Of course it will never work for you because you misplaced the bios file of the HP ProBook 450 G5.

Hello, it looks like your original BIOS is damaged, I can't create a patched file from it.

Attempt to read the BIOS file at least 3 times and compare them so that they are identical.

"IMPORTANT: Before applying the patch make sure you verify that your original image is not corrupted by dumping 1 or 2 additional images from your bios chip and comparing them.

The original dump is THE ONLY WAY to recover your machine if something goes wrong!"

Hello hoaca388 you may be right with your assumption.

The file can't be patched at all, then it doesn't make any sense.

If I search wxHexEditor for L470, it just shows me the result as in the picture.

I wish you a nice day.

Your information is not wrong, don't know what he did before but that file has a part in the bios region that belongs to HP, the rest is from Lenovo.
