      It is not working, computer rebooted 2-3 times and displayed the message:

      The bios has recovered its identity data from the Embedded Controller due to data mismatch

      So still asks for password when entering the bios. Also the CT Number you posted is from the battery, the System Board CT Number is PTLGT00WBJQ0AE​, could it be related?


      Thanks!

          Exact same problem than before, I get a black screen at first boot so F10 does not work. Then it reboots 2 times and displays the message I posted on #3. I have checked CRC32 after flashing to be sure the patched BIOS was written correctly to the chip.


          Thanks!

              Same problem than with the 2 previous unlocked BIOS. I begin to think that HP has implemented some additional security measure on G11 series so when it detects a modified BIOS automatically restores from the EC. I can't find another HP G11 thread on the forum so I can't know for sure.

              Thank you!

                  I can't risk damaging the laptop, I don't even know where the EC is located on this particular model. And because nobody on this forum has still unlocked a G11, there is no guarantee to have this issue solved even if I disassemble the entire laptop and find the chip to extract the EC content.

                  If there is no alternative I still have to think what I'll do.


                  Nevertheless, I am very grateful for all the help. Thank you all!

                    I am wondering if my problem with the BIOS auto recovering its data is related with Sure Start Gen4:

                    Q: What kind of attacks does HP Sure Start Gen4
                    protect against?
                    A: HP Sure Start protects against any unauthorized
                    changes to the BIOS code or
                    BIOS settings, both for the
                    boot time code and the runtime code. These capabilities
                    protect you from a variety of different attacks, including
                    new BIOS attacks that may arise in the future.
                    https://www.badcaps.net/download/?id=ab2f3d79

                    I have a BCU dump of my BIOS settings, some of these may be relevant:

                    Sure Start BIOS Settings Protection
                    *Disable
                    Enable

                    Sure Start Secure Boot Keys Protection
                    Disable
                    *Enable

                    Enhanced HP Firmware Runtime Intrusion Prevention and Detection
                    Disable
                    *Enable

                    Sure Start Security Event Boot Notification
                    Time out after 15 seconds
                    *Require Acknowledgment

                    Sure Start Security Event Policy
                    Log Event Only
                    *Log Event and notify user
                    Log Event and power off system

                    SureStart Production Mode
                    Disable
                    *Enable

                    Also this laptop has an AMD processor with these features set on the BIOS:

                    AMD PSP Permanently Update FW Anti Rollback Security Level
                    *Do Nothing
                    On Next Boot

                    AMD PSP FW Anti Rollback Factory Security Level
                    1

                    AMD PSP FW Security Level
                    4

                    AMD PSP FW Anti Rollback Security Level
                    1
                    HP Sure Start Gen6+ is able to recover the entire AMD Secure
                    Processor subsystem using a copy of AMD Secure Processor
                    firmware stored within the HP Endpoint Security Controller isolated
                    non-volatile memory with no additional dependencies.​
                    https://h20195.www2.hp.com/v2/GetDoc...e=4AA7-6645ENW (page 15)

                    "BIOS Settings Protection" is disabled but "Production Mode" is enabled... Any expert can confirm? I attach my complete dump. Thanks!

                                          I am looking for experienced BIOS modders who can help analyze or unlock the BIOS of my Acer Nitro Lite 16 NL16-71G.

                                          [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,...

                                          LG All-in-One 22V240 BIOS Password Locked - Unlock Key Hint Number Z5DD4808 - Need Help
                                          by marcolinha
                                          Hello,

                                          I need help unlocking the BIOS password on my LG All-in-One 22V240.
                                          Model: LG All-in-One 22V240
                                          Background: I received this PC as a gift when I was a child. I left
                                          it unused for years after upgrading to a better machine. Now I want
                                          to give it a new life by installing Linux, but I cannot format it
                                          because of this BIOS password lock. I have no idea who set the
                                          password or when.

                                          Important: The Unlock Key Hint Number changes every boot (dynamic).
                                          Examples of hint numbers I have seen:
                                          - Z5DD4808
                                          - C649CBC7
                                          ...

                                          Hello everyone. I bought a laptop and it has a bios lock.

                                          HP EliteBook 845 G11
                                          Serial: 5CG4320HMB
                                          System board ID: 8C6E
                                          Current Bios version: W82 Ver. 01.01.05 05/15/2024

                                          Because of the cover error in can't install Windows and make a backup of the current Bios.

                                          I have attached pictures of the several screens that pop up or I can access.

                                          If I use the last QR code (The big one) this is what is displayed:

                                          Hi guys,

                                          If someone would be able to provide some expertise, I'd be very grateful.

                                          BIOS Corruption - Cause
                                          So I managed to corrupt my machine by installing linux and enrolling custom secure boot keys. I did choose to enroll the Microsoft keys as well, to prevent any potential bricking due to 3rd party drivers from HP being signed with those keys.
                                          After doing that, and rebooting(it did boot, powerLED, fanspin etc.), the laptop did not give any video output on the LCD or video connectors. I think I was able to get in BIOS and trigger the beeper by pressing ESC....
