|

This will completely remove CFW from your device, including boot9strap and Luma3DS, for the purpose of restoring the device to stock.
|
||||
|
||||
This is almost never the solution to fix any issues you encounter with your CFW installation. A better idea would be to read the [troubleshooting](troubleshooting) page or ask (in English) for help at [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp).
