he people, I did it last night...I installed a9lh on my main 3DS and all went fine, yeah. But I did a System-Transfer before to my "rescue"-3DS to save all my data, cause of an brick. So the problem is now, that I can only login via the rescue-system but not with my new a9lh 3DS. So what i can do? Wait a week and do a system-transfer again, the way back? Or can I unlink the NNID from the rescure-system and login in the new system easily?
