how to even install iOS 12?

[caleyfeli85]

I had iOS 11 beta but I deleted the profile after iOS 11 was released because it kept bugging me with notifications although there was no update.
How do I install the profile again to update iOS 12 beta? Every website I see explains how to do it if you’re not a member yet and contains downloading files to the pc.. I can’t remember doing any of that ?

If you have a device that will run iOS 13 or 14 you will not be able to install iOS 12 at all.
