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