I have 4 or 5 copies of each of the games that work for soft modding. I bought them years ago when I was modding xboxs. I thought maybe I would lose or break some, and they were super cheap. Maybe I should try selling a few on ebay.
Error 5 means your hard drive isn't locked. If you're xbox is chipped properly, it shouldn't care about that. Are you sure it's not just soft modded?

Your post says enigmah chipped. There is an enigmah video switcher, is there a modchip called enigmah too?
I don't use it on the switch, but there should be a power icon on the upper right. There might also be a "logout" option somewhere that when clicked gives you several power options.
