Hi. After upgrading to iOS 18 Beta, is there an easier way to downgrade back to iOS 17 without restoring your iPhone to factory settings? If so, I would want to know how to do this without the need of restoring iPhone to its factory settings. Thank you and have a great day.

You need to find a signed…
You need to find a signed version of the operating system. Usually when Apple releases an update, it is signed for around 7 days before it loses its validity and you are unable to downgrade. Get a signed copy, then use your computer and downgrade to it. You should not need to restore your settings, at least not the last time I did it.
Yes, if you have a Back-Up
If you have an iCloud or physical backup of your device running iOS 17.5 or 17.5.1 from before when you installed iOS 18 on it, then yes, you can restore.
However, this will only restore it to the time when your phone was on version 17, anything you have done since updating to 18 will be lost unless you already have that stored in iCloud (IE: iCloud Photos Library).
However, you still have to hook your phone up to a computer, put it into recovery mode and completely restore it to the latest signed version, which happens to be 17.5.1
From there, you’ll set up the phone like normal, but choose to restore from an iCloud or physical backup when prompted.
