Just bought the gateway 3ds from realhotstuff I downloaded the latest firmware 2.1 My 3ds is 4.5.0-10u. I put the correct files onto my micro sd and sd cards But whenever I try to run the blue card installer, I get an error forcing me to restart my 3ds. I have looked around and people suggest using the dstwo, which I have, but same error I tried a different micro sd card, same issue. Any advice? I've used an 8gb sandisk microsd and a. 32gb gskill micro sd My system is for sure on 4.5 I'm formatting the cards on fat32 I've a been trying for the past 3 hours, I even formatted my 3ds.
