If Flashing From a Official ROM like the AT&T ICS

If you coming from a Custom Rom (ie CM10.1/AOKP/Embryo) it's best practice to Wipe Data/Factory Reset, Wipe Cache, Wipe Dalvik Cache to avoid bootloop

2. Hold down Power and Both Volume Buttons to get into the stock recovery that was flashed with the Rom

3. Wipe Data/Factory Reset 3 Times, Wipe Cache 3 Times, and Wipe Dalvik Cache 3 Times and Reboot and it will work, it takes the Rom about 5-10 Mins to Settle after being installed so be patient.
