For oothax, he only needs the boot.3dsx. I've used oothax a multitude of times. I know how this works. This is not the same as other entrypoints where you need a payload at the root of the SD card, like steelhax. You're telling him false information.Get the payloads from here. Make sure that it corresponds to the haxxed save and that it's ropbin, not otherapp and drop it in the root of your SD Card.
Use the 10.4 payload since that's what your 3DS actually is atm.
If he doesn't have the payload in his root, he won't be able to launch Homebrew period.
