I posted this same problem earlier I am just hoping to get a little more input: I purchased an R4i Gold 3DS last month with my 3DS. I put Wood 1.41 on the card and everything seemed to be working fine. I downloaded the new firmware update (2.2.0-4) for the card. I copied the NDSi file to the root of the card and began my update. The screen goes black and starts the update. I get to the screen that tells me to press A to continue. I hit A and where it says Card Check on the lower screen it says Fail in green text. I get a red message that says reinsert the card and try again. Yet doing so, nothing works. I have tried the same thing on a DS Lite with the NDSL 2.2.0-4 update and get the same error. What I am asking I believe there is something wrong with the card but dwtechz.com who I bought it from keeps telling me nothing is wrong and I would need to pay return shipping to have them fix it which I think is insane.
