    Here is something interesting:

    "Inside the EC’s own MCU flash (again, not in the external EC SPI we patched — lives on the Nuvoton/ITE microcontroller itself).

    -than I think I found the responsable chip. NUVOTON NPCX499HA tells you anything ?-

    Yes — that’s your Embedded Controller (EC).

    The Nuvoton NPCX499HA is a high-end EC MCU HP uses in newer EliteBooks to handle:
    • Keyboard, battery, fan control
    • Power sequencing
    • Firmware verification for HP Sure Start
    • Storing/triggering the BIOS recovery payload

    Here’s the key point:

      I'm sorry, I'm done with this laptop. Doesn't matter what dump I flash on those chips, it gets reverted. Now I've patched 3 Chips and still recovered. Where the hell does the BIOS copy stais? I have no idea and to be honest I lost my patience...I have now the clean BIOS main, Clean EC, and clean 1MB that has the HP sure on it. Still my password returned. It's not about the dump you throw on it anymore... it's about finding the chip that keeps a copy of the original BIOS and force it back to the main and EC chips . I'll search for further information in the future . Thanks for all the help I've...

        I did try every variants available here. Only one doesn't POST, but those that post are immediately reverted to the locked BIOS. I need to find a third Chip (usually smaller than BIOS and EC chips) that trigger that fu*king recovery. I did found a 1MB Chip that GPT says it might be responsible and patched it for me. Now I have to flash all three chips back and try again. If the recovery is still triggered I just give up......

          Hey there. Back from my vacation, armed with a bunch of new BIOS chips 💪🏻 Tried both files first one starts the laptop but the password comes back, second doesn't work at all. Tried the first one only the EC file with a main file that I've done using HP recovery, started but same sh*t happened, some information on the screen telling me that the original BIOS file was recovered from the embedded memory because someone tempered with the BIOS and...the password came back. I don't know...this embedded memory controller is the EC chip or is another chip hiding on the MB? If you want to try tempering...

            You mean, that part should be replaced with FF or 00? For the moment I've gave up, due to lack of time and, after writing and rewriting the BIOS chip 4-5 times...it said enough and burned... I'm waiting for an order of 10 chips from AliExpress but it will take some time. Keep it touch 🤘🏻🖖🏻...

              Hello guys! Found some troubling info about the HP security from 2024 onward:
              HP Endpoint Security Controller 2024
              Attacks against PC firmware are on the rise. Unfortunately, protecting the PC BIOS and other critical firmware is often not seen as a priority. HP addresses this with our Endpoint Security Controller (ESC), a dedicated chip that validates the integrity of the BIOS and other firmware to enhance the security of every HP business-class PC. The ESC validates that the firmware is not infected by malware before the CPU is allowed to boot. If any corruption has been detected, it will...

                Tried another way. Basically I've replaced the entire ME Reg part of the BIOS with info from a Firmware recovery file from the HP site. After more than one hour everything was done 👍🏻 Laptop starts and...informed me about the mismatched information and that it's doing a quick recovery ... after two restarts, the password is there of course 😖😖😖 How the h*LL can I stop it from doing this sh*t recovery? I didn't find any cmos battery on this model, the power is out long enough....How does it remember?😢😢😢

                  Unfortunately doesn't work 😔 Some error appeared telling me that the BIOS makes some recovery from the embedded memory due to mismatch ID information...only one option and that was to click "OK" , after 2 minutes the laptop restarted and the password is still there. This is so annoying 😖😖😖 Anyway, thank you for helping!...

                    Hello everyone! I have this Laptop with a locked BIOS 😔 I've tried unlocking the EC file but it's "Missing unlockable content" so...main BIOS, split in 2x16Mb files, RCUnlocker said it's unlocked, spits a *_unlocked.bin file, reunite the flies in a 32Mb file but... nothing changed. Verified with CMD certutil -hashfile but it's the same file as the original 🤷🏻 what's up with that? Can someone please help? 🙏🏻 Thank you 🙏🏻

                      KippyKip, you're a savior !!! This worked like a CHARM on my EliteBook 865 G9 ) After entering all the data for the BIOS, waited for the count down to get to 1 and accept my information but SURPRIZE ) "Cirrus discrete bla bla error" and was stuck like that for more than two days ( But than i've found this post and everything WORKED GREAT !!! Only one thing, deactivating Secure Boot it's a MUST not a Might. If you can update the zip file with Bootx64.efi would be great for beginners like me would be the BEST. Anyway, whoever get the error about Cirrus Discrete, should use with 100%...

                        Hello everyone,
                        I have a Elitebook 865 G9 with a locked BIOS 😕
                        I've read both chips, made photos with the location of each Chip. The orig.bin file is the BIOS Chip from the front side of the board where the RAM Sticks are and scoring.bin is from the backside of the board. I don't know where the password reside so I've read both of them. If anyone can help please 🙏🏻

                          Hello Guys,
                          I also have a problem with my P53 and it's as follows:
                          Unsoldered the BIOS Chip, read+read+read...4 times, checked with certutil CMD, everything was fine. Used the autopacher on the bin file, write it on the Chip and again 4 times read and checked with certutil, again everything was fine. Resoldered the Chip on the MB, 15-20 minutes to put the laptop back together 😭 I hate this models... Plugged in and ... nothing. The power button light comes on, stays like that for 2-3 seconds, shuts down and repeat. After the second shutdown, it comes back on but this time blinking...

                            Hoaca388 you're a badass!!! Worked like a charm, except "system is booting in MPM" error with count down but, after inserting all the data in BIOS, everything works great 👍🏻 👍🏻 👍🏻 I hate this 32MB BIOS bin files 😭 But I love the fact that people like you, and others here on badcaps, help with open heart, people like me and others that struggle!!! You have my eternal respect 🙏🏻🙏🏻🙏🏻...

                              Hello my friend! Worked like a charm!!! But still... something strange happens. When I try to reset the security system (I do that always after unlocking a 16MB BIOS) the password is required. I can't set a new password because it's asking me for the old one. Anyway, the BIOS works and I can access it, but can't change anything in the security tab. For me that's good enough 👍🏻👍🏻👍🏻...
