I want to first note not a single one of these issues had been happening before I updated to the latest firmware. I first noticed an immediate problem because my 3DS XL would freeze everytime I selected the Mii Maker icon after updating. So I restarted it thinking that would fix it, nothing I did would fix the problem. I was forced to format the SD card as a last resort fix. After formatting it, it then worked again normally as far as I knew.
Now I have even more problems specifically with downloading software more importantly it staying on the system intact. I had been playing everything just fine before this update and had no problems like I am having now with downloaded software just vanishing and becoming corrupt randomly.
For instance I was playing the Bravely Default demo, I had probably put in over 10 hours just leveling and ranking up jobs to mastery. After updating to the latest firmware and being forced to format now the Bravely Default demo does not want to work past the save select screen after being redownloaded. Everytime the game reaches the new game/save select menu an error occurs telling me to turn off the 3DS XL and restart the software again. In doing that, it does not fix the problem and the same error happens at exactly the same spot every single time using up my play time for that demo as well.
I am basically at a loss, hoping maybe someone here has experienced something similar and knows a fix. I tried emailing Nintendo but it seems they haven't mailed back in a while, no telling when I will get a respone back.
All I can do is buy another memory card or send the system in which I really don't want to do considering they both worked perfectly fine before this update. The update process had no problems either to cause this, so I am assuming this either needs to be patched or the update somehow completely screwed my SD card up, so now everything gets corrupted randomly.
I see other people posting about this also but they say its due to Pokemon Bank? Have you guys considered the firmware causing this problem with SD cards. I have not downloaded that yet, I do have Pokemon X though but I am experiencing very similar problems which to me all started happening after the firmware update, I had not done anything different or even put anything different on my 3DS XL except updating to the latest firmware recently which caused all these problems for me..
