iPhone 12 crashes and restarts every time I try and unlock it
I cannot access my phone without it crashing and restarting to loading screen. When I enter recovery mode, iTunes does not show my phone. My phone will not enter DFU
Does it also persist when you do a forced restart without it plugged into a computer?
First take off any case. Then:
Press and very quickly release the volume up button. > Immediately press and very quickly release by the volume down button > Immediately press and hold down the side button and keep holding the side button until the Apple logo appears, release the side button.
