Help! Nowhere to find this firmware

[trinca]

Hello, I got these MP4 player clones, iPod branded, with the memory exploit.
Although the NAND Flash is 8Gb (8bits x 1024), when formatting it gets down to 1GB, in the process the FW gets corrupted.

I was able to retrieve the picture the seller used to sell this MPX player,


I don't know chinese, and the characters on the picture should been OCR, however IRIS OCR gave me poor results, no matter how much effort in enhancing the image. So I decided to use an online program the name of *mouse* to Chinese. where using the mouse you atempt to draw the strokes of chinese characters and they gave you alternative chinese characters to match your drawing.

After many, many tries, I was able to get the charactes from the picture and those are:

深圳邦仕德

Now, googling the above gave me the result of

SHENZHEN BOOSTDO ELEC-TECH CO.,LTD. who makes MP4

At here, I came to a dead end, as this company does not seem to have a website.

On the other hand I found this as:

深圳邦仕德SONY
And it translates to SHENZEN Bangshide SONY, and this seems to be an outlet store.

Am I on the right track? Do you have any hint? I Hope S1FW can help me further.
