If you have recently bought a Wii U and find yourself with an account or two that is password locked, this is how you can delete them without acquiring the passcode.
Instructions
- Download the latest release of FTPiiU.
- Extract the
ftpiiu.wpsfrom the zip tosd:/wiiu/environments/aroma/pluginsfolder on your SD Card. - Download an FTP client of your choice(Filezilla, WinSCP, etc).
- Insert the SD card back into your Wii U and boot up Aroma.
- Open the plugin menu, navigate to the FTPiiU tab and your IP should show.
- Take note of this, you will need it later.
- Set system files access to true.
- Boot up your preferred FTP client.
- Your console and PC must be on the same network.
- Input your IP address, leaving the port blank, then hit connect.
- You should see a list of directories.
- Navigate to
storage_mlc/usr/save/system/actand There should be either one or multiple 800000X folders. These are the accounts. - Open one and you will find an account.dat file. Drag this file to your desktop and open it in notepad as this will tell you whose account it belongs to.
- Once you've figured it out, delete the entire folder or folders.
- Disconnect the client and then shut down the console(do not force power off).
- Boot up the Wii U again, and if done successfully, the account(s) should be gone.
