This guide will provide instructions on how to restore a backup of your NAND with BootMii. Please bear in mind that this is usually the <strong>last resort</strong> method of repairing a brick if you have one, and if it does not fix your issue, you may have to seek support. If you are still able to enter BootMii, make an attempt to enter the Homebrew Channel instead so that you may attempt to [identify and repair the brick](bricks) using other methods.
If the screen stays black and the blue disc drive light is blinking upon launching BootMii, you are missing the BootMii files on your SD card. Download [this zip file](https://static.hackmii.com/bootmii_sd_files.zip) and extract it to the root of your SD card, then try again.
Family edition Wiis (Wiis without GameCube ports) CANNOT restore NAND backups. This is because of the lack of GameCube ports which are required on non-boot2 Wiis to enter the restoration confirmation code. For additional help, please seek support.
For example, if you want to restore your Wii Message Board data, use Dolphin to import your NAND backup. In Dolphin, go to `File -> Open User Folder`, and find `Wii/title/00000001/00000002/data/cdb.vff`, copy it to your SD card, and use [WiiXplorer](https://oscwii.org/library/app/wiixplorer) to restore it in the corresponding location.
If you want to restore a game's save data, use Dolphin to import your NAND backup, use `Tools > Export All Wii Saves` to export all your saves to your SD card, and use Data Management to move it to your Wii.
+ If you have not done anything to cause a brick (or you're starting up your Wii after a long time), then it is probably a [Wi-Fi Brick](bricks#wi-fi-brick).
+ You must use the POWER (right) and RESET (select) buttons on your console, or a GameCube controller plugged into port 1 to navigate BootMii. To navigate with a GameCube controller, click left/right on the +Control Pad on a GameCube controller. To select, press A.
If you were restoring a NAND backup in order to repair a brick and this did not fix your issue, please consult [the bricks portion](bricks) of this guide.
