I'm having the same issue as well. Did all advised and watch is still attempting reboot every few seconds. Was on charge for a couple hours and went to put it on and noticed this happening. Tried charging again and the logo pop up, line flash and vibration continued on charger. So I searched here for an answer and unless I'm overlooking, no one has reported anything has worked for them. So frustrating since this is a replacement watch after last one got super hot on the charger and would not turn on. That was preceeded with charger not working and taking a couple weeks to get a replacement and before that my old Ionic was recalled at which time I was able to send in for a discounted Sense, which was no deal at all. So, I've been without a watch for several weeks of the past couple of years. Also was charged for a year of Premium I've not used. Going back to Garmin.
