Hm. By default, they're locked, right?
See, I'm trying to install a modchip in my console. It's been a drawn out process and at some point during the whole thing, the screw hole on my console's motherboard that holds the chip in place became stripped. So, I was going to go ahead and install the chip in my friend's XBox and then just swap our hard drives. Seeing as how I can't get the modchip to work in my console, though, there's no way I can unlock it.
