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
