How to upgrade from iOS beta or gold master to the official release

Alexandra Malureanu

by Alexandra Malureanu

If you're a developer and you're running a gold master release of iOS from the developer beta program, you'll know that often the gold master is binary-identical with the official release. When this is the case, there's no need to update. Sometimes, however, it's not, and there's not an obvious way to get onto the final release.

The answer calls for the classic backup, upgrade and restore. If you are not familiar with IPSW files or this process, our instructions in our guide to downgrade your iOS apply here.

Here are the steps needed, in order:

  • You should get the final release iOS IPSW from Developer Center
  • Download the latest version of iTunes
  • Connect your iPhone or iPad to your computer
  • If your iOS device asks to trust your computer, agree, and enter the code on your device
  • Back up the device -- we'd recommend locally to iTunes, as it's quicker both to backup and restore...
  • Hold Shift or Option, click "Check for Updates", and then choose your the IPSW to restore the image to your phone... erasing its content in the process
  • Restore the phone from your backup

This is iPhone Backup Extractor, think of it as a "personal forensics" utility. It's pretty awesome.
