[Galaxy S III Android Development] maxniper:
Hi all,

This the UNOFICIAL thread of Boeffla-Kernel for the Samsung Galaxy S3 international.

This change to the original kernel of Lord Boeffla because i like the kernel and to be possible that guys like me that are stuck to EFS_V1 and can't upgrade to V2 to use New Samsung based Jelly Bean 4.3.x and enjoy this really great Kernel

Notes:

This Kernel was changed to work with old Modem EFS_V1 on new Samsung based Jelly Bean 4.3.x roms!!!

This Kernel is only for the new Samsung based Jelly Bean 4.3.x roms!!!

*** 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
