Error -1 is most often an error of the baseband chip. It fails at initialization during the Restore process. It is a fatal error, meaning no fix. That said, try all sorts of Restore attempts of your iPhone to get past this step. Try different computers, try custom firmwares, try jailbreak tools. Nothing will work, but try anyway.
