@AnnaAnthro Apple should be able to unlock the device they forcibly locked.

And prevent future updates that break secure passwords like this. 😡

@EdwinG @AnnaAnthro Unfortunately, I think that this person might not be able to get their data back. As far as I remember, the device passcode has to be entered before any OS update/downgrade, and I don't think it's even possible to downgrade iOS versions anymore. Maybe a physical keyboard connected to the phone, but I think iPhones block any USB devices when in BFU, and even then, switching they physical keyboard layout might not be possible from the BFU lock screen.

@prusa @AnnaAnthro IIRC, the phone’s paired computer should be able to update their iPhone to a fixed iOS version (e.g.: iOS 42.23.4)
