Error 40: This error may indicate a hardware issue with your device, but it is typically caused by out-of-date or incorrectly configured security software. Follow the steps in this article. Also attempt to restore while connected with a known-good 30-pin Dock Connector cable, computer, and network to isolate this issue to the device. The MAC address being missing or the IMEI being the default value, (00 499901 064000 0), can also confirm a hardware issue.
