I have 2 mi box 3's (MDZ-16-AB) one is bricked, one is not, I found a lot of guides using flash drives and going back to an earlier version, is there another option? if not, which tutorial is actually working and the best? for the second one, I just downloaded a bunch of games on retroarch and looking for a controller to play, I have a Xbox 360 wireless adapter for PC, and I'm wondering if it'll work without drivers? (It needs drivers on windows to work.) also last time my pal was over we tried connecting the Xbox one S controller wireless and it did not work (it did detect it on Bluetooth, just didn't pair up), it did work wired though, which wont do it because my couch is pretty far from the box and I don't have a long enough micro usb cable...

Thanks.
