History

Basically I created the Samsung version of 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 !!! Which in fact for the CM kernel means now... close to CM kernel sources.

Compatibility

To reiterate it again: This kernel is only for CM10.1 and CM10.2 based firmwares. It is not designed to run on Samsung based roms!


Configuration of the kernel

All configuration needs to be done ideally by the app "Boeffla-Config", which you can get from Google playstore or on androidpit.com.


Donation

If you like my work, fee free to donate via XDA developers: Donation-Link

Or, just purchase the donation version of the Boeffla-Config app, which also gives you some extra features.


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

ÄNTLIGEN så finns denna till AOSP-baserade ROM'ar.

Hans ljudprofiler/mods är helt magiska och det är grymt att få de på AOSP nu!

Inget mer pillande med DSP Manager tack och lov.

 

Drog in den för några dagar sedan.. Ännu roligare batteritid
Härligaste combon är möjlig igen.. Temaseks 10.2 + Boeffla som kärna..

 

Funkar allting med denna ? Läste på xda att någons wifi inte kickat igång efter flashning?

 

Inga problem här
