This is the bios which is working...

Little update, after testing many bioses i found one working from post 75, thanks hoaca388 , i did attach it, only serial number is generic 1234etc and no model number, maybe someone can put my device serial and model info in this bios? Everything is working ok now, nvme drives recognized only problem that nitro sense app shows system unsupported probably because there is no model number written in bios....

Hello, i have Acer Nitro AN515-57 with corrupted bios, i used CH341 programmer to make a backup and tried some bios files from this site but now i got no screen, blue light for few seconds and it switch off. With old bios i managed to switch it on, enter bios but there was generic serial number showing 12345etc with no model data and it didn't detect nvme drives connected. I tried to flash backup file now, but now I'm stuck with blue light for few seconds and that's it. Maybe i corrupted file when doing backup.
here is details about my device, i did attach backup bios file when it was switching...
