BIG FAT WARNING:
NEXT kernel 1.0 - 2.0 requires mali-400-r3p2-01rel3-t31x.zip!
NEXT kernel 2.1 and later requires mali-400-r3p2-01rel3-api29-t31x.zip!
Sources:
Kernel sources at https://github.com/kumajaya/android_kernel_samsung_smdk4x12/tree/cm-11.0
Features:
Based on Samsung OSRC Note 2 N7100, Tab 3 8.0 and Note 8.0 kernel source
Single source for T310, T311, and T315 target (and Note 2 N710x, Note 8.0 N51xx). Only T311 version well tested on my device but both T310 and T315 version boot T311, not working GSM radio of course
Traceable source level changes: https://github.com/kumajaya/android_kernel_samsung_smdk4x12/commits/cm-11.0
Open source Samsung exFAT modules included
Remove a lot of debug message from touchscreen driver, display, mmc, modem, bluetooth, etc. Now, dmesg output more useful than stock kernel
Disable a lot of kernel debugging support
Linaro GCC compiler
The ramdisk based on JB 4.2.2 AMG3 (T310 and T311) and AMH1 (T315), OTA recovery flash disabled
Some tweaks from gokhanmoral's siyahkernel for S3, passive entropy tweak applied
Auto root, SuperSU included please download SuperSU from Google Play. Heimdall v1.4.0 work for our device. For a brand new T31x, flash your device using "sudo heimdall flash --BOOT boot.img" and you will get rooted
Self compiled static BusyBox v1.21.1 in /sbin, android_reboot applet added (a quick but clean port from Android toolbox), swapon applet with priority option. On 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)
Mali GPU driver r3p2-01rel3
KitKat external sdcard write access for user apps patcher
Known Problems:
Thanks To:

Directly flash mali-400-r3p2-01rel3-blobs-t31x.zip (on both ROM for dual boot user) is a must or your device will fail to boot!
As reported by @manup456, graphic glitch occurred in stock ROM with Mali r3p2. Workaround for this issue is "Turn off hardware overlays - Always use GPU for screen compositing" in Settings - Developer but this setting doesn't stick, so you must set it on every boot. Another solution is switch to previous version of NEXT kernel and directly flash Mali r3p1 blobs (on both ROM for dual boot user).

