[Deicide]

Could you help me find firmware for my Mikomi mp3 model #513/3848.
As far as I can judge the board number is FM662531.1 (that's what's written in white on the board right behind the display and there are no other numbers there).
Proc.: Sigmatel STMP3502 L100E-CA6 A00581 0632

P.S. I spent 2 days looking for the firmware with no result. The player stopped responding after my PC froze down during the write/read operation. And the bundled CD has only the drivers for Windows 98 with no firmware on it whatsoever.

Thank you in advance.
