Be aware that improper usage of kernel features can cause serious damage to your device!
Only use the stuff above if you know what you're doing!
In agreement with the GPL, you can find the sources and defconfig used to compile this kernel right here.
Known Issues:
Please keep in mind that CM12.1 sources are still work in progress. As a result, some features may be broken or only partially working.
That's why I decided to only list device-specific issues below.
Below ~60% battery, the displayed battery level will reduce significantly on rebooting. This is a known issue with all AOSP based ROMs.
After switching to a new battery, I noticed this behavior is related to automatic battery calibration and directly affected by the health of your phone's battery.
Disclaimer:
By downloading and installing this ROM, you agree that I cannot be held responsible for any damage caused to your device while installing or using it. Please keep in mind that it's YOU who chose to do these modifications to your device!
Installation:
Make sure your bootloader is unlocked - if not, follow this guide: Link
First installation? Flash the boot.img from ROM zip via Flashtool (use Fastboot mode!)
Boot into TWRP recovery
Do a factory reset and wipe system partition
Flash latest ROM zip (check "Downloads" section)
Flash suitable GApps for CM12.1 or CM12

FAQ:
How to update to latest build?
1. Reboot to recovery
2. Flash latest rom zip
3. Flash latest gapps linked in OP
4. Flash SuperSU
5. Wipe Cache & Dalvik Cache
6. Reboot
How to safely uninstall this rom?
1. If you were using F2FS, revert to EXT4 before uninstalling!
2. Reboot to recovery
3. Flash neo-uninstall.zip
4. Proceed with the installation steps of your new rom
Should you face storage issues with your new rom, run the following Terminal commands:
Code:
su
chmod 777 /mnt/media_rw/sdcard0
chown 2800:2800 /mnt/media_rw/sdcard0
chown -R 2800:2800 /mnt/media_rw/sdcard0
Troubleshooting:
I can't create folders in internal storage!
Follow the instructions on updating to latest build. While flashing, my rom will apply its required storage permissions automatically.
Alternatively, you may simply run the following Terminal commands:
Code:
su
chmod 777 /mnt/media_rw/sdcard0
chown 1023:1023 /mnt/media_rw/sdcard0
chown -R 1023:1023 /mnt/media_rw/sdcard0
Camera any Gallery won't save my photos!
Follow the instructions on updating to latest build. While flashing, my rom will apply its required storage permissions automatically.
Alternatively, you may simply run the following Terminal commands:
Code:
su
chmod 777 /mnt/media_rw/sdcard0
chown 1023:1023 /mnt/media_rw/sdcard0
chown -R 1023:1023 /mnt/media_rw/sdcard0
I can't move apps to sdcard!
Moving apps to internal storage is quite buggy and discouraged. I recommend repartitioning your device with the instructions below.
Advanced Modifications:
Switching to F2FS:
First of all, make sure you're running homebuild version 20150215 or later!
1. Copy all important files from internal storage to the external sdcard
2. Reboot to recovery
3. Do a full backup (make sure to select external sdcard as target location)
4. Disable MTP in "Mount" menu
5. Go to "Wipe" > "Advanced Wipe" menu
6. Check "System", then tap "FS Options" and "Change FS"
7. Select "F2FS", then swipe to apply the change
8. Repeat steps 5 and 6 for "Data" and "Cache" partitions, as well as internal storage
9. Navigate to TWRP Settings and check "Use rm -rf instead of formatting"
10. Restore your previous backup
12. Reboot to system
13. Restore your copied files from external sdcard
14. Reboot
Reverting to EXT4:
1. Copy all important files from internal storage to the external sdcard
2. Reboot to recovery
3. Do a full backup (make sure to select external sdcard as target location)
4. Disable MTP in "Mount" menu
5. Go to "Wipe" > "Advanced Wipe" menu
6. Check "System", then tap "FS Options" and "Change FS"
7. Select "EXT4", then swipe to apply the change
8. Repeat steps 5 and 6 for "Data" and "Cache" partitions, as well as internal storage
9. Navigate to TWRP Settings and check "Use rm -rf instead of formatting"
10. Restore your previous backup
12. Reboot to system
13. Restore your copied files from external sdcard
14. Reboot
Repartitioning your device:
Note:
Up to 14GB of free space on external sdcard might be required to perform the steps below! (Should be less if your internal storage isn't completely bloated )
The value XXXX used below has to be replaced with a calculated number and varies depending on your desired space. I recommend 5120, as it's a decent balance between general data storage (used for most apps) and space on internal storage for apps with bigger data (games). Refer to step 13 of this link if you want to calculate your own partition sizes.
1. Copy all important files from internal storage to the external sdcard with the following terminal command:
Code:
rsync -P -a /sdcard /ext_card/sdcard0/
2. Reboot to recovery
3. Do a full backup (make sure to select external sdcard as target location)
4. Navigate to "Mount" menu, disable MTP and unmount all partitions listed there
5. Navigate to "Advanced" > "Terminal Command" and type the following code:
Code:
parted /dev/block/mmcblk0 print
This command should display some text like this:
Code:
Model: MMC M8G2FB (sd/mmc)
Disk /dev/block/mmcblk0: 7818MB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Number Start End Size File system Name Flags
1 131kB 2228kB 2097kB TA
2 2228kB 3801kB 1573kB Boot
3 3801kB 5374kB 1573kB Boot2
4 6291kB 27.3MB 21.0MB Kernel
5 27.3MB 28.3MB 1049kB TZ
6 29.4MB 32.5MB 3146kB modemst1
7 33.6MB 36.7MB 3146kB modemst2
8 37.7MB 40.9MB 3146kB fsg
9 40.9MB 46.1MB 5243kB ramdump
10 46.1MB 54.5MB 8389kB ext4 apps_log
11 54.5MB 71.3MB 16.8MB FOTAKernel
12 71.3MB 1359MB 1288MB System
13 1359MB 1621MB 262MB Cache
14 1621MB 3769MB 2147MB Userdata
15 3769MB 7818MB 4050MB SDCard
We're going to remove Userdata and SDCard partitions, so check if these partitions also have the numbers 14 and 15 on your phone.
6. Type the following terminal commands to proceed with resizing the partitions:
Code:
parted /dev/block/mmcblk0 rm 14
parted /dev/block/mmcblk0 rm 15
parted /dev/block/mmcblk0 mkpartfs logical ext2 1621 [B]XXXX[/B]
parted /dev/block/mmcblk0 name 14 Userdata
parted /dev/block/mmcblk0 mkpartfs logical ext2 [B]XXXX[/B] 7818
parted /dev/block/mmcblk0 name 15 SDCard
7. Leave the terminal screen and go to "Wipe" > "Advanced Wipe" menu
8. Check "Data", then tap "FS Options" and "Change FS"
9. Select "EXT4" or "F2FS", then swipe to apply the change
10. Repeat steps 8 and 9 for internal storage (is named "sdcard" in this menu)
11. Restore your previous backup
12. Restore your backed-up files from external sdcard with the following terminal command:
Code:
cp -a /external_sd/sdcard0/* /sdcard/
13. Reboot
14. Enter the following terminal commands to fix storage permissions:
Code:
su
chmod 777 /mnt/media_rw/sdcard0
chown 1023:1023 /mnt/media_rw/sdcard0
chown -R 1023:1023 /mnt/media_rw/sdcard0

