Any unsigned (illegitimate) games will be rendered unusable and will be removed during this process. Use a [save manager](https://github.com/FlagBrew/Checkpoint/releases/latest) to back up any saves that you care about.
<u><strong>STOP!!!</strong></u> Uninstalling custom firmware is an unnecessary risk that will at best waste your time and at worst <u><strong>BRICK</strong></u> your console. A better idea would be to ask for help at [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp).
* [Changed the region](region-changing) of the console
* Installed a custom keyboard
* Installed a custom HOME Menu (*not* a custom theme)
* Manually changed the encryption key (`movable.sed`) of the console
* Unbanned the console
then uninstalling CFW <u><strong>WILL BRICK YOUR CONSOLE</strong></u>. If this applies to you, [restore a clean NAND backup](godmode9-usage#restoring-a-nand-backup) before continuing.
These instructions will only work on consoles with a Luma3DS version of 8.0 or higher. 如果您所安裝的 Luma 版本較舊,您必須先更新您的 Luma3DS 再繼續。 您可遵循[這個教學](checking-for-cfw)進行更新。
+ Failure to remove all CFW software from both the 3DS and DSiWare sections before uninstalling CFW may prevent or disable access to the Data Management menu after uninstalling CFW, which will make it difficult to re-install CFW in the future
