        The patch won't work if the bios version is latest. use this bin flash both it won't work if you only flash the main you should Flash Both.
        first boot press f10 apply factory defaults and restart, 2nd boot reset security settings to defaults and exit.
        use BCU and put your original DMI.
        frequently asked questions:
        can i use this to my HP EliteBook 840 14 inch G10 - Yes
        I've read through all the guides/documentation that I've been directed to, but I cannot figure out how to eliminate the bios password on this laptop and the seller claims they do not have any record of what the password is.

        I've run the utility but it just sajus"Wrong chip. Try reading and unlocking 16mb chip!"

        I cannot install new OS as it stands. Not sure what I'm doing wrong here. Thanks in advance!

          For the moment no solution is clear, however some laptops with certain version have found a final solution, just look for rex98 in some posts.

          post your bios here maybe you find your unlock

            Great. Thanks!

            How can I take a dump of my bios without being able to access it directly?

              It is too early in the morning and I'm not thinking clearly. I will get a dump directly via ch341a and then post here once I've got a good dump. Thanks again!

                  Hi, after applying post 120 the password prompts for F9, F11 and F12 were disabled, but unfortunately not F10. After flashing both chips (and re-reading and verifying against supplied bins) the HP Elitebook 840 G10 went through its normal few reboots, but before I got the opportunity to get to a point where I could press F10 to set factory defaults, I was presented with "BIOS Identity Data Recovered: The BIOS has recovered its identity from the Embedded Controller due to data mismatch"

                  Anyway, please see attached dumps. Hopefully they can help identify a resolution

                          Yes, also re-read both main and EC to verify again against bins. I have tried another two times today with same result.

                          After the "Recovery" screen I also tried just reflashing the EC. Password still required for F10

                                  Managed to solve the issue. I modified your EC.bin provided in post # 120 and cleared NVRAM ActiveRegn.

                                  This time, instead of the EC recovery screen, it threw the "Entering MPM" and was able to F10.

                                  Password now gone. You are a legend rex98.

                                  Probably best to verify attached before use.

                                      No worries, obviously had to add back standard DMI settings, plus MAC, plus Cirrus Discrete Amp Calibration Data. Best to take a full BCU config dump first to be safe.
                                      I'll repeat on another 840 G10 in the next few days.

                                            [REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock
                                            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,...

                                            Hello,

                                            I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
                                            So I thought it was a Bios problem.
                                            I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V....

                                            Dell Latitude 7420 BIOS Unlock Gone Wrong
                                            by Jeff'sTech
                                            Hello everyone.

                                            I have come here with a rather specific question. I was given a Dell Latitude 7420 laptop with a busted screen, and wanted to see if I could refurbish it into my daily driver. I wanted to experiment and see if a 2-in-1 display would work as the chassis of the laptop and 2-in-1 7420 looked identical. I threw in the display and my hypothesis was correct, however, I was greeted with a locked BIOS and since I didn't know the password, I figured I'd try to unlock it somehow. I bought one of those POGO pin probe things for my CH341A programmer so I could read and make...

                                            Hi sirs. please help
                                            Dell Inspiron 5775 bios locked "Unlock Setup fail"


                                            After generating the Password Recovery code, I go to the “Security” tab - “Locked Settings” - it says “Unlock Settings? I tried many wrong passwords and it shows an error to unlock settings [ Press any key ].
                                            What I did:
                                            I read the bios dump.
                                            Downloaded the bios update to 1.6.0 from the official Dell website, extracted the dump from it, updated the bios, but the problem persisted. Please help me to solve the problem....

                                            ASUS TP500LA BIOS request/repair/merge?
                                            by jbonavita
                                            Hi, my laptop wont boot at all
                                            With original bios no POST, only LED lights
                                            With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
                                            Some issues
                                            A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
                                            B- If updated from 500LN version 203 to 300, the battery stops being recognized

                                            Things I tried

                                            1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...
