Hello everyone, I have an HP 820 G4, I have tried to read the bin file in order to unlock but I ended up with a black screen and three beeps, I think I read the wrong bios Chip, Is there any way to fix it ? I will upload what I read at the beginning and what I have now on my chip

With all of them I get two long beeps and twos hort ones, As I said I think when I tried to read the bios I read it with the wrong chip ID, Is there any solution to get it back to what it was ? I tried putting bios recovery on a USB drive but nothing
