    I followed exactly this volinakis guide and it's 90% accurate.
    I must write 00s on position 3. not FF because with FFs I got Error 2204 :System configuration data is invaid.
    Just an observation...

    Big thanks, volinakis!
    thank you for the precision of the 00

      Here is clear EC dump, you just need to program your EC chip (nuvoton) with Vertyanov programmer) and after that to fill all information like serial number etc..If you can't fill dmi block by Lenovo maintenance utility, here is adresses of these blocks
      Model name located at 0005C000

      SN,type and board number located at 00058000
      I don't have a Vertyanov programmer.
      Is it possible to add or change the boot order in the locked BIOS?
      The machine I have is fine, except it will only boot from the SSD; USB is locked out, so it can't be reloaded.

            unlocked KBC bin (Intel platform)


            for your information, password is stored bewteen address 0x5E000 - 0x5E200. I'm not sure if it is similar for other models. You can erase it with 0xFF manually also. 0xFF stands for empty memory byte

                      You will need an SPI programmer to make a full backup.

                        Should I buy a Lenovo Thinkpad E495 with bios password?
                        by RMDUiFT
                        Good day. I apologize if I posted this in the wrong topic. I saw somebody selling a Thinkpad E495 with a Ryzen 3500U CPU near me. In the pictures the laptop is running windows 10. I contacted the seller and asked a few questions about upgradability and if it has a bios password on it. He confirmed it has a bios password. I searched through the forum, I found a guide regarding removing the bios password using the autopatcher, I also found a thread with the e495 where people requested help with unlocking the bios password.

                        I have a few questions:
                        • If I would buy this laptop and have

                        Thinkpad P14s Gen 4, BIOS Supervisor Password
                        by badzymandiaz
                        I have a laptop that was purchased second-hand, and I am able to boot Windows on and extract the BIOS dump (ONLY the BIOS region, I was unable to dump anything else due to an FCERR I received trying to dump the other regions) and use normally. However, because the BIOS is locked with a supervisor password, I am unable to use anything else except for Windows, and it has also disabled some hardware features of the laptop itself, such as the fingerprinting module, etc. that I really do wish to use.

                        I have been digging around for nearly 2 weeks trying to find any mention of the same model...

                        [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,...

                        Need Clean BIOS/EC Bin File for Lenovo ThinkPad Yoga 11e - Stuck with 0275 Error CMS

                        Hello everyone,

                        I am attempting a repair on a Lenovo ThinkPad Yoga 11e that is currently stuck at boot with the error: "0275 error CMS" even after setup new bios battery and will not allow me to enter the BIOS/Setup.

                        This is a critical issue that I believe requires flashing the BIOS chip directly using a programmer (e.g., CH341A/RT809H), as standard software updates or resets are not possible.

                        I have opened the laptop and identified the main BIOS chip...
