My little cousin has an xbox 360 and originally my family let one of the family friends who was good with computers help with it but after some events accord they stopped talking to him and he is supposedly the one who set the button combination lock on the system for settings -> family and now we cant remove the limit for the time to play the system, is there anyway to bypass the lock, we dont know the code, he says he doesnt and the recovery answer he gave us doesnt work
