I installed cfw on an o3ds successfully then I thought I restored the card as it showed up and let me play ds games off it, but today I went to install cfw on a n3ds XL but when I click on the icon it flashes to a white screen for a few seconds and goes to a black screen and stays like that, I have press home to go back, tried flashing the card using 3ds hacks guide but can’t find the card on the list after holding start on boot, 1 point if you name the card in the pic, 1,000,000 points if you can help me out thank you.
