### Leitura Obrigatória
Select the appropriate page for your version from the chart below. Note that the "from" and "to" fields are inclusive. This means that, for example, the "from 9.0.0 to 9.2.0" row includes 9.0.0, 9.1.0, and 9.2.0.
Additionally, note that the last two columns of the chart refer to the last number of your version (which corresponds to the browser version installed to the system). If the version is -0 then you do not have a browser, while any number above -0 indicates a browser is installed.
In the case of "5.0.0-0U" for example, you would follow the "No Browser" column and 5.0.0 to 5.1.0 row because the system is on the a system version in that range and has no browser installed.
Your device version can be found at the bottom right of the top screen of the System Settings.

**If you are unable to follow the instructions corresponding to your specific version due to missing prerequisites, then you should see 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.
Se já tiveres hackeado a tua 3DS e tiveres um sistema CFW baseado em EmuNAND, segue todas as instruções na 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).
