How to rollback BIOS

[Brian412]

Hi, I recently bought an Omen desktop.

The computer sometimes would not boot up and just give me a black screen with beeping sounds (about once every 10-15 boot ups or so... not too often) so I tried updating the BIOS.

CPU is i7-8700

GPU is RTX 2080

16gb DDR4 RAM, OS installed in an 256gb SSD + 2tb HDD storage.

The system ID is 84FD, and the new BIOS revision is F.11

Unfortunately I don't recall what the version was before the update.

Anyway, I only found out later that BIOS updates aren't generally recommended unless specifically required. I'm not sure if the BIOS update fixed the occasional booting problem because that only happened once in a while.

Furthermore, I think the update must have changed the computer's fan profile because now the GPU's temp goes up way higher than it used to, and the fan won't kick in as it used to, causing it to throttle.

I tried using the rollback method as instructed on HP's website (holding windows+B while booting to enter the BIOS update feature). I went through the full process as instructed, but the BIOS version is still F.11 (it went through the process, but the rollback did not work.)

I'm not sure what to do at this point. I want to go back to my original BIOS version and deal with the boot up issue some other way, but I can't even roll back. Now I'm stuck with this new BIOS and I can't even game on it without the GPU throttling and crashing.

Any help would be greatly appreciated!

Update:

I tried entering the UEFI manager screen by pressing ESC during start up.

There was an option to rollback BIOS (it turns out that the original version was F.05), but when I choose this option, I get a failure message telling me that the BIOS sig file cannot be accessed.
