Sorry , My board Id: SAMSUNG 640 - K9LAG08UOM-PCB0
I copy info another post, now I checked and I see above board id.
Mp3 player utilites are detecs some time, but some time give a error message "not supported disk" e.t.c. I formated low mode whne mp3 utilites able to detect my player. But then I re-connect usb, windows want to format. I tried format in windows (fat only because fat 32 is not correctly finishing). After then, I tried fw update tool, but its give me "read and write error" and I back to begining...
Thanks for interest... (so sory my language
)
