          Are you using a clip? Do not rely on it. If not, your backup should always work, try flashing it back. If same symptoms, then check for moved or missing components nearby. Check voltages, start at leg/pad #8 of BIOS chip, should be 1.8v or very close for new laptops. Do not press on bios chip when soldering, it might "squirt" solder to nearby pads if it is too much. I reach the same identical file as hoaca388 when unlocking.

              I checked it too, procedure is correct, I reach an identical file. Desolder and verify that the flashing was good? Try your backup, it should work always.

                        Note that the keyboard to enter the password must be Qwerty US layout (can use an external keyboard via USB 2.0 port). For uppercase letters, use the Capslock key.

                          I stand corrected Sir... Just tried with an external US keyboard and code worked perfectly. Thank you for your help, much appreciated.

                                            3 amber 3 white blinks. Dell website sais it's problem "bios recovery" and suggested solution "recovery image not found"

                                            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 Latitude 5400 Chromebook UEFI bios
                                            by jhanra
                                            Hi there masters, recently i got a dell 5400 chromebook and wanted to install windows, i searched the internet and i found out other people also wanting a UEFI bios for this model, i searched there is a R/W legacy, but there are bugs like keyboard/trackpad not working, and hard to install.

                                            so i decided to try to port one, this bios is based on dell 5400 windows version, i am testing this bios for a week now an found only a little to no bug at all in windows 10, or only a minor issue
                                            in windows 11 sound driver compatibility, but overall its ok, for me i can deal with it, 😅😅😅...
