I bought 2 R4i-SDHC 1.4.1 from Shoptemp I was told by the R4i-SDHC.com to send you a request for a new cards do to them being not in working order. I have tried numerous times to upgrade the firmware and everything and they don't want to work. R4i-SDHC.com told me that this was from a bad batch of cards that was released. Can i get replacement cards since i bought them from shoptemp are am I out of luck. Please let me know what information you need and ill send it to you.
