Part 1: Different iTunes Error Happened During Restoring or Updating Your iDevice.

You may have encountered different errors during restoring and updating your device. You may have seen “This device cannot be restored Error XXX” message from iTunes before and wondering what just happened. A common error usually exists because of just simple things. And so there are things you need to consider first when you’re updating or restoring your iDevice. Here are some of those:

  • Stable Internet Connection.

    Updating and restoring take time before it is completed, so a strong internet connection is needed. If ever you have been disconnected or the internet starts slowing down during the process there is a great chance that you will encounter an iTunes error. Better yet do a speed test before and make sure your Wi-Fi router works properly.
  • Firmware Issue.

    Make sure you have the right firmware for your device or else, it is guaranteed you’ll encounter the error.
  • Security software.

    Sometimes, you need to disable first your anti-virus and firewall to stop them from blocking the authentication. Is it because there is a misunderstanding between your hard drive and the security software? This issue mostly causes iTunes error 2, iTunes error 4, iTunes error 6, iTunes error 9 and etc. So check first your firewall setting to ensure that iTunes was not being blocked.
  • USB cable and port issue.

    iPhone devices are very sensitive when it comes to USB cables, so it is preferred that you use an Apple original USB cable. Also, when connecting your device to the computer make sure to connect it directly without any third party or any accessories.
