### Required Reading
|
|
|
|
This section will create a backup of your device's internal NAND memory on your SD card, which will allow you to restore your device via a hardmod in the case of a brick.
|
|
|
|
### Instructions
|
|
|
|
{% capture notice-1 %}
|
|
A backup of the MLC partition is optional as it's huge in size, and most bricks that need MLC to be restored are done by user-error.
|
|
|
|
If you want a full backup including MLC, and have a black Wii U (32GB) model, your SD card must be at least 64GB in size. If you have a white (8GB) Wii U model, your SD card must be at least 16GB in size.

1. While in the Homebrew Launcher, launch nanddumper
|
|
+ If you left the Homebrew Launcher, return to it by running the Wii U browser and go to `wiiuexploit.xyz`
|
|
1. Use the D-Pad to set the following options:
|
|
+ Dump SLC (528MB): **yes**
|
|
+ Dump SLCCMPT (528MB): **yes**
|
|
+ Dump MLC (8GB/32GB): **optional**
|
|
+ Dump OTP (1KB): **yes**
|
|
+ Dump SEEPROM (1KB): **yes**
|
|
1. Press (A) to dump your NAND
|
|
+ Be prepared to wait; this can take a while (up to several hours depending on the options you enabled)
|
|
1. When it has completed, your Wii U will reboot automatically
|
|
1. Power off your device
|
|
1. Insert your SD card into your computer
|
|
1. Copy `slc.bin`, `slccmpt.bin`, `otp.bin`, and `seeprom.bin`, and each `mlc.bin.part` file (if you chose to backup the MLC partition) from the root of your SD card to a safe location on your computer
|
|
+ Make backups in multiple locations (such as online file storage)
|
|
+ These backups will save you from a brick and/or help you recover files from the NAND image if anything goes wrong in the future
|
|
1. Reinsert your SD card into your device
|
|
1. Power on your device
