Nintendo have just released an update for the 3ds console that blocks many flash kits. The update comes with 3ds recording and playing.The acekard 2i, R4i-sdhc have been blocked.
Nintendo 3DS 3.0.0-5 Compatible Cards:
R4i Gold 3DS

Regardless, I recommend that you do not update your 3DS until manufacturers have fixes for the new 3DS 3.0.0-5 firmware ready.
