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.
  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.
