I have been using it in my ds lite for a while and just got the XL with v1.4U. In the main dsi menu it says no card is inserted. The only way I can get it to work is if I hold the card in (slot 1) just a little, and it plays just fine (shows Danny phantom icon and everything). If I release pressure, it freezes whatever game I'm playing. I have tried it with official Nintendo games and it doesn't have this problem.

Any help is appreciated as I am desperate to get my m3i zero to work. I flashed it the day I got it and it has worked fine in my lite, except the occasional time it isn't detected. I got the card from Kick Gaming about four and a half months ago. I have tried using scotch tape to add thickness to it, but it didn't work.

Thanks again,
Ken

 

Yeah, its probably the contacts just not touching the DSi contacts. Try tape or paper or something.
