I just bought a R4i 3ds which is meant to be compatiable with my DSL but after much hard work it doesn't seem to be working. I'm using a fat32 formatted SDHC card with the latest wood kernel. I have had previous r4 that have worked fine for years. I know how this all works.
Here is some pictures (including what is on my SD card right now): http://imgur.com/a/cR5cc
