Did you use the AIO to root your phone?
if so, you should have ClockworkMod Recovery.
Power off your device,and press Power+R at the same time to enter recovery.
yes, that's the R key on the keyboard, btw.
you may stop holding the power key when you see the Samsung logo, but keep pressing R until you're in the recovery menu.
If I've helped you, please do hit the Thanks button.
And remember to pay it forward!
Or if you REALLY insist, there's always PayPal
