I can't update my iPhone 6s to iOS 14.8
I tried to update my iPhone 6s to the latest update, 14.8. I get an error message saying it can’t be updated so I try to restore it to the backup. Then, I get a message that it can’t be updated or restored. Suggested I turn off phone and computer. I did and while rebooting my computer upgraded. Now, I want to try again. Any advice?
