Installing REI3 on NixOS Latest

In this tutorial, we will guide you through the steps to install REI3 from https://rei3.de/home_en/ on the latest version of NixOS. REI3 is a modified version of the Nintendo Switch custom firmware ReiNX.

Before starting, make sure you have access to the root user account or a user account with sudo privileges on your NixOS system.

Step 1: Install Git

Git is a distributed version control system. We need Git to clone the REI3 repository from Github.

Run the following command to install Git:

sudo nix-env -iA nixos.git

Step 2: Clone the REI3 Repository

Use Git to clone the REI3 repository from Github to your local machine. In the terminal, run the following command:

git clone https://github.com/Reisyukaku/REI-NX.git

Step 3: Install Dependencies

REI3 requires certain dependencies to function properly. Run the following command to install the required dependencies:

sudo nix-env -iA nixos.pkgconfig
sudo nix-env -iA nixos.gcc
sudo nix-env -iA nixos.coreutils
sudo nix-env -iA nixos.findutils
sudo nix-env -iA nixos.makeWrapper
sudo nix-env -iA nixos.sdcc
sudo nix-env -iA nixos.pkg-config
sudo nix-env -iA nixos.libelf
sudo ln -sf $(which libelf.so.1) /usr/lib/libelf.so

Step 4: Build and Install REI3

Navigate to the REI3 directory that you cloned in Step 2. In the terminal, run the following command to build and install REI3:

make
make install

Step 5: Verify REI3 Installation

Once the installation is complete, restart your Nintendo Switch console into recovery mode by holding the Volume + and Power Buttons.

Connect your console to your computer using a USB cable. On your NixOS machine, navigate to the REI3 directory that you cloned in Step 2.

In the terminal, run the following command:

sudo python3 tegrarcm.py

Then run the following command to inject the REI3 payload:

sudo ./rcmadm rcm2

Your Nintendo Switch should now boot into REI3.
