HP Probook 640 G5 i5 8th gen Touch screen - Bios Corrupt

Good day all, Yesterday i tried to create a dump of my bios so i can try to delete admin password. I noticed after every read i got a corrupt dump. (was trying out a new wson8 test lead adaptor). Now the laptop only has a flashing caps lock and no signs of life. Very possible this new test lead caused the issue.
How can i go about rebuilding a compatible bios for the laptop?

If youve got corrupt reads you`ll have corrupt writes.Solder wires to the pads instead or desolder the chip,solder to an adapter board or use one of those adapter boards that has a lid that locks down, and hope it can be read.You might have corrupted the bios data or damaged the chip.

Yes i have ordered a adaptor board and hoping for the best, but with my luck i might as well order a new chip and try to build a bios for it.

Thats why i asked for a bios dump so i can start working on a bios rebuild, i just not sure where all the info is stored in the bios. as for mac address thats easy just the other dmi information
