can you be precise with your problem?
you mean it doesn't load?
you can't even get into the flash cart interface?
or?


is your dsi using 1.4 firmware?
if yes, you need to flash your ak2i with the 1.4 patch/fix

 

I turn on my dsi, I start my acekard and there is a loading screen & i can't get past it, I have a game on it.. I don't know what to do to fix it.. & i also installed the latest akaio loader & there is no change

 

If you have 1.4 firmware on the dsi (heck, even if you dont) try:

and see if official firmware for the AK2i works.

 

Where did you buy it from? Have you checked if it is fake or not?
