Hello, i am having a problem with the console saying the SD card is stuck in write-protection. i can tell you for a fact, the card is not. the slide is at the top and have even tried 2 other SD cards. The other SD cards i have also work fine in another 2DS i have tried. are there any suggestions how how to fix it? i updated the console and formatted it just to see if that would fix it. Thanks

Try to open up and clean the contact pins, they could be dirty and shorting something out.
