I just triggered an OTA update from Beta 1 to Beta 2 and it unfortunately goes into a loop. The progress bar stays stuck at the beginning, then the phone seems to reboot and retry to the same results. Hard reset, DFU, ... nothing will actually bring back the phone, it keeps entering the update and the never ending loop. That's the first time of my life I wish I could remove my iPhone battery (without an engineering degree I mean). Anyone with an idea on what to try next that is not about buying a new phone ?
