I just bought a 1gb 1.8" player for my gf and the volume button doesn't seem to be programmed. There was no firmware on the disk that came with it so I can't try reflashing it unless I can find firmware for this model somewhere.
I took the unit apart and there are no PCB markings. The chipset is ATJ2085W.
The firmware info says....
F/W Version
Core: PMA300_010
Date: 20006-03-15
FW: SRX-3.5.37
Date: 2006-03-24
Here are a couple pics of the player...

Any help on editing the firmware to program the button or newer firmware for this model would greatly be appreciated.
