    Thinkpad p1 gen1 unbrick

    Hello everyone!

    After An BIOS update the support for special characters got supposedly removed, so I got locked out of the BIOS, because my supervisor password contained a special character
    I am now trying to flash BIOS files on my BIOS chip with a T48 programmer and the minipro software (as I am running Linux), which works so far, except it seems that I don't have the correct files.

    Laptop Model: ThinkPad p1 gen1
    Motherboard: LPM-1 MB 17870-1 448 0DY04 0011
    BIOS Chip (supposedly): MX25L25673G@SOIC8
    CPU: i7-8850H
    GPU: Nvidia P2000

    Help would be appreciated, thanks in advance

    attached: firmware pulled from chip, i.e. bricked bios

              So far I've been a silent reader, but now I need your help

              I bought a laptop. The seller said the bios was locked. I was looking for a way to remove this ban.
              I then got the CH341A and pulled the corresponding files from here https://www.badcaps.net/forum/troubl...evices-and-ele...
              The laptop was brought in with a BIOS problem and a password. After reading the dump, the information was damaged. I ask for help in the BIOS with a clean ME region. Motherboard 213035-1. Serial number: PW+04e998, Type number: 21c3-0016ge

              🛠️ 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

              Should I buy a Lenovo Thinkpad E495 with bios password?
              by RMDUiFT
              Good day. I apologize if I posted this in the wrong topic. I saw somebody selling a Thinkpad E495 with a Ryzen 3500U CPU near me. In the pictures the laptop is running windows 10. I contacted the seller and asked a few questions about upgradability and if it has a bios password on it. He confirmed it has a bios password. I searched through the forum, I found a guide regarding removing the bios password using the autopatcher, I also found a thread with the e495 where people requested help with unlocking the bios password.

              I have a few questions:
