mazhius , firstly install MP3 Utilities, there are many versions in the downloads section. Once installed, check if the MP3 Utilities Upgrade Tool or Disk Tool is able to detect your player.
If not, then you will need to perform the Dead Player Recovery, guide here

If it can be detected, you'll need to identify the processor's serial number. To do so, you'll need to open the player and check for the serial number (eg ATJ2085, ATJ2097, etc).
Do these few things first and let me know.
