thx a lot but I think that the problem at the moment is the bios. in my opinion is bricked and I can't return to the original one

Goodmorning everyone, I have for several years now an old w110er branded by Schenker in Germany. Due to Overheating I upgraded bios with Premamod v3, after this update, the monitor began to flicker. so I did the downgrade to the original bios to revert to a working configuration. after performing this procedure as described on the notes the laptop turns on, the monitor remains black and the fan does not run. I tried the recovery operation with the bios file on usb properly renamed and turn on pressing Fn + B but nothing happens. What can I do to revive it? I thank you in advance
