Downgrading from IOS18.4 public beta to the latest non-beta IOS version

Sorry, no. You cannot restore from a higher version of iOS to a lower version.

sorry but that is incorrect. you can always restore to a previous version by doing a factory reset and restoring to a previous version. you will need to connect your phone to your mac. you will need to enter recovery mode in your phone once by pressings the up volume and release, press down volume and release and finally press and hold power button until you see the recovery mode and then from your mac do a restore.

You are the one who is incorrect.

They are asking how to restore a backup from a higher version, not how to restore the iOS version.

And that only works with beta versions, you cannot downgrade from a higher version of a production iOS to a lower version.

You cannot restore data from a higher version of the operating system.

False. You can ONLY downgrade from a beta version to the current shipping release. You cn not downgrade a released version to a lower released version.

No you are incorrect, I literally just did this restore from 18.4 to 18.3 on my phone with my Mac.
