Critical Thunderbolt Firmware Update fails to install on X1 Carbon 6th Gen

I have an X1 Carbon 6th Gen laptop (Type 20KH). The firmware update mentioned in the following link fails to install:



When I try to update using Lenovo Vantage, it fails with error code 0x207.

When I try to install the firmware package manually, it reports error 0x430000 4390912 and pops a dialog box saying it couldn't find a suitable bin file.


Here are the files mentioned in the update notice that I used for the manual attempt. Note that the driver package install went fine. The problem was with the firmware package install.