By the way, rom is online.

With the whole "no working recovery included", does it mean that we cant flash one to FOTAkernel afterwards?
By the way, you are a freaking champion for releasing this ROM, and thanks for all the work you put into making our phones better

Just doing what I can.
However, I gotta mention that I would never have come that far without @updateing.
Once more huge thanks for your help!
FOTA recovery should work, as the phone boots properly into recovery. You may give this a shot, I remember having seen a FOTA TWRP version by championswimmer in Cross Device Forum. :good:
The problem is that the recovery is not CWM anymore. CyanogenMod team is developing their own recovery at the moment. And that one doesn't work (yet)

Download complete. Gapps server was really slow. For me it took 13 minutes to download only Gapps. Now I'm doing a full nandroid backup.
Edit 1 : Booted. WiFi, Bluetooth and Cellular works fine. I'll report more soon
Edit 2 : Report after 40 minutes of use : Fully stable. Other stuff including camera and root access work completely fine. I just had 1 setting FC at first. This ROM is smooth enough (not as much as expected Lool)
These are all of bugs I found :
1. Setting - bluetooth menu - when searching, that circle animation has some problems
2. Setting - Wireless & networks - More - Cellular networks - Carrier settings makes "com.android.phone" FC. (Maybe it's carrier related )
3. The most important bug I've found (not for me, but it can be a disaster for some others ) is Notification/Battery LED does not work at all.
By the way, I have functional CM Recovery. I was able to boot into recovery by selecting reboot recovery power menu. CM Recovery appeared. Even touch is working fine but there is no backup/restore related option.There was just apply update from zip and reboot.
After all, really thanks for your work it's awesome, as always

Thanks for testing
I think the carrier settings fc and led stuff is device related. Will try to fix it in next build. :good:
Booting in recovery works fine, but flashing does not work.
I'm sure CM team will fix this soon.

Installed in the morning.
Had no crushes yet, no bugs in animation that I`ve seen. However, power consumption is dramatically high compared to stock 4.3 JB. Most time processor runs at 1.5ghz.

Exactly. :good:

Hi
It's my first time to post something so I don't know if I'm doing it right
So
First of all thank you for the ROM and the great work keep it up :good:
Second I found some other bugs Dunno if it's apps releated or something in the ROM itself
1. Gestures keyboard doesn't work
2. Google Play services keep asking to update it "and it's up to date"
3. Tap and hold doesnt work "quick toggles" in notification centre. and is it CM feature ?
An other question
When A new release is out can I flash CM11 kernel to flash the new release since I flashed it using CWM I was on CM11
P.S I didnt wipe data or system wipe just backed up the old ROM and flashed this one didn't want to re-install all apps etc..

Very good looking rom. Flashing right now, got first bootloop....because i flashed cm12 kernel. That was my fault. Now im already setting my device up.
Looks like LTE aslo working.
Any good ideas how to make navibar smaller? Xposed wont work with 5.0 as i know.

Bugs 1 and 3 are related to CM sources. Number two is most likely caused by your dirty installation. (Which I don't recommend, by the way)
Thats the plan.. Until CM recovery works we gotta fastboot NeoKernel and flash the update from its included recovery. :good:

LTE is working? That's great news! :good:
Can anyone confirm this?
No idea how to resize the navbar, but I'm sure CM team will add a customnization option soon.

Temporary Fix for play service
Disable app notifications in settings
Again thank you @WhiteNeo :good:

row, bfq, sio, and vr scheduler support
Governor bug fix. Replace Samsung's interactive governor with default OMAP4 3.0.31 interactive governor from omapzoom.org, plus pegasusq and lulzactive
NFS and CIFS/samba (not loaded by default) filesystem support
LZMA compressed initrd, to keep boot image smaller than 8MB
swap support. zram and cleancache with a working zcache driver, enabled by default
kernel config, insmod configs.ko and then you can access /proc/config.gz
external modem support, for PPP Widget (not loaded by default, P31xx need powered USB hub for external modem)
Some tweaks from gokhanmoral's siyahkernel for S3, passive entropy tweak applied
Remove a lot of debug message from touchscreen driver, display, mmc, modem, etc
linaro arm-linux-gnueabihf- cross compiler, compiler optimization applied
SuperSU v1.41 for stock ROM
Self compiled BusyBox v1.22.0-git in /sbin, config file based on CM's BusyBox bbconfig output. fstrim applet patch applied, android_reboot applet added (a quick but clean port from Android toolbox), swapon applet with priority option. For stock ROM: this version of Busybox will overwrite busybox binary in /system/bin or /system/xbin and save it as busybox.backup
Early boot scripts support (/system/etc/init.d, /data/local/userinit.sh, and /data/local/userinit.d)
Post boot script support (/system/etc/init.post_boot.sh)
For stock ROM: custom boot animation support (/data/local/bootanimation.zip or /system/media/bootanimation.zip if exists, Samsung boot animation as a fallback). If a bootanimation.zip found, the boot sound will be turned off as well as the shutdown animation.
Modified mount options
adb insecure, adb mode in charge state also insecure
Advanced TCP congestion support, westwood as the default congestion
No /system/etc/hosts patch, you can install AdAway from F-Droid

