Are you trying to restore the iDevice without losing the data?

Did you tried to restore via DFU Mode...?

hello Chand963 and all,

no, 20'th % is Nand access process. If stuck on it you have (probably) hardware issue (Nand power/data short circuit or internal Nand problem).

You can directly contact the staff to seek suggestions. Or you can use related iOS system repair tools such as TunesKit iOS System Recovery to fix your issue.

This is mostly NAND issue, but 1st try restore different ways. with i tunes you got error 4013, this will be 99% NAND problem. contact service.

I had a friend who had a similar problem and I advised him to try fixing iOS. I also recommend you try LazePaw iOS System Recovery.

There is a good and effective good called Joyoshare UltFix you can try. My friend once used it to successfully fix the issue.

Cleaning out your charge port or removing your SIM card can be the solution you’re looking for
