Can't Update BIOS to 2.32 on T460p laptop

2020-11-06, 23:05 PM

I have been trying to update the BIOS on my T460p laptop. But every time I do so I get the error message box:

 

Secure RollBack prevention is enabled.

If you downgrade the BIOS please disable Secure RollBack prevention by a BIOS Setup.

 

I find this odd as I currently have BIOS version 2.31 installed and I am upgrading to version 2.32. So I am not downgrading my BIOS.

 

What is going wrong here?

 

Thanks for any help you can give.

I have the same issue.

I removed Secure RollBack prevention and upgraded.

 

Release date read by linux kernel is odd:

 

LENOVO 20FWCTO1WW/20FWCTO1WW, BIOS R07ET92W (2.32 ) 07/28/2019

Confirmed, I disabled rollback protection, and then the upgrade to 2.32 worked fine for me as well on T460p
