Hi I bought this DS card which says its compatible with 3DS's but it didn't work. So I tried to update it with the newest firmware of their site (www.r4i3d.com) and put it on a micro SD card. then i put it in my dsi and located the file and tried to update it. it got to a point where it said please cycle power so i turned it off and on again. then the card wouldnt even be detected by the ds. what should i do? how do i unbrick it? please help?
