As I understand correctly you are unable to restore your phone due to an unknown error message that you are getting from iTunes. I would start wiht the troubleshooting in this article here:
Resolve iOS update and restore errors in iTunes
If the issue persists, I would next use the troubleshooting in this article if you are getting a specific error number:

Thank you for using Apple Support Communities.
All the very best,

Get help with iOS update and restore errors
If the USB connection between your device and computer is interrupted, you might not be able to update or restore.
To narrow down the issue, you can try different equipment:
- Use the USB cable that came with your device, or a different Apple USB cable.
- Plug your cable into a different USB port directly on your computer. Don't plug it into your keyboard.
- Try a different computer.
- Solve other issues with the USB connection, then with your security software.
If you still see the error message, check for hardware issues by following the next section.
Check for hardware issues
Related errors: 1, 3, 11, 12, 13, 14, 16, 20, 21, 23, 26, 27, 28, 29, 34, 35, 36, 37, 40, 1002, 1004, 1011, 1012, 1014, 1667, or 1669.
These errors mean that your device or computer might have a hardware issue that stops the update or restore from completing.
- Check that your security software and settings aren't blocking your device from communicating with the Apple update server.
- Then try to restore your iOS device two more times while connected with a cable, computer, and network you know are good.
- Make sure that 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.
