I've succesfully downgraded my New3dsXL 9.9 to 9.2 and install Reinand & updated it to 10.6. It took 6 hours to get through but it worked well. I've used these two guides: But I have a problem. I didn't start the procedure with formatting my old system. So my Nintendo ID came all the way to my EmuNand. I formatted SysNand along with the tutorial, so it isn't linked there anymore. Now I can't access EShop in EmuNand to update my games. Should I format EmuNand too? If I format it, will I lose this autoboot Emunand? How can I unlink Nintendo ID and link it again in EmuNand? It gives Error code 022-2634 when I try to enter the shop. Thanks..
