Well, I recently succesfully downgraded my n3ds and barely got to also "Succesfully" instal rxTools' emuNAND. After that, I said, well I think i'm gonna unlinked them, sounded like a good idea to me. Then I downloaded TinyFormat, and started the process, after the process ended, I just started my emuNAND normally. Then the screen when you turn on your 3DS came out, and followed the instructions, but when I got to the 3D screen checking, I noticed the 3D was not working, it just looked like super ghosting, but just one screen turned on. I really did not cared about it and moved on with the process, then when i finished with it, I decided to update my console, and now, whenever I want to start emuNAND mode, the screen goes black! What can I do to fix this whithout having to do all the emuNAND-formatting-and-what-not process?
