Ok so I finish installing the a9lh onto my o3ds xl and so far i am pretty impress with it and I am considering converting my gateway ready n3ds xl to A9lh since some of my game suffer from slow down when running from my gateway card. However, I got some question. I read the guide of course already but didn't see much difference beside the part where when you downgrade the emunand to 2.1. It stated n3ds xl WILL brick the emunamd but didn't say exactly how to unbrick it before continuing.
