HYNIX HY2UU08AG5A -AK1025
 

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.

Your flash is only 16Gbit = 2GB, so that is the real capacity.

If you can get it to function as USB drive, it means the firmware core and Udisk driver is already compatible. Now you just need to find appropriate driver for the display and keyboard, and build a firmware in that way.
