Today I have already unlocked several laptops of this model, but the problem is only with this one. Previously, I left the BIOS file from the ISSI chip, add one from Winbond 256 to the archive. I've already tried everything I can.

Hello. help me please. I have a HP 850 g5 with a BIOS password. There was also added fingerprint unlocking. I took a dump to unlock it, ran it through the HP Unlock tool, but it didn’t remove the password. Then I tried the same thing through HP Unlocker - also nothing. I tried to do the same with the chip winbond 256 - the message about the possibility of unlocking with a finger disappeared, but the code was never deleted. Help me please. Here I give you a dump.

Make a bios backup

You are not making these solution clearly, I want you to show me which string in the bios file contains the password, and I want to know how to used updated bios file and the dump locked file to compare and remove the password, just want to know how to do it in all laptop models, thanks, am waiting for your response great engineers.

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

NEW multitool and unlocker added .

Hi all,

I answer myself: I had simply chosen the wrong chip; for an EliteBook 840 G1, you must operate on the “Micron N25Q128A” chip.
I was able to unlock the computer with RCunlocker.

Thanks

[Robert_75012]

The laptop serial number of my HP EliteBook 840 G1 is "5CG5072KBY"
Thanks
