Answer to "How do I fix my 3DS Error Problem?"Hello. My 3ds xl is giving me the same issue. Turn it on, 10-15 seconds and black screen with an error has occurred message. My wifi card was still plugged in so disconnected and reconnected it but same issue occurs. So I disconnected the wifi card again and kept it out. Now when I turn it on it stays up but when I try to load anything it locks up. Reconnect the wifi card and original issue returns. I think I have a bad wifi card, anyone agree?
