Is there anything wrong with your player right now?
If not I would higly recommend you *not* try to upgrade the firmware. All you need to do is look "Dead Players" section of this forum to see what I mean. You have a much higher chance of having a dead player from flashing it with an incompatible firmware than to find one that is going to improve the functionality of the player.
