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

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. Entre no Homebrew Launcher segurando (A) enquanto inicia seu jogo Haxchi de DS do Virtual Console
  2. Inicie o nanddumper
  3. Use os botões direcionais para definir as seguintes opções:
    • Dump SLC (528MB): yes
    • Dump SLCCMPT (528MB): yes
    • Dump MLC (8GB/32GB): optional
    • Dump OTP (1KB): yes
    • Dump SEEPROM (1KB): yes
  4. Aperte (A) para copiar sua NAND
    • Be prepared to wait; this can take a while (up to several hours depending on the options you enabled)
  5. Quando completado, seu Wii U irá reiniciar automaticamente
  6. Desligue seu dispositivo
  7. Insira o seu cartão SD no seu computador
  8. 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
  9. Reinsira seu cartão SD no seu dispositivo
  10. Ligue seu dispositivo
