If the HD cable unlocks the options, then how do you change the option if the screen is still scrambled with the cable in? Does this make sense to anyone?
Even if you enabled 480p, the MS Dash will always display in 480i, for this very reason.
If you used the two triggers, joypad trick to enable 480p on the dash, you can use the same trick to disable it as well.
So really, the situation you described is nearly impossible and/or easy to fix.
