Ok so i was softmodding screwed up my xbox and got error 21(who dos'nt) and i figured "Whatever, ill just get a boot disk and restore it." Only wen i did i accidently went to config magic and pressed "Unlock Harddrive," (Which i now know is bad) and got error 5. So i now have to figure out a way to lock it once more. My question is what do i do from here? And is there a way to re-lock it without taking out the HDD or using a modchip?
