Actually I am a kernel developer for Galaxy R I9103.
However as our device almost shares all the same things as the P7510 / P7500 one, such as same PIT file as well as using a slightly different tegra 2 platform, it is interested to know how much users have experienced brick / freeze problem after using the ICS update.
And I guess it is all due to a problem found in ICS update for both P7500 / P7510 and I9103.
So may I ask how many of you have experienced brick / freeze problem after using the ICS update?
If you have experienced these problems constantly, please vote 'Yes, I am experiencing these problems constantly'.
If you have not experienced these problems, or these problems just happened rarely, please vote 'No, I didn't experience these problems constantly.'.
If you are only using GB firmware, please do not vote in this thread please.
btw, if you have experienced these problems, please download 'eMMC Brickbug Check' from play store and select the 'Check Memory' test from the application.
If the android framework freeze during the test, please reboot your device by re-plugging the battery in or long pressing the power button for about 10 seconds. And then please report back your eMMC chip info here (as your device cannot pass the test).
P.S. I am doing this because I am trying to see if the eMMC bug is existing on the Samsung tegra2 platform or not. And getting some statistic info would be good enough to determine whether our device has the bug or not.
Hello
I recently installed my first rom - SlimBean 4.3.1 bulid 2.2
The rom works fine but after 1 week i noticed my battery start to drain very quickly.
I check with GSam Battery Monitor and i found out that *kernel* eat most of my battery.
I want to change the kernel.
which kernel will save my battery in a better way?
My current kernel is: 3.0.80+

Dan,
Can you give a little more information? Type of phone, which version of Android you upgraded from etc?
I can't say that I've encountered any battery drain issues with Slimbean in the past..... it's only ever helped things.
The only question I'd ask is did you follow the correct instructions when flashing? (deleting / formatting all of the cashes etc don't just do a factory reset). Your probably a very clever guy who did everything correctly - but it's the only thing I can think of.
I'd try re-flashing following the instructions on the slimbean website to the letter......
Hope this helps

So, does this mean, there is no option to use a custom kernel for Slimean 4.3 build 2.2? I am on i9300 on Slimean 4.3 build 2.2...

He didn't say that. He was asking Dan did he correctly followed the installation procedures or not, because issues sometimes caused from previous rom installations leftovers (not properly wiped).
And to your question, custom kernels is just a matter of individual preference. You may install any kernel as long as they are compatible with slimroms.
Although any issues caused by other kernel shouldn't be discussed in slim threads. But if you're using stock slim kernel and having problems then you may report to the devs, but make sure that problems aren't listed on the OP's Known Issues, and also provide feedback support files such as logcats or screenshots so the devs could identify the problems right away ?
Battery drainage issues
Hello,
I have recently installed SlimBean 4.2.2 on my Xperia S.
This is my first custom ROM and my previous OS was Stock 6.2.B.1.96.
Needless to say I've rooted my phone (using DoomLord's Technique), have CWM Recovery 6.0.3.0 and Unlocked the bootloader.
I had cleared data, cache, dalvik Cache before flashing the Slim-nozomi-4.2.2.build.8-OFFICIAL.zip and Slim_Gapps.4.2.2.build.8.zip
Issues:
Heavy battery drain - I left my device overnight with all radios off (Airplane mode) and the device registered a loss of 10% in battery level [ 2 Screenshots attached ]
The GSM network radios doesn't turn on when I change the Airplane Mode toggle in Notification Bar
Unrelated - How do I use the AIO_Addons.zip and AIO_Aroma.zip?
Unrelated - Does flashing a Custom ROM mean that Google Apps won't be updated via Play Store? ( Tried once - got invalid signature error )
Steps taken to remedy this (Beginner level):
Installed WakeLockDetector app to find what's up with the ROM. Turns out Google Search had maximum wakelocks [ Attached Screengrab ], despite me Greenifying the app.
I've greenified Google Search app and couple of other network accessing apps (like feedly, pocket, FalconPro (twitter client) )
Dear XDA-ers, kindly help me remediate this issue, as I truly like the ROM..but I'm sure such issues can be solved. Otherwise It wouldn't be the stable ROM that it is.
Please let me know if any other information would be helpful.
First post here, apologies if I may have offended anyone's sensibilities.
Recently I found this interesting Tool ... and I successfully flashed "Allminipc_ug802_RT8188_4.4_720p.img" (Kitkat version) on my MK802 III using Debian Linux 7.5!
Regards, mistersixt.
In case someone is interested: I successfully installed the rk3066 drivers for WinXP using Moborobo, rooted the device with the kingo root tool, and I was able to installed the xposed framework 2.6, too, including XPrivacy, root cloak etc.
So I have a fully 4.4.2 running MK802 III with root access and Xposed framework!
Regards, mistersixt.

