    Dell Pro 13 Plus PB13250 Bios Unlock

    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 IO chip which hasn't been cracked.... just yet anyway.

    I have attached both the original file and the modified variant that I made which still didn't work. SMDFlea have you got any ideas? If I were to post a bios of another pro 13 plus with the password on and one without the password enabled on the same laptop would that help?

          [REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock
          by zenius
          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,...

          by remizbushka
          Hi sirs. please help
          Dell Inspiron 5775 bios locked "Unlock Setup fail"

          ​
          After generating the Password Recovery code, I go to the “Security” tab - “Locked Settings” - it says “Unlock Settings? I tried many wrong passwords and it shows an error to unlock settings [ Press any key ].
          What I did:
          I read the bios dump.
          Downloaded the bios update to 1.6.0 from the official Dell website, extracted the dump from it, updated the bios, but the problem persisted. Please help me to solve the problem....

          Dell 9010 MT BIOS Update Always Fails
          by mikeybass
          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...

          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...

          by jhanra
          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, 😅😅😅...
