I have a LG G watch, about 2 months old, purchased new. First, let me say that I have flashed nothing. The only that thing that happened is that last night I changed the plastic band to a metal one. I made sure it was fully charged and went to bed. Got up this morning and the screen would not wake up. I feel vibrations occasionally, but no video. When I first got up I thought, wow, it really drained the battery completely, how odd. So I put it on the charger. But still nothing. Completely blank. I have tried powering it off and on again and I have tried resetting it. There are vibrations when I place it on or remove it from the charger. Any hope? Not sure about warranty protection.
