Summary of BIOS Whitelist Removal Problem


Problem:
I am attempting to remove the WWAN card whitelist from my Lenovo ThinkPad T560.
Initial Findings:

• My current BIOS version is N1KET58W (1.45).
• I have a CH341A programmer and have successfully created two full backups of my BIOS.
• I have the ability to use command-line tools on a Linux machine.

Troubleshooting Steps & Conclusions:

• I attempted to use several automated and manual patching methods on my N1KET58W (1.45) BIOS, including using hex strings. These attempts all failed.
• I concluded that the

I'm trying to extract a flashable bios file(ch341a) from the lenovo bios executable download. I have tried the instructions from this site https://starkeblog.com/lenovo/uefi/2...pdate-exe.html, which are not working. According to those instructions, after issuing the command it should create an \app folder, inside which, I should find a newly created "7wcn38ww.exe" file. I should then be able to extract that using 7zip and find my .FD file.

The trouble I'm having is that I'm not getting the newly...

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....

Recently I used the official Lenovo bios updater software on my ThinkBook 13s G3 ACN (20YA0005GE). The updating process failed and I got a black screen after powering the device. Of course I did not make an own backup before using the Lenovo bios updater.

I bought a CH341A programmer and was able to make a connection to the chip while it is still soldered on board. But I did not realise that the chip was a 16MB size and selected the wrong size (8Mbit / 1 MByte) before reading the content of my chip. So the dump I did before erasing the chip is only 1MByte big. I fear that I lost...

I'm working on a Lenovo LOQ 15APH8, Serial# MP2L9MAV. I want to flash a new BIOS onto it, but I'm also trying to learn this process for my own enrichment and professional development.

I was watching some tutorials, copying the serial info blocks from the old bios to a new bios. Before that though, they use innoextract on the Lenovo .exe. I downloaded Innoextract v1.9 but it tells me my .exe is not a supported inno setup installer(see screenshot). So if I unpack this using 7zip, I do get a .ROM file, but according to my tutorials, I'm looking for a .FD file.

How can...
