Since I had been having rapid battery draining issues (2% per hour) since the last 2 weeks, I had done a complete watch reset a few days back. The battery drain issue wasn't sorted, but at least I had the watch running fine. Today, I thought of trying to restart the watch and see if that helped sort the battery drain. Alas, after switching off, it wouldn't come on irrespective of any button that I pressed. I then connected the watch to the charger, and voila, the screen came on, but is stuck in the "DESCENT" boot up screen. Now, I can't switch off, I can't restart, nothing. However long I press the LIGHT button, the watch does not go off. Holding START/STOP and BACK for any amount of time does nothing. Holding both down along with LIGHT does nothing. Now I have no clue how to get this up and running again.
