CFW has become exceptionally safe to use on the 3DS over the years, both during and after setup: It is nearly impossible to brick your console on accident. [[3DS:GodMode9|GodMode9]], the most common tool for interacting with the 3DS NAND, requires unlocking the write protection with a button combination when you are about to do something that could cause damage. The button combination requires deliberate inputs and is impossible to do by accident.

Moreover, GodMode9 contains integrated repair features and allows you to run useful tools for troubleshooting and repairing your console software: If your console is already "bricked", removing CFW will prevent you using them to find and resolve the console's possible problems.

If Nintendo ever releases a new system update, there is a chance that Luma3DS will be incompatible with it: It is not a brick as it prevents the complete boot of Luma3DS, but does not break other tools such as GodMode9. Usually a new release is made in about a day and can be fixed by replacing <tvar name="boot.firm">{{code|boot.firm}}</tvar> on the SD card.
Nintendo no longer releases updates for the 3DS. The last update was released in May 2023, shortly after the shutdown of the eShop.

The last update to break Luma3DS was 11.14.0-46, released on 17th of November, 2020. The last one before that was 11.8.0-41, released on 30th July, 2018.

CFW provides access to tools to make your own backups of your games, their saves, and the system's internal storage (the NAND). These allow for better backups than what Nintendo normally allows. For example, if your console is ever lost or broken, everything can be manually migrated to a replacement console. SD card data can be migrated if you have the <tvar name="movable.sed">{{Code|movable.sed}}</tvar> from the original console, which is inside the <tvar name="essential.exefs">{{Code|essential.exefs}}</tvar> made during setup. NAND data (e.g. Friend List, Mii Maker, StreetPass Mii Plaza) can be transferred from a NAND backup.

Nintendo does not focus on 3DS security anymore, as thousands of people use custom firmware on their consoles without issue. Bans are the most likely when cheats are used in public online rooms.

Moreover, Nintendo has shut down online play and services for the 3DS on the 8th of April, 2024: There is be nothing to be banned from anymore.

As of June 2026, ''Nintendo of America'' only repairs the New 2DS XL, while ''Nintendo of Japan'' and ''Nintendo of Europe'' no longer repair any models.

Nintendo might not like receiving a console with [[3DS:boot9strap|boot9strap]] on it, so removing custom firmware temporarily would be a good idea. In this case you should make backups of the NAND, as Nintendo does not repair consoles, they replace them instead.
