Hey, I have been using an original R4 for a few years, with a 1GB Kingston MicroSD card. Has been working 100% for a long time. Today I followed this tutorial. After I was done I loaded it up into my launch model DS, and got SD/TF Card Error. So I format the card, load it up again and the same error. Format again, put the old R4 firmware on there and got the same error. The SD card is perfectly readable in the computer and other devices, so I'm guessing my R4 is just dead? Is there something I'm missing here? Thanks.
