My iPhone 5 would not restore or re boot when connected to usb iTunes it showed the apple logo then the connection symbol only. When I try to restore or update, the responds I receive is 'unknown error (2001). How can I fix this?

Hi there Viikandy,

It sounds like your phone is not restoring due to an unknown error when you connect it to your computer. I would first use the troubleshooting in the following article to help you troubleshoot that:

Resolve iOS update and restore errors in iTunes

If the issue persists, there is more specific troubleshooting for that exact error number in the following article:

Get help with iOS update and restore errors

Check your USB connections

Errors: 13, 14, 1600, 1601, 1602, 1603, 1604, 1611, 1643-1650, 2000, 2001, 2002, 2005, 2006, 2009, 4005, 4013, 4014. You might also see a message that includes "invalid response."

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.
