amyr , there is no use trying to extract your firmware using S1fwx, as currently it only supports upto v9.0.43, your player is using v9.1.52.
This also means that you'll have a problem of locating a suitable firmware as others are unable to dump their firmware for you to try.
You have 2 options, the easiest would be to contact your seller for an exchange if it is still under warranty.
Or, you can try flashing all the v9.xx firmwares one by one until you get a working player, list here
