I followed these instructions for windows (the one where backup was made on iOS beta and changed the Product Version to 16.6 from 17.0) but it did not work. It still kept saying that it could not be restored because an error occurred.

A few devices can be restored this way, but some cannot. This method is to trick Apple’s authentication system and it’s possible they have patched it. So I always encourage people to back up their devices before updating to any betas.

IMPORTANT: on windows its the shift key. WICHTIG: unter Windows ist des die Umschalt-Taste

hold the shift key
