Hello there tadad. Thankyou for response. I just use basic steps to recover player: I follow the guide on how I have to short chip from here:

Then i match my board with fw & download 3.5.35 fw on s1mp3.org & upgrade my player inside upgrade tool. Then my player is good to go.
Thankyou to all once again.
