MyMPx.org - Looking for IPod Nano clone FW

Hi,

I'm looking for the firmware for this player I bought on DealExtreme. All I can see is:

BKS25056_MV6A
NO: 071116
Kee
ROHS

hynix kor
hy27uuo8ag5m
tpcb 735A

Already tried all the firmwares on S1FW.com, but all they give to me "Invalid upgrade firmware file!". I think the correct firmware might be this one, as the pictures are of my same MP4 player:

But I can't download it.. I don't understand chinese at all :(
Can anybody help me?

Thanks in advance!
