sharon_1 , your player would be using the v9.xx firmwares here

You'll need to install MP3 Utilities, there are many in the downloads section here

Next, start Upgrade Tools and see if it detects your player.
If it does, then you'll need to try all the firmwares for your screen size in the link above.
If it does not, then you'll need to perform a Dead Player Recovery, the guide is here
