Dead Ipod nano clone 8 GB

[cruzzi10]

Hi,

I got an Ipod nano clone from a friend.
When I turn it on, it only shows a hourglass on the display.
When I connect it to my PC, Windows detects new HW but asks for drivers which I don't have.

I guess the player was flashed with the wrong firmware.
I tried to google the board number, but I could not find anyone with the same board and the same memory.

This is what I see on the motherboard:

Board: QS91B18S V0.3 KEY
Memory: Toshiba TC58NVG3D4CTG00 (should be 8 GB)
Chip: AK1025
Display: XVXW029-1 090331-A2

Any clue on how what firmware I should use?

Thank you,
