    Asus Zenbook 14X UX3404VA (UX3404_MB) password request

    Hello everyone! I am not looking for a ready-made solution, but I am looking for advice and help to understand the principles. We have a problem: UEFI password. We have a dump from the SPI BIOS (version .204) and an update file from the official website of the same version. In the BIOS region of the original dump, there are two NVRAM areas at the beginning that contain DMI and certificates (and most likely a password). In the BIOS region of the update file, the NVRAM area is only one. By what principle is a ready BIOS region formed from such an update file? When manually deleting the scripts in the HEX editor, I get a shift of 64 bytes to 00D376B0. I tried to use the BIOSUtilities scripts, but unfortunately nothing works, only errors appear in the console.

                  Thank you Legend! But this is a ready-made solution... I will not ask how the password is decrypted from the dump, but I have questions about how to asseble the BIOS region from such an update file? Since this is the first time I am dealing with the update on Raptor Lake and the file structure is not typical for me.

                      This is the bios region I have cut out the extra parts, I'm not good at English so I can't explain more clearly. You can see it with UEFITool.

                              ASUS ZenBook UX480F : need help with cleaning the ME region of my BIOS dump
                              by mkdj
                              Dear all,
                              I have a ASUS ZenBook UX480F with the following symptoms:



                              I suspect it is a BIOS issue. So I decided to try to clean the ME region. I followed the guide on win-raid, and I believe I have done everything correctly. My problem is: when I open the outimage.bin in ME Analyzer, it says that it is Extracted, and not Region, Extracted as it should be. Is it normal, or did I do something not correctly? This is my first experience editing BIOS files.

                              I would appreciate if someone could take time to explain the issue, so that I can learn. But I would...

                              by Nopslide
                              Hello everyone, I come here to tell you my problem regarding the power-on password. It is not a bios reset demand, and i can't have any access to windows. This is the bios and power-on password that is blocking all other things.

                              My Omen 15-dh0052nf purchased second-hand was configured with the bios password upon purchase (very simple password :P ).

                              Having decided to sell it in order to get something more powerful, I reset all BIOS settings and set a blank administrator password. But the power-on password cannot be changed to a blank one so I let the actual password set....

                              The batch from which the password was removed works correctly but... after some time, the BIOS password is set again, I reprogrammed the batch with the removed password, it's ok, there is no password, I set my password, ok, I can enter the BIOS with my password but...
