technodummy , install the MP3 Utilities, and start the Upgrade Tool. If it does not detect your player, then you will need to perform the Dead Player Recovery Guide.
When your player is detected, then you can start trying all the v9.0.xx firmwares.

Your player would be using the v9.0.xx series firmwares, so try everything in there.
As currently the firmware extraction tool does not support any versions above v9.0.43, you might not be able to recover your player as there is a very limited number of firmwares uploaded by other members.
