So for the past 3 weeks I've messed up doing the DSiWare downgrade twice. Once where the game refused to copy at all and the other where the system transfer suddenly had a error. I've followed the steps properly and it happened still. Am I supposed to put the source 3DS' SD card on the Target 3DS after it prompts me to copy the DSiWare game? Because I did it before and it just did the error. I've only did the 10.7 downgrade so I'm not so sure how to do this.
