Misc NNID Doubt and formatting.

[Robika]

Hi so I want to do the fieldrunners downgrade on my New 3DS that has My NNID with a lot games I bought and I want to conserve and keep buying games I like. But I have to Format that console with the system transfer.
So my question is do I lose this NNID forever or after the system Transfer downgrade and ARM9LH insltall I can format and vinculate it back to this console and keep using it without losing all I have bought so far?

I had this same question and no one answered me before.

What happens is, yes, you must format. Then, after the transfer, you will do the guide as normal. Following the guide, format your 3DS and try to reconnect your NNID to that system. If it does not do it (it says it is not linked to this console, or something similar) you will want to call Nintendo and ask them to relink it.

IMPORTANT
Do not mention WHY you did the system transfer, just say that you system transferred and this happened.
