The same thing happened with my 8 plus. I finally got in touch with a real Apple expert. After running remote testing, one test came back as a failure which was Presence Test Baseband. I have no idea what that means, but my expert did. Instead of dismissing me like everyone else as being unwilling to accept a hardware problem, she took me at my word that it was software related. After being told not to do a full erase/restore by the other Apple techs because it might make things worse, this one said to do it. I erased everything back to brand new, but did not restore it from icloud immediately because that could have brought back the bad update. We verified that the phone was working without restoring anything. Then we did a second full restore from the icloud backup and this time the update installed correctly.


Steps taken:

  1. Back-up phone to icloud or computer.
  2. Erase without restore, verify that phone and texting works. Your mobile provider should now show in upper left corner.
  3. Erase again but this time restore from icloud to get back your contacts, apps, etc.


I hope this works for everyone else. They all told me it was a hardware issue and I would have to pay to have it fixed or buy a new phone. They were wrong.
