                  Try restarting the laptop, auto patch does not repair laptops, just unlock supervisor password

                      Try the forum autopatch, if it doesn't work post BIOS dump.

                        Paid service asked me to share EC dump for patch. Not to share bios dump. So i shared EC dump here. I cant take the MB dead risk again. If anybody hv 100% solution post here for help.

                            I will repeat for the last time...
                            ThinkPad E14 (20RA, 20RB) is possible to unlock it through DXE drives.

                              Just write clean ITE dump extracted from Lenovo Bios update. All data like serial, uuid will be gone but can be set again with uefi maintenance disc

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.

                                          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...

                                          Dell inspirion 5775 bios "Unlock Setup fail"

                                          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?

                                          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...
