I read the bios again and am attaching it here.
    Hello,
    I had the same problem once with a Dell 5590.
    I also recreated the BIOS with 3 and 6 flashing and then everything worked normally.
    Days later the same 3 and 6 flashes again, I then discovered that the Gigadivece IC itself was defective.
    Then I used a Winbond and everything was fine.
    I would use a new chip or another chip for you.

                        Hi Markus , so its been 24 hours i have changed the chip and flashed the bios that you cleaned for me. There seems to be zero issues. I have disabled UEFI updates as a precaution. Thank you so much for all the help you offered.

                        Also for anyone else who's having bios auto-recovery issues, you should try replacing the bios chip.

                        I will keep using the laptop and if there are any issues, i ll post an update here.

                        Thank you so so much, Markus. You are awesome.

                              Hi all,

                              I have a Dell XPS 7590, for which I need to remove the BIOS password. Can anyone please help me with this? The details about the laptop:

                              Dell XPS 7590
                              ST: D4B1M63
                              MB: couldn't find it (is it on the keyboard side?). I presume it's a LA-H331P
                              Administrative password removal needed

                              Thanks a lot!

                                  Didn't remove the password but did start in factory mode. I noticed that only two bytes were changed in the dump. It's supposed to be like that?

                                    I managed to get a valid password from here: https://bios-pw.org/ , so not needed any more. Thanks!

                                      by zenius
                                      Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

                                      Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...

                                      Dell XPS-15 (9520) Mostly Bricked after common BIOS-Firmware upgrade - Full Repair Log
                                      by Tesla
                                      I have a Dell XPS-15 (9520) with the LA-L402P motherboard. It seems to have bricked itself after a common BIOS-Firmware upgrade. Now, it just shows BIOS screen for a few seconds before turning-itself back Off (and doesn't seem to be fully Posting). I've done these many times before with no problems.

                                      I was hoping to please have my own-thread to work-through this (hopefully successful) repair as a whole. Apart from the possible need to have a BIOS-dump fixed-up, I have a feeling I'm going to have other questions. This includes using my new XGecu-T76 for the first time (should be here...

                                      Hi,

                                      Could someone help trying to unlock this BIOS, seems that Dell have changed the layout of new Dell Pro 8FC8 bioses from checking HXD - 4000 bits do not need changing, only 2000. However after FF the section starting from '01000' upto 2000 bits and then soldering the chip back it seems that the microchip on the motherboard is recovering the bios back to original settings after first boot. Has anyone found a way to crack this extra layer of security Dell have implemented? Seems both HP and Dell have upped bios security to match Lenovo by implementing extra measures on a separate...
