My friend gave me a 3DS XL that I want to change the pin on to access the internet and format the system memory. My friend doesn't know the pin or the answer to the forgot PIN question and I really don't want to call nintendo for this. Can anyone help me?
The standard way of dealing with a forgotten 3DS parental control code is to following the official guide for resetting the pin which does involve contacting Nintendo. Alternatively you can find various tools online that should be able to accomplish the same task without needed to contact Nintendo. One such tool available at this time is called 3DS Parental Tool.
The 3DS Parental Tool does not work with the 3DS XL, the code you have to input is too long.
I found a link to a tool that worked, and it's online with nothing to download.
