That is not a firmware issue, it is a deleted battery. It works when plugged in because it isn't using the battery. They are no longer doing firmware downgrades and it would not help you anyway. You can try a factory reset but it is likely time for a new watch. TT does not offer a repair service and that product was discontinued years ago (TT Sports went out of business almost 3 years ago). There are plenty of brands out there with better feature sets for less money these days.
