Use an ipsw to Manually Upgrade an iOS Device

Recently, I needed to test the behavior of something during the upgrade process of an iOS device. The device was running the latest version of iOS so I needed to use an ipsw to load a specific version of the OS. Usually I use Configurator for running a lot of updates, but I didn’t want to restore the device, so I used iTunes. After I backed up the device, here’s what I did:

  • Download the ipsw file from Apple for that specific device
  • Connect the device (make sure Configurator isn’t open, enter a passcode if needed and then launch iTunes
  • Click on the device in iTunes (You might need to show sidebar if you don’t initially see it)
  • Click on the Summary tab
  • Option-Click on Check for Update (Alt-Click on Windows)Screen Shot 2014-08-28 at 11.17.47 AM
  • Select the ipsw previously downloaded
  • When prompted, click Update
  • When the device reboots, wait for the status bar and you should be all done

 

 

Good luck!
