    I'm uninstalling CFW, and the page warns that you will brick your console if you have modified critical system software. What counts as modified critical system software?

    Basically anything that must be loaded: Home, most kernel drivers, the system font, (de facto) the keyboard, ...

    As examples of non-critical stuff (= won't break your system if it fails to load because it's unsigned): Game Notes, 3DS Camera, Face Raiders, ...

    @Adam_Elhalawany, you should keep CFW if it can be helped. Uninstalling CFW carries a high risk of softbricking your system. If you have a preflashed NTRboot flashcart on the ready, this will help in unbricking if uninstalling CFW goes awry. Here's the tale of my n3DSXL CFW removal attempts & brickings in this thread.

    If you're selling the system, I would just Format System Memory, update to boot9strap v1.3, and place Luma3DS v9.1 on CTRNAND with no options selected in Luma3DS configuration.

    If this is a gift for someone, like a younger child, who is better off having an OFW-like setup, follow the additional step of substituting the boot.firm on the SD card with Rei-Six like in this post.
