iPhone 14 Upgrade Issue and Resolution

A summary of the experience with upgrading an iPhone 14 to iOS 17.5 and how I fixed the problem.


  • I had an iPhone 14 with insufficient storage to upgrade to iOS 17.5.
  • I used a MacBook Air to download the update and transfer it to the phone.
  • The phone entered an endless loop of trying to boot up and finalize the update.
  • I tried to reset the phone by pressing the up button, down button, and power button for over 5 seconds, but it did not work.
  • I called customer support, but they only suggested the same reset method.


  • I plugged the phone into the MacBook Air and saw the option to enter recovery mode on the phone.
  • I chose to update the phone again, but it failed and entered the same loop.
  • I entered recovery mode again and chose to restore the phone instead.
  • The phone was upgraded to iOS 17.5 and restored from a backup that was saved on the MacBook Air before the update.
  • The whole process took about two hours, but I was able to use the phone with the latest iOS release.
