iPhone continuously asking for passcode after requesting 17.2.1 update
I encountered an issue today and found a solution that I'd like to share.
After a request for update was submitted, my wife's iPhone 14 Pro Max was repeatedly opening and closing the passcode entry screen. When any passcode (correct or incorrect) was entered, the screen would close, showing the desktop, and then open again. We were unable to restart the phone while this was occurring.
I was able to interrupt this behavior by quickly swiping down from the top edge of the screen to open the Control Center when the passcode entry screen momentarily closed. This seemed to halt the loop, but I restarted the phone just to be sure. I hope this helps someone else!
