This morning I started to use my iPhone X, which I've received on launch day last Friday. I've noticed that FaceID gave me the message that I had to use the passcode when the device had rebooted...didn't put much attention to it. After checking something, I've put the phone back in the sleeve and took it a a few minutes later. It gave me the same message .... weird .. Tried this a few times and saw that the phone was rebooting almost every time I took it out of the sleeve. Did a few test without the sleeve and the first tests seem t work,...but after an hour or so it started to reboot again (showing me the Apple logo). Also I had to do a hard reset a few times, because it got stuck in a boot loop. Called Apple, did some diagnostics and they told me to install as a new device using iTunes. It was at the end of their working day, so the guy told me to do the fresh install and start using my device again. 10 minutes later iTunes gave me a message that recovery was not possible error 4013. Tried a lot of things (different MAC, download a signed IPSW, tried another USB cable ..) nothing helped. So tomorrow I have to call them again to start a "repair proces" .. on a Dutch forum there is 1 person with the same issue. He has to wait till mid december before he will get a new X :-( Not happy with this ..
