**If you are unable to follow the instructions corresponding to your specific version due to missing prerequisites, then you should either update to the latest version or use the "All Versions" row for methods that work regardless of system version.**
For all versions you can also [Cartridge Update](cart-update) (or use a standard system update) to get to a higher version in the same column to follow its instructions.
Hvis du allerede har hacket din 3DS før og har et EmuNAND basert CFW oppsett, bare følg alle instruksene meden du er på SysNAND. Replace any files that already exist. Your data will be transferred from EmuNAND to your new B9S install at the end. If you use menuhax, you should [clear Home Menu's extdata](troubleshooting#clear-home-menu-extdata) to remove it before beginning.
This page is for instructions on how to install boot9strap to a *stock* 3DS or 2DS. If you already have arm9loaderhax installed and are looking to update to boot9strap, follow [A9LH to B9S](a9lh-to-b9s).

{% capture notice-1 %}
While we believe custom firmware is relatively safe at this time, it is important to note that it will never be "ban free".
You should avoid the following actions:
1. Piracy
1. Cheating online
1. Suspicious behaviour on eShop (for example, credit card chargebacks)
We believe SpotPass and StreetPass are also safe for use at this time.
