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