All of our Elitebooks are unable to update their BIOS version to 1.33 from the BIOS update screen.
Steps to reproduce:
Turn on machine
Press ESC to open boot menu
Select BIOS Menu
Select Update System BIOS
Select Check HP.com for BIOS Updates
Update to 1.33
After the update downloads, an error screen appears stating that the BIOS was unable to flash due to a signature or image error. HP Business support stated this was a known issue, but was unable to provide any more information. We are looking to get a timeline for an updated BIOS or to see if HP will roll-back the most recent available BIOS to 1.29.
For further background, downloading the BIOS from the website and then installing it via the EXE does work, however this isn't a solution for us as it requires admin rights, which our end-users do not have.
