i had the same problem, i just delete with fbi and found the qr from one website that i don't remember, but you can download it with 3dnus. here the list:http://3dbrew.org/wiki/Title_list
oh that suck, i just use hans for take Magearna with qr, but maybe i don't use online for this, maybe i will be safe, i just use a lot of reboot for be sure and use mk7 for nnid+multiplayer
