Get Any R4 Cart Working On 3DS [11.2 - 11.6 CFW]

Can anyone help me r4 not showing up on 3ds (cfw) home menu. Are these time bombs?, do I have the right files ? : r/flashcarts

If I do a standard factory reset on a hacked (homebrewed) 3DS, will I still be able to use the homebrew, or will it mess it up and require setting up again?
