Oct 1, 2015 11:33 PM in response to ellierose2002by Ingo2711,If you are getting this error during updating your iOS, make sure that your security software is not blocking the contact to Apple servers while the software is being installed onto your device.
Another reason could be the USB connection. Make sure to plug into the USB port directly, not into an USB hub. Also use a fast USB port on your computer.
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.
If you still see the error message, check for outdated or modified software.
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, 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.
