when trying to go to 2.0. I tried to winpwn 1.1.4 cause I couldn't get DFU to work. And it failed so now my ipod won't turn on or go into recovery mode. But when I try DFU mode it flashes a white screen and if during that time I double click a ipsw it starts a restore. It goes to the normal apple boot screen with a SWOD on the bottom then crashes to an error 1601. So what can I do to fix it?
