Re: Dell Latitude 5520 Bios Password unlock
I checked procedure, identical bins reached. Verify chip again, check pad solder, missing or moved components, clean and re-tin pads. I am not sure what is the form factor of chip, probably wson 8x6. Clean middle pad, sometimes it gets too much solder and sort of wobbles when using hot air.Comment

Hello everyone in the community
Dear Sir,
I need help removing/unlocking the BIOS Service Tag password on my Dell Latitude 5520 laptop.
Problem details:
* Model: Dell Latitude 5520.
* Board ID (from BIOS file): TGL MB 8L 19819-1 (Southpeak15).
* Required Password Code: 3FE2 (BIOS Service Tag Lockout Code).
* Service Tag: (Enter your actual Service Tag from the laptop here)
* BIOS Status: I successfully modded the BIOS file and created FINAL_CLEANED_ME.bin (32MB) with a clean ME region (CSME 15.0), because the original dump was corrupt.... -
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...
