I have a N3dsXL with gateway 3.7.1 Sysnand 9.0.0-20E with time travel hack which makes it possible to launch via ds profile menu Emunand 10.5.0-30E. I want to remove my NNID from it and sell it. I don't care to keep the NNID since I don't have a Wii U or planing to get any other 3ds system. I know that there are 2 options. 1) Format memory 2) Unlink NNID from the settings menu? Couple of questions 1) Will formatting emunand remove the NNID from the system? And will the system be in a state that will work as normal when the other guy takes it? He just needs to create a new NNID? Or do I have to do something else? Sysnand doesn't have option for NNID since I installed time travel on it 2) with Gateway 3.7.1 is the latest update 11.2 supported? Can I just update emunand and sign in NNID and unlink it without any issues or gateway 3.7.1 doesn't support latest update?
