Hi, azoozar!

Thanks for using the Apple Support Communities. From your post, I understand that you are unable to update your iPhone and that iTunes is returning an error message of -1. I'd be happy to help!

My recommendation is to follow the "Check your hardware" section of this article Get help with iOS update and restore errors , which states:

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, 10, 11, 12, 13, 14, 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:

If iTunes is already open, quit and reopen it.

Check your third-party security software.

Make sure that your USB cable, computer, and network are reliable. Then try twice more to restore your iOS device.

Check for outdated or modified software.

If you still see the error, contact Apple Support.

Have a great day!

As a followup to the post from Community Specialist Chris_g1, -1 and 1 are the same error code.

Also note that the latest version of iTunes is 12.6. It requires Mac OS 10.9.5 or later, or Windows 7 or later. So make sure your version really is 12.6 or later.
