Hi all,

this is the thread about the well-known Boeffla-Kernel for the Samsung Galaxy S3 international.

Notes:

Never install it on CM or AOSP based roms!!!

History

Basically I created Boeffla-Kernel as there was no kernel for the Samsung Galaxy S3 around that had exactly the mix of functionalities that I wanted. I wanted to have full flexibility in undervolting and charge rates for instance, but did not like the sharpness and/or brightness tweaks many kernels have implemented as per default.

Hence, I began to create my own kernel after a while, adding all the features I like. This is the result of my work, which in the end I decided to share with you. I hope you like it as much as I do.

The objective of this kernel is to have a kernel for daily use. It does not aim for best battery life, or best smoothness or best benchmark scores. It aims more for a good mix of all, not sacrificing stability and functionality in the end.
And - most important: It aims to stay quite close to stock !!!

This said, I will definitely NEVER implement:
  • dual boot (I do not need it)
  • color "calibration" (I do not like it, but I like the crispy stock colours)
  • real hard overclocking higher than 1600 MHz as this is outside of Exynos specs
  • f2fs - it is known to cause various issues and compatibility problems
  • anything that requires upstreaming of kernel parts to a higher kernel major version
So do not even ask for it. Everything else I am happy to check and decide.

Compatibility

To reiterate it again: This kernel is only for Samsung based Jelly Bean (Android 4.1.x) firmwares. It is not designed to run on AOSP based roms!


Configuration of the kernel

To tweak and configure the kernel, manually load and install the app "Boeffla-Config V2" from here: DOWNLOAD

You will receive a personal donation code which unlocks some nice comfort functions in Boeffla-Config V2 on top.


Source code

All sources can be found in my Github repository: http://github.com/andip71


Credits to developers

Of course, I had never been able to create all that by my own. So I want to give credits to the really good developers around, that have given me all the inspiration and from which I cherry picked lots of the implemented functionalities:

* Yank555
* ZaneZam
* Hardcore
* Chainfire
* Harunjo
* AndreiLux
* Netarchy
* Gokhanmoral
* Simone201
* Supercurio
* Mialwe
* Entropy512
* Faux

... I just hope I did not forget someone. If so, please let me know and I will add you of course.
Thanks to all of you for your great work !!!

Disclaimer

*** As always - Flash on our own risk! ***

Make sure you flash the correct version depending on your firmware version!

I can and will not take any responsibility for bricked phones or lost data.

It is generally recommended to run a complete Nandroid backup in CWM recovery and safely store your personal data before you flash a new kernel.


Cheers and enjoy
Andi

Downloaded via PC. 5 min on it and I love it. Keyboard seems faster than before. Cleaned RAM twice, no redraw. Maybe launcher is locked in memory?

Here's your beer. Cheers and best of luck!
