I have a DuoX 2GS chip installed and working and I'm trying to flash it. (I installed the chip because the hard drive crashed when the xbox was unmodded.) I can boot to the flashbios screen, or the cromwell, but I can't navigate the menu. I've tried a couple wireless controllers and some aftermarket wired, nothing works. Do I need an original controller, or what? I'd appriciate any help, thanks.
