## NAND Backup

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

?> If you have recently made a NAND backup that includes SLCCMPT and OTP, feel free to skip this step.

1. Launch the [Wii U NAND Dumper](browser-exploit).
2. Use the Wii U GamePad's D-Pad to enter the following configuration:
   - Dump SLC: **optional**
   - Dump SLCCMPT: **yes**
   - Dump MLC: **optional**
   - Dump OTP: **yes**
   - Dump SEEPROM: **optional**
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 `slccmpt.bin` and `otp.bin` files (and if you chose to go with a full backup, `seeprom.bin`, `slc.bin`, and `every mlc.bin.part` file) to your computer.
6. Delete the files from your SD Card to free up space.
7. Take the SD Card out of your computer and plug it into your Wii U console.
