So just before I ran the update for for KK my started to reboot on its own. It's been going on for a few days. I have tried to perform a factory reset which did nothing. Preceding all of this my phone would randomly lose connection to it's own SIM card and to any network. Even the WiFi networks it knew about. Like I said, I have performed a factory reset and it has not yet worked. I'm getting annoyed at this because it started all of a sudden. Please advise.
