    Dell XPS 15 9520 BIOS Password

    Hi!

    This is my first post over here, and I hope I'm properly following the instructions.

    I recently got a XPS 15 9520 that (sadly) has an admin password, which normally wouldn't be a problem, but this model has support for RAID using the 2 NVMe slots.

    Using bios-pw is sadly not an option since it has an 8FC8 suffix. I tried dumping the BIOS and patching it since I just got a CH341A and a clamp. Sadly, I was not able to properly attach it since I believe the clamp I got is of really bad quality and I have no confidence in my soldering skills. I would greatly appreciate some help unlocking it.

    Model number: Dell XPS 15 9520
    Service Tag: 2L096W3​-8FC8
    motherboard model and revision: hd051/hda51 la-l402p Rev: 1.0 (A00)

    All help will be appreciated.

          [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,...

          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...

          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, 😅😅😅...

          Dell Optiplex 7010 micro bad BIOS flash?
          by mrrubik
          Hi folks,

          I got a Dell Optiplex 7010 micro PC (Exact Model) with 8FC8 BIOS and locked out admin password. I attempted to remove the password by patching the BIOS via info from this thread: https://www.badcaps.net/forum/troubl...ssword-patcher
          After flashing the patched the BIOS, the PC is unresponsive with a solid AMBER power LED (not documented in manual anywhere)

          Steps I took:
          1. Read BIOS with CH341a, verified hash twice
          2. Patched
          ...