Dual Boot FAQs
Dual Boot FAQs
Adapted from droidphile's "Dual Boot FAQs" with permission.
1. "Why would I wanna dual-boot?"
A. You don't have to.
Suppose you're more of an aosp rom fan. But misses the HDMI out, bluetooth hands-free and love sammy camera more. Do a minimal installation of sammy rom and boot into it when in need of these features and use aosp rom otherwise.
Or you are a sammy rom fan but love the responsiveness and pure android feel of aosp roms.
And while you can dual boot two sammy or two aosp roms, it doesn't make any sense.
2. "What if I don't need dual booting?"
A. No issues. Kernel won't force to setup 2 roms. You can single boot as before.
3. "Will dual booting change my bootloader or do any dangerous stuff like setting my phone on fire?"
A. NO. Changes are at kernel and ramfs level only. Some space in your internal sd card is used, and also the unused hidden partition mmcblk0p11 is used to store cache of second rom. Dual booting doesn't repartition the filesystem or perform anything scary.
4. "I want to setup dual booting."
A. There are four situations:-
1) Sammy rom now. Want to use aosp as secondary.
2) Sammy rom now. Want to use aosp as primary.
3) Aosp rom now. Want to use sammy as secondary.
4) Aosp rom now. Want to use sammy as primary.
Prerequisites for any setup is
a) Flash latest blackhawk's NEXT kernel
b) Flash new ducati vendor blobs (since 1.8.x)
c) Flash latest PhilZ Touch - blackhawk repack version - recovery
d) Atleast 90% battery left.
e) 2 GB free on internal SD.
f) Some spare time
1) Present sammy, setup aosp as secondary:-
i) Reboot into recovery
ii) Flash blackhawk's NEXT tool, create system.img for CM/CM based ROM and then close it
iii) Reboot into secondary recovery
iv) Flash aosp ROM as 2nd ROM
v) Flash blackhawk's NEXT kernel again
vi) Flash new ducati vendor blobs again (since 1.8.x)
2) Present sammy, setup aosp as primary:-
i) Reboot into recovery
ii) Nandroid backup your current sammy ROM
iii) Flash blackhawk's NEXT tool, create system.img for Samsung stock/stock based ROM and then close it
iv) Reboot into secondary recovery
v) Nandroid restore your sammy ROM as 2nd ROM
vi) Flash blackhawk's NEXT kernel again
vii) Flash new ducati vendor blobs again (since 1.8.x)
viii) Reboot into primary recovery
ix) Flash aosp ROM as 1st ROM
x) Flash blackhawk's NEXT kernel again
xi) Flash new ducati vendor blobs again (since 1.8.x)
3) Present aosp, setup sammy as secondary:-
Same as (1), instead of flashing aosp to second, flash sammy to second.
4) Present aosp, setup sammy as primary:-
Same as (2), instead of flashing aosp to first ROM, flash sammy.
NOTE:
-To dual boot Two Aosp or Two Sammy roms, just follow (1) or (2) (depending on which one of them you want as primary/secondary), just flash Sammy instead of aosp or aosp instead of sammy.
5. "What things should I be taking care off while dealing with dual booting?"
A. - Make sure where you are: in primary or secondary recovery.
6. "How to boot into primary rom?"
A. AROMA based boot menu will help you on every boot.
7. "How to boot into secondary rom?"
A. AROMA based boot menu will help you on every boot.
8. "Is kernel partition shared?"
A. Yes. Same kernel boots both roms.
9. "If I flash another kernel (that doesn't support db) do I lose dual booting?"
A. Yes
10. "I lost dualbooting after flashing another kernel. I didn't do anything to second rom files in sdcard/.secondrom. How can I get db back?"
A. Just flash the latest blackhawk's NEXT kernel, flash new ducati vendor blobs again (since 1.8.x)
11. "Will there be any performance degradation on the rom used as secondary compared to primary?"
A. NO
12. "Will my phone run slow overall because of db?"
A. NO
13. "How to flash a newer version of 1st rom?"
A. As usual, just flash it from primary recovery. Flash blackhawk's NEXT kernel again, flash new ducati vendor blobs again (since 1.8.x)
14. "How to flash newer version of 2nd rom?"
A. Just flash it from secondary recovery. Flash blackhawk's NEXT kernel again, flash new ducati vendor blobs again (since 1.8.x)
15. "Would upgrading 1st or second rom cause other rom to fail on boot?"
A. No. Partitions of other rom are not touched during upgrading.
16. "I miss the recovery I used before, so much.."
A. PhilZ Touch not bad at all.
17. "User apps of 1st rom are automatically available for second rom?"
A. NO. However, if you had backed them up using Titanium Backup or similar apps, just restore apps while on second rom.
18. "I wanna keep separate backup for apps in both the Roms, since I use one Rom for say entertainment and other productivity."
A. Setup different backup directory in Titanium Backup in 1st and 2nd rom.
19. "I don't see STweaks app in second rom."
A. This is blackhawk's NEXT dual boot solution for Galaxy Tab 2, a free implementation of gokhanmoral's Siyah dual boot.
20. "Do I need to anything special before flashing a newer blackhawk's NEXT kernel?"
A. NO. Just flash kernel in primary and secondary recovery. Yes, on both 1st and 2nd ROM. Just flash kernel in recovery - whichever you used to do. Kernel image is copied to the unified kernel partition (since 1.4 version). Flash new ducati vendor blobs (since 1.8.x) on both ROM may be required to ensure vendor blobs match to the kernel
21. "How can I run same STweaks settings of 1st Rom in 2nd Rom?"
A. This is blackhawk's NEXT dual boot solution for Galaxy Tab 2, a free implementation of gokhanmoral's Siyah dual boot.
22. "How do I remove everything related to DB and run single boot again?"
A. In primary recovery, flash blackhawk's NEXT tool and delete 2nd ROM system image. OR delete .secondrom directory in /data/media while on 1st Rom.
23. "If secondrom files are kept in /data/media, will wiping data in recovery erase second rom files?"
A. NO. /data/media is skipped in CWM recovery.
24. "I was using ExFat card on sammy rom without any issues. I have setup dual boot with aosp and now after booting into CM it says microSD card is corrupted."
A. Aosp roms doesn't support ExFat out of the box. The data was corrupted by aosp vold. Even if you boot back to Sammy rom, it still would be corrupted. To recover data, manually mount the card in recovery, copy contents to internal SD and reformat card to a Fat32.
Also try
chkdsk X: /f (where X is the drive letter of microsd), you may be able to copy data.
25. "I read somewhere that both rom data partition use the same space. Doesn't that mean my apps are shared across roms?"
A. NO. It just means they uses same partition. They're still different directories.
1st rom data = /data
2nd rom data = /data/media/.secondrom/data
26. "Will hitting "Boot into Secondary Recovery" in recovery boot menu change my recovery?"
A. NO. It just runs (not flash) an alternate recovery so that you can configure dualboot settings.
27. "How do I backup 1st Rom and 2nd Rom?"
A. To backup 1st Rom, do what you did to backup rom while you were single booting a while ago.
To backup 2nd Rom, use the secondary recovery.
28. "Is there an easier way for dual-boot?"
A. Yes, send your device to me.
29. "DB architecture?"
A. Like you know, every rom has a /data, /system, /cache partition and a kernel to boot.
For primary rom, it's
mmcblk0p10 = /data
mmcblk0p9 = /system
mmcblk0p7 = /cache
And these won't change whether you're single booting or dual booting.
For secondary rom, data and system is stored in internal sd, cache in hidden partition. Note that internal sd in our device is mounted to /data/media.
We have data as a directory, System as an image in data/media/.secondrom. Cache in mmcblk0p11 which is hidden partition and not used otherwise.
- When second rom is booting, second rom data is bind mounted to mmcblk0p10 as /data/
- data/media/.secondrom/system.img partition is mounted as /system.
- mmcblk0p11 is mounted as /cache.
More FAQs will be added and the list will be updated as DB is improved.

