I've tried just about all those things.
Held the power button down (for at least 10 sec): nothing
Pushed the soft reset button on the bottom and then tried power button: nothing
I've taken the battery out 6-8 times, reseated it, and retried: nothing
Plugged charger in with battery cover off, wiggled the battery to try to make a connection and I"m still getting a solid red light. If the charger is plugged in with battery out I get flashing red light. CAn't get green light.
I'll try these suggestions specifically, in case I did something slightly off.
