help me please. after my sister borrowed my 3ds it won't go to cfw anymore. just black screen if you try to run cfw. i don't know why and i'm not sure what's happening but i notice that the title manager is gone . i think my sister accidentally deleted the title manager and some other games. because some game was gone also the title manager. could be this the cause of everything? my friend made my 3ds to cfw so i don't really know what to do now please help guys!