21/09/2013: OMAP PowerVR 3D GPU Control
There some interface inside /sys/devices/platform/omap/pvrsrvkm.0/sgxfreq:
frequency interface to access the current GPU frequency (153600000/307200000/384000000)
frequency_list interface to access supported GPU frequencies (153600000 307200000 384000000)
frequency_limit interface to access the GPU maximum frequency limit (default: 307200000). Writeable mean this code inside the pvrsrvkm kernel module, the GPU maximum frequency controllable
governor interface to access the current GPU governor (userspace/on3demand/activeidle/onoff)
governor_list interface to access supported GPU governor (userspace on3demand activeidle onoff)
The upcoming version of Android Tuner (0.10.2) support OMAP GPU controls.
21/09/2013: NEXT 2.0.1
As I mentioned before, I still continued cm-10.2 branch kernel development. This branch is the source code of NEXT 2.0, I've added overclock support but limited at 1.2GHz CPU and 384MHz GPU. OMAP GPU controls support applied as gpu_oc interface replacement. Kernel attached here as blackhawk-next-kernel-2.0.1-p31xx.zip .
Changelog:
Rewriting overclock code: https://github.com/kumajaya/android...mmit/35e0c0455cb7ae4beb50375c5873b328a76a1087
Add sysfs interface to store GPU frequency limit: https://github.com/kumajaya/android...mmit/738061b30d2278d3b51b341bc2597dad300f4e47
Limit GPU frequency to default on boot: https://github.com/kumajaya/android...mmit/8a6933cf6565b5587db6a2a5ce7b1207807ab701
Xpad force feedback support disabled
WARNING: This kernel only for device that can handle 1.2GHz CPU and 384MHz GPU frequency.

There is no confusion at all...
Every file you need is in the first post: kernel, tool and Philz. Don't use anything else.
Read the examples. All information is in there...
I don't know about the differences between KK and Philz, but I don't care though... Philz is just great!
Many, many respects to ketut...
Big thanks for your efforts...

PhilZ Touch is a recovery image, NEXT kernel is a boot image, KK-Boot discontinued project.

Ketut @ awesome work with awesome guide.. U explained each n every step clearly for freshers.. N BTW do I need to update Blackhawk next kernel to 1.0..if yes, wiping cache n delvk is necessary before flashing? I am asking u cos I Dnt want to be in mess anymore..

Yes. Fixed the problem when installed CM 10.1 directly as 2nd ROM. No wipe needed.

Please let me ask a question here.
I have already asked in Philz's thread but no answer till now.
Can Philz restore backups made within cwm?
I already have some backups from cwm times and if Philz could restore them that would save me a lot of time. Of course I could just try and see, but that information would be usefull to have before starting in advance.
Please, ketut, any information on that?

