USB Debugging is definitely off. When I go into a command prompt to flash the boot.img, "adb devices" returns no devices. The drivers all seem to be up to date - so how can I flash the boot.img? I can't get into the OS as I get stuck at the white HTC logo boot - soft bricked.
I would normally recommend RUU (http://forum.xda-developers.com/show....php?t=1562890
) to revert to stock firmware and then turn on USB debugging like normal, but I'm worried that your device may still be unlocked (then RUU won't work).
Hold the phone, when you boot into the bootloader, and select "fastboot", can you flash the boot.img that way? (command prompt: "fastboot flash boot boot.img", assuming your command prompt is opened in the same folder as fastboot.exe and your boot.img)
