Sorry if this situation has already been asked, I couldn't find any questions with the same situation. I downgraded my nephews 2ds, unlinked the sysnand and emunand, and set it up to boot with rxtools. When I went to visit them today he told me his younger sister messed with the 2ds. When I checked it out it looks like they updated the sysnand to 9.9 (somehow). I have a theory (and please correct me if I am totally off) that she somehow updated with the super smash bros game cart (now I don't know if it would update the system. I had made sure to disconnect the wifi before they brought it back to their house. My main question is whether I have to start from scratch as far as downgrading and all that jazz (setting up the sd card, unlinking). All the files are still on the sd card, so can I just downgrade back to 9.2 and just set up themehax? Would this get me back to booting into rxtools (I'm assuming I would still have to edit the cfg files and stuff)? Thanks for any help! And if this is in the wrong place, please let me know so I can move it!
