Hi, My Xperia XZ2 is about three years old and worked perfectly, until yesterday. WIthout any reason it restarted, and before the restart was complete, already restarted again. The only thing I can do is turn it off but when I turn it on, same thing. I used Xperia Companion from my PC to re-install software. That works, but when I remove the phone from PC, the setup-procedure starts, but does not get finished because it restarts again! Any suggestions?
