This may be stupid but i'll go for it. So, say you have a 3DS. Its firmware 9.2. Then say you have another 3DS. Its firmware 9.9. Is it possible to extract the nand of the 9.2 3DS and replace the nand in the 9.9 3DS? Then you could format and you would be on that firmware? This sounds like a somewhat reasonable way to get onto a CFW-compatable firmware, right?