Ketut, congrats on your new achievement !
Just one quick question : Can you post all the features (other than dual-boot ability) of this blackhawk-next-kernel on first post ? Or the features are still the same with this :
ketut.kumajaya said:
This is [BOOT IMAGE][GT-P31XX] KK-Boot - Custom boot image for stock 4.1.1/4.1.2 ROM and [KERNEL][GT-P31XX][JB][4.2.2]CyanogenMod 10.1 unofficial kernel 3.0.31 combination, plus cm-10.1-blackhawk commit on github:
Remove Samsung debugging code in ext4 filesystem, inline with omapzoom
Initializing Android USB depending on the rom type, big thanks to gokhanmoral. This is the key of single kernel. Multiboot support not so far, you can reuse my kernel for multiboot (if you can)
Compiler optimizations
Kernel without CGROUPS support
Using SLQB memory allocator
Decrease MPU, IVA, and GPU voltage
Adapt and fix codeworkx's sysfs for controlling pivot mode. This is the key of landscape kernel
Stop the spam from audio driver
An exprimental config, remove a lot of debugging config from kernel: 775MB RAM
Stock JB 4.1.1/4.1.2 ROM: Using a slim version of busybox (from gokhanmoral's ramfs for siyahkernel-sgs3), bash and nano binary, sysrw and sysro script removed. GPU clock @ 384MHz + 2D GPU rendering, stock ROM really need an overclocked GPU.
CM/CM based ROM: As usual, change ro.sf.hwrotation value from 270 to 0 in /system/build.prop will transform your device to landscape mode, a workaround fix for boot animation graphic glitch. GPU clock @ 307MHz + 2D GPU rendering + 16bit transparency + disabled dithering + purging assets allowed
/system/etc/init.post_boot.sh is yours kernel tuning template. But remember, do not force your system too much until you are sure that your device is able to handle it.
Flash this using the latest CWM, CWM Touch, Philz Touch, or TWRP at your own risk!

Couple questions to ketut Please try to answer me - noobie
1) I can flash this for single rom, yes? It should be better than previous version?
2) I can still turn Tab on, press volume down button to boot into CWM?
3) How to turn off the boot menu? (I think I don't need it)

1. Yes as covered by Dual Boot FAQs. No.
2. Yes.
3. Can not be, maybe the next version. Reboot to recovery and bootloader may be removed for security reasons.

Not working
- FM radio.
- Apps that expect newer libOMXVidEnc will not work, Skype is one example. Viber and WhatsApp are working.
- do not use stock browser for serious browsing, although it is working, it has bugs with adreno libs. For 2-step authentication on Google, it will do.
Upstream issues
SDCard not showing unmount option
Trebuchet crashing when you enable CM Home or Google Search as panel
Cyanogenmod stock camera app shows 4.5mp instead of 5 mp - camera works properly with other third party apps and takes 5MP pictures.

How to install:
You must update recovery with this one - TWRP 2.8.6.0 or this one Philz Touch 6.59.0 - ClockWorkMod 6.0.5.1- these two have SELinux support. Philz and CWM do not have support for F2Fs!
Install the recovery trough fastboot
- fastboot flash recovery recovery.img
Reboot to recovery from fastboot
- make a backup of your current ROM to SDCard
- wipe -> do a factory reset
- wipe -> advanced wipe -> select only system and wipe
- install zips (rom and gapps)
- reboot to bootloader
if you are updating from previous CM11, you can dirty flash -> just wipe /system in Wipe -> Advanced Wipe, and install rom and gapps. No guarantees here.
Install boot image
fastboot flash boot boot.img
install boot.img that is inside the ROM that you downloaded
do not do fastboot erase cache
As of RC5, ROM now supports both EXT4 and F2FS in a same installation, and there is an easy way to switch back and forth between full EXT4 and F2FS setup, or any partition layout you would like (why would someone want this, I do not know, but the option is there).
Switching to F2FS from EXT4:
- You must install TWRP 2.8.6.0 with F2FS support.
- install RC5 and gapps (optionally), flash boot.img and restart. Check that the ROM is working properly. Activate advanced reboot in developer options. Reboot to recovery.
- backup - make a nandroid backup of system, data and cache.
- wipe, advanced wipe - select system - change or repair file system - choose F2FS. Repeat this for data and cache.
- settings -> Check use rm -rf instead of format.
- restore -> this will restore your data to existing partitions without format.
- settings -> Uncheck use rm -rf instead of format.
- reboot
You will boot to full F2FS ROM, with all your data and settings intact. Check it out in terminal with
mount | grep f2fs
How to build:
Up to date sources on github. (one patch for legacyMod frameworks_av is missing, will update device tree soon)
1. Follow instructions on initializing a build environment up to a point of downloading the source code.
2. Initialize CyanogenMod 11 repo.
Code:
repo init -u git://github.com/CyanogenMod/android.git -b cm-11.0
3. Add local manifest that downloads HTC Desire C device config, properties and kernel source from my github and few CM replacement projects from legaCyMod github.
Code:
curl --create-dirs -L -o .repo/local_manifests/local_manifest.xml -O -L https://raw.githubusercontent.com/high1/android_local_manifest/cm-11.0/local_manifest.xml
4. Sync source code.
Code:
repo sync
5. Update prebuilts
Code:
cd path-to/cm11/vendor/cm/
./get-prebuilts
6. Apply patches
Code:
path-to/cm11/device/htc/golfu/patches./apply.sh
7. Compile.
Code:
cd path-to/cm11/
. build/envsetup.sh
brunch cm_golfu-userdebug -jx
(x is number of your processor cores -+1)
'repo sync' to pull merged changes from upstream.
'make clobber' to clean the build environment.
Repeat step 7 to make a new build.
FAQ:
Q: I can't find developer options and performance settings, why?
A: Settings -> About phone -> Click 'Build number' several times
Q: I don't have reboot options in power menu, why?
A: Settings -> Developer options -> Advanced reboot
Q: Is ART runtime working?
A: Yes it is. Beware, it is not compatible with xposed framework.
Q: How to make fastboot and adb work with Windows 8.1? (Device enumeration failed error)
A: First, make sure you have this update installed - http://www.microsoft.com/en-pk/download/details.aspx?id=43515 . Unzip http://goo.gl/CAXglZ and merge it to your registry. HTC drivers must be installed, compatible with Windows 8.1 here: http://forum.xda-developers.com/showthread.php?t=2714921
Q: USB tethering does not work?
A: Here is a guide: Android USB Tethering In Windows 8.1

This all would not be possible without help - I looked up alot to KonstaT that makes CyanogenMod for ZTE Blade III, and a lof of this post is taken from his way of posting. KirmaniArslan helped to solve quite a few quirks, and posted patches actively, and started the development - his device tree was made bootable.
I expect logcats from all who will do testing, and hopefully we can fix the remaining bugs and let this device have fully working Cyanogenmod (Omni, Pacman, AOKP hopefully later). Also, with the release, you have full permission to use the source to build other ROMs, only requirement is that if you find a fix, you do a pull request at Github.
Regards, and enjoy the ROM as much as you can.

