Yeah thats because i want to upgrade, and if someone else use my console and they update i want to keep the cw, and i don't like the update messages xDThe main reason you switch to b9s is because it goes into a deeper part of the 3ds's bootrom which is boot11.A9lh is only using the arm9 bootrom which isn't supported anymore with luma.Using a older luma on a future higher fw can run into issues.
Ok it say that, so i think I'm done, so now i can update right? (sorry for keep asking this so many times haha)Turn off the 3ds, then turn it on while holding select. If you see Luma 8.1 menu, it was successful
