Hi andyp8520,
Do you have a similar player though?
Remember, you need to make sure you get a firmware that is COMPATIBLE with your player.
Best to open your player up and have a look for the Chipset and board ID numbers on it so you can do a search for it to see if you can find one similar.
Have a look here
