To install boot9strap on your 11.8.0 device, we exploit an oversight in the security restrictions applied to "DSiWare" applications.
To accomplish this, we use a tool called Seedminer to calculate the DSiWare encryption key (`movable.sed`) for your device.
We then use this DSiWare encryption key to decrypt a compatible DSiWare application and inject an exploit into it to run our own code.
If this key were completely random, the encryption key would be impossible to break on current computing hardware. Fortunately, the first half of the key (`movable_part1.sed`) is actually mathematically related to your device's Friend Code, allowing us to break the encryption. For information on how Seedminer works, please see [this presentation](https://zoogie.github.io/web/34⅕c3).
Note that this tool requires a PC with a powerful graphics card to break your device's DSiWare encryption. If you do not have access to one of these, there exists several online helper services where a volunteer running automated software will do this for you.
To use the [magnet](https://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).
To extract the `.7z` and `.rar` 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/).
This process will overwrite your DSiWare game's save file!

### Instructions
#### Section I - Préparatifs
1. Éteignez votre 3DS
1. Insérez votre carte SD dans votre ordinateur
1. Créez un dossier nommé `3ds` à la racine de votre carte SD si celui ci n'existe pas
1. Copiez `boot.firm` de Luma3DS `.7z` dans la racine de votre carte SD
1. Copy `boot.nds` (B9STool) to the root of your SD card
1. Copiez `boot.3dsx` à la racine de votre carte SD
1. Copy the `steelhax` folder from the Steelhax `.rar` to the root of your SD card
1. Copy the otherapp payload to the `steelhax` folder on your SD card and rename it to `payload.bin`
1. Copy `Frogtool.3dsx` from the Frogtool `.zip` to the `/3ds/` folder on your SD card
1. Copy the `private` folder from the Frogtool `.zip` to the root of your SD card
1. Navigate to the `Nintendo 3DS` folder on your SD card
1. Copy the 32 character long name of the folder you see
+ If you see multiple folders like this, perform the following:
+ Rename the `Nintendo 3DS` folder to `BACKUP_Nintendo 3DS`
+ Reinsert your SD card into your device and power on your device
+ Wait for the device to generate the SD card data
+ Power off your device and reinsert your SD card into your computer
+ Navigate to the `Nintendo 3DS` folder on your SD card
+ Copy the 32 character long name of the folder you see
+ Delete the `Nintendo 3DS` folder
+ Rename the `BACKUP_Nintendo 3DS` folder to `Nintendo 3DS`
1. Paste your 32 character long folder name into a document you can reference later
+ This folder name is also known as your "ID0"
1. Réinsérez votre carte SD dans votre 3DS
1. Allumez à présent votre 3DS
1. Accédez à votre liste d’ami ([icône de visage orange] ({{"/images/friend-list-icon.png" | absolute_url}}) dans la rangée du haut de votre Menu HOME)
+ If you receive an error and are kicked out of the menu, you either must create a new Mii or your console cannot connect to Nintendo's servers (due to a ban or connection issues)
1. Find your Mii profile, then find the "Friend Code" field on the top screen
#### Section II - Seedminer
1. Open [Bruteforce Movable](https://bruteforcemovable.com/) on your computer
+ This site can automate the retrieval of `movable_part1.sed` (using a bot 3DS console) and the breaking of your device's DSiWare encryption (using a volunteer's computer to run Seedminer)
+ If you already have access to a 3DS capable of launching the Homebrew Launcher, you can manually retrieve your `movable_part1.sed` using that device by following [these](https://jisagi.github.io/SeedminerGuide/seedminerSelf/#section1) instructions
+ If you already have access to a PC with a powerful graphics card, you can manually calculate your `movable.sed` using it by following [these](https://jisagi.github.io/SeedminerGuide/seedminerSelf/#section2) instructions
+ If the automated service is nonfunctional and you cannot do one or both of those manually, join [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp) and ask (in English) for someone there to assist you
1. Enter your device's Friend Code (with no spaces or dashes) into the "Your friend code" field
1. Paste your device's 32 character long folder name into the "Your ID0" field
1. Complete the "I'm not a robot" captcha
1. Select "Go"
1. When prompted, use the "Register Friend" button on your device to add the friend code of the bot 3DS console
1. Wait for the site to update
+ If it does not, refresh the page
1. Select "Continue"
1. Wait for the process to complete
+ This can take a while (up to an hour in some cases)
+ If you are still waiting after an hour, join [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp) and ask (in English) for someone there to assist you
1. When the process has completed, download your `movable.sed` file from the site
#### Section III - Steelminer
1. Launch "Steel Diver: Sub Wars" once and select a Mii to initialize your save file
+ Decline the game update when prompted
+ If you have already updated the game, use the Data Management menu of the System Settings to delete the update
1. Exit "Steel Diver: Sub Wars"
1. Éteignez votre 3DS
1. Insérez votre carte SD dans votre ordinateur
1. Open [the Steelminer website](http://steelminer.jisagi.net/#Section_III) on your computer
1. Select your `movable.sed` file
1. Select "Start!"
1. Wait for the process to complete
1. Navigate to `Nintendo 3DS` -> `<ID0>` -> `<32-character-id>` -> `title` -> `00040000` -> `<8-character-region>` -> `data` on your SD card
1. If the exploit was successful, your device will have loaded b9sTool
1. Sélectionnez "Install boot9strap" et validez
1. Quittez b9sTool, puis éteignez votre appareil
+ Vous allez peut-être devoir forcer la fermeture en maintenant le bouton d’alimentation enfoncé
#### Section VI - Configuring Luma3DS
1. Démarrez la console en maintenant (Select) enfoncé pour accéder au menu de configuration de Luma3DS
+ If you encounter issues launching the Luma configuration menu, [follow this troubleshooting guide](https://github.com/zoogie/b9sTool/blob/master/TROUBLESHOOTING.md)
