[Galaxy S 5 Android Development (Snapdragon)] AndroidGX:
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 [MENTION=3194769]xdamc2010[/MENTION] 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. Huge kudos to him, and also to [MENTION=6187506]JDizzle80[/MENTION] to find the solution at the same time.

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.
