Download and install - update CyanogenMod 10 Jellybean 4.1.1 Firmware for Samsung Galaxy S2 GT I9100G (preview)

 

THIS IS JUST A PREVIEW OF THE UPCOMING CM10! IT'S UNFINISHED AND HAS SOME FUNNY AUDIO BUGS!

 First time installing CyanogenMod 10 to your Galaxy S II, or coming from another ROM:
- Make sure you're running ICS bootloaders! (if you're unsure, flash a official ICS rom and proceed)
- Make sure you're running a proper working ClockworkMod-Recovery
- Copy GApps and CM10 ZIPs to your internal SDCard
- Boot into Recovery
- Flash CM10 zip from internal SDCard
- Flash GApps zip from internal SDCard
- DO A DATA WIPE / FACTORY RESET (otherwise your device will be stuck at boot)
- Reboot
- Don't restore Apps using Titanium Backup!

Upgrading from earlier version of CyanogenMod 10:
- Copy CM10 ZIP to your internal SDCard
- Boot into Recovery
- Flash CM10 zip from internal SDCard
- Reboot
