Dell e5530 can't update BIOS

Question

Hi all!
I am trying to update BIOS of e5530, currently installed A02 version. Downloaded the latest one A15, it gives me the normal precautions window, after that window with compare between my current one A02 and the new one A15, after that filling bar window with "Preparing to update", when it is full, it restarts laptop with no change made to BIOS.
I tried to install lower version first A03, but with the same result. With or without antivirus software installed, the outcome is the same.
Windows 7 64 bit.
Oddly enough the laptop has a sticker of Core i5 vPro, but the BIOS is non vPro. (Trying to install vPro BIOS, result of message telling me I should use non vPro BIOS).
Thanks for the help!

Yes, downloaded the latest version -A15. It wasn't working as I described, so I decided to try older version A03, as I have pretty old one installed A02. Still the same problem.

I just made FreeDos usb stick, with the BIOS exe file, downloaded from official Dell page 5530A15.exe, booted from USB, ran the executable file, went through the process, just to find out it's doing the same thing - it just shows 'preparing to update" filling bar, after that it restarts, without affecting BIOS in any way.

:emotion-2: You did downloaded the latest BIOS from the Dell website ? www.dell.com/.../drivers

This is how it looks like when I'm trying
- to update with the smallest step possible A02 to A03
- Under Dos, as I saw several posts suggesting doing it through it
The result is "preparing to update" bar, restart of the laptop without any changes made to BIOS.
Someone help please?

Is there an administrative password on the BIOS?
