If you’re attempting to downgrade from a future iOS version to iOS 10. 3, for example, you’ll be able to do so within a week of that software’s update.

Any red links are IPSW files that are no longer being signed by Apple. These files won’t work on your iDevice. If you’re already running the older version of the two IPSW files listed here, you can’t downgrade.

Depending on your browser, you may first need to select a save location (e. g. , your computer’s desktop). Your IPSW file will likely take around half an hour to download.

You may be prompted to click Download iTunes if there is an update available. If so, update iTunes and restart your computer before continuing.

You must first disable the “Find My iPhone” feature if prompted to do so.

Once the process is complete, you can restore a previous backup to get your contacts, photos, messages, and so on back. This backup cannot be from the subsequent iOS version, or your downgrade will be lost.
