Idanbolig , if your player can be detected by the Upgrade Tool (which i assume you can, based on the screenshot), then you only need firmware dumps to try on your player.
I've done a search on the downloads section, seems like there is only 1 SC85051F firmware dump which was uploaded by me
Here.
If this firmware does not work, try other firmware dumps. You are not only restricted to this particular version. And the more dumps you try, the better chance of recovering your player.
