Maybe I'm missing something here? It's happened before....... I read lots of post from people who have downgraded, upgraded, bricked their DS, didn't make NAND backups etc etc. People who are at their wits end and desperate for solutions (been there myself many times). It's almost like a badge of honour that after tens of hours panic people have been able to run X game. So here's my point, why not just spend £60 (approx) and get a Sky3DS+ card? Plays all in - region games, does not matter which firmware version the DS is running so no problems running new games that need V9.xx etc. and it's updatable. It's just easy and stress free. Painless.
