Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.
Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,... -
Hi, I hope some one has some advice for me. I searched the forums but didn't see anything relevant. I acquired two identical Dell 9010 Mid Tower computers from a business office upgrade (they were going to throw them out). Both of them have the same motherboard (00F82W). One of them works flawlessly. The other one had a corrupted BIOS. I tried flashing numerous main BIOS and EC files from the internet, but none of them worked. I decided to copy the main BIOS and EC from the working 9010 computer and successfully flashed the corrupted BIOS. This got the computer able to boot again and run norm...04-23-2025, 04:30 PM -
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... -
⚠️ Not a Rescue BIOS. Flash at Your Own Risk. ⚠️
This is not A17.
This is not listed on Dell's support site.
This is an unreleased internal firmware revision recovered from a university loaner Latitude E6530... and it possibly bricked the system it came from.
It is from the 8 MB Winbond W25Q64 chip. Could be nothing burger but given the anomalies this is a very interesting firmware dump.
Firmware collectors and reverse engineers might find this useful, It contains certs, modules, and DXE drivers not present in A17. This is likely...
