!> This has the potential to destroy your vWii NAND if you are not careful! Please consider [backing up](mocha/online-exploit/nand-backup) your SLCCMPT and OTP if you do not yet have them backed up!

### What You Need

- A working [Homebrew installation](introduction) on Wii U side.

### Recovering Process

You will be provided with various options. It is recommended to first attempt restoring through the `Advanced options` menu if you know what to restore, or `Light mode` if you aren't sure. In extreme cases where no other option solves the issue, `Aggressive mode` should be chosen.
