Q: error 14 shows when updating iphone

Hello, PoppyBob.  

Thank you for visiting Apple Support Communities.  

I understand that you are receiving an error 14 when attempting to update your iPhone.  This error is usually related to a USB issue.  Here are the troubleshooting steps that I would recommend for this specific error.  

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.
