* It probably isn't why some part of your console is broken.
* It isn't going to permanently break your console. The worst that would happen is Luma3DS needs updating (that's the {{code|boot.firm}} file on your SD card).

* If you are selling the console, it might be a good idea to remove it then, but you should check first.

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:
