        Edit: @SMDFlea - I did not notice your comment, you've posted while I was processing the bios.

          Yes, I tried this tool and there is no password anymore, but the functions in bios are not active and I can not now use the boot to upload windows 10 with a pen because all functions in bios are not active, I cannot enter them , maybe the tool did something wrong and these functions are inactive and cannot be entered ??

            You can't enter the bios with F10, or your can but all parameters are grayed out, and you can't change any?
            Try to restore bios defaults.

                  I want to add LT4211 4G module to this HP Elitebook 830 G5. Do you think I can do that after using this tool? Will this remove the whitelist from BIOS?

                    Hello Mate,

                    HP ELITEBOOK 830 G5
                    BIOS: sp136471 (https://ftp.hp.com/pub/softpaq/sp136...0/sp136471.exe)
                    Version: 01.18.01 Rev.A
                    Release date: Dec 17, 2021
                    Windows 11 Pro 21H2

                    I have added a WWAN as below:
                    HP lt4211 Gobi 4G Module
                    but, BIOS showing error 703. So far I understand it has something to do with the whitelist. Please, please, please help.

                    Best Regards / Mr. Neo

                      No it does not remove any whitelist. Try over at bios-mods.com

                        Re: HP BIOS unlock tool

                        Is it possible to do a verification of the password data in the BIOS dump? If I load the dump into a hex editor then at which part of the file should I expect to see a password or a cleared password? Are cleared passwords simply marked as 0 at said section of the dump? Essentially what is the algorithm that the tool uses to clear passwords? Knowing this will be helpful in working with dumps from a safety standpoint.

                          Re: HP BIOS unlock tool

                          Hello!

                          I have a HP Probook 650 G4 which sadly has a BIOS administrator password, so I cannot enter BIOS setup. I desoldered the W25Q256 flash from the board, read it (3 times, consistently), modified it via hpunlocker.exe and flashed it back.

                          System starts up, but it is still asking for an administrator password sadly. Any ideas what I might have done wrong or what I might have missed?

                          Files attached are original BIOS, modified BIOS, screenshot from system info.

                          Many thanks in advance!

                            Upload your 16MB chip bios dump.

                              Oh, sorry, seems I did the process on the wrong bios IC? Or do both need to be modified?

                              I attached both original bios dumps. Had to find and desolder the other one... Thanks for your kind support!

                                  So I better revert the 25Q256 back to its original state, I guess?

                                  I can't thank you enough! If this works out, I owe you one. Send me your Paypal address via PM, I'll send you some beer (or at least so you can buy some )

                                    No, leave it as is for now, just flash the 16MB chip with the new file.

                                        Re: HP BIOS unlock tool

                                        I have a HP 840 G1 with a BIOS Administrator password and a User password. I downloaded the firmware to a file but after applying the patch and flashing the firmware back, the Administrator password has removed but the user is still there. As such I am only able to login as Guest user. Although the Guest user does not allow me to clear any other users. The tool has not cleared any BIOS users with password. It would be helpful to know what does the tool actually do and is there a way to clear out users as well as their corresponding passwords from the BIOS?
