So I don’t know what happened but my iPhone X downloaded the 11.3.1 update and then had the install option. I go through with it and it starts doing its thing. Half way across the update bar and logo the phone prompts to connect to iTunes. Great. I go to apple store and get them to try to update it - nothing, unknown error 7, try to do a fresh restore, same unknown error 7. Eventually after 4 tries they just replaced my iPhone X. Now the specialist at Apple said that it could have lost WiFi connection? Okay, plausible but I already downloaded the update just had to install it, seems like it might have something to do with it. But why doesn’t the phone just revert back or something? And why does this prevent a restore of all things through iTunes? Anyone ever witness this?
