@DavidJamesOlsen, if your model is a n3DS, n3DSXL, or n2DSXL, you're locked-in to whichever region Nintendo eShop it's on. This can't be undone even if you region change the firmware, unlink the NNID, and System Reformat to delete everything. *

***

You can only region change the Nintendo eShop for the o3DS, o3DSXL, and o2DS.

 

If I just want to unlink a nintendo account, will this work for me? I don't need to change region or anything. Is it possible to delete all account info without doing a system format? Maybe system format is what I want though. All my installed games are on the SD.

 

Just remove or unlink?

 

I don't think it is that simple. You can do a system transfer, but I don't know of a way to straigt up remove a nintendo account without reformatting.

 

Using godmode9, i remove previous nnid on my o3dsxl and create new nnid. However, the friend list of previous nNid still there. Is thefriend list will sync to my nnid?

 

The friend list of your previous NNID stays there because your created mii is still there you will not get banned if you have your original mii and friends list.

Actually your friend list does not change at all you would have to remove friends one by one.

 

@TimeMaster Is there any way to reverse this process after doing so? I did this but now I need my NNID back on my DS. Do I just change the 1 back to a 0? Sorry I know this is an old post but I just wanted to know.

 

Just go into NNID settings and sign in again

 

@Quantumcat When I tried that, I got a message that said my information is not correct. I have triple checked my information and I know for a fact that it is all correct. Did it work for you?

 

Yeah just change the 1 back to a 0, the point of changing it to a 1 so it isn’t recognized by the system anymore, changing back will revert the changes

 

Thank you! The eShop revoked all of my titles and I needed my NNID to get them back. It worked perfectly.

 

Is there anyway of reversing the process if one was not able to sign in to their NNID for whatever reason?

 

Have a look at TimeMaster's post, two above yours.

 

I've done that, and my badges have come back, but all eShop content is still disabled (but is still installed as far I can tell).

 

Try visiting the eShop

 

Doesn't seem to trigger anything. It just asks me to log in, which I'm not able to do.

 

Oh ok, maybe what happened is you were signed out at the time you deleted your NNID? I would try ringing Nintendo, maybe they can fire off a password change process or change your associated email if it isn't one you use anymore.

 

I sorted it in the end. Turns out the tickets got uninstalled. Reinstalling them fixed it.

Thanks for your help though.

 

I would like to remove eshop account or any data associated with it. Do you know any process to do that?
