I bought a R4iSDHC silver card in China and it worked for a little but after I added a few new games, the memory card was corrupted and now the card doesn't work. I tried bringing it back to the place I bought it but they're pretending like I didn't buy it from their store and want me to buy one of their cards instead (that's china for you lol). Anyways, I'm trying to figure out how I configure it myself but I'v never done this type of stuff before. I have a R4i SDHC silver card, the website on the box is www.r4sdhc.com. I downloaded the 3DS V4.4.0-10 Upgrade Firmware and English Kernel but I'm not sure what to do now or how to install them. The memory card is completely blank. I have a 3DS with the latest updates. Any help would be great! Thanks.
