So I was stupid the other day and I let this dumbfuck in my grade borrow my hacked 3ds. Since he was so damn thirsty to play ssb4 I get it back and my fucking 3ds is on 10.6. Now, I have a NAND backup that was on 9.2 on my computer (I did it with Gateway).... Is there any possible way to downgrade without hard modding? I feel like I'd brick my 3ds.
