I did an OTA update on my note II last night. Watched it go through the whole thing. Seemed to work well. Even used the phone afterwards. Then put it down. It was on the charger the whole time. Woke up this morning-- black, cold, dead brick. COULD NOT get it on. Called verizon. Went through a bunch of stuff. No dice. I tried pulling the batter for 10 minutes, power+volume, with and without charger, etc. No dice. About 10 minutes ago, after tinkering with it all day I decided to pull the SIM card and the uSD card. Happened to "touch" the power button, it came on and booted up perfectly. Complaining about no SIM card. Anyway, it's working now. Going to power it off and put the SIM card back in it and see if it works.
