Hi there Donnad14,

If you're still unable to restore your iPhone because of this error 4013, then I would recommend you use the troubleshooting in the following article about that error code:

Try these steps to resolve the issue:

2. Restart your computer.
3. Make sure your computer is up to date. If an update requires a restart, check for updates again after you restart.

   • Learn more about updating Windows.
4. Restore using another USB cable.
5. Restore your device on another computer.

If you continue to see error 4005, 4013, or 4014 when you restore your device, contact Apple for support.
