vWii Decaffeinator allows you to restore your vWii without the need of a NAND Backup
Please backup your SLCCMPT and OTP before using this tool!
This uses the fact that the Wii U will redownload many missing files when performing a System Update.
So this homebrew will remove Files that can be redownloaded and forces a System Update.
This even works while being on the latest Firmware Version!
Choose an option from the menu and confirm with START.
After a mode has finished press any button to launch System Settings where you can perform an update.
The update folder will be recreated if you deleted it! Make sure to delete it again if you want to block updates
Light mode
This will redownload every essential System Title including all IOS
Aggressive Mode
This will remove EVERYTHING!
Save Data, Installed Channels, ...
Force Update
This will force an update which may redownload any missing files
Regenerate setting.txt
This will regenerate the setting.txt which is the only file that can't be recovered by any of the other modes.
The file will be regenerated from the consoles region and serial which can be read from the Wii U mode.
Advanced options
This lets you manually configure what should be redownloaded
