How to Format a Nintendo 3DS Family System's Memory
In this article, you'll learn how to format system memory.
Important
If you have linked a Nintendo Network ID to your system, your Nintendo eShop account activity will be unavailable until you link your Nintendo Network ID again.
It is not possible to set the system to a previous system menu version. Once the system has been updated, it cannot be rolled back.
Note
Formatting does not allow you to link the Nintendo Network ID to another system.
Use the System Transfer option to move the Nintendo Network ID to another system.
If the system does not have an Nintendo Network ID linked and is being sold or given to someone else, remove the Nintendo eShop account before formatting the System Memory.
