Kernels

NOTE: The last Apolo kernel working on lollipop 5.1 roms was Apolo 8.0 Beta 9. Development was stopped on Apolo kernel. Gustavo Kernel has not been updated for a while, so it doesn't support lollipop 5.1. DorimanX and gustavo kernel has been updated by Lysergic Acid and myself to support latest CM12.1 ROMs, but lack support of other ROMs currently.

NOTE: If you don't want to face any bugs, please stay on the in-built kernel included in your ROM.

1. [KERNEL] APOLO [i9100][SAMMY & AOSP] - APOLO 8.0 Beta 8 is highly recommended since it doesn't suffer random reboots.

2. [KERNEL][UNOFFICIAL][UBER]DorimanX LP 5.X.X - Will only work on CM12.1 Based roms

NOTE: If you haven't re-partitioned your phone yet, you will needed to use a minimal or mini gapps otherwise you will get errors while flashing!

Can't Decide? Here's what I recommend.

1. TK Gapps - You must select pico version
