Problem installing the new ios 16.3.1
I am trying to update my iphone 11 pro to the latest ios. 16.3.1 and nothing works. It complains about the network but I have been to the shop where we had perfect connection and it still does not work.
It says that the update cannot be verified because that I am not longer connected with the internet.....try again?
....
Also when entering the ITunes account I am not able to reboot the device from scratch. That button is gray.
