Tried the Dead Player Recovery Guide but...
 

i can't get XP to detect the device as an ADFU device..
When i try to Update the driver by right-clicking the Unkown USB Device in the device manager like stated in the Guide, i get this message:

"The specified location does not contain information about your hardware."

The player have a blue BG with a sandglace
Chip: SAMSUNG 646, ATJ2091N
4GB

I also tried this ADFU driver, no luck:
