Ok, I loaded my NAND backup, and now I'm back on stock, and I totally freaked out when I saw an error message appear when I opened friend list.
It was just a prompt telling me to update to use it, and when I did, it let me use it haha.
I have one 3DS, and it is not banned, I have Boot9strap on it, I have never cheated, I've had spotpass off since December, and I have no custom CIAs installed.
