I wiped my iPhone 5s, but in the process of re-setting it up, it says "verification failed, there was a problem connecting to the server" after I tried submitting the two-factor identification code- even though the wifi is working. I tried to call apple support, but I have to have some "IBN"(?) number that I can only get to by going to settings, which I can't do because my iPhone isn't functioning yet. This number supposedly also comes with the packaging which I don't have anymore because I got the phone almost a year ago.
So, right now I'm stuck with a phone that won't log in, and I can't reach customer support about it. I've tried doing a hard reset with the lock and home button and retrying, but it won't work. What do I do?
