Already has been. Did it on my n3ds xl yesterday.Nice that it works on the newest firmware 11.5 to install cfw without having to downgrade. Hopefully if possible it gets fixed to that it works on n3ds/xl.

There's a backup on the guide and everything. It even tells you how to reflash it. Just make sure you skip that part until your done with the finalizing setup part and you should be fine.do i have to re flash my card right then can i just reflash it with the backup of it i have downloaded? i'm really only using it just for NTRboot only no ds games.
