    Search for your device thread or make your own, upload your both files and someone will help you.

          Here's your Unlocked file, in the first boot go to bios menu and disable security options (Default).
          If the password still present upload your main bios, it could be 16MB or 32MB.

              You should program the 2 Unlocked files together and follow the steps that I said before.

                Re: HP BIOS unlock tool

                I just want to thank you for all the info in this thread.
                I successfully removed the BIOS admin password on my HP Elitebook 840 G3 with HPUnlocker and a CH341A (with 3.3v mod) and NeoProgrammer v2.2.0.10 (and a heat gun).
                The Winbond 25Q128FVPQ was the chip to unlock.
                fyi, 'CH341A Programmer v1.30' could not read the chip properly, wheras NeoProgrammer worked perfectly.

                        Re: HP BIOS unlock tool

                        Hi,just tried to unlock my hp 840G5 Bios with thetool from the first page, but it doesn't worked. As there are two IC's which belongsto the BIOS, I'm not sure if I did it with the right one. So question first, is the large 32MB the right one and if yes, is somebody able to do the unlock of my attached one?

                                      I had a similar problem with a 435 g8 and hoaca888 did some magic with the dumps and finally it worked.
