I followed the 3ds Guide to hack my 3ds. Everything worked fine but I decide too install a bigger SD card. I just copy/paste the data from one SD card to the other. Now when I turn on the 3ds, it have a black screen. I have to turn it on without the sd card and then put it on to work. I tried deleting the ...extdata/00000000/0000008f folder and didn't work. Any idea how to fix this? Note: I don't know much of this but I think I have sysnand (not emunand). Also I deleted (format) my old SD card. Any help will be appreciated.
