Hi Elly,
Thanks for following up with the additional information.
Based on error 14, try using a different USB port and cable, as outlined in the following article: iOS update and restore errors - Apple Support
If you see one of the errors below, check your USB connection, USB cable, USB port, or computer:
- 13, 14, 1600, 1601, 1602, 1603, 1604, 1611, 1643–1650 . . .
Here's what to check. Try again after each step:
- Use the USB cable that came with your device. If you don't have it, try a different Apple USB cable.
- Switch to a different USB port on your computer. Don't plug into your keyboard.
