Technical Details (optional)

To install boot9strap on your console, we derive your console’s unique encryption key. To accomplish this, we use a tool called Seedminer to calculate the data encryption key (movable.sed) for your console.

For information on how Seedminer works, see this presentation.

This method uses a powerful graphics card to perform the calculations needed. A volunteer-run website is used for the purpose of assisting you with this method.

Section I - Prep Work

In this section, you will get the necessary details from your 3DS that are required to figure out your console’s encryption key.

Before following this section:

  • Ensure that you have turned on your console with the SD card inserted at least once to generate the necessary data
  • Ensure that your console is connected to the Internet (you should see a blue “Internet” indicator on the top-left corner of the HOME screen)
  1. Power off your console
  2. Insert your SD card into your computer
  3. Navigate to the Nintendo 3DS folder on your SD card
  4. Copy the name of the 32-letter folder you see directly inside Nintendo 3DS
    • This 32-letter name is system-specific and will be different for each console
    • If you see multiple 32-letter folders, follow these instructions
    • You can ignore the private folder if you have it

  5. Paste your 32-letter folder name into a document you can reference later
    • This folder is known as your “ID0”. Take note of this as this guide will refer to it as such later
  6. Power on your console
    • Your SD card does not need to be inserted at this point
  7. Go to your Friend List (the orange Face Icon in the top row of your HOME Menu)
    • 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)
  8. Find your Mii profile, then find the “Friend Code” field on the top screen

Section II - Seedminer

In this section, you will use the Bruteforce Movable website to retrieve your console’s encryption key in the form of movable.sed.

  1. Open Bruteforce Movable on your computer
  2. Enter your console’s Friend Code (with no spaces or dashes) into the “Your friend code” field
  3. Paste your console’s 32 character long folder name into the “Your ID0” field
    • Do not attempt to enter the ID0 manually, as it is easy to make a mistake. Ensure the ID0 is entered correctly by copying and pasting it from where you saved it in the previous section
  4. Select “Go”
    • If the site immediately goes to step 4, the website has already correctly processed your bruteforce request. You can download your movable.sed file and continue to the next section. You do not need to (re-)add the bot
  5. Use the “Register Friend” button on your console to add the bot’s friend code as given by the website
    • If prompted, the name that you give to the friend does not matter
  6. Wait for the site to update
    • If it does not, wait a few minutes before refreshing the page once
  7. Once the site processes your information, the site will continue to Step 2: Bruteforce automatically
  8. Wait for the remainder of the process to complete
    • This is usually fast (1-5 minutes)
    • During this process, the bot you added may not show up on your 3DS. As long as the website updates, this is not an issue
    • If you are still waiting after half an hour, join Nintendo Homebrew on Discord and ask (in English) for someone there to assist you
    • If you get “We were unable to successfully complete your bruteforce request. :`(“, follow the respective troubleshooting on this page
  9. When the process is completed, download your movable.sed file from the site
    • Keep this file as you will need it in the upcoming page
  10. Power off your console

Next step: BannerBomb3

Once you have your console’s encryption key (movable.sed), you can use it in conjunction with BannerBomb3, which uses your movable.sed file to take advantage of exploits in the System Settings application.
