Lumia 1020 closes down on its own after updating to Cyan

[WPCentral Question]

After updating my Nokia Lumia 1020 to Cyan it closes down randomly - anyone who knows how to deal with it without resetting the phone?

I am having exactly the same problem. I thought I had just resolved the rapid battery drain issue and now this morning my phone just died and nearly 4 hours later, I cannot get it back on. I have it plugged in to power also. I would so appreciate it if you figure this out and share the info.
