Hi there, my friend gave me his jailbroken password locked iPhone 4 (he forgot his password and asked me to restore it), but when ever I tried to restore it, I always get tons of different errors. At first I attempted to restore it, and got error 3149, I decided to use tiny umbrella to counter this and when I did, I got error 1600. Obviously, since it's locked I had to put it in DFU mode because I can't restore it with a passcode enabled. I tried to put it in pwned DFU mode, switched computers, switched cables, but I keep getting the same errors. I do not know why it's doing it and I am not sure what version it is currently on. I am just trying to get the phone to 6.1 which is the newest version but iTunes is not letting me. Does anyone have any idea why it's doing it?
