Alright so I just bought a used 2DS XL and I modded it using the 3DShacksguide with seedminer and all that good stuff. Did everything perfectly. It's been working fine since I did all that. Since then I've been finishing up my Pokemon X game and adding pokemon with PKSM. Now I'm ready to move onto my Pokemon Ultra Moon (bought in store actual game card) and as soon as I insert the card both screens go black. Nothing I can do to stop it while it's inserted. As soon as I take it out it goes back to normal? Every other game card I have pops up just fine when I put it in. I understand there could be an issue with the card itself but it was working fine before I modded the 2DS XL so I'm at a loss here. I checked out the card as well and it looks perfectly fine. I got it for Christmas so it's basically brand new and I have barely touched it since I got it. Only started the story a little bit and then packed it back away until I finished my other game. Is there something else I need to edit or install to get it to work again??