Adb doesnt work at first boot, so i can't get logcat. All logs what i have - TWRP log.
Cyclic reboot. It works for 2-3 sec and reboots. ANd i cant even look at settings or enable debugging. 2sec and reboot. One thing i'm shure its not from overheating =(
upd:
ok... boot in safe mode gives me 2 extra seconds.. and... there is no developers menu. it is locked. and i cant unlock it.
upd2: nope. i definitely can't attach rom Log and Ksmg.

Try the boot.img inside the ROM then. But it should not behave like that. Wipe the system along with the factory reset.

I'm having problems with TWRP v 2.8.0.0 recovery. I was using clokwork before and after flashing my log gets spammed with couldn't mount emmc. Adding full log
Adding link to pastebin, because for some strange reason I got error in forum that file was invalid
http://pastebin.com/iRgFm13z
Sorted out this issue, but rom seems to be stuck on bootloop.
Added logcat

Ok. For me "How to install" must looks like:
1. Install the recovery trough fastboot
2. Reboot to recovery from fastboot
3. install zip
4. reboot to bootloader
5. Install boot image
6. reboot
Mb is is caused by S-OFF, but I rly need to flash kernel only after flashing zip. Work with "normal" kernel.
Upd1: Does ART works? Cause it looks like it works.
Upd2: OMG ART rly works. Can't belive it =)

Flashing the ROM does not affect boot partition, because of S-OFF. Order of instalation (boot image first) should not affect booting. I enabled zRAM kitkat style in latest build, as you requested - we are compliant with Google recommendations for low RAM devices now. I forgot to say, yes but ART is working without any problems, as long as apps work with it.

I forgot to say, yes but ART is working without any problems, as long as apps work with it.

ART it's rly cool surprise =) Nice =)
As for S-OFF, i rly think u cant make changes with boot if u phone is S-ON. When u swith it to S-OFF u can make changes from recovery. Any way i have no other explanation, why order is important for me. i'll try to test it =)
UPD: is there any trick in win8 for adb? cause for me adb works only from my linux laptop.

Yes, there is. Import this in your registry - you must have a patch with workaround installed, http://www.microsoft.com/en-pk/download/details.aspx?id=43515
extract reg file from attached zip and merge it to your registry.

I'm having problems with USB mass storage. First time when I click to turn it on, it unmounts sd card, but I'm not able to access sd-card file on PC. Second time I click loading loops forever.
Have anyone encountered similar problems?

It's ums file setting, looks like it. I chose MTP as default, as mass storage requires mounting, unmounting etc... Will be fixed in the next build. Thx.

Known Issues:
Please keep in mind that CM12.1 sources are still work in progress. As a result, some features may be broken or only partially working.
That's why I decided to only list device-specific issues below.
Below ~60% battery, the displayed battery level will reduce significantly on rebooting. This is a known issue with all AOSP based ROMs.
After switching to a new battery, I noticed this behavior is related to automatic battery calibration and directly affected by the health of your phone's battery.

