              [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,...

              🛠️ MSI GP75 Leopard MS-17E71 – No Display, Deep BIOS/EC Troubleshooting
              by macabook
              Hello everyone,

              I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
              🧩 Initial Issue
              • Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
              • External display (HDMI) shows
              ...

              [Problem/ Request] Bricked TongFang GK7MRFR BIOS
              by cr4zychriss
              Hello everyone,
              I am requesting urgent assistance to unbrick my laptop, a rebranded TongFang GK7MRFR chassis. The laptop is completely dead following a faulty in-OS EC flash attempt.
              I have successfully used a CH341A programmer and can read/write/verify both flash chips, but using my backups/extractions has failed to restore power. The root cause is likely a corrupted Intel Management Engine (ME) region or an incompatible EC/BIOS pairing. System & Hardware Details

              Dell Pro 13 Plus PB13250 Bios Unlock
              by Akhlz001
              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...

              ASUS Zenbook Pro Duo UX8402ZA BIOS
              by pirati
              Hello everyone,

              I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.

              When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.

              I decided to try flashing a new BIOS, but since I didn’t want to desolder...
