Iphone 6 Error 53

Dear WP Fellows,

My Apple Iphone 6 was stuck at 'error 53' on updating via Itunes.

Google search suggest that its an Touch ID problem and no solution in Pakistan as of today :(

Note:- touch id/thumb was repaired once in the past (abroad), and after repair it was working fine until new update.

Any one knows iphone cheeetaah, who can tackle this problem?
