I bought 2 R4i 3DS rts (R4i gold 3DS) few months ago from "Dwtechz.com" they worked great, but now one of the cards says this: "An error has occurred please turn off the dsi". both dsi are 1.4.5u, and wood4 1.57 , they are revision C they never online and the other flashcard still works in both. So did the card just die? or is there any work around this error? Thanks in advance!
