Information: Samsung Galaxy S II (AT&T) ("i777")
The install guide assumes your device is running stock Android 4.x.
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.
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.
