Update IOS before restoring backup
I just bought a "new" phone (it's a used phone) and went to my provider to transfer service. The service is transfered, but in order to restore my iCloud info, I need to update IOS on this "new" phone. Non of my backups are available until I update. How can I get to the settings? So far, the phone wants to walk me through the whole set up process, and I can't get out of those prompts.
