MyMPx.org - Looking for firmware Samsung 631 K9L8G08UOM

Hi, I'm looking for firmware for my DEC-A640 player

On it is written
SAMSUNG 631
K9L8G08UOM
PCB0

Another chip says
TEA5767

This mp3 has a 1gb capacity, and its not a new one.

On the MP3 firmware upgrading tool, it says
S1 MP3 Player
Wilson Co. Ltd.
Version: 9.0.42

It had stopped working for quite a while, so when I came across the DEAD PLAYER RECOVERY GUIDE, I followed it until after I managed to get my player to show on window's explorer. Now, I am stuck because I am unable to off or on it, it only displays a white blank screen. On the computer, I formatted it and tried to load the dump.bin file using the MP3 player firmware upgrading tool but the one I have is wrong.

I downloaded the recovery firmware from the official website www.digilife.com, but am unable to identify which is the dump.bin file

Anyone with this firmware or can help me find out where it is available?

Thank you ! :D