FAQ:
How to update to latest build?
1. Reboot to recovery
2. Flash latest rom zip
3. Flash latest gapps linked in OP
4. Flash SuperSU
5. Wipe Cache & Dalvik Cache
6. Reboot
How to safely uninstall this rom?
1. If you were using F2FS, revert to EXT4 before uninstalling!
2. Reboot to recovery
3. Flash neo-uninstall.zip
4. Proceed with the installation steps of your new rom
Should you face storage issues with your new rom, run the following Terminal commands:
Code:
su
chmod 777 /mnt/media_rw/sdcard0
chown 2800:2800 /mnt/media_rw/sdcard0
chown -R 2800:2800 /mnt/media_rw/sdcard0
Troubleshooting:
I can't create folders in internal storage!
Follow the instructions on updating to latest build. While flashing, my rom will apply its required storage permissions automatically.
Alternatively, you may simply run the following Terminal commands:
Code:
su
chmod 777 /mnt/media_rw/sdcard0
chown 1023:1023 /mnt/media_rw/sdcard0
chown -R 1023:1023 /mnt/media_rw/sdcard0
Camera any Gallery won't save my photos!
Follow the instructions on updating to latest build. While flashing, my rom will apply its required storage permissions automatically.
Alternatively, you may simply run the following Terminal commands:
Code:
su
chmod 777 /mnt/media_rw/sdcard0
chown 1023:1023 /mnt/media_rw/sdcard0
chown -R 1023:1023 /mnt/media_rw/sdcard0
I can't move apps to sdcard!
Moving apps to internal storage is quite buggy and discouraged. I recommend repartitioning your device with the instructions below.
Advanced Modifications:
Switching to F2FS:
First of all, make sure you're running homebuild version 20150215 or later!
1. Copy all important files from internal storage to the external sdcard
2. Reboot to recovery
3. Do a full backup (make sure to select external sdcard as target location)
4. Disable MTP in "Mount" menu
5. Go to "Wipe" > "Advanced Wipe" menu
6. Check "System", then tap "FS Options" and "Change FS"
7. Select "F2FS", then swipe to apply the change
8. Repeat steps 5 and 6 for "Data" and "Cache" partitions, as well as internal storage
9. Navigate to TWRP Settings and check "Use rm -rf instead of formatting"
10. Restore your previous backup
12. Reboot to system
13. Restore your copied files from external sdcard
14. Reboot
Reverting to EXT4:
1. Copy all important files from internal storage to the external sdcard
2. Reboot to recovery
3. Do a full backup (make sure to select external sdcard as target location)
4. Disable MTP in "Mount" menu
5. Go to "Wipe" > "Advanced Wipe" menu
6. Check "System", then tap "FS Options" and "Change FS"
7. Select "EXT4", then swipe to apply the change
8. Repeat steps 5 and 6 for "Data" and "Cache" partitions, as well as internal storage
9. Navigate to TWRP Settings and check "Use rm -rf instead of formatting"
10. Restore your previous backup
12. Reboot to system
13. Restore your copied files from external sdcard
14. Reboot
Repartitioning your device:
Note:
Up to 14GB of free space on external sdcard might be required to perform the steps below! (Should be less if your internal storage isn't completely bloated )
The value XXXX used below has to be replaced with a calculated number and varies depending on your desired space. I recommend 5120, as it's a decent balance between general data storage (used for most apps) and space on internal storage for apps with bigger data (games). Refer to step 13 of this link if you want to calculate your own partition sizes.
1. Copy all important files from internal storage to the external sdcard with the following terminal command:
Code:
rsync -P -a /sdcard /ext_card/sdcard0/
2. Reboot to recovery
3. Do a full backup (make sure to select external sdcard as target location)
4. Navigate to "Mount" menu, disable MTP and unmount all partitions listed there
5. Navigate to "Advanced" > "Terminal Command" and type the following code:
Code:
parted /dev/block/mmcblk0 print
This command should display some text like this:
Code:
Model: MMC MAG2GA (sd/mmc)
Disk /dev/block/mmcblk0: 15.6GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Number Start End Size File system Name Flags
1 131kB 2228kB 2097kB TA
2 2228kB 3801kB 1573kB Boot
3 3801kB 5374kB 1573kB Boot2
4 6291kB 27.3MB 21.0MB Kernel
5 27.3MB 28.3MB 1049kB TZ
6 29.4MB 32.5MB 3146kB modemst1
7 33.6MB 36.7MB 3146kB modemst2
8 37.7MB 40.9MB 3146kB fsg
9 40.9MB 46.1MB 5243kB ramdump
10 46.1MB 54.5MB 8389kB ext4 apps_log
11 54.5MB 71.3MB 16.8MB FOTAKernel
12 71.3MB 1359MB 1288MB System
13 1359MB 1621MB 262MB Cache
14 1621MB 3769MB 2147MB Userdata
15 3769MB 15.6GB 11.9GB SDCard
We're going to remove Userdata and SDCard partitions, so check if these partitions also have the numbers 14 and 15 on your phone.
6. Type the following terminal commands to proceed with resizing the partitions:
Code:
parted /dev/block/mmcblk0 rm 14
parted /dev/block/mmcblk0 rm 15
parted /dev/block/mmcblk0 mkpartfs logical ext2 1621 [B]XXXX[/B]
parted /dev/block/mmcblk0 name 14 Userdata
parted /dev/block/mmcblk0 mkpartfs logical ext2 [B]XXXX[/B] 15.6GB
parted /dev/block/mmcblk0 name 15 SDCard
7. Leave the terminal screen and go to "Wipe" > "Advanced Wipe" menu
8. Check "Data", then tap "FS Options" and "Change FS"
9. Select "EXT4" or "F2FS", then swipe to apply the change
10. Repeat steps 8 and 9 for internal storage (is named "sdcard" in this menu)
11. Restore your previous backup
12. Restore your backed-up files from external sdcard with the following terminal command:
Code:
cp -a /external_sd/sdcard0/* /sdcard/
13. Reboot
14. Enter the following terminal commands to fix storage permissions:
Code:
su
chmod 777 /mnt/media_rw/sdcard0
chown 1023:1023 /mnt/media_rw/sdcard0
chown -R 1023:1023 /mnt/media_rw/sdcard0

Loving you right now,as this is a new version of Android, if I am coming from 4.4 KK do I need to flash boot.img before right?
Thanks

Now I am in my village without a working internet until January, sorry, I'll see if I managed to download your ROM somehow, I can't wait!?
Happy New Year!

Yes, At last... I'm downloading and testing this right away i've been waiting for this

bro what can i say..you did it! your the man! thank you so much!! Working like a dream!

Thanks mate
Really, thank you WhiteNeo!
Actually: Why is it in "original Android dev"?

Been running for a few hours and i just want to congratulate you once again!
just one minor thing that im sure you already know but i'll point out ..keyboard gesture isn't working..
That's literally the only thing i have noticed that is not working

Because it's built from sources and so on and so forth.

So in this case 'original' means the AOSP sources? I thought it meant sth like 'based on the original (=stock) ROM'.
@WhiteNeo: Is it possible to link the sources?
Found Bugs (CM or device specific?):
- Calculator Button Widget behaves strangely (not the 'big' widget)
- Themes Showcase doesn't change tab (eg. to Wallpapers) and Options makes it crash.
Both theme to be general issues I think

Keyboard gesture won't work on AOSP because it requires a proprietary lib by Google. You can install Google Keyboard to have the same look with swype
Alternatively, check my XV CM12 thread for the material Xperia keyboard I attached to one of my latest comments.

Thank you very much WhiteNeo. You are giving our phone a new live.
By the way, for people that has tried it yet, what about camera quality? Is it better than 4.4 cyanogen roms?

Google Search Bar
The Search bar sometimes has display issues, that is the icons on it arent displayed anymore.
On my previous post: It should be @WhiteNeo of course, didnt know it would automatically link it

All of the bugs that have been mentioned so far appear to be sources related, so no need to post them here.
I recommend creating a new issue at https://jira.cyanogenmod.org if you detect any bugs that are obviously not related to our phones' hardware.

Thanks for the build! The ROM is super smooth and bug free for me so far, except maybe the front camera being fuzzy when i tested it. I'm going to try and see how long i can live without xposed. Great work!
Oh wait.. snapshare doesn't work. ****!

I've got a glitch - mobile data is on, but the "H" symbol is gone. Meaning there is no "H". Up-and-down arrows are in place when data is being transmitted, but no "H". Other than that everything's just fine.

