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://en.wikipedia.org/wiki/Magnet_URI_scheme) links on this page, you will need a torrent client like [Deluge](http://dev.deluge-torrent.org/wiki/Download).
If you have a PIN enabled on Luma3DS, SafeB9SInstaller will give you an "OTP Crypto Fail" error unless you temporarily disable your PIN (you can re-enable the PIN after the update).

There have been reports of a wave of bans being handed out to CFW users by Nintendo. To protect yourself, please do the following steps before starting this guide:
1. Go to System Settings, then "Internet Settings", then "SpotPass", then "Sending of System Information"
1. Disable the "Sending of System Information" option
1. Exit the System Settings
1. Go to your Friend List (the [orange Face Icon]({{ "/images/friend-list-icon.png" | absolute_url }}) in the top row of your Home Menu)
+ If you receive an error and are kicked out of the menu, the Friend List setting is either already disabled or your console cannot connect to Nintendo's servers (due to a ban or connection issues)
1. Go to the Friend List settings, then "Friend Notification Settings", then "Show friends what you're playing"
1. Disable the "Show friends what you're playing" option

### 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`.
