        I have two t470s laptops. After auto-patch they both do the same: the keyboard lights up and goes out, the power button lights up, after about 30 seconds a strange melody is heard, no display - and that's it.
        I have successfully removed the password on several of T470s's before, but now I am doing it on another computer - maybe different hardware is the reason why it doesn't work anymore. But I don't know what has changed exactly. From software - only Python version, every other thing is the same.
        Both machines are 20JT-SOSM1G (motherboards WIN LIPC PCL10N07803). Numbers: PC-OUFQCT and PC-OUFQDS.
        If I reflash original bios - laptops work but passwords, of course, are present.
        In attachment - original bioses.
        Can somebody please make patched files?

                Hello,
                Last week my T470s stopped booting, with music error 0284 - TCG-compliant functionality-related error (might be the BIOS code validation failure).
                I have made a backup of the Bios, please see attached.

                              Hi there,

                              Could you please fix my BIOS?
                              When I press power button this happens:
                              - ESC and CAPS LOCK blink green
                              - F1 and F4 blink orange
                              Then nothing happens for probably 10-15 seconds, screen is black. Eventually it always reboots and does the same in loop.

                              TYPE: 20JT

                                  Thanks for assisting me and providing a new .bin file, but unfortunately I had no luck, the problem still persists.

                                    Anyone else?

                                          Summary of BIOS Whitelist Removal Problem


                                          Problem:
                                          I am attempting to remove the WWAN card whitelist from my Lenovo ThinkPad T560.
                                          Initial Findings:
                                          • My current BIOS version is N1KET58W (1.45).
                                          • I have a CH341A programmer and have successfully created two full backups of my BIOS.
                                          • I have the ability to use command-line tools on a Linux machine.
                                          Troubleshooting Steps & Conclusions:
                                          • I attempted to use several automated and manual patching methods on my N1KET58W (1.45) BIOS, including using hex strings. These attempts all failed.
                                          • I concluded that the

                                          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...
