xanto1200 , firstly the Samsung k9g8g08u0m is a 1GigaByte memory chip, not 4GB, it was hacked to show 4GB instead.
As for firmware, your player would be using the v9.xx series firmwares here

But as there is no way to tell which firmware would work, you'll need to try all those for your screen size until you get one working with your player. Good luck.
