    Try this instead - you just need to reset security settings to default after you get into bios.

      Re: HP BIOS unlock tool

      Hi everyone, quick question: I'd like to avoid to desolder chip, since laptop si still under warranty for 6 months. For that, I'd like to dump EPROM with a clip (may not work, of course, since chip is still soldered).

      First, did you have success with an in-circuit reading? Second, do you know where I can purchase a clip, but not an SO type, but a QFN type? (QFN-8)?

      Thanks !

              First you would want to flash back both original files, just to see if that error disappears.


              let me know if it disappears, then I will try to patch correctly.

                  You will get an error first boot, just ignore it. Go to bios, reset security settings to factory default. If you can restart successfully without any errors then it works. Please let me know.

                      Nice. Do not use the same file on another laptop, you will brick it. Make copies of both chips, just in case and just send the EC file here. It's a bit tricky to get it correct.

                              Nah, this still needs main bios mod only. This should work fine and without needing any messing around with DMI.

                                Excellent friend RethoricalCheese, it worked perfect, but tell me I did it with your v1 tool, and it didn't work, did you do it manually? or I did something wrong thank you very much master.

                                  I did it with my new and improved tool which I have not published yet (because automatic unlocks on newer models is a bit more tricky than it seems. Still needs more improving and testing).
                                  Old tool had a few bugs with certain bios dumps and your bios dump was an example of that.

                                            [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,...

                                            Lenovo ThinkStation P520 BIOS file needed
                                            by Forest79
                                            Hello,

                                            I got a Lenovo ThinkStation P520 (Type 30BF) from a friend, asking me for a repair. Windows 11 offered a firmware upgrade as an optional update, and it failed.
                                            The emergency flash procedure from the hardware manual has also failed. So, I asked an acquaintance with better skills to flash the BIOS directly.

                                            However, the chip (a Macronix MX25L25673GMI-08G) has a size of 32 MB, and the BIOS file from the Lenovo website (extracted with UEFITool) has a little more than 16 MB. Thus, the software my acquaintance used (SiberiaProg v1.45, with a CH341A Programmer)...

                                            BIOS file for ASUS F542UN laptop
                                            by Sebastian Codrean
                                            Hello to all of you! I need help with a BIOS file.
                                            The BIOS chip is fried on my Asus F542UN laptop, and I bought a new chip that needs programming. I have a CH341a programmer but I need a .bin BIOS file. On Asus support page the firmware has another extension, .310 and from reading on this forum I understand that that file is not complete BIOS.
                                            So, in short I need the "complete" BIOS .bin file to flash on the new chip. Another issue is that on back of the case the label says F542UN but on the sticker on the motherboard it's X542UN.

                                            HP Pavilion 15 bc400ns - Complete Black Screen - Only video on live usb

                                            Hello everybody!

                                            To put you in context I recently replaced the battery from my HP Pavilion 15 bc400ns with a used one, everything was going good. The same day, I decided to update the BIOS, everything went good. The thing occurred after I let the battery drain iddling on Windows 11 for the second time to calibrate it that the screen did not turn on again, the computer was on but the screen did not turn, like it would not wake from hibernation. I decided to restart the computer but got no video.

                                            The thing is that I had installed TeamViewer and could log into the computer...