Very interesting..Any chance you could share the firmware image file and also let us know how has it been so far...is it fast enough and does the Wifi and Camera (UVC drivers compatible) work w/ this ?
Also could you confirm if this is for MK802III and not MK802IIIS...

It is the MK802III, and the stick is running fast and stable. Wifi is as bad as with 4.1 ... but I think this is a general (or hardware related) issue, I am using it with a USB to LAN adapter anyway.
Concerning the camera I have no idea.

Hi,
Thanks for your response.
I've just installed this firmware on my MK802III and it seems no audio video app is working properly. Youtube does not show any video or sound. Neither can I play youtube in the browser.
No streaming media player works either. Only the local media files are playing properly.
The playstore seems to take ages to install apps because of speed, however when I check the internet speed using speed testing app it gives a good enough speed of 7Mbps.
Also i've noticed that there the wifi network connections are getting dropped abruptly. The wifi connection itself seems to be OK but connection from apps such as Airdroid drop out and upload from my local machine via Airdroid takes ages w/ speeds in Kbps.
Can this be fixed please.
Thanks,
OP

MK802IIIs up and running
Works brilliantly on my MK802IIIs. Wifi is strong and Bluetooth works out of the box. Already rooted and CWM recovery installed. Now its time for some Xposed magic! Anyone has an idea which XBMC version will run best on this?
I'm using the ROM from this thread http://freaktab.com/forum/tv-player...73-full-1080p-modded-kit-kat-4-4-2-rk3066-rom
Super fast and stable, its like a new machine coming from the old JB ROM I had on there. I can actually use it now.
This ROM is for an Imito device but the MK802IIIS is identical hardware.
Few OC kernels in that thread to to play with.

Hi,
The rom seems nice but I just can't get it to run correctly on my MK802IIS. I just flashed the rom on this thread (V 1.1 ) without flashing a custom kernel. Just flashed the entire rom. And after the first boot, I see the apps update (the optimization screen) and then I'm stuck on the screen where there is an Android icon on the top with a blue bar underneath. This screen just keeps blinking and seems to be impossible to pass. I can access the settings, but I found impossible to activate wifi or lan.
Ozzy, you seem to have a MK802IIIS, did I miss something during the flashing? Do I need to flah a custom kernel after flashing the rom?

Did you do a full wipe?

Yeah I did a full wipe, that's why I don't understand what's happening to me. I see someone on the thread has the exact same problem, but doesn't precise on which device, so I preferred to ask you first, as we have the same device.
I'll just try the v.1.0, mabe that 1.1 version doesn't run on my key. Did you flash the 1.1 or the 1.0 ?

I've been using mine daily since I posted last time. It works fine except for some hick ups.
Sometimes during bootup it hangs with just 3 penguins on the screen.
And I'm running out of internal disk space all the time. I never did that on the official 4.2 even though I had many more applications installed then. Any ideas how to fix that?

@Kosh_swe, have you found a solution? I also failed to get the Vanir ROM to work and I'd consider the flox CM10.2 ROM. Your post suggest that my radio would be dead in flox, too.

