My REAL Ace kard2i doesn't work!?

probably try a different sd card?

Tried that too.. -_-

it could probably be bricked then, try this: http://gbatemp.net/t218103-updated-n00b-guide-to-setting-up-your-acekard#11 . go to section 11, and look at the unbricking part

"Bricked" huh? Man...Just like my psp a year ago. Okay, I'll check it out.
