ThinkPad X1 Tablet TPM firmware won't update

I'm unable o update the TPM firmware in an X1 Tablet (model type 20GG003UUK).

 

The firmware update utility reports:

  1. TPM manufacturer: Infinion
  2. Firmware Version: 6.40
  3. Spec Version: 1.2

 

When I perform the update it says it is updating to 6.43. It appears to work, in that it says it is doing the flash, the tablet reboots, but afterwards, when I run the utility again, it remains on 6.40. Here's the log from the update...

 

[2018/7/12 16:26:51] TpmUpdt.exe version 1.0.0.0
OS = Windows 10 64bit
Checking TPM status.
TpmFwChk TpmStatus: 1
TPM Manufacturer: Infineon
Current TPM Firmware Version: 6.40
New Firmware Version: 6.43
AC adapter/Battery check....OK.

TPM FW Flashing....TPM FW Flash completed.

 

I'm running this from an admin account using 'run as administrator' on Windows 10 Pro 1803.

 

I'm doing this because of the advisory here:

https://support.lenovo.com/gb/en/product_security/len-15552

 

Can someone assist with getting this updated?

What version of BIOS is on your tablet?

You need BIOS version 1.76 or later

I updated to 1.79, then the TPM firmware also updated.
