[Samsung Galaxy W I8150] Keff91:
Skull Kernel

Build with Linaro GCC 4.8.2 Toolchain

Only for JellyBean 4.2.2

This kernel is based on arco source. It included extra tweaks and tuning for better performance

or battery life!

:fingers-crossed:

Some warning to all users before flashing away!

Please do not install this kernel on Android version other than 4.2.2

By flashing this kernel, you are accepting any results that might happen with this kernel

I'm not responsible for any damage and your warrantly might be void!

(damage seldom happen as I always get this kernel tested and ONLY release when it come stable)

​

NOTE !!

Install this kernel will replace the modules at system/lib/modules and will back up your original modules to system/lib/modules.bak.

Please note that you only need to restore modules if you switch to other kernel (not skull kernel), otherwise forget about it :)
