Heh, but if you don't like downgrading and double NANDs, prepare for the torture, because only the final setup is going to be 1 NAND updated to the latest version. But in the meantime, you downgraded to 9.2, then setup an emuNAND, downgraded it to 2.1, sent it to sysNAND, went back to 9.2 then went back to the latest version
Don't confuse lengthy and hard though. It's annoying to do but you don't have to do it in one streak, and the guide (google Plailect's guide if interested) is really detailed (you can read it without following it if you want, just to confirm that if you ever decide to follow it, you can't reasonably be lost).
