That was the last OS I used for which the acceptable troubleshooting solution was to “format the disk”. 20 years later and I came to the same point with this iPhone 7, thought that we had left that behind us. And I can’t even do it myself, I have to wait for the local Apple service store to open, which it won’t until January 6th (the phone broke down on December 27th). But hurray! for the new color, I guess.
