I have two 3DSs, one on 10.6 with a SKY3DS+, the other on 9.2 with CFW. I'd like to use the 9.2 one to extract a header so I can put it on my SKY3DS+. As I understand it, I need to have Gateway launcher.dat on the SD root and then scan the QR code using Cubic Ninja. I put the launcher.dat (and only that, right?) from the Gateway website on the SD root, and tried to scan the QR. Every time I try, an error occurs causing Cubic Ninja to close, and then the system resets. I'm positive I'm scanning the right region, and I've tried the launcher.dat from both the GW 3.4 "Ultra" and 3.7.1-BETA "Ultra". No difference. I've also tried it using an installed cia of Cubic Ninja from within CFW and with a .3DS ROM on the SKY3DS+ not in CFW. Am I doing something stupid?
