I just received my HC-2 a week and a half ago. Since then I've used it a few times on different days. I've had on again off again charging issues. Earlier this week, I had to use the toothpick reset/charging method and it worked fine. After that, I [supposedly] updated the HC-2 software. Yesterday I downloaded some files and sent them to an LM-2S, so I had a pretty eventful day. I put it on the charger yesterday afternoon to charge. Last night after it was finished charging (Done screen), I took it off charge. It was unresponsive and stuck on charging done. I did the toothpick method last night and went to bed. This morning is the same issue. Charging Done screen. Even when I take it off charge and let it time out (screen off), when I press the on button the same screen comes back up. Resets, plugging/unplugging, plug charger into power, unplug charger from power all give the same nonresponce. Has anyone had a similar issue that could give guidance?
