Information: Samsung Galaxy S II ("i9100")
The install guide assumes your device is running stock Android 4.x.
This device was previously called galaxys2. Current development uses the i9100 name, but older releases of CyanogenMod can still be downloaded from download.cyanogenmod.org/?device=galaxys2.
Some second-generation Samsung Exynos devices are potentially susceptible to a "superbrick" caused by performing a factory reset with the stock kernel, which effectively kills the internal memory in the device. It is highly recommended you do not perform this operation while using a stock kernel for safety reasons. To make sure you aren't running the stock kernel (only needed when coming from the stock ROM), fully install CM without performing a factory reset and reboot to recovery before you perform the factory reset.
If you used a non-official method to remove a provider lock, your /efs partition may become corrupt! It is highly recommended you make a backup of this for safe keeping before attempting to modify your device, especially if you plan to remove such a lock.
The newest CM11 Gapps package (20140606) is too big for the /system partition of i9100. Please use the 20140105 package instead.
