    Is this the only way ? is there no software that can do this ?

                  ...then try to program this patched dump.
                  If error persist then desolder the chip, program it and solder back.

                                post motherboard model, Service Tag , etc.
                                post the contents of the bios chip even if it is corrupted.

                                          Hi,

                                          Could someone help trying to unlock this BIOS, seems that Dell have changed the layout of new Dell Pro 8FC8 bioses from checking HXD - 4000 bits do not need changing, only 2000. However after FF the section starting from '01000' upto 2000 bits and then soldering the chip back it seems that the microchip on the motherboard is recovering the bios back to original settings after first boot. Has anyone found a way to crack this extra layer of security Dell have implemented? Seems both HP and Dell have upped bios security to match Lenovo by implementing extra measures on a separate...

                                          Dell latitude 5580, motherboard cdp 80 la-e151p

                                          3 amber 3 white blinks. Dell website sais it's problem "bios recovery" and suggested solution "recovery image not found"
                                          (from here https://www.dell.com/support/manuals...e7a&lang=en-us)

                                          I try plugging charger while pressing ctrl+esc, machine turns on, nothing and after 20 seconds it gives 3 amber 3 white blinks again.

                                          Since ssd is replaced and had clean install windows, i've...

                                          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...
