[Galaxy Note 10.1 Android Development] andip71:
*** NOTE: All kernels are now officially end-of-life (EOL).

Please do not expect any more updates for them in future, no maintenance and no bugfixing. ***

Hi all,

this is the thread about my Boeffla-Kernel for the Galaxy Note 10.1 n80xx.

Some of you might know my kernel already from the Galaxy S3 area.

If you want to learn more about the kernel, it's features and how to configure what, I would recommend you to visit the Galaxy S3 thread of the kernel.

Compatibility

Important: This kernel is only meant to be compatible with official Samsung stock firmware and nothing else.

So when the kernel does not run on custom rom XYZ, do not even bother me with it or ask hundred times in the thread for compatibility.

I could not care less about it !!

Notes:

From version 2.2 onwards, this kernel should work on the following devices: n8000, n8010 and n8013

This kernel is only for Samsung based Jelly Bean (Android 4.1.x) roms!!! Do not install it on CM or AOSP based roms!!!

If you have questions to settings, presets, others configuration and wanna share your configuration, head over to the unofficial Boeffla-Config App Config sharing thread:

Support

First read the FAQ section on the Homepage !!!

I will refuse to give support if you do any undervolting and experience freezes or hot reboots.

Objective

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 !!!

I will, also in future, only add features that make sense to me personally as well and are not against my initial objectives. You can always raise your wishes and requests, however there is absolutely no guarantee it will be implemented.

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 the downloads section on www.boeffla.de.

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:

... 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 !!!

*** 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
