I get that 'failed to connect' with any method, hahaWith this method, I can boot into the CFW, however, after ~10 seconds, whenever I scroll over icons in the home screen, banners fail to load and doing anything besides scrolling causes a freeze, and of course, It fails to connect. I know my IP is correct as whenever I run run.bat, the WiFi light on the 3DS blinks.
Any method will end up with the same results by the way: NAND image on sector 1 of the SD card.
Mine is simply the easiest.
BTW, yeah my 3DS's wifi light blinks everytime I run the command too.
