### Required Reading

This page is for existing arm9loaderhax users to update their devices to boot9strap.

All future releases of Luma3DS will only be made in the `.firm` format, which will only be compatible with boot9strap and sighax. This means that to continue receiving the latest updates of Luma3DS, you should use this page to update your installation.

To use the [magnet](https://wikipedia.org/wiki/Magnet_URI_scheme) links on this page, you will need a torrent client like [qBittorrent](https://www.qbittorrent.org/download.php) or [Deluge](http://dev.deluge-torrent.org/wiki/Download).

To extract the `.7z` files linked on this page, you will need a file archiver like [7-Zip](http://www.7-zip.org/) or [The Unarchiver](https://theunarchiver.com/).

While we believe that custom firmware is safe for online use, there have been online network bans in the past, primarily for cheating and suspicious eShop behavior.

### What You Need

Note that the following required file named `secret_sector.bin` is the same one that was found in the various `data_input.zip` file versions. If you already have that file on your disk somewhere, you can use that one instead of downloading the one below.
{: .notice--info}

Note that, only on New 3DS, `secret_sector.bin` is needed to revert the arm9loaderhax exploit, which is why it is not needed for the installation of boot9strap on a stock console. If you do not have a New 3DS, you do not need `secret_sector.bin`.
