So I removed the emunand partition of my Original 4GB SD Card. formatted my SD Card with the DOS command "format G: /fs:FAT32 /p:2" (that should zero the card's data?) placed the GW 3.1.1 launcher.dat on the SD Card. I then turned on my O3DS XL. (running 6.2 nand) I then used the web exploit to get into gateway mode. Held L so I'm fully in gateway mode. (rather than the auto passthrough mode? Also tried without holding L just to see. Same results.) Pressed boot gateway mode. Black Screen. I know my SD card is fine. I know my Gateway is fine. If I do the same with a SD card that has emunand, it boots to emunand fine. I just can't get into sysnand with gateway mode. I tried on my N3DS XL also and it's giving the same black screen. What am I doing wrong? Shouldn't Gateway mode work with sysnand? **Edit. I just did the Diagnostic Test. FPGA Test = OK! SPI Test = OK! SPI Read Test = OK! SD Test = FAT32 Definitely am lost as why this isn't working.
