Official R4I- 3DS card

I'm searching for the real R4i-gold 3DS flashcard. I had a clone, and when I updated my 3DS it stopped working.
So I'm searching for the real thing. And i was wondering if it worked on an 3DS with the newest update.Thanks :D

Updates are designed to block flashcards use , Be warned and a ware next time.Maybe someone here ?... with the knowledge of unblocking it could help you, Sorry but all i know. But don't have a 3DS to know how to unblock.
