Hey all, saw an OTA come through which seemed like it all went through ok, but kept giving me a flashing grey screen when trying to access the Android home screen. Digital tv and HDMI inputs worked ok, just not home.

Quick Google taught me how to reset the unit (power off unit at the wall and then power on while holding vol down & 'power' button).

Everything seems to be all good now though need to remember all my settings and disabling apps via adb now!
