# Making a NAND Backup

In case anything should go wrong in the later process and your Wii U ends up bricked, restoring a previously made NAND backup can fix it.

### Instructions

?> The Wii U NAND is (depending on your model) either 8 or 32gb. As a result of this, to create a full backup of your console's NAND, your SD Card has to be larger than the size of your NAND. If you do not have a large enough SD Card, you can skip the optional `MLC` section which includes save files and game data.

> 1. Navigate through the Homebrew Launcher and launch the `Wii U NAND Dumper` app.
> 2. Use the Wii U Gamepad's DPAD to enter the following configuration:
 - Dump SLPC: **yes**
 - Dump SLCCMPT: **yes**
 - Dump MLC: **optional**
 - Dump OTP: **yes**
 - Dump SEEPROM: **yes**
> 3. Press the A button to start the dumping process.
> 4. When the process completed, power off your Wii U, take your SD Card out of the Wii U and plug it into your PC.
> 5. To make sure you don't lose the files, copy the `slc.bin`, `slccmpt.bin`, `seeprom.bin`, and, if you chose to go with a full backup, `every mlc.bin.part` file to your computer.
> 6. Delete the files from your SD Card to free up space.
