3DS:Seedminer/Manual mining

This article is not for instructions on how to use BruteforceMovable or Mii Mining.
For help with BruteforceMovable, see our custom firmware installation's page.
For help with Mii Mining, see the Mii Mining page.

Manual mining is a name for one of two processes that allows you to find a console's movable.sed without the help of an outside resource. The method described in this guide is also named Manual Mining - the other is called Mii Mining and should only be used when manual mining is also impossible.

Requirements

• A computer with a dedicated GPU that is running Windows, macOS, or Linux.
  • Integrated graphics will still work, but are extremely underpowered and may cause mining to take multiple hours. This guide does not recommend their use.
• The target console's ID0.
• A second, already-hacked 3DS (called the source console from now on).
  • Both the source console and target console must be able to add friends.

Instructions

What you need

• The [latest] and [v2.1] releases of seedminer (the .zip files NOT labeled as source code).
• Any 3.x version of [python].

Section I - Prep Work

In this section, you will obtain needed information and prepare your PC & the source console to run the programs needed for mining.

1. Extract the contents of the Seedminer .zip to a folder anywhere on your PC - this will be where multiple other files are placed
2. Inside the extracted Seedminer folder, click on the address bar and type cmd, then press Enter - a Command Prompt window will appear
3. In Command Prompt, type py -3 -mpip install pycryptodomex - once it's done installing, keep the window open as you will need it later
4. Put the target console's SD card into your computer, navigate to the Nintendo 3DS folder on the SD, and copy the name of the 32-character-long folder directly inside
   • This folder, known as the ID0, is system-specific. Only one should be present - if you see multiple, follow these instructions.
5. Put the target console's SD card back into the target console and put the source console's SD card into your computer
6. Copy seedstarter.3dsx from the RELEASE_v2.1 zip to sdmc:/3ds on the source console's SD card
7. Put the source console's SD card back into the source console

Section II - Obtaining LFCS

In this section, you will obtain the movable_part1.sed needed for manual mining.

1. Turn on both consoles
2. On both consoles, go into the Friends List, click the add friend button, and add the other console as a friend
3. Once the consoles are friended, on the source 3DS, back out of the Friends List and open the Homebrew Launcher
4. Open seedStarter and press B to dump all LFCS from friend codes
5. Press A and then START to exit seedStarter, close the Homebrew Launcher, then turn off the source 3DS and insert its SD card into your computer
6. On the SD card, navigate to sdmc:/seedstarter/LFCS and copy the file with the target console's friend code in its name
7. Go to the Seedminer folder and paste this file there, then rename it to movable_part1.sed

Section III - Mining

In this section, you will mine movable.sed in order to continue with the normal guide.

1. Inside the Command Prompt window, enter the command py -3 seedminer_launcher3.py id0 <id0>
   • Replace <id0> with the ID0 of the target console
2. Once completed, enter the command py -3 seedminer_launcher3.py gpu
   • This will take up to 10 minutes, depending on your GPU's strength
3. Once it is finished, the file movable.sed will appear in the Seedminer folder - use this in place of one obtained from BruteforceMovable
