How to obtain switch firmware
To legally obtain the Nintendo Switch firmware, you'll need to extract it directly from a Nintendo Switch console that you own. This is usually done with homebrew tools, which require putting your Switch into RCM (Recovery Mode) and using software to dump the firmware files. Here's a step-by-step guide:
Requirements
Nintendo Switch with Firmware 20.0.1 or Lower for Easy Access (this is easier for homebrew, though newer versions can still work).
A Compatible USB-C Cable to connect your Switch to a computer.
Homebrew Tools (Lockpick RCM) – This tool allows you to extract firmware and keys from your Switch.
Steps to Obtain Switch Firmware
Put Your Switch in Recovery Mode (RCM)
Power off your Switch completely: Hold the Volume Up button and press the Power button to enter RCM mode.
Some models require a jig (a small plastic tool) in the right Joy-Con rail to short the pins, allowing RCM to be accessed.
Install TegraRcmGUI on Your Computer:
Download and install TegraRcmGUI on your computer. This tool will help you send payloads to your Switch.
Connect your Switch to your computer via a USB-C cable.
Download and Run the Lockpick_RCM Payload:
Download the Lockpick_RCM payload from a trusted homebrew source.
Open TegraRcmGUI, and load the Lockpick_RCM payload file.
Press the "Inject Payload" button in TegraRcmGUI to send Lockpick_RCM to your Switch.
Your Switch should now display the Lockpick_RCM interface if the payload was injected correctly.
Dump Firmware and Keys:
Follow the prompts in Lockpick_RCM to dump the firmware files and console keys. The firmware files will be saved to the microSD card on your Switch.
Transfer the Files to Your Computer:
Power off the Switch, remove the microSD card, and insert it into your computer. Copy the dumped firmware files (they may be inside a folder named switch/firmware) to a location on your computer.
Frequently Asked Questions
Do I need to update firmware for every game?
Not all games. However, new releases (like Zelda: Echoes of Wisdom) often require the latest firmware (V21.1.0) to boot or fix graphical glitches.
Does this work on Yuzu Android?
Yes! For Yuzu Android, go to Settings > Install Firmware and select the firmware zip file directly.
My game is still not working after update?
Make sure you also update your Prod Keys to match the firmware version (V21.1.0). Mismatched keys and firmware are the #1 cause of errors.
