T490s 20NY Update BIOS unattatended does not work

I have updated T490s ECP to 1.12 manually using n2juj14w.exe  works

After reboot I connected to the system requiring updated to 1.51 using psexec and connected as system to simulate SCCM

I attempted to update the system after reboot to 1.51 using winuptp.exe -s for unattended install

The system is stuck at winuptp -s and never completes, I have to end the psexec session

 

Seems like issuing winuptp -s as system through psexec might have a dialog window open waiting for user interaction?

I logged into the system through RDP, opened a command prompt, changed to the flash directory, typed in winuptp -s and a dialog window opened where I can press the next button to proceed with the BIOS update. 

 

This is not unattended, as such we cannot update our fleet of:

T490s/T590/X390/X390Yoga/X1CarbonGen7

All the above systems face the same issue.

 

The affected version of winuptp is 34.0.15

@grunzer,

 

The unattend for the BIOS is not working for some models.  We should be releasing updated versions soon that will address this.

How soon ?  This week ?  Next month ?

 

I can't understate enough how much of a massive headache this is causing our business not being able to automate BIOS updating tasks with these models.

@Rumpole,

 

In the latest BIOS Update Readme which right now is version n2juj16w, it states in the change notes:

--------------------------------------------------------------------------------
CHANGES IN THIS RELEASE
  Version 1.51

[Important updates]
- Update EXE/Readme to support silent installation option.

[New functions or enhancements]
  Nothing

[Problem fixes]
  Nothing

 

and further down:

<1.51>
 UEFI: 1.51 / ECP: 1.12
- [Important] Update EXE/Readme to support silent installation option

<1.51>
 UEFI: 1.51 / ECP: 1.12
- [Important] Update includes a security fix.
- (New) Support for non-Absolute Persistence Module version of UEFI BIOS.
- (New) Support graphic BIOS setup menu.

We also include in the readme the Caution information at the top about if the ECP is on 1.09, you will need to install 1.12 first then update the BIOS to 1.51/1.12.

--------------------------------------------------------------------------------
CAUTION

  If ECP version is 1.09, update ECP to 1.12(n2jur14w) or higher version prior to
  update UEFI BIOS. Otherwise, system may hang in UEFI BIOS updating process.

--------------------------------------------------------------------------------

Is your ECP updated to 1.12? If so, have you downloaded and tested the BIOS n2juj16w package silently?

Re: T490s 20NY Update BIOS unattatended does not work

Hi,

Thanks for updating the README file.  I have seen some interesting behaviour when running the BIOS updates here.  I can confirm that i had already updated to v1.51 and 1.12 as per the below first run of the BIOS update tool that i downloaded a few weeks ago.  This version of the BIOS and corresponding WinFlash versions definately do not support the -s switch.  I just run it again in the past hour to confirm.

 

However with the URL you have linked to, i have downloaded this seemingly "newer" v1.51 BIOS and the winflash tool that comes with that is newer, and allows the BIOS to be updated with the -s switch.  You can see my log file for this below.

@Rumpole,

 

It does appear that they updated the package mid version.  I apologize for the confusion and inconvenience.  I believe that the WinUPTP.exe -s or WinUPTP64.exe -s should work now per the latest revision.

Re: T490s 20NY Update BIOS unattatended does not work

Looks like you are flashing to a version of the BIOS that is the same version already installed?

If I flash with the same version the -s switch does indeed work.

but when I go from 1.49 ECP 1.12 to 1.51 ECP 1.12 this is when I have an issue.

 

Thanks for your responce, I appreciate you are looking at this.

 

Cheers

Re: T490s 20NY Update BIOS unattatended does not work

And now i've just found out that we've received a bunch of T490s's with BIOS version 1.55 !!!  How can these machines come with a newer BIOS out of the factory than i can download from the lenovo web site ? What's going on here Lenovo ?  Where is v1.55 downloadable from, and is this definately the best (newest?) BIOS at the moment to be using ?

(And yes Grunzer, i was reflashing to the same version... That's how i normally apply our custom BIOS logo)
