Fixing error 20 during iPhone restoration using iTunes

* Causes of error 20 during iPhone restoration via iTunes

- Error 20 is caused by either faulty charging sockets or software glitches.

+ Hardware-related issue with charging socket: This error may not necessarily result from a damaged charging socket; sometimes it's just loose, disconnected, or experiencing weak signals. It's highly likely that the charging socket is malfunctioning. During iPhone restoration, iTunes encounters obstacles related to this and reports this error.
