I have to be very surprised because no one noticed that the original BIOS uploaded here is total junk.
The user should first learn to correctly read out and compare a BIOS file.
But now he has already overwritten his BIOS, which is very bad because he no longer has a functioning original.
Everything that was patched is based on its bad original BIOS.
And now they say it doesn't work, now it can't.Comment

Blaze Tech and hoaca388 carried out the patch correctly, it just won't help because the initial BIOS arrived here already damaged.
The patching doesn't check the correctness of the original BIOS file.
I just want to make it clear, not that anyone feels insulted.Attached FilesComment

Hello everyone in the community
Dear Sir,

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... -

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...
