      I'd like to send you my original .bin file. Could you edit it completely for me?

      We have two layers here:

      3e320 and 3f320 (see images)

      I've already scoured the internet with the help of AI
      And there are many different methods for what needs to be zeroed out.​

        Thank you James Bond, I have done what you say from 1 to 11 and I get error 20, when I ask SVOD4 Support they say "arm not answer" maybe there is differences on the circuit between T14 GEN 3- NM-E441 and T14 GEN 4-NM-F261 on the NPCX997 circuit on the schematic although they look similar although I see someone able to read it on NM-F261

          Sorry I forgot to say that I can only get that error reading when I select motherboard, if I select Nuvoton and config I can't detect anything but when I select NM-F261 motherboard and read ID it will give me ERROR 20

            As soon as I reset the three numbers in the 3e420 line to zero, the supervisor password is activated again and I can't access the BIOS.

            What exactly did you do to make it work for you?​

                GREAT! Thanks Maxpower3.
                Now I can edit all the data in the BIOS.
                I still get the following messages at startup:​

                    If you can send a reading after the clean dump eprom on the forum, it will be useful to everyone, thank you.

                      OK, I'll read through the thread today and do it later and report back.

                      Sharing the latest version of Lenovo Golden Key I found to change DMI information such as serial number, MTM, UUID. Run the U1 application and create a bootable USB. It may show an older version upon making the usb. Restart the program and it will update the USB to the next version available. For some reason the updater program

                          OK, just ignore step 2 and then click on "Update" and it will work.

                              And B0 must start with 8S I believe. I marked in parentheses


                              Did you clean the dump before rewriting the numbers?
                              It's better to start with a clean dump.
                              Otherwise you risk having errors.
                              Use the eeprom operations function.(5)

                                      I've now tried 3.5.75, and it shows me that the system is locked.

                                      At least I've gotten a few fewer error messages.​

                                          Everything worked now!
