So I just got a Japanese N3DS. I kind of lucked out and it shipped on sysNAND version 9.1, so no need to downgrade (wow... Particularly lucky since the N3DS is the one that has the far larger chance of soft-bricks. I wasn't relishing the thought of going through all that.) This means I also have the benefit of a completely clean sysNAND.
Anyway, I was looking at the region swap tutorials and I think I must have originally looked at something completely different because these definitely don't look right. They both want you to use a 4.x system for starters -- and I don't feel very comfortable with the idea of downgrading a N3DS to 4.x... I've already learned the hard way that downgrading mset won't work for software like that either since it has to be updated for the newer firmwares (offsets or whatever, I don't know) and the N3DS has different offsets besides I think.
Is there a method using newer tools? Perhaps some that can run from Homebrew Launcher or CTRBootManager?
