I don't think it's compatible with a 4 gig Micro SD card, try using a 2 gig or less Micro SD and see what happens.

 

If you don't insert a micro sd into the Acekard it should still show up on your DS menubar with the AK2 icon. Using different firmware isn't going to help you since the card itself isn't recognized to begin with. My guess is that the gold contacts isn't making a good connection. Try wigging the card while it's inside the DSi or wedge something between the label side of the card and the DS to "push" it closer. If that doesn't work ask for a refund.

 

4coolday sent me an email tonight saying they'll swap it out. I think I may just get an r4i sent out and sell whichever one I'm not using at work lol.

 

r4i cards are ak2i clones so if you don't like the ak2i, you'll hate the r4i

 

Yes I do but the team doing it now seems to be keeping up with new firmware. Worth a shot while im waiting on my AK2i.

 

Well, you're entitled to buy whatever card you want but keep in mind that you won't get any support if you run into problems. Nobody here at gbatemp will be willing provide help for a counterfeit/clone like the R4i.

 

I wish I ordered a 16GB now. I went from 2GB to 8GB, thinking that'd be plenty... But now that I can fit some music and several movies on, I really could do with a 16GB, since I've not got much space left.

Oh well.

Oh, and don't get any sort of R4. You may think it's updated quite a lot, but really AKAIO is one of the most updated firmwares, and it's Acekard only. Yeah, okay, you can run AKAIO on some R4s (the Acekard clones) after a long process, but AKAIO 1.5, which is being released soon, will totally block R4s from running it.
