    Hi, sorry for the late response. Work and college.
    Yes. I am new to this whole bios patching situation in itself but I am giving it a go nevertheless. I realize that I may posted on the wrong topic. My mistakes.

      Type: 20L6-SDR213
      Serial No: PF-14H8HB
      The BIOS is locked. I performed two BIOS dumps, and both were verified.
      The chip is a W25Q128JVSQ, and I used a CH341A programmer. I then patched it, wrote it to the IC, read it back, and confirmed the file was written correctly.
      I proceeded to boot the laptop, but there was no display. The buttons light up, a melody plays through the speakers, and then it shuts down.
      I restored the original BIOS, and it locked again, but this time the screen turns on and it prompts for F1.
      What could be the issue?

      I had the same issue and the same BIOS chip. I believe it depends on BIOS version. However here is how I unlocked mine:

      1. Make backup of original BIOS... do not patch this one.
      2. Find factory image for T480 and patch! I used this one (https://www.badcaps.net/forum/showthread.php?t=79414​)
      3. Use patched factory image to remove SVP as per instructions for autopatcher tool
      4. Flash original BIOS

      Hope it helps

        Activation of Management Engine after exchange Z590 chipset - ASUS PRIME Z590M-PLUS
        by DynaxSC
        Hi, i have an ASUS PRIME Z590M-PLUS board, which had an shorted Z590 chipset. I have succesfully exchanged the chipset to a factory new one, however there is a serious problem with the Intel Management Engine (later on: ME) not beeing activated after the chipset device replacement.

        For lower chipset families (on ASUS boards) it worked to program the oldest bios version into the SPI rom, and the bios had activated the Management Engine itself by default - there was a message on the screen prior booting - "BIOS is updating Management Engine ..... . Do not shut down to prevent...

        Is unlocking UEFI worth the hassle? (Surface Pro 4)
        by CronaxFD
        Hey guys,

        Bought myself Surface Pro 4 tablet today on a local craigslist-type website.
        I've seen that UEFI was password protected and of course the seller forgot the password, but decided to buy it anyway.
        Really needed such a tablet to use with RomRaider to do some logging/tuning on my car.
        It has secure boot turned off and boots from USB, so I've formatted SSD and have done clean win10 install.

        Works fine, but wanted to ask, are there any real security risks associated with UEFI settings on Surface (remote access etc.)?

        From what I've...

        Intel NUC NUC6i3SYH UEFI Update went wrong
        by S70rm7r00p3r
        Hi guys.

        I am very new to this business and i have some questions. Maybe someone can help me further.

        I have a 2015 Intel NUC NUC6i3SYH and for some internet and office the computer works perfectly. Lately it has been bugging me a bit on and off. Then I saw there is a UEFI update from Intel and I thought if I put it on, the problems might be gone, but unfortunately the update didn't go through. The screen stayed black and after waiting for a while nothing happened, I had to pull the plug at some point. Of course, the NUC then failed to boot!
