iPhone 15 Pro update to iOS 17.1.1 failing / can't setup from old phone on iOS 17.1.2

Hi


I just bought a new iphone 15 Pro which came pre-installed with iOS 17.0.2. I tried setting it up by transferring data from my old phone or an iCloud backup and it didn't work in either case:

  • Transfer from old iPhone: at some point, I get stuck on a page asking me to update iOS but nothing happens
  • Backup from iCloud: unable to proceed because the backup is from iOS 17.1.2 and iPhone is running 17.0.2


I then set up the phone as a completely new phone and tried to update the iOS version from the settings but it still doesn't work. I get the following error "Software Update Failed - An error occurred downloading iOS 17.1.1"

@sberman: the iPhone is proposing to update to 17.1.1 / doesn't allow to choose 17.1.2.

I can't remove and download the update again given the update is not even downloaded.

Force restart the iPhone as follows:


  1. Press and quickly release the volume up button.
  2. Press and quickly release the volume down button.
  3. Press and hold the side button.
  4. When the Apple logo appears, release the side button.
