There are two main reset options for the Nintendo DSi, and each has a different purpose. A standard console reset may be necessary if a game or other application freezes or crashes your console. This will forcibly exit the application you are running and return you to the DSi menu screen. A factory reset will delete all the information from the system permanently and should be used if you intend to sell the console or give it to another person.
Locate the "Power" button on the lower portion of the console. It's to the lower-left side of the touch screen.
Press and release the "Power" button quickly to reset the system.
Wait for the Nintendo DSi menu to load.
Tap the "Wrench" icon on the Nintendo DSi menu to open the "Settings" menu.
Press the right arrow three times to scroll to page four and select "Format System Memory."
Select the "Format" option each time you are prompted for an answer to reset your console to its original settings. A factory reset will erase all of your saved game data, any software you downloaded from the Nintendo DSi Shop and any changes you made to the system's default settings.
Tips & Warnings
- The DSi will turn off if you hold down the "Power" button for a few seconds. Press it again to turn it back on.
