In my enthusiasm to upgrade the WLAN to a non-whitelisted card, I've messed up my BIOS and need help recovering. I found a F.0D version with whitelisting removed on this website and flashed my laptop to it. The flash programming and verification were reported as successful by Windows and the machine restarted but would not boot. CapsLock flashes slowly and the WiFi button is a steady amber. Since I had read about this possibility, I tried to reboot into Recovery mode by holding down the Windows+B while pressing the power button; same result. I created a USB stick with the HP UEFI Support Environment tool and copied the relevant .bin and .sig file from the original F.0D BIOS file to the Hewlett-Packward\BIOS\Current folder on the USB stick, inserted it into the laptop, held down Windows+B and powered on; same result. Now I'm panicking. Any thoughts on other things to try? Thanks.
