yes i did set it to nand but i get install error when i try to install it dsiware instaling works but not built in softwareDid you set fbi with L and R to "Install title - NAND"?
Not that it should cause errors if you forget to change it from SD mode, but you won't get an icon afterwards...
...oh and by the way NAND apps are only loaded when Home starts, so it's normal for it to not show up as soon as you close FBI!
the error message is to long for me to want to type it out also emunands on lasted verWell, that does it say exactly, and are you sure you're downloading the cia for your version?
You could also uninstall the eShop and do a system update, if that's easier!
