Hi, i have to remove the entire A9LH install from one of my New3DS XL because i sold it and the buyer doesn't want any CFW or other Mods on the consolee. How can i do that without loosing my NNID? First Format the Console, to my knowledge that deletes everything (not a9lh) from the console and if connected to the Internet it unlink the UUID so i can login with it on another console right? Or do i have to do to unlink the UUID from the Console? And the other question is: How do i remove A9LH installed? Is there a delete Option in a tool to do that? If yes which program do i have to use. Are there probably a step by step guide? And my last question is: What should i do first: Format the Console or delete a9lh? Thanks in advice for your help.
