ThinkPad X1 Carbon 4 Generation (20FC) BIOS update (bootable CD written on USB drive) in Linux

Hello!
I want to update my BIOS. My OS is Red Hat Enterprise Linux.

 

I downloaded the bootable CD ISO file from:
https://pcsupport.lenovo.com/bg/en/products/laptops-and-netbooks/thinkpad-x-series-laptops/thinkpad-...

Then checked the checksum, it is fine.

I used 2 methods with no success:

USB Image Writer,

the method explained here (which worked for my ThinkPad T430, but not for X1 Carbon 4 Ge:neration) https://cloudnull.io/2017/07/x1-bios-update-under-linux/

 

When I boot from the USB drive, a black screen appears and then I am kicked back to the boot device selection menu.

Please, check if the bootable ISO file is actually bootable.

Re: ThinkPad X1 Carbon 4 Generation (20FC) BIOS update (bootable CD written on USB drive) makes noth

The BIOS exe file contains tools and instructions for making a bootable flash drive.  If you have access to a Windows machine or VM you might try that approach instead of manipulating the ISO:

in BIOS I selected Boot, UEFI only,

this way it worked.
