so i have a old 3ds xl that has a9lh luma install i brought a n3ds a few weeks ago so i did the dsiware exploit successfully where it involved system transfer so now my n3ds is also a9lh and has luma so know i dont longer need my old 3ds xl and i want to give it to a friend but my old 3ds still has the friend code that im now using on my n3ds since i did that system transfer i was wonder if theres a way to remove the friend code on my old 3ds xl and make it have a new one?
