I have cfw installed on my 3ds and downloaded the payload or whatever and set my version to the target 3ds without cfw. The guide I'm using (Which everyone seems to use) said this was required.
Not really understanding your position. You have a CFW 3DS and you're using that to install the haxx save so that you can use it on a non-CFW 3DS?
If that's the case, sure, it should work. Just be sure to have the correct payload from smea's HBL site on the root of the SD Card (make sure it's ropbin) as well as the boot.3dsx. Beware tho, booting Oot3dhax on OFW 11.0 will not be 100% successful, it may take multiple tries.
