iOS Update Crashes iPhones: How to Fix

The iOS 10 update breaks iPhones and iPads forcing users to connect to iTunes to restore or to update with iTunes to continue using the iPhone.

When connecting to iTunes to fix the iOS 10 bricked iPhone users are encountering long download times for iOS 9.3.5 and seeing iTunes error 1671.


If your iPhone or iPad is bricked with iOS 10, you cannot use it for potentially the next several hours.

Users who have not updated to iOS 10 yet should pause and not update at this time. It is possible that Apple is pulling the iPhone update.

Our iPhone SE is bricked and connecting it to iTunes offers an option to update and keep settings and data or to completely restore the iPhone. Downloading iOS 9.3.5 is estimated at over three hours. During that time I cannot use my iPhone SE for any calls.

On a second try iTunes shows, “There was a problem downloading the software for the iPhone”iPhone name”. An unknown error occurred (1671).”


If you are impacted by this problem, you will see an iTunes logo with a Lightning cable and you will need to plug into iTunes to recover.

Once plugged into iTunes the app will ask you to Restore or to Update. Try to Update first.

Hopefully you can update to restore instead of doing a complete restore that will wipe your iPhone.
