Running iPhone 15 Pro Max ios 18.1 beta installed not showing an update to 18.5 anyone have any idea why that is and how I can get the update. cheers
Software update not showing iOS 18.5 beta
If you have 18.1 beta installed then you cannot install 18.0 beta 5 because 18.1 beta is newer than 18.0 beta 5.
If you want to downgrade to 18.0 beta 5 you will have to wipe and restore from a backup (which is at 17.x or 18.0 beta 1-4), then install 18.0 beta 5.
