Hope i'm posting in the right spot here. But i'm trying to find tools and methods for unlocking newer HP business laptop BIOS files (elitebooks, probooks, zbooks, etc) both Intel and AMD.

I see posts of people successfully unlocking the files here but nobody discussing the methods. Just wanted to sum up my research and thoughts - will update as i go.

1. Older tools such as RCUnlocker and HPUnlocker do not work with newer HP models. Comparing input and output files they appear to work by trying to manually set a few bios setting flags.
Trying to flash these files...

rex98 thanks for much for posting this tool, it's been very handy when i've had a dead board or just forgot to run the BCU tool. I noticed the source provided wasn't complete and I was running into some parsing errors so I took a stab at things.
It can now detect the FeatureByte and MAC a bit more reliably and I included the UUID. I don't know if its ok to upload a .exe here so i'll just dump the C# source here for now....
