BOTTA19810 , the Samsung K9G8GO8UOM is a 8Gigabit (1GigaByte) memory chip. So your player originally was hacked to show 4GB rather than 1GB.
But anyway, if MP3 Utilities Upgrade Tool does not recognise your player, then you'll need to follow the Dead Player Recovery guide here

If your player is detected by MP3 Utilities Upgrade Tool, then you'll need to try all the v9.xx firmwares for your screen size here

As there is no way to tell which firmware would function with your player, you'll need to try all of them until you get one working. Good luck.
