Injecting Fusee on ARM Linux and/or using USB-C port

[lightwo]

If you find yourself in a situation like this:

• You have an ARM Linux device and/or only have USB-C ports
• None of the injectors appear to work
  • You get this message with ns-usbloader (using ARM Linux; indeed, no ARM Linux binaries are provided):
    

    Unfortunately your platform (...) is not supported
    But you could file a bug with request.
    
    Nothing has been sent to NS. Execution stopped.

  • You get this message with fusee-interfacee-tk (using USB-C port over a USB-C/USB-C cable; can't find device over XHCI):
    

    This device needs to be on a supported backend. Usually that means plugged into a blue/USB 3.0 port!
    Bailing out.

There's actually a way!

This assumes you're either running as root or using the following udev rules in /etc/udev/rules.d/60-nx-switch.rules:

# Nintendo Switch
SUBSYSTEM=="usb", ATTRS{idVendor}=="057e", ATTRS{idProduct}=="3000", MODE="0666"
# Nintendo Switch recovery mode (RCM)
SUBSYSTEM=="usb", ATTRS{idVendor}=="0955", ATTRS{idProduct}=="7321", MODE="0666"

Method 1​

1. Install Python
2. Get fusee-interfacee-tk
3. Download Hekate payload
4. Pass --override-checks argument:
   python3 fusee-launcher.py --override-checks hekate_ctcaer_x.x.x.bin

This enables using a Linux laptop/tablet/phone to inject a payload. That particular argument bypasses the XHCI check that ends up being unnecessary, since it works anyway.

Method 2​

Alternatively, if you aren't lazy and have the means of compiling C code, rather than installing Python, build fusee-nano and it should work just as well.

Final Notes​

It is also worth checking if your files are intact. Using curl -O on GitHub download URLs results in 0B files, which may result in your payload being broken.
