Hi saroz
Generally all you need is finding a default resource file and paste it over to your player and reboot. Make sure you getting one from same firmware version that you currently having on your player.

You can find some here:

If you not sure what version you use, just do a full firmware upgrade and it will be all fine. Just remember to backup your files.
