This has been repeatedly answered, by multiple contributors, throughout the six pages of this discussion thread...


If you are currently enrolled in a beta programme and wish to return to using the current production version, this support page provides the necessary information to remove the beta from your iPhone:

Be aware that restoring an earlier version of iOS will completely reset and erase your iPhone. Assuming that you have a pre-existing iCloud or iTunes backup of your iPhone that has not been updated since installing the iOS 26 beta, your locally stored data and files can be restored after returning your iPhone to iOS 18.5; if you don't have a pre-existing backup, all locally stored data will be irretrievably lost:

An iCloud or iTunes backup can only be restored to a device running the same or later version of iOS than created (or last updated) the backup. As such a backup created or updated by iOS 26 cannot be restored to a device running iOS 18.5.

Kindly post the article that you're referring to. <3


Without a computer and a backup made prior to the beta install, a user cannot go back to a non-beta iOS. This is why it’s imperative that when we use the beta, we read everything carefully so we understand what we're doing and that we cannot go back to the original iOS unless there was an iTunes backup first. <3

At this point you are better off waiting for the release version, although you can certainly read the information that has been provided here many times. I am sure you could not have missed it, but if you tried you can follow up what did not work for you.


There is no way to go back to iOS 18.5, the latest version that can be restored to is iOS 18.6.2.

Report issues found to Apple or to third-party app developers.


Resetting to revert to iOS 18.6.2 means no local data is preserved.


Resetting and restoring means some local data — that which has changed since the beta was installed — is lost.


If there are no backups created immediately prior to the installation of the beta, all local data is lost.


iCloud data is probably still available, and apps can be re-downloaded, independent of the reset.

But I’d likely stay with the iOS 26 beta through its upcoming release, as that probably avoids data loss.


Apple is having an announcement on September 9th; Tuesday.

It’s the iOS 26

You just added to a 22 page thread where it has been said perhaps a hundred times that you cannot downgrade from iOS 26. Thus, it would pay to read at least a few posts in a thread before asking the same question that has been asked dozens of times. Asking again isn’t going to change the answer.
