I have an old iPhone 6s that hasn't been activated since the 7 came out 😂 but I still use it sometimes and it's got a lot of information on it. I cut it on and it was asking for WiFi info like it had updated or something but I set that up then it said it was activating and may take a minute then said activation error and won't do anything. How do I fix it. At least to back it up and get my stuff
