3DS:Seedminer/Mii mining

Overview

THIS DOESN'T WORK IF SEEDMINER FAILS! DON'T WASTE YOUR TIME!

Mii Mining is an alternative to using Seedminer to obtain the devices encrpytion key(movable.sed). Use cases:

• 3DS can't connect to the internet
• 3DS is banned(this will not unban it)
• 3DS screen is damaged
• 3DS is dead

In order to obtain the encryption key of your device, you will have to brute-force it. This is an advanced process. If you need help with this or aren't experienced with computers, consider asking in the Nintendo Homebrew Discord instead.

You will need a graphics card. The more powerful it is, the faster it will be.

Windows

What you need

• The latest release of Seedminer(do NOT download the Source code to avoid confusion)
• Python 3 installed on your computer

    • You can ignore the private folder if you have it
11. 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
12. Navigate to the DCIM folder on your SD card
13. Look for the QR-Code, it will be in the .JPG format
    • You may have a lot of files in here, if you used the Nintendo 3DS Camera app a lot
14. Copy this file to a safe place on your Computer, like the desktop

1. Open the editMii Website on your computer
2. Click on "Import from...", then select "QR Code" and upload the Mii QR you copied to a safe place earlier
3. Click on "Export to...", then select "encrypted (.bin)", this will download a file named input.bin
4. Extract the latest release of Seedminer
5. Enter the windows folder
6. Copy the input.bin you downloaded earlier to the windows folder
7. In the File Explorer, replace the contents of the address bar with cmd and hit Enter
   • This should launch a command line window
8. Enter the commands and hit enter for each one:
   1. py -3 -m pip install pycryptodomex
   2. py -3 seedminer_launcher3.py id0 <id0>
      • Replace <id0> with the ID0 you pasted into a document
9. Now enter the command: py -3 seedminer_launcher3.py mii <model> <year>
   • Replace <model> with the model of your device(new or old)
   • Replace <year> with the year the 3DS was made, you often find this on the backplate, you can leave this empty if you don't know the correct answer
   • this will take a while
10. When it finishes, you will have a file called movable.sed in the windows folder
