Try to restore your iOS device two more times while connected with a cable, computer, and network you know are good. Also, confirm your security software and settings are allowing communication between your device and update servers. If you still see the error message when you update or restore, contact Apple support.
Error 1015 might happen after making unauthorized modifications to iOS, also called "jailbreaking."
Have a nice day,
