HP BIOS unlock tool

[RethoricalCheese]

First check this site to see if your HP is supported for the great tool Mazzif has made.

http://mazzifsoftware.blogspot.com/p...os-unlock.html

If your model is newer and not in that list, you need to dump your bios, remove password from dump and reprogram bios with modified dump.

For that you need an SPI programmer like CH341A or Raspberry Pi with Flashrom or any other similar programmer. A soic8 clip is also useful so there wouldn't be a need to unsolder bios IC.

When you have your dump, just drag and drop your file on my HPUnlocker tool and it will create a new file. It will add "_unlocked" to the name of your locked file.

Just program the new file on your bios IC.

This unlocker should work on all Elite, EliteBook, ProBook and maybe some other series HP laptops.

For those of you who need to unlock large amounts of laptops, I recommend adding a registry entry:

Computer\HKEY_CLASSES_ROOT\*\shell\HPUnlocker\command

Then modify that string adding

"C:\*location-of-exe*\HPUnlocker.exe" "%1"

This way you just need to right click your locked file and select HPUnlocker.

If there are any issues, please do let me know so I can improve this tool.

All Elitebooks, Probooks and zbooks which are up to ninth generation which should be up to year 2018, like 840 G5, are supported. Newer models are not supported (yet atleast).

No Pavilions or other trash is supported

-----------------------------------------------------------------

Re: HP BIOS unlock tool

hi
i download but not execut (Fatal error detected) - Failed to execute script HPUnlocker

Re: HP BIOS unlock tool

Put it directly in C:/ or D:/ directory and don't use spaces or some strange characters in any names. I had the same problem when I had space in folder name (like "locked bios" should be changed to "locked_bios").

I can't really fix that problem because I usually don't write computer programs so I don't know much about such problems.

I will try to fix it one day but I have some other BIOS unlocking projects right now.

Re: HP BIOS unlock tool

Just used it and works fine.

Did you put HPUnlocker.exe in C:\ or D:\ directory? If your directory has spaces or maybe some strange letters in it, it will give the error you wrote as I wrote before.
