If you'd like to learn how to make the best use of your iPhone, consider signing up for our free Tip of the Day. If you feel that reverting to the previous iOS version is still the best option for you despite the setbacks mentioned above, follow the instructions below covering how to uninstall an iOS update. Note: All iOS 14 versions and iOS 15.0 have been unsigned by Apple, so you can no longer downgrade your iPhone software to these versions. To quickly check this, go to and select your device and desired software version to see if the iOS is still signed. If the software version is no longer signed, Apple has stopped supporting the iOS version and you cannot downgrade.


While you can still use an earlier backup, you will still be losing some data. This is because a later version backup cannot be used after you downgrade to an earlier software version.

You will lose any data from after your latest iOS update.
