I cannot update BIOS on my ThinkPad L480. After I run winuptp64.exe I complete the wizard. Then system restarts. While booting there is blank screen for a few seconds. Then OS starts but BIOS stays old. Installing BIOS from boot CD doesn't work too.
My actual BIOS version is 1.31 and I'm trying to install BIOS version 1.36. The BIOS was downloaded via Lenovo Update utility. The same problem occured with older BIOS versions: 1.32, 1.33, 1.34, 1.35.
I even created WindowsToGO USB media, boot L480 from it and tried to apply BIOS from there. But the progress was the same. I reset BIOS settings to default but no success.
[2020/1/7 12:58:14] version 30.16
OS = Windows 10 64bit
System BIOS Version -> R0QET54W
Applying BIOS Version -> R0QET58W
AC adapter/Battery check....OK.
BIOS Flashing....BIOS Flash completed.
In the folder where BIOS update files reside there appears filename "null" with this content:
BitLocker Drive Encryption: Configuration Tool version 10.0.18362
Copyright (C) 2013 Microsoft Corporation. All rights reserved.
ERROR: The volume G: could not be opened by BitLocker.
This may be because the volume does not exist, or because it is not a valid
But there is no drive G: on my system, even bitlocker is not enabled on my system. The "null" file appears in the folder after unsuccessfull BIOS update.

Hi Van_Lenovo, thank you for your reply, but you have provided me a standard procedure how to update BIOS. I know how to update BIOS. The main cause why I asked for help is that the standard procedure doesn't work. I need to investigate, why the update process fails and how to solve the problem. That's why I enclosed the logs that my be helpfull.
Of course, I have done all the steps (once again) you have mentioned in your reply, but the result was the same, as expected.
All the best,
