I have an R4i. The website of the maker is R4i SDXC. After updating the NDSi to v 1.4.4 (mistake, I know), the r4 didn't work anymore. So i went to the website and lo and behold, they have an update for it already. I downloaded the RAR file , unzipped it and put onto the SD card. I put it in another DS lite and reflashed it (ran the program). Now the card doesn't work on either the DSi or DS lite. Any suggestions to fix this?
