csteinmetz1 , if that's the case, you can use the v9.0.50 firmwares here

Just download any firmware that your feel is almost similar to your player, and modify it.
To modify, use S1res tool, guide is here

Once done, flash the modified firmware into your player, guide here

If it is compatible, the player would startup with a new theme. However, mostly likely 99.9% you would brick it instead.
Either way, to save your time, i'll suggest that you download and flash the firmwares in directly rather than wasting time theming and then flashing. If the firmware does not work in the first place, there's no point theming it.
