Can you downgrade from iOS 26 beta to iOS 17?

[mectojic]

iPhone 15, never updated to 18 because why would I? Mainly hated the Photos app.
But iOS 26 looks visually interesting, and has fixed Photos.

Can I test the beta and then downgrade back to 17.7 if I don't like?

No.

You can only restore the current release.

 

[now i see it]

buy used iPhone 11 for $120 and use it as your ios26 guinea pig instead
