Hello, so the 3ds i own, (you know the one in the post i have where my sd card got corrupted) i got it from one of my friends who has a new 2ds xl which he liked it and didn't want his new 3ds xl anymore, so he gave it to me which he said i could keep. however, it has a nintendo network id that is from my friend and it has cfw and badges in it, my friend now has a new network id in his new 2ds xl and he knows about hshop and GYTB. so he doesnt care about the network id on his old one anymore and i asked him permission if i could remove it from the 3ds he gave me, he said yes, but how do i remove it? i want to remove it so i can make (is it still possible to create a nintendo network id in 2024?) and use my own network id, but keep the badges and games in it? he has cfw in his old one he gave me.
