Notes

Note:

The install guide assumes your device is running stock Android 4.x.

Note:

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.

WARNING:

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.

WARNING:

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.

WARNING:

The newest CM11 Gapps package (20140606) is too big for the /system partition of i9100. Please use the 20140105 package instead.
