Wragler , unfortunenately there is no way of telling which firmware dump is suitable for which player. It is all a matter of luck. You just need to keep trying various firmware dumps.

Once you have tried all the available dumps and none works, i'll suggest that you try another Full firmware. Which means you'll need to short the player again, and get it to accept another full firmware. As sometimes, you will also need to try various combinations of Full and Dump firmwares to get the player working.
