Sorry for bring back this question again. I couldn't brick my DS lite and Acekard2i with Love plus + or Inasuma3 but my friend told me that AK2i is bricked on DSi system only. Did my friend told me correct?
From what I'm to understand, it only 'bricks' the AK2i (and/or 2.1?) when used with certain MicroSDHCs.
MicroSDs should be fine and supposedly so are MicroSDHCs formatted to FAT16 (Normally FAT32 is used).
The Acekard can be fixed by re-flashing it with the 1.4 or 1.4.1 update (DSlite version), but you must have another Flashcart (any type).
