Upgrading to the latest iOS version can be exciting, but sometimes iOS 26 may not meet your expectations. You might experience unexpected bugs, slower performance, app incompatibilities, or simply prefer the features of your previous iOS.

This guide will walk you through everything you need to know - from backing up your iPhone safely to several methods for removing iOS 26 without losing important data. By following these steps carefully, you can restore your device to a more stable or familiar environment.
