Hello, as the title said, I have bought a used n3DSxl with an existing NNID and went on with the guide on 3ds.guide (praise the sun and the author) to fully and succesfully install the luma/arm9 cfw on my sysnand. Now I have discovered I can inject a new nnidsave.bin to "overwrite" the existing NNID erasing so all the traces of the previous owner. My question is: I have read that such procedure (injecting the nnidsave) is safe when done on an EMUnand... since I don't have an EMUnand anymore and I directly launch a CFW sysnand thanks to the arm9/luma thingy, is it safe for me to inject the blank nnidsave or will I brick my console? Sorry if I explained badly, I am relatively new to this stuff. Be merciful and thanks in advance!