Both version not well tested (i.e. backup and restore not tested since have no free space SD card) but since this version based on official P5100, everything should be work correctly. Flash this at your own risk using existing CWM/TWRP recovery or Heimdall v1.4.0 "sudo heimdall flash --RECOVERY recovery.img" command.
I am almost sure @Phil3759 will officially support our device anytime soon.
ROOT + BLACKHAWK + PHILZ TOUCH FOR YOUR BRAND NEW T31X
Single step for root and PhilZ Touch recovery using Heimdall v1.4.0:
Extract both blackhawk kernel boot.img and PhilZ Touch recovery.img
Install Heimdall for your operating system: Linux, OSX, or Windows
Boot your device into download mode, connect it to your computer, flash:
Code:
heimdall flash --BOOT boot.img --RECOVERY recovery.img
Done!
NOTE: I've deleted PhilZ Touch non SELinux version to avoid confusion, total 618 downloads for all variant!
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 mmcblk0p16 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. BIG FAT WARNING: For stock Samsung ROM, NEXT kernel 1.0 or later requires mali-400-r3p2-01rel3-blobs-t31x.zip!
b) Flash latest Extended PhilZ Touch recovery: http://forum.xda-developers.com/showpost.php?p=51364377&postcount=33
c) Atleast 90% battery left.
d) 3 GB free on internal SD.
e) Some spare time
1) Present sammy, setup aosp as secondary:-
i) Reboot into recovery
ii) Select "Run Aroma Dual Boot Tool" in Advaced Menu, create system.img for CM/CM based ROM and then close it
iii) Reboot into secondary recovery (red on screen navigation buttons)
iv) Flash aosp ROM as 2nd ROM
v) Flash blackhawk's NEXT kernel again
2) Present sammy, setup aosp as primary:-
i) Reboot into recovery
ii) Nandroid backup your current sammy ROM
iii) Select "Run Aroma Dual Boot Tool" in Advaced Menu, create system.img for Samsung stock/stock based ROM and then close it
iv) Reboot into secondary recovery (red on screen navigation buttons)
v) Nandroid restore your sammy ROM as 2nd ROM
vi) Flash blackhawk's NEXT kernel again
vii) Reboot into primary recovery
viii) Flash aosp ROM as 1st ROM
ix) Flash blackhawk's NEXT kernel again
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
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
14. "How to flash newer version of 2nd rom?"
A. Just flash it from secondary recovery. Flash blackhawk's NEXT kernel again
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 recovery - whichever you used to do. Kernel image is copied to the unified kernel partition
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 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
25. "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.
26. "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.
27. "Is there an easier way for dual-boot?"
A. Yes, send your device to me.
28. "DB architecture?"
A. Like you know, every rom has a /data, /system, /cache partition and a kernel to boot.
For primary rom, it's
mmcblk0p21 = /data
mmcblk0p20 = /system
mmcblk0p19 = /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 mmcblk0p16 which is hidden partition and not used otherwise.
- When second rom is booting, second rom data is bind mounted to mmcblk0p21 as /data/
- data/media/.secondrom/system.img partition is mounted as /system.
- mmcblk0p16 is mounted as /cache.
More FAQs will be added and the list will be updated as DB is improved.
Build kernel and kernel modules for Samsung Galaxy Tab 3 8.0 SM-T31x Exynos 4212
Ketut P. Kumajaya <ketut.kumajaya at gmail dot com>, Oct 2013
Samsung Open Source Release Center: http://opensource.samsung.com/reception/receptionSub.do?method=sub&sub=F&searchValue=sm-t31
Samsung OSRC exFAT source: http://opensource.samsung.com/reception/receptionSub.do?method=sub&sub=F&searchValue=exfat
Working kernel source, compilable and tested on SM-T311: https://github.com/kumajaya/android_kernel_samsung_lt01
I assume your home directory is /home/android
Clone kernel source repo:
Code:
$ cd /home/android/
$ git clone git://github.com/kumajaya/android_kernel_samsung_lt01.git
Create an environtment text file, save it as /home/android/build.env (change CROSS_COMPILE to point to your toolchain):
Code:
export CROSS_COMPILE='/opt/toolchains/arm-eabi-4.6/bin/arm-eabi-'
export LDFLAGS=''
export CFLAGS=''
export SUBARCH=arm
export ARCH=arm
Import environtment file above (dot+space+build.env), create build directory outside kernel source directory, and start the building process:
Code:
$ cd /home/android/android_kernel_samsung_lt01
$ . /home/android/build.env
$ mkdir -p /home/android/build/lt01
$ make O=/home/android/build/lt01 mrproper
$ make O=/home/android/build/lt01 tab3_3G8_01_defconfig
$ make -j8 O=/home/android/build/lt01
Copy the resulting kernel and modules to a binary directory:
Code:
$ mkdir -p /home/android/build/lt01-bin
$ cp /home/android/build/lt01/arch/arm/boot/zImage /home/android/build/lt01-bin/
$ find /home/android/build/lt01/ -type f -name *.ko -exec cp {} /home/android/build/lt01-bin/ \;
Your kernel and all kernel modules ready in /home/android/build/lt01-bin/

Supported android version: 13 (Stock ROM)
Kernel base source: https://github.com/engstk/pxl4a
Installation steps
First we need to remove encryption from our phone, pixel 4a is a slot device so we need to flash this in TWRP and format data (Advanced -> format data -> yes)
Next we need to do initial setup, skip pattern lock, install magisk app (magisk is already installed after flashing DSE NEO, but the app is missing) magisk app
Our device have Read-Only filesystem so we need to flash this in TWRP, and use default options
Now we can flash kernel in TWRP
If you want to use latest nethunter terminal app that is based on neoterm instead of crappy nh terminal you need to build terminal and nethunter apps in android studio and install them on your phone
Navigate to nethunter chroot manager now, and install full kalifs
Download firmware files from here, go to root shell and enter
Code:
mount -o rw,remount /
and copy all files inside firmware folder to /vendor/firmware. You can use any root expoler app or copy it using terminal
That's it! You have working nethunter device with all features supported now!
Trying this now
Hi! This kernel only work in stock roms? Can use it in RiceDroid custom rom?

It's based on stock kernel source, so probably it won't work, but you can try it as your ROM kernel source can be based on stock source too

Working great! Thank you
It works like a charm thank you! I've been banging my head against the wall trying to get external adapters working for what seems like forever and it's finally happened
Thank you for your hard work and well done!
Can you also include Ralink mt7601u (TL-WN727N)

Hi, if this chipset is supported by Kali nethunter patches, then it should work, but if it's not I can't do it. If you really want to get this chipset working you can try to manually add driver support and build kernel with it for yourself
