Hey people, i need help badly, have a nice brick sitting here, Iphone 4 GSM model was running ios 6.1 jailbroken with evasi0n, and everything was going smoothly, until it just black screened on me, out of nowhere, now i cant see anything, i can access both DFU an pwn'd DFU but i cant restore FW, i just get an 16xx error, tried just restoring an updating to 6.1.3 but i get the same errors, tried multiple custom FW's an cant get past the 16xx the phone just sticks at 'Preparing iphone for restore' in itunes. Using redsn0ws method, it hangs on uploading first stage, the phone disconnects and should restart to allow the upload to finish but it doesnt :/

Any help is appreciated....

Thanks
