HP Omen 15 BIOS crashed

[Chris98762]

Windows 11 made a BIOS upgrade of my HP Omen dh0012ng. After a reboot the screen stayed black, no HP logo appeared. I made all the suggested solutions on the HP Support website, nothing helped.

I tried to downgrade the BIOS to a previous version via USB stick.

Only the latest version creates a boot stick, that loads BIOS again on the notebook and flashes it, but in the end the screen stays black again. I downloaded nearly all previous versions of BIOS that are shown on the HP support site and created boot sticks with these setups but no one does anything when I try to boot from them.

Can someone help me to downgrade the crashed BIOS?

The notebook is out of guarantee but was working great, there is no hardware problem at all.

• If it doesn’t work, try the same process but replace Windows + B with Windows + V keys.

Follow On-Screen Instructions: If the HP BIOS Update screen appears, follow the on-screen instructions to recover the BIOS.

Reflash BIOS Using HP's BIOS Utility

Download BIOS Files:

Hello Kuroi_Kenshi,

I have done all of your suggested steps but it didn't help.

With the BIOS Recovery USB drive the BIOS got installed and flashed, but after the reboot the boot logo ist still not displayed and the screen is just black again.

Because of that I can't follow your last steps to flash BIOS manually. When I press ESC nothing happens at all and the screen stays black.

@Chris9876567890, I see you were interacting with @Kuroi_Kenshi however, he's away for now and I'd love to help you out.

Thanks for the quick follow-up — I know how frustrating it is to stare at a blank screen when your system was running just fine before.

Since the BIOS recovery completes but the screen stays dark afterward, it does sound like the flash may not be taking properly, or there’s a mismatch in the BIOS version for your specific board revision.

Here’s what I recommend next:

Try Forced BIOS Recovery with Internal Display Reset:

Fully power off the notebook (press and hold power for 15+ seconds).

Plug in the BIOS recovery USB with the latest working BIOS version.

Now hold Windows + B (or Windows + V, depending on model), then press and hold Power for 2–3 seconds.

Release the Power button but keep holding Windows + B/V for up to 40 seconds.

If the fan spins up or you hear beeps, the system is trying to enter recovery—even if the screen stays black. Leave it alone for up to 5 minutes.

Hope this helps! 

Take care, and have an amazing day!

@Zoey7886, thanks for your advice.

If I try your steps with Win + B, then the Omen boots from the BIOS recovery stick, loads and flashes the BIOS, reboots and then stays black again, even after +5 minutes left alone.

If I use Win + V, then the screen "CMOS Reset (502)" appears and the notebook reboots after pressing Enter. The screen then also stays black after +5 minutes.
