Bumping this I have an unrestorable device thanks to this issue (iPad Air 5, iOS 26b4)

[CrusherNotDrip]

I am also currently experiencing this problem. (iPhone 11 Pro Max, iOS 26b3 and now attempting to get out of restore mode by either reupdating to 26b3 or above so I don't lose my data as I have no backups :[ )
