You can’t downgrade to iOS 18. If you are having problems with iOS 26, describe them here and we will try to help you.

Bottom line? You can’t, end of story. Apple has never supported downgrading of iOS.

Perhaps you should explain why you wish to downgrade. Maybe we can help with whatever issues you are dealing with.
