I've been using my AK2i for about a year without any problems, but the last week when I was playing my rom, it got froze, I turned the DSi off and turned back on. My AK2i didn't load at all, it just show in the top screen a white screen, and in the bottom screen a black screen, and it didn't pass of there. I've formatted my Sandisk micro SD several times, put the lastest Akaio and nothing, it stills the same; no menu, no black screen with "Loading" , no error message, no nothing. I had tried the paper trick and it don't helped either. Also I tried using a older version of Akaio and the Official "firmware", but nothing. The Acekard is detected by the DSi so I don't think that it is a contact problem. It is updated for the 1.4.1U. It is not clone, I think. I've already cheked it. I don't know why it stopped working suddenly. What could be the problem? Is the micro SD the problem or the AK2i? I really need your help. Sorry for my english if there is an ortographic error or something.
