Notes

Note:

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

Note:

This device was previously called galaxys2att. Current development uses the i777 name, but older releases of CyanogenMod can still be downloaded from download.cyanogenmod.org/?device=galaxys2att.

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.
