- How to do a hard reset? 2 answers
I was stuck at 21% in my restore with a new Lumia 950. I kept getting this message box with two buttons "Don't Restore" and "Try Again". The message ends with: "...If you tap Don't restore, you won't be given an option to restore your backup later."
I turned it off to try again, but that didn't help. How can I start over?
