install ios236 (which get all permissions whithout overwriting any system files, don't know if tthere's an offline installer, but one should be easy to make).OK i tried both booting the IOS directly from the SD Card and from NUS and both return the same thing
NAND CREATEFILE - (-102) PERMISSION DENIED
error! installer returned error code. (-1)
if now you use ios 236 instead of 36 for dop-mii it will have all right reserved you can think of, and still all installed system files will be as if installed with nintendo's update system. your preloadr should still function since no real system file is overwritten with ios236. when finished, youcan uninstall ios236 just as you like it doesn't really do anything except getting you without too many risks install system files without network requirements or full functioning system.
