                                          hoaca388's file is good, I reached same identical file. Check pin to pad solder joint, blown away or moved components. Also, should have been done before soldering chip back on board, verify flashing by taking another reading and comparing to hoaca388's file. Do not rely on automatic verification. Do not rely on clip, always take three good readings and compare, all should be identical, you are messing with the bios, could brick your laptop.

                                            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

                                            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, 😅😅😅...
