dang_para,
Dowload this tool:
UDisk Checker from
here.
Plug in your player and run it.
It will tell you what type disk/solution your player is using.
If it says "Sunplus" or "Sigmatel", then the tools on the s1fwx tool on this site
won't work for your player and can't extract your firmware. I have yet to get a hold of the Sunplus or Sigmatel firmware extraction tools.
