I've restarted my ds, formatted the sd card twice(and the ds), tried with a different sd card, check the payload(ver 11.3.0.36-U), renamed it to otherapp.bin, checked for file extensions, and reinstalled homebrew also. All of the files are in the right place (boot.3dsx, 3ds folder, soundhax folder, and the otherapp.bin on the root of the sd card). When I try to boot up homebrew it freezes on a blue screen. Someone please help.
