ThinkPad P14s Gen5 AMD bios mod

[stallonh]

I have a ThinkPad P14s Gen5 AMD and want to use an SSD in the WWAN interface. During the process, I used a CH341A to dump the BIOS file, but I couldn't open the .bin file with UEFITool. Can anyone tell me what might be causing this? I've uploaded some images and the .bin file. Some users on other forums mentioned needing a 1.8V adapter card—will using a 1.8V adapter prevent this error when dumping the file?

The chip is 1.8V so yes, use an adapter. There might be another chip on the board 256Mb , the 128Mb chip might be the recovery bios not sure.
