iPhone 7 error -1 ?

I don't know what do you want to do? The meaning of iPhone 7 error-1? I remember Rewa released a  iPhone Error Codes Mean, it explained the "Errors: 1, 3, 10, 11, 12, 13, 14, 16, 20, 21, 23, 26, 27, 28, 29, 34, 35, 36, 37, 40, 1000, 1002, 1004, 1011, 1012, 1014, 1667, or 1669", this is a hardware issues, sometimes unknown hardware errors concerning either the iPhone or the computer can interfere with the connection between the two of them.
