Downgrade my BIOS for OMEN by HP 15-dh0009ne

[Stornyy]

Hello,

My name is Storny, I recently updated my BIOS to version F.48 (the latest one) and now I suffer fps and stutter problems in-game. Now I want to downgrade my BIOS to F.47 or F.46 does not matter I just want to downgrade my BIOS. I tried every single method including the BIOS recovery method and turning off the laptop and holding Windows Key + B and then clicking on power button, but that method did not work for me since all I got was a black screen. Anyways, I downloaded the BIOS version F.47 on a USB drive and tried to boot up the laptop from the USB for it to instantly downgrade BIOS but nothing worked and the laptop just boots to the Login screen :(. All the HP support replies for other people regarding this topic was unhelpful for me and I even tried watching a couple of videos but to no avail. I have an HP Omen 15-dh0009ne as listed above. Anyways I also tried going to the Hardware Diagnostics and clicked on Firmware Management and tried navigating to "BIOS Update -> Select BIOS Image to Apply -> HP_TOOLS -> Hewlett-Packard -> BIOS -> Current -> 0"my serial board number".bin -> Apply update now", when I clicked on Apply update now I received a message saying "Unable to open BIOS Signature File". It basically restricts me from downgrading BIOS. I tried flashing the new BIOS "the one im currently using" using the same Hardware Diagnostics method, and it certainly did work. So now all I want is a way to downgrade my BIOS and bypass the "Unable to open BIOS signature file". Please help me 😞 Thank you!
