Requirements

Instructions

Section I - Dumping and Patching IOS 36

  1. Download both the Simple IOS Patcher for Wii mini and RealWnD for Wii mini, and extract both zip files to the root of your USB drive.

  2. Insert the USB drive into your Wii mini, and launch the Simple IOS Patcher for Wii mini from the Homebrew Channel.
  3. It should start to automatically detect your IOS 36 version and proceed to patch it into slot 236. It will also give you the IOS 236 wad file on your USB.

Section II - Dumping the NAND

  1. Launch RealWnD for Wii mini from the Homebrew Channel.
  2. It should automatically detect IOS 236 on your Wii mini and apply some runtime patches to begin dumping your NAND.
  3. When it is done, you will have 3 new files on your USB:
WiiFlash_n_ECC.img
WFD_XXX_YY.img
WiiFlash.log

The WiiFlash_n_ECC.img is your NAND image. The other two files are “error” data, and are useless.

Section III - Dumping the Wii mini’s Keys

  1. Launch xyzzy mod from the Homebrew Channel.
  2. Select USB device
    • It should start retriving your console information.

    • You will have 5 new files on your USB:
     bootmii_keys.bin
 device.cert
 keys.txt
 otp.bin
 seeprom.bin

For now, only the bootmii_keys.bin file is required.

Section IV - Optional: Upload your NAND to Dolphin Emulator

  1. Connect the USB to your PC.
  2. Open Dolphin Emulator on your PC.
  3. Select the tools tab, and in the dropdown menu, go to “manage NAND”, and then select “Import BootMii NAND Backup”.
  4. Select the dropdown to the right next to the file name bar and then choose the “All Files” option.
  5. Locate your WiiFlash_n_ECC.img file and select “open”.
  6. Another window will pop up asking for the keys. Locate bootmii_keys.bin and select open.
