Hey guys so if you are getting error 6 in iTunes then you need to use macOS High Sierra for this to work, but the latest security updates and the new version of iTunes is what causes error 6, so to fix it you need to do a fresh reinstall of macOS High Sierra this will remove the security updates for macOS High Sierra and iTunes 12.8 that prevents this from working and you need iTunes 12.7 for this to work as well

Even if I press exit recovery mode on error 1013, it returns to recovery mode again.

[@iOSPro]

To fix it you need to do the restore 2 times then it will exit recovery mode

[@merusi_boccu]

Should I change and restore it again with pwned dfu?

[@iOSPro]

Yes you need to put it in pwndfu mode and restore it again with the iOS 2.0 iPSW
