I got my iPhone stolen and I'm guessing he tried to do a factory reset, but I know jailbreak does something differently with that but it's stuck in a bootloop and I've tried just about everything I can do with iTunes and putting the phone in different modes.
Power + home for 10 sec then just home = Apple update logo then crashes and goes back to boot loop.
Power and + volume = nothing
