username , likely that you might be running off an ATJ2085 chipset, as it is the most common for this version number. However, it is better to open the player and check the serial number, as sometimes it might be a different chipset.
So currently it does not get detected by the Upgrade Tool at all? Then you will need to do the Dead Player Recovery
Here.
Once done, and a Full firmware is flashed in, continue to try other firmware dumps which you have not tried before. This is where the serial number from the chipset that you have located comes into use. It would be easier to find a related firmware dump with some kind of info, rather than wasting time and trying random firmwares.
