i also have a 3ds with 3.0.0.5 and Acekard 2i.. i tried upgrading the card with dsxl 1.4e, but it doesnt work.. i used ak2ifw_update_3ds30_DSi143_onDSi_and_DSXL_and3DS.nds but when i try running the file it says i have to reboot.. it does not let me start the upgrade...
and before anyone asks who that robot is, it's actually from an episode of the donkey kong cartoon, where dk ends up accidentally switching bodies with it, and there's a banger song in that episode that you may have heard before in a thread
