I tried to reset based on posted suggestions and it does not work. It is stuck on the connected screen.

Hold the power button longer. As I said, it sometimes takes longer, sometimes up to a minute or more. Remember, you must do this with the player not connected to your computer.

If it is truly stuck and stubborn, the only thing you can do is wait for the battery to run out and turn off by itself. Hopefully, it will reset itself in that progress, or at least allow you to reset it after re-connecting it to your computer to re-charge.
