IPhone error 1604?

Hey guys, I tried to downgrade my iPhone 3G from 3.1.3 to 3.1.2 firmware and doing so I received an error message Error 1604 and iTunes connected to the frozen image. I tried to restore factory settings, but I can not let him make and gives an error message 13. Please help me. Thanks in advance.
