There doesn't seem to be a clear-cut guide anywhere on how to do this, so I'm really lost. I have Win32DiskImager open, and I have my 3DS hooked up to my PC via the special SD card adapter, but when I try to write my backup back to the 3DS, W32DI just says "An error occurred when attempting to get the device's geometry. Error 1: Incorrect function." I've tried two different USB SD card readers, I've tried writing it when the 3DS is on a black screen (since it's bricked), I've tried writing it when it has the bootrom error from being connected to my PC, and nothing is working. So what am I supposed to do?