Hey guys,
I recently compiled flxo CM11.0 rom with STE OMX support (from TeamCanjica).
I've been testing it for a couple of weeks, for me everything seems ok (no reboots, camera working ...)
I didn't test bluetooth hand's free, but it's certainly still broken.
You can download this rom from my dropbox account :

Testing radio issues
Hi to all,
I just tested radio issues on my phone. I was researching, why radio is not working.
Here are results, maybe it will help. Anyway, I have my GT-s7710 for testing and I can do some tests or catch some debug informations if needed.
It seems that problem why radio is not working is located in modem-supervisor process. In original firmware, this process is responsible for uploading firmware into dbx500 platform chip. But in CM, there is no such process.
I am not expert, but it seems to.
I tried to use old modem-supervisor process to make everything working.
Services line from original fw:
Code:
service modem-supervisor /system/bin/modem-supervisor -r -f /dev/dbx500_mloader_fw -i /sys/devices/platform/ab8500-i2c.0/chip_id -c monitor -t 0
but it needs to be changed because /sys/devices/platform/ab8500-i2c.0/chip_id changed to /sys/devices/platform/ab8505-i2c.0/chip_id
Problem is that firmware event for loading firmware is never generated and firmware is not uploaded.
I have some dumps and traces if you need them. Thank you for your work!

Your "tested" devices are just headphones, right?
The Problem is not the hearing part - the microphone signals are blocked...
if you have a real headset - please try with that one again and tell me
an idea
The 7580's phone hardware is almost identical to the 7710. The processor in the 7580-higher heights, but the hardware buttons and then there are all of the functions, but it has the 4.2.2 firmware, which allow moving to the SD card. Somehow it should possess to operate from 7710.
I'm Hungarian, sorry if the translation is wrong, happened with google.

After clean 1st boot after the installation the buttons are working perfectly, but after reboot (2nd boot) they are not working properly. Only long presses are working (google search by long press of menu button, kill aplication by long press of back button, last apps by long press of home button).
So? There is no such responde on how to fix that..!

XCover 2: BT hands free - Problem fixed yet?
Hey developers,
I was wandering if the BT problem has been fixed for Cyanogenmod Version 10.2 for XCover 2.
BT hands free. Connection/pairing works, but the audio path is broken.
Thanks a lot!
baseband wipe
I can't get Cyanogenmod 10.2 working. Everytime installation wipes my baseband.
When I install the Stock ROM SIM works again - but after flashing CM again also wipes baseband again.
My Installation-Tools:
Odin v3.07
CMW: 20140112_cwm-6.0.4.6_skomer_fixed.tar.md5
CM: 20140204_cm_10.2_skomer-ota-eng.flx.zip
Is there any chance to install the baseband (I think it's inside the modem.bin)?
No network available in Polish Play
I'm installing CM for my father in law on Samsung X Cover 2 and I'm facing problem with no available network.
I've tried CM 11 and CM 10.2 - both are running fast but both doesn't recognize any network operator.
CM11 has additional problem with hanging during shutdown.
I've found that Polish network Play has common problems with radio: like here
https://code.google.com/p/cyanogenmod4milestone/issues/detail?id=510.
But even I'm putting T-Mobile sim card then still phone doesn't recognize (phone is coming from Play but it is unlocked).
When I restored Play stock ROM then it works.
Could anybody help in this?
I cannot point link to logcat because new user limitation - pastebin URL part is rWttd9PH

