[Galaxy S II Android Development] aniket.lamba:
Welcome to EOS! The EOS project originated with the AOSP release of ICS, and was originally founded by Solarnz and co founded by Bigrushdog. Since then, EOS has evolved into a multinational collaborative effort backed by top Android developers. Our objective is to provide a world class AOSP build with unique features and enhancements.

Team EOS Galaxy SII i9100 [R4]

Because this is an AOSP based ROM, Google Apps are not included. Flash the gapps of your choosing after you flash the ROM. If you need help finding a gapps package, ask any of us and we'll be happy to help

If you're coming from any ROM other than the latest CM 12.1 nightly, flash that first, for all the proprietary firmware to be updated.

These builds are designed to be installed from your favorite recovery. MAKE SURE YOU HAVE THE LATEST 5.1.X COMPATIBLE RECOVERY.

Detailed instructions

:

Going to EOS 5.1.X from another ROM:

Boot to recovery

BACKUP YOUR CURRENT SETUP!!!

Make a full wipe (Dalvik, Dalvik Cache, System, Data)

Flash the ROM

Flash optional kernel if you choose to not use provided kernel **We DO NOT support outside kernels**

Flash gapps

Reboot

Updating from an older EOS build to new EOS build:

You can usually skip the full wipe step and just wipe both caches. If ever you encounter an issue make sure you make a full wipe first before reporting it. This is what most call "Dirty Flashing". Normally this doesn't cause problems, but keep in mind a clean flash is always the best way to go.
