"no backup from iOS 17: so i updated to ios 18 when it first came out and i haven’t updated it to the current release of ios 18 but when i found out that it was really buggy, i wanted to switch back but i didn’t find an ios 17 backup to restore, so i was wondering if there is any other way to convert back to ios 17."

Note that the backup needs to be of the same iOS that is installed, if you want to use it. Lean More here: Removing Beta Software: How to Uninstall iOS or iPadOS Beta Software - Apple Support
