Hello, So I upgrade my iPhone 3g to 4.2.1 and jailbreak it with redsn0w and I activate the iPad Baseband so I can unlock it !! , All was good , so I decide that I want it to restore it to the same ipsw(4.2.1) (to erase some stuff ) ( I know a dumb idea, but I already did) So the Problem is that iTunes won't let me restore it ( I keep getting error 1015 , I run Tinny Umbrella , reboot ) ... Any help ?? PS: I downgrade it to 4.1 and it works great , but when I point the 4.2.1(ipsw) keep throwing me to Recovery Mode Thanks Any help would be appreciate it !!
