How can I downgrade from iOS 26 to older version on iPhone 13?

If you had installed the iOS 26 beta and wanted to get rid of it, you could have done that with the aid of a Mac or Windows PC. At least, before Apple released the production version of iOS 26.

I don’t think you can downgrade from a released version of iOS to a previous version.

Hello~ Downgrading is not supported. If you’re updated you will need to get used to it.

The original response remains correct, downgrade is Unsupported. If you want to wipe your phone and start over like a factory reset (no saved data, no restoring a backup) you are welcome to the pain.

That’s not true. Check my post!

What? Android phones don't have anything close to Apple's Liquid Glass, so NO, iPhones don't look like Android at all. But Katana-San provided the correct response. You can't downgrade, so you may as well get used to the new and IMPROVED in my humble opinion iOS 26.

You can downgrade by resetting your iPhone 13, assuming you backed it up on iOS 18, 17, or 16. When setting it up, you can then choose the backup. P.S. IOS 26 looks nothing like Android🤣

Hello~ Pardon?? I am not here to argue…simply stating the facts.
