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!

Question: Were you using a computer to update your iPhone? A poor connection between the iPhone and the computer may cause this behavior.


Did you get the iPhone updated finally? If NOT then I recommend that following steps without the use of a computer but while the iPhone is connected to a Wi-Fi Network.


Make sure that your iPhone is setup to meet the following requirements before you attempt to update the iOS version over a Wi-Fi Network. Open Settings ➡️ General ➡️ Software Update: If there is an update available for your iPhone then it will be listed here. Follow the on-screen instructions to download and update your iPhone. 

  • Your iPhone must have a fast Wi-Fi connection or a 5G cellular connection. You cannot update over a cellular hotspot
  • The iPhone can not be in Low Power mode
  • The battery state of charge must be above 50%
  • Your iPhone must have at least 10GB or more free storage space
  • Your iPhone cannot be connected through VPN
  • You should leave the phone plugged in until it finishes updating, both to assure that it remains above 50% and to keep Wi-Fi enabled (Wi-Fi turns off when the phone sleeps if not connected to power).
