I forgot my unlock code on my ipad, I try to restore and get an error code (10). Is there another way to completely restore my ipad?

Check your hardware

If you see error 53, use these steps.

If you see one of the errors below, you might have a hardware issue:

• 1, 3, 11, 12, 13, 16
• 20, 21, 23, 26, 27, 28, 29, 34, 35, 36, 37, 40, 56
• 1002, 1004, 1011, 1012, 1014, 1667, 1669

Here's what to check. Try again after each step:

1. If iTunes is already open, quit and reopen it.
2. Check your third-party security software.
3. Make sure that your USB cable, computer, and network are reliable. Then try twice more to restore your device.
4. Check for outdated or modified software.
