Hacking Change my friend code

[raynelogens]

Hello. So I followed the directions on this guide (https://3ds.guide) to get CFW on my 11.5 o3DS. Now I have two DSes with the same friend code. Is there a way I can change one or even get my old FC back?

System format one of them. It will get a new FC.

I don't want to loose the CFW I just installed though.

The CFW itself is safe on the system even with formats.

I can confirm this. You will lose games and saves, but not CFW. If you have saves you wanna keep, back them up with JKSM before formatting.

EDIT: If you want the old friendcode back, you need a backup of the original NAND with that FC.
