Dead Player. Need firmware please
 

Hi everybody. I have a MP4 Player no-brand, no-name (on his plastic stick write MP4 digital audio player) wich is almost dead. it's starts, work the radio only, i can conect to my pc but i can't copy or delete anything from him. So, i need a firmware for my player.
After reading many post from this site i remove the plastic stick and under the LCD i've found the Board ID : ZX-882M-SLS-V1.3 and 20061124.
Other specifications : AK1022, and in the menu at firmware version section appear AK1022 2006/06/25 9.1.52.000 2006/12/28
I search on google but i still don't find the firmware for this player. Please help me.
