Hy guys. I'm new here trying to troubleshoot some issues. I just got my R4i gold plus 3DS and managed to install custom firmware on my old 3DS. None of the tutorials online mention that I have to upload any firmware to the micro SD card that is inserted in to the R4i. But I couldn't find any firmware that would work with the micro SD card. All I keep getting is a black screen then a white screen flashes then goes back to black.
