WARNING :

This KERNEL is only for Galaxy S5 Plus LTE-A (SM-G901F/kccat6) version !

You will void your warranty after flashing this ROM (knox @ 0x1)
I'am not responsible of any damage caused to your device after flashing this KERNEL

Some reading..

First of all, I would like to thanks a lot my friend @xdamc2010 for his hard investment about making a kernel finally bootable and stable kernel for our G901F and tells me his solution to finally make this kernel living.
SimpleGX is only looking for simplicity and stability, trying to aim for best battery life, smoothness and performance experience, than a pure stock kernel.
I still don’t qualify myself as of a real developer, but just a basic person with some android/linux knowledge already.
As always, I’m enjoying sharing my contribution here on XDA for free, which taking me a lot of time to release, so if you can offer me a little beer, I will really appreciate that.



This kernel must be only flashed over an official Samsung ROM and not AOSP/AOKP !

Feel free to include my kernel to your ROMs / Threads but please don't forget to inform/ask first via PM and credit me in your original thread.

★ WHAT TO EXPECT ★ :
6430991398474794tickcircle.png
(over a pure stock kernel) :
  • Best battery life experience.
  • Much better overall performance.
  • Efficient (only proven to be good ones and not affecting battery life) tweaks.
  • Stay as close as possible from stock source.



★ FEATURES (up-to-date) ★ :
6430991398474794tickcircle.png
Base :
  • Directly based on "SM-G901F_EUR_LL_Opensource.zip" (XXU1BOE2) Lollipop Android 5.0.2 source from Samsung (for clean work and stability)
  • Compiled with Linaro Cross Compiler (4.9.4 / 2015.06) toolchain (optimized for Cortex-A15) with optimization flags.
  • Ramdisk from XXU1BOH4
6430991398474794tickcircle.png
Main :
  • ZZMoove (v1.0 beta8) governor added
  • ZRAM enabled with LZ4 compression and set as default
  • TCP congestion control modules activated: Westwood (currently as default), reno, bic, cubic and htcp
  • SElinux set to "Permissive"
  • init.d support
  • DriveDroid support
6430991398474794tickcircle.png
Various tweaks :
  • Android logger disabled
  • Kernel logger disabled
  • CRC disabled
  • Doubled min-max ReadAhead
  • slub.c: little tweak for performance improvements
  • Set initial TCP window size to 64K
  • Removes the red message "KERNEL IS NOT SEANDROID ENFORCING" during boot stage
  • Samsung Root restriction disabled

Features that will NEVER be included in this kernel :

  • auto-root.
  • LED control.
  • Charge control.
  • Master sequence (screen calibrated).
  • ABB (Adaptive Body Bias).
  • Any upgrade of Linux kernel 3.1x
  • Dual-Boot Sammy/AOSP.
  • CyanogenMod compatibility.
  • MIUI compatibility.
  • etc.




★ PREREQUISITE ★ :
  • Your device must be on Lollipop Samsung firmware.
  • A custom recovery (CWM recommanded) to flash the kernel.



★ SOURCE (up-to-date) ★ :



★ INSTALLATION PROCEDURES ★ :
- You freshly bought your new Galaxy S5 Plus device and want to install this kernel ? follow this :
  1. Backup everything you need (internal & external),
  2. Reboot in Download mode,
  3. Flash Chenglu's unofficial custom CWM based recovery via Odin (load as AP),
  4. Reboot to your new CWM recovery,
  5. Flash the KERNEL,
  6. Reboot and enjoy !
- You already is on SimpleGX ROM ? follow this :
  1. Reboot to your CWM recovery,
  2. Flash the KERNEL,
  3. Reboot and enjoy !
- If you want to update your current SimpleGX KERNEL :
  1. Backup everything you need (internal & external).
  2. Reboot to your CWM recovery,
  3. Flash the KERNEL,
  4. Reboot and enjoy !
- Want to switch back to stock KERNEL ? :
  1. Grab your matched firmware HERE,
  2. Reboot to your CWM recovery,
  3. Flash the KERNEL,
  4. Reboot and enjoy !

As precised into first post, this kind of feature won't be included so far because I lik stock colors, and also because I don't have the talent to do this kind of stuff :D

It is planned but I need some friend help to do this, nothing hurry yet, so it will take some weeks/months before I include OC, I guess.

i will solve this problem lol :) (9NW20816U1247801P)
nb/ ''Removes message "KERNEL IS NOT SEANDROID ENFORCING" during boot'' how did u do ? ^^

Thanks for the great work :)

Thanks mate, appreciated! welcome to post #4 :good::cowboy:
About the tips hiding SEANDROID message in red, I prefer to keep it secret for the moment (I respect xdamc2010), as it's experimental and I'am currently having some issues, but maybe later then ;)
cheers'

N-JoY! :good:

Note : It seems you are no more obliged to flash matching firmware ramdisk to get the kernel booting, so for exemple you can flash back a v1.0.1 (featuring BOC4 ramdisk) into BOD6 firmware without any problem :good: I go edit first post about this.
