Thanks Nexus. But now I got another problem. stupid me, i install big brain using wup installer and now it occupy haxchi icon. So i deleted the big brain but haxchi wont start and error "nintendo id bla bla" and require me to install big brain. I download it again but error "105-3687" when installing. It led me here but i cant delete .tik coz cannot access "storage_slc" with error "failed to retrieve directory listing". what should I do? kinda desperate now..
