jose111 , at this moment, the firmware extraction tool S1fwx does not support v9.0.48, so you would have problems finding a suitable firmware.

Try using other v9.0.xx firmwares. Also you can ask your seller for if he has the firmware to send to you. And search in the CD that came with your player, sometimes the firmware file is inside. It should be in .fw or .bin extension.
