yeojharaz , your player would be using the v9.xx firmwares here

As there is no way to tell which firmware would work with your player, you'll need to try all those for your screen size until you get a working one.
However, as the firmware extraction tool currently only supports upto v9.0.43, you might have a problem of locating a suitable firmware.
Good luck.
