## 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 8GB 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.

?> Restoring a NAND Backup on the Wii U requires additional hardware and micro soldering skills. <br>However, making a NAND Backup is **always** useful, so please do not skip it. <br>Your NAND Backup is unique to your system. Backups from other consoles **won't** work.

1. Navigate to `nanddumper` using the GamePad and press A to launch it.
2. Use the Wii U GamePad's D-Pad to enter the following configuration:
   - Dump SLC: **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`, `otp.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.
