iPhone 13, iOS 26
Question marked as
Apple has never supported downgrading iOS – except in the special case of removing a beta test version. If you've upgraded to the released version of iOS 26, you can't go back.
Apple is not here in these forums to answer your "why?" question. I could make an educated guess, but it would not let you downgrade to iOS 18.
