Re: HP BIOS unlock tool

This method is not okay... You should warn people that MPM will be unlocked and all DMI must be reinserted again.


Try this instead - you just need to reset security settings to default after you get into bios.

where is offset to fix sir?

Re: HP BIOS unlock tool

Hi everyone, quick question: I'd like to avoid to desolder chip, since laptop si still under warranty for 6 months. For that, I'd like to dump EPROM with a clip (may not work, of course, since chip is still soldered).

First, did you have success with an in-circuit reading? Second, do you know where I can purchase a clip, but not an SO type, but a QFN type? (QFN-8)?

Thanks !

There is none to tell. Point me to your file, I'll do it manually for now.

First you would want to flash back both original files, just to see if that error disappears.


let me know if it disappears, then I will try to patch correctly.

Try this and let me know if it works or has any issues. Flash only EC bios.



You will get an error first boot, just ignore it. Go to bios, reset security settings to factory default. If you can restart successfully without any errors then it works. Please let me know.

Re: HP BIOS unlock tool

Nice. Do not use the same file on another laptop, you will brick it. Make copies of both chips, just in case and just send the EC file here. It's a bit tricky to get it correct.

Nah, this still needs main bios mod only. This should work fine and without needing any messing around with DMI.

Excellent friend RethoricalCheese, it worked perfect, but tell me I did it with your v1 tool, and it didn't work, did you do it manually? or I did something wrong thank you very much master.

Re: HP BIOS unlock tool

I did it with my new and improved tool which I have not published yet (because automatic unlocks on newer models is a bit more tricky than it seems. Still needs more improving and testing).
Old tool had a few bugs with certain bios dumps and your bios dump was an example of that.
