I have 2ds with cfw on it and when I'm trying to move my files from 4 gb sd card to 64 one I have a black screen. I tried many ways to make it work by removing some files or using some programs to drag files to sd card but it wont work. I changed format of the card to Fat32 so its not a problem, card also work when I put it in my 2ds with no files on it, so I thing that the problem comes from cfw files. Is ther any way to reinstal this homebrew on new card, I dont mind loosing files on older one but it will be the best option tu just make it run as it was on this bigger card. Sorry for my English and I hope you will be able to help me.
