Failure during a BIOS upgrade turns your PC into an Electric Brick -- so none of the things you have tried will do any good.  The BIOS needs to be reflashed.

You can try following these instructions:  HP Notebook PCs - Restoring the BIOS | HP® Customer Support

But, if those don't work, you would need to take the laptop into a Service Center to get the BIOS replaced.

If you live in the U.S., here is a link to the HP Service Repair Centers:

If you live outside the U.S., here is a link to HP Service Centers, by Country/Region: https://support.hp.com/in-en/service-center
Good Luck
