Once you get the player recognised by the computer and upgrade tool, you can start testing firmwares.
For your player it is using the ATJ2093 chipset, which uses the v9.xx firmwares here

You'll need to try all of them for your screen size, until you get one working with your player. As there is no way to tell which would work fully with your player. Good luck.
