I checked right after allaboutbuzz posted this thread and it said update available but will say reboot without installing. so I tried to reboot and nothing changed. it said update available from Home Screen, setting as well as from buzztv app but won't install. so yes I tried as you mentioned as well as left ON for hours too, turned off for some time too and restart and nothing. now it says no update available and still has not update. I will leave it on until Friday and see if any change otherwise factory reset is only option.
