I'm about to help a friend to downgrade two n3DSes one at 10.1 and the other at 10.2. I've seen some chatters about lack of success (or even bricks) from not going from 10.3 to 9.2. Can I get some confirmation from people who have downgraded: is it better to upgrade to 10.3 first, then downgrade to 9.2? Or does it even matter if I downgrade directly from 10.1/10.2 to 9.2?
