finally it has worked.
i tried on a different computer. i thing my usb ports was damaged.

But it seems like problems will never finish . i cant find a proper firmware for my fake sony 1 gb mp4 player that has ak1025 chip.
it's original firmware was 9.0.48 .
I've taken a back up with "s1fwx" but it's not working.
I searched lots of web side but couldn't find any firm ware like ak1025 9.0.48
