Digital Player MP4 2GB Firmware
 

Hi everyone
I'm searching for my mp4 firmware.

It's a nano like 2gb no brand:
Cpu -- ATJ2085H
Memory Chip -- Samsung 616 -- K9WAG8U1A
Battery 3.7 V 230 mAh
Oled Screen 128x128 -- FC0340 FRE 060601
Main Board mod. MP-693C-SL main V 1.3 12/14/2005

The original Firmware was 3.5.37 LISONG... (i can't remember) with Games , Radio FM ( with JAP and EU Frequency) and recorder.
I have tried everithing that i've found with google like 3.5.35 and 3.5.37 , but nothing to do, the player is still live. I can see it like a mass storage of 2GB, but the screen is Blue and if i push the Play button , i can hear my music only from the right channel.

Please HELP me!! Thanks.
