LiM92 , currently the firmware extraction tool S1fwx v3.1 can only support upto v9.0.43. The firmware dump you have extracted earlier has missing files. You will have noticed the DOS screen displaying some error messages when extracting. This firmware dump cannot be used as those files are missing.
It is impossible to extract Full Firmwares, only the manufacturers have the equipment and software to do so.
What i can suggest is that you try all the v9.0.xx firmwares in the downloads section here

If these do not work, there is nothing you can do until the tool supports your version and you can try extracting the firmware from your other working players to test on your dead player.
