So a while ago i was trying to download some hacks for my 2ds. Everything was going well until I used fat 32 to format my sd card and forgot to save it any where else. From them to now i kinda forget which hack i was installing but im pretty sure it was cfw, anyways now whenever i boot up my 2ds without the sd card the screen does nothing and the blue led flashes on then off. When i put in the sd card the screen and led turn on but the screen reads "An error has occurred: Failed to mount SD. Press any button to shut down" I am trying so many ways to try to fix it but cant find anything and would REALLY appreciate some help! Thanks to anyone who trys
