So presently my sister was using my DSi and upgraded the firmware for me. I don't know what verison this is [is it still 1.4?] and I don't know how to check it, but now my AK2i is not working. I recently upgraded to AKAIO 1.5.1 - about a week ago - and it was working fine. I was also thinking that it would bypass the DSi's block. Oh, and if anyone's interested, here's what my DSi says when I boot up my AK2i: "An error has occured. Press and hold the power button to turn the system off. Please see the Nintendo DSi Operations Manual for help troubleshooting." I'm going on a trip for my March vacation, and I'd really like a quick fix for this. Anyone know anything? EDIT : I've looked around and heard about this 'DP' update thing, and I do have extra DS's at hand. Is it just put it on the AK2i and press 'a'? Or is it more complicated than that?