My feedback
Everything works well..
im amazed by this new experience..
Some things i've noticed
- From facing camera stretches the image from camera sometime
- I experienced whistle from speaker while calling, however, i flashed a zip, which fixed it, i will attach the zip file
other than that, everything is working well in my point of view..
i will post more soon if i come across some..

Guess that's an issue in upstream.. Should be fixed in next build

i have it all ready but didn´t have time to install,i´m still on 20150915 tomorrow i´ll try this one

Finally.. you created thread. Thanks for your work and continuing support for this device

Thanks neo, this rom with include saber mod, can i use other mod ?

Working good so far, it's got the extra settings/customization that the only other build for TX lacks. No problems so far with bootloops, data restore, etc. except for the issue I think was already mentioned in the T thread, in which TWRP doesn't reboot and hangs if you press the "reboot" button too soon.
:good:

hi
I Installed last version of TX rom
Now Bug Report:
1- in mobile network operation i can't See 2G Or 3G mode and select it manually

There are enough Xperia apps out there already. Any app that works with CM12 on any phone should work with this specific ROM, too.

Look here.
https://www.google.de/search?btnG=1&pws=0&q=xperia+apps+cm12.1+site:forum.xda-developers.com
Camera button stuff is one of the features that have to be added in upstream sources first.

1 problem by this device is low storage for app installing
this device have 16Gig Storage
but we can install 2Gig app!
if you can Increase this storage many of problems was solved
(for example my galaxy tab have 16gig storage and i can install 16gig app on my device)
thank you

Hi. Got to hand the phone. I want to upgrade to the current release. Can I rolled forward as an upgrade, or better to install as the installation for the first time? Or enough to make a backup and then to roll back? (exactly what to back up that it include?)
sorry for my bad english.

Check the instructions in third post
You can always do a backup before updating, but I test the builds before upload, so a bootloop or other issues are quite unlikely.

​
I have ported this device to Android Linux kernel v4.4. This is the official Android kernel for Oreo. This ROM requires a completely new kernel and recovery. Read everything before use.
​
Recovery - TWRP BigSys
TWRP BigSys will use a different partition layout in order to have a larger system partition size.
Flashing TWRP-Bigsys with odin/heimdall will overwrite the cache partition. Format the cache partition it in recovery after flashing with odin/heimdall.
Partition layout:
Code:
Before:
[ system (578MB) | cache (448MB) | data (16GB/32GB) | hidden / preload (300MB) ]
After:
[ system (1026MB) | data (16GB/32GB) | recovery extra (16MB) | cache (284MB) ]
TWRP BigSys is not compatible with any ROM before Oreo.
BigSys partitioning is based on BigPart for Motorola Xoom.
Kernel - Linux v4.4
This is based on the official Android common kernel. The drivers and platform specific parts ported from the original 3.1.10 kernel.
Working
Code:
Tegra 2 platform
Downstream video/avp
Dynamic voltage and frequency scaling
USB (ConfigFS)
- no host mode
Voltage Regulators / Battery / Charger
tps6586x
stmpe811

Misc
Samsung misc partition. (Stores reboot mode and proprietary control bits)
Samsung LPM (off mode charging)
Will not work
Code:
3G/Cellular modem

tegra usb phy hsic
- No mainline kernel driver for this USB interface
Cameras / Flash
s5k5ccgx
s5k5bbgx
- Incompatible camera stack
HDMI
sii9234
Samsung 30-pin connector
keyboard dock, dongles, accessories
Functional differences
Code:
Enable force usb charging at kernel boot (rather than android init).
Add haptic vibration strength.
ROM - Android 8.0 Oreo
The ROM is AOSP based.
It is one ROM and recovery for p4wifi (GT-P7510), p4 (GT-P7500), and p4tmo (SGH-T859) since 3G/cellular will not work in the kernel. There is no difference between the two devices other than the cellular modem.
Customizations:
Advanced reboot menu
NEON emulation
Apollo music app
Working / Not working:
See the list under the kernel section.

Add feature to new kernel
Would it be possible to add in the kernel the neccessary things for pelya usb keyboard. Google search for pelya usb keyboard and there is a github with all the code needed to be inserted into the kernel to make the usb keyboard work.

Hi,
this is the log, I'm not sure whether I've done everything correctly..

Can I flash this rom on over the existing 20171005 version? Thanks.

Yes. It is the same ROM. Only the kernel is different.
This not meant for regular use. It only posted in order to get kernel logs and feedback on the issues in the first post. I will not maintain this kernel for regular use.

@decatf
my panel seems to be the lsi one so I'm afraid my log is rather useless for you?!

Hi @decatf,
Thanks very much for doing this. Attached are the logs. The processor has no problem switching to different clock frequencies.

System was booting fine with 3.18 on my P4, please find the output of cmdline and clk_summary attached.
Kind regards, mistersixt.

I will try to test my tab on weekend

It has an issue rendering text, but nothing a reboot can't fix, aside that it's working fine.
I cann't upload files, so I'll send you a PM with syslogs.
Thanks for your time.

Rom works ok, Xposed bootloops, screen turns on and off.
I can OC CPU to 1,5GHz with no problem.

Updated first posted with Oreo ROM, kernel, and recovery.
Nobody sent any logs with the CMC623F panel so that remains untested.

Hi decatf. I tried testing the kernel when you first posted it but I couldn't get past boot loops. After restoring a nandroid back up, I follwed thw instructions for a clean install with the following esult:
Backup all data to a location off the device.
Install and boot into TWRP BigSys
Format system partition
- Wipe > Advanced Wipe > Check "System" > Swipe to Wipe
Reboot to TWRP BigSys

Your device has a different eMMC chip and partition locations than my device. I had not expected this. The BigSys partitioning is only coded to work when it sees the expected partition layout to convert.
It only means that I need to write some code to handle whatever different eMMC chips there are. So you'll have to wait for now until that's done.

OK, cool. Thanks very much decatf. :good:
