CFW has become exceptionally safe to use on the 3DS over the years, both during and after setup. It is nearly impossible to brick on accident. GodMode9, the most common tool for interacting with the 3DS NAND, requires unlocking writing 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. (add something about corruption checks)

If Nintendo ever releases a new system update, there is a chance that Luma3DS will be incompatible with it. This is generally not regarded as a brick as it only breaks Luma3DS trying to boot into the firmware, it does not break running other tools such as GodMode9. Usually this is fixed in about a day and is fixed by replacing {{code|boot.firm}} on the SD card.

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

Nintendo most likely doesn't focus on 3DS security anymore. Thousands of people use custom firmware on their consoles without issue. The time where a ban is most likely is when cheats are used in public online rooms.
In the past, there was one well-documented ban wave: when Pokémon Sun and Moon leaked online, some people downloaded it and used its online services before release. Bans were given to those who had done so.

This is often considered the only real case to remove custom firmware. A buyer may not be willing to accept any kind of homebrew, or the platform may remove listings for modified consoles. Notably, eBay does this if a mention of homebrew is on the listing.
Sometimes a workaround to prevent removal may be to not mention it, but include telltale signs of custom firmware in pictures (e.g. the "Sys" string in System Settings). You may not be willing to risk it however, so removing may be the best option. In this case, you should be careful to not leave remnants that can cause problems on stock, including modified system titles. In particular, make sure the following components work:
* Console boots with stock firmware
* Nintendo 3DS Camera app
* Health & Safety Information app
* DS Download Play
* DS Internet Settings
* DS Profile Settings (launching and attempting to enter in a name)
