CyanogenMod is a free, community built distribution of Android 2.3.5 (Gingerbread) which greatly extends the capabilities of your phone.
Warning : Not for new users, flash this build only if you know what you are doing !!!
Latest version: http://download.cyanogenmod.com/?device=galaxys2
Check the md5sum if you want to be sure that the download worked (different OSes have different programs that do md5, on ubuntu it is md5sum that you run against the zip you download and compare to the md5sum number shown on the download website). ROMManager does this automatically for ROMs you download via ROMManager.
INSTRUCTIONS:
:::: First time flashing CM 7 to your Galaxy S2 (or coming from another ROM)?
Easy way:
Harder way:
:::: Upgrading from earlier CM7?
ROM Manager method:
Clockwork Mod method:
There are no Google Apps bundled with CM ROMs, because Google asked Cyanogen to remove copyrighted apps. After flashing the rom, don't forget to flash Google Addon package if you want it. ROM Manager will allow you to flash it if you just go into it and after flashing the ClockworkMod recovery for Samsung Galaxy S2, choose Download ROMs, and pick Google Apps. Or download and push the gapps zip for CM7 from http://wiki.cyanogenmod.com/index.php?title=Latest_Version#Google_Apps to the sdcard and flash it via ClockworkMod recovery.
:::: Going to another ROM from CM7?
You can go back and forth freely between CM7 and other ROMs via ROM Manager or ClockworkMod recovery as the file systems are the same and nandroid backup/restore works to go between ROMs.
Please visit the CyanogenMod Wiki for step-by-step installation walkthroughs and tons of other useful information.
