    The ME is corrupt,there`s error messages with ME Analyzer ,and FIT won`t decompile it. Post the unlocked bios that you got from the different macbook

          X270 - Bios flashing help
          by Timeeez
          Hello everyone,

          I am still a beginner and want to learn more about flashing bios. First of all, thank you very much for the tutorials made on this forum it helps a lot.

          Lets get straight to the point. When I try to flash the bios of my Lenovo X270 it restarts several times and always returns to the bios that was there at the beginning. When I get the bios from someone on the forum and write it to the bios chip, I always have the same serial numbers. I have the feeling that the pc is reflashing itself. Where could this come from? How to avoid this problem?

          [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,...

          Lenovo Thinkbook 15 G2 ITL i5 (serial number: MP2BFZEF) bios request
          by Wahaz
          Hello,

          I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
          So I thought it was a Bios problem.
          I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V....

          Flashing ASUS UX51VZ with correct bios
          by Flyview
          Hi!

          Happy to be part of this forum for my first post!

          Short story:
          I believe my dad's UX51VZ has an incorrect bios (v207) for a UX51VZH flashed onto it. I'm not quite sure what the differences are between UX51VZ, UX51VZA, and UX51VZH. The serial number of this machine is D5N0CY845932229 and comes up as a "UX51VZ-DB103P" when checked on this ASUS website. All of the bioses can be found at this ASUS website.

          1) Do I have the correct bios or should it be the v205 for UX51VZ? Is there something I can check inside the machine to make sure?

          HP Pavilion Gaming Laptop 15-ec2523nd - Dimm2 slot disabled after corrupt bios repair? Advice requested.
          by Bloodhoundje
          Hi everyone,

          I have been doing hardware repair as a hobby for some years now and recently decided to learn about repairing laptops as a fun challenge.

          I managed to get my hands on a "HP Pavilion Gaming 15-ec2523nd" notebook that only shows a white power LED and doesnt respond to anything.

          After initial testing I concluded the bios seems to be corrupted since all voltages are normal and there are no shorts. HP has a feature for a bios restore from USB with winkey+B for this model. This did not work.

          I have desoldered the bios chip (GigaDevice...
