Okay I have a one year old r4i sdhc which just stopped working recentely. (I think because i put the wrong firmware on it). i tried going on the site on the r4i itself, downloaded it and put it on my sd card but nothing works. i tried all the different firmwares on the site. i even tried to reformat my sd card and tried it on another sd card. but still no. i even tried to play a normal ds game and it works. heres a picture of my r4i http://www.nintendo-ds-roms.com/img/flash/R4i-SDHC-WiFi.jpg thx guys for the help. very appreciated.
