unable to downgrade BIOS firmware

Hi

 

I am unable to downgrade BIOS FW on my elitebook 745g2.

Reason for downgrade I posted in another topic > wakeup from sleep issue:

https://h30434.www3.hp.com/t5/Business-Notebooks/system-unable-to-wakeup-from-sleep-after-new-BIOS-f...

 

Anyway my queestion is why there is no posibility to downgrade BIOS ?

 

 

I tried to update BIOS from WIndows 7 installer also  from USB EFI... and everytime i got message that image did not pass validation...

 

 

Curios is that  BIOS update is only working  with latest 1.44 FW version.

Even when I download and try one step older FW, i got stucked.

 

Any idea please ?

 

Thank you

 

A.
