MyMPx.org - HY2UU08AG5A -AK1025 -firmware please

It's a fake 3rd generation IPod nano of 8Gb, which didn't last a day. When i turned it on it did work. But when i plugged it to the computer it detected two partitions, and the computer asked me to format one of those, and not the other. When i did as asked the player stopped working. The only thing that appeared was a blue screen of death with an hourglass.

I have downloaded many firmwares, and none of them work. Sometimes the device is detected as an ADUF, sometimes as a hard disk, but with only 2Gb.

-Memory: HYNIX HY2UU08AG5A
-Chip: AK1025
-Board: XT-9124 V4 2005-03-05
-Screen: XY-1.8C KM080812

I have been unable to find that board model in any of the pages that i searched. I only found a model of that brand, a XT-9115. But it doesn't work. I don't know what firmware it uses since i didn't looked for it before formatting.