Forget CM en try Vanir or MIUI these are more up2date. Also CM11 is alpa with camera bug:
First look at: http://forum.xda-developers.com/t/xcover-2
Vanir
Second, I use Vanir 4.4.4 daily. It has some bugs, but not some bugs that makes it unstable. Known issues:
Start/Stop navbar after every restart
Use this solution to fix connection errors after a fresh Flash: http://forum.xda-developers.com/showpost.php?p=60411469&postcount=612
Other small bugs:
2G/3G quick setting and normal settings dont work properly because of absence of LTE
Navigation Ring and immersive mode causes dead touch screen space
DSP manager doesn't work
After using Vanir 4.4.4 I never want to go back! It's that much faster, more free RAM en better battery performance. Because of the better RAM performance, you must kill apps more often else it will drain the battery quicker :silly:.
Best way to Flash with 4.4.4 is to first flash Clockworkmod through ODIN, then do the usual Full Wipe --> Wipe Cache --> Flash Rom --> Flash GAPPS. Here is a video of someone doing these things. P.S. in this video the process is speeded up also reboot can freeze the system (just remove battery after a couple of minutes)
Files
Vanir: https://drive.google.com/file/d/0B7agwkTbiz0pNHZMQlpudkR4NUU/view
GAPPS: https://mega.co.nz/#!kokjzJwT!eqmMam5r5N2kWvtmSMy4QnaHnxvoqhDtr_joSDU5anI
MIUI
Another option is MIUI (used on the the popular Chinese Xiaomo phones). Instead of the Vanir build, this build is still being maintained. But because it's based on Vanir it has most likely has the same bugs. Never tried it because I prefer stock Android.
2nd, the connection error fix for vanir could also work for CM (vanir uses stuff from CM).
Since the development thread is closed by OP request( sad but true ), and personally building a "port" of the ROM, i'm glad to help everybody as i can, with this thread.
It doesn't mean to be a development thread since i only build and implement some changes, but just to share comments, issues( like xposed one ) or just ideas to people who own this device ( CN or ROW ).
As a reminder you can find my builds here: LINK or just use OTA function in ROM.
And a big thanks to @frantisheq and @Electry for the works on CM13, and for the next, CM14.

Are someone try to flash Vibe Z2 (NON PRO) with this ROM?
don't do it, you will probably brick the phone.

Uploaded new build!
Should have Dec 5 patches, have a nice day
Try to install the latest build together with xposed. There is a boot loop with CM logo...... It seems to me there was such kind of problem......
That should be fixed by cm ? . Will apply the xposed fix in next build.
Thanks to inform me about this!

updated build, with xposed patch, hoping now works fine
The latest build works fine for me. I installed it with xposed.
Hey @malaga82
I have a strange feeling that the new ROM is worse in performance compared to the previous build. It has way more stutters and sometimes the system UI resets and changes my wallpaper to the stock one. Anyone else facing such issues?

Could you please provide more details about this behavior and I try to reproduce it? Now I have not such kind of problem. But I can say that the UI sometimes has strange behavior. For example, the horizontal size of quick settings can be more widely than the size of the screen.
maybe it's something related to CM repo's and they will fix "soon".
give some days to see if they fix anything, i'll provide a new build.
In additional to my previous report I would like to add that the latest build cannot hold loading. At the previous build from 16 Nov I can run at the same time a navigation application and a video registration application. Now I cannot do the same because the device is rebooting due to overheating. I tried to figure out what is going on and found that the high limit of CPU0 temperature is set up to 85 C (it seems to me it is low....) and I cannot change it – try several tuning tools. And it is not only one reboot – there are several reboots….. After its a Bluetooth pairing was lost….. And I can repair a normal work only wipe cache & dalvik through TWRP and pair a Bluetooth once again…..
i'd like to have more feedback if possible.
i'm thinking to try to build with the "old" kernel that have cpu voltage control and other features i included times ago.
atm we are a bit stuck with development.

Solved games issue.
Hello!
Sorry for my English, I from Russia.
On roms later CM 13 2016.03.07 in file: build.prop, increase the value: dalvik.vm.heapsize= from 512m to 768m. This led to the errors in game Real racing 3 (insufficient free memory, missing textures, game crashes). With value 512m games work fine.
If install Adreno drivers from ROM CM 13 2016.03.07, game Gear.club also work fine. The difference can be noticed immediately after starting the game.
I also sent this message to frantisheq.
Happy new year!
Solved games issue.
Additional information to the previous post.
I was looking the file: default.prop, and the parameter ( dalvik.vm.dex2oat-xmx ) is set to =512m. System parameter ( dalvik.vm.heapsize=768m) overlap kernel parameter. Possible, if rebuild kernel with the value 768m, all be fine? I don't test this.
