM 10.2 ROM. It's stable (although a little slow). I don't want to jump to CM 11 again until it is a lot more stable.
BTW, can someone point me to a thread that discusses that benefits of the 3.4 kernel on the Touchpad?

IIRC, a long time ago, someone mentioned that there were some benefits of Jelly Bean that we couldn't use because of the version of our kernel we were using. I would assume the same still applies today if that was the case. Also, with CM11, black boxes are present in many apps that prove them to be unusable. The default browser is unusable on CM11 with the old kernel, so you'd have to either use Chrome, or wait for a new kernel. I'm sure there are some performance enhancements as well.
On todays build, video playback still seems to crash to the home screen with Diceplayer (I could of swore Flint said he fixed that in his build at least). I haven't tested Milaq's test build of the 3.0 kernel to see if that's the same case over there.

One more question for invisiblek, will you be making any updates/improvements to CM10.2 or has all development shifted to CM11? The last 10.2 ROM was on 20131209. I'm having issues with the camera not working..

Also, the old kernel was preventing us from having "official" CM builds.
Getting SoD's once I turn the screen off. Tried the old way to fix that by raising the min clock, but that didn't seem to help. Any ideas?

The 3.4 kernel, minimally, resolves an issues with the other CM11 builds where the core/stock apps were experiencing "black boxes" which prevented users from reading mail, using the browser to navigate and some other issues. Right off the bat, the new kernel resolves that issue.

hey burakgon did you got correct sources from gionee
i heard you were talking to gionee support for problems with kernel sources
pls reply
the sources that have been posted here might be correct but they (gionee) use a different (non standard) mkbootimg to pack it. that leads to issues. simply put, take their boot image or recovery, unpack it, without making any changes, repack it. the new file will be smaller in size. and device wont boot up if you flash them.

not exactly the size of ramdisk but the offset. we need a custom mkbootimg binary. need to edit mkbootimg.c and then re run make recoverytools. try unmkbootimg.

afaik if gionee uses a custom mkbootimg wouldn't they have provided the custom tool to general mobile. if so burakgon could have provided us with same. I at least request him to provide us with general mobile firmware so as to test the theory that they might have made small hardware changes

well, I dont know much about Gionee to assume that it would have given the binary. afaik, it didnt even release the kernel sources.. let alone explain these. then again, I hope Gionee is dev friendly and helps us out. but I can assure you of one thing. Gionee does not use the standard methods. It surely has a messed up software on the device. it took me a week to get adb working properly on the terminal. Hell, I still cant get it to boot into fastboot mode..
P.S., It seems they use some signature for signing the recovery. I just unpacked the recovery and repacked it using mkbootimg. Its initial size was about 11mb. the newer one barely had a size of 8.7mb.
P.P.S., If some one is in touch with Gionee or get in touch with them, please pm..

[ROM][LOLLIPOP 5.1][UNOFFICIAL] Cyanogenmod: cm-12.1 for SM-T705 16gb

This is a build of Cyanogenmod 12.1 for the Tab S 8.4 LTE (SM-T705). This build is based on the last copy I had of Eousphoros' device tree source prior to them being deleted. All credit therefore goes to Eousphoros for the original port. I have only fixed a couple of build errors against the latest 12.1 source.
Please note that although I've checked that the basics are working there will probably be a few bugs. I don't think the device tree I had saved was the latest from the last of Eousphoros' builds so there may even be regressions from his last build. On the plus side the build should incorporate the security fixes in CM 12.1 since then.
I have limited spare time and I'm fairly new to building Android, so in all likelihood I won't be able to fix any issues you have quickly. I'll post a new build from time to time if people are interested, but don't expect daily / weekly builds.
**** Update 06/09/15 - I've made a new build which hopefully fixes the microphone during calls. Link is updated below.
**** Update 31/08/15 - It is my experience that the mobile data is a lot more stable if you have a KitKat radio installed and don't install the Lollipop libs. This is also backed up from comments in the thread I therefore recommend that if you plan on running this Rom you flash a KitKat radio. I use version T705XXU1ANF. I've put a link to this below (use the 'CP' slot in Odin).
Installation
Flash the zip file in recovery (I used TWRP)
Flash Google apps
If your coming from a stock Lollipop rom, rather than Kitkat, then you need to flash the lollipop-radio.zip. (this will give you the correct libs for the Lollipop baseband to get data working.) **** See note above. It is more stable to flash the KitKat modem.

many thanks for your great job !!!! you are the one and only, make offer to load a new CM 12.1 for my 705 !!! must flash it !!! thanks

Thnx @mtdoughty, much appreciated, testing right now.
Hmm, for me, youtube is not working, video wont start to play. Do I need to flash libs or install additinal video players?
Update: oh, youtube works with chrome, but not with the default browser for me ... strange.
@muff99
perhaps it may be that YouTube indeed his own player with brings, but in CM 12.1 the link missing for stock player samsung? I was already with earlier versions. the same can happen if I use the stock player on my ironrom uninstall, because I prefer to work with the MX Player. is just a thought, not a fact.
all things work great
call dial nd ending can b achieved by another external dialer app
bug mic not working unless ur r on speaker phone or headset
Is data working?
Data is working for me but I can barely use the phone for calls as the sound is very bad and drop the call frequently. I've tried with earphones, BT headset and the tab itself with the same bad audio.
Anyone with the same symptoms?
