Hope this helps those with fringe model iPhone updates.

Perhaps to try for iOS 15.7.5 instead, as that should be supported

by an iPhone 7 Plus. ~You may require use of a computer PC/Mac

& a cable, for that to happen. An older computer with windows, or

older MacOS uses iTunes; later than Catalina, uses Finder.

Have you tried to get the download, to an iPhone from WiFi, with

the phone on charger and try the built-in system updates?

..If not, then it's first in line to attempt..

Otherwise, someone would have to be

certain you get detailed instructions.
