This typically involves connecting a jig to the right Joy-Con rail while pressing the power and volume up buttons simultaneously. The Switch screen should remain black if you've entered RCM correctly. Entering RCM allows you to inject the payload and boot into CFW.

6. Inject the Payload: Use a USB cable to connect your Nintendo Switch to your computer. Use a payload injector tool (like TegraRcmGUI) to inject the payload file. Select the fusee.bin file (or the appropriate payload for your CFW) and inject it. Your Switch should now boot into the CFW environment. Injecting the payload tells the Switch to boot using the custom firmware.

7. Update System Firmware (Optional but Recommended): Once you're in CFW, you might want to update your system firmware to the latest version. Use a tool like ChoiDujourNX to update the system firmware while avoiding burning fuses. This allows you to stay compatible with the latest games without permanently altering your Switch's hardware. Updating the system firmware ensures you can play the newest games without issues.

8. Verify the Update: After the update is complete, reboot your Nintendo Switch. Check the system settings to confirm that the CFW and system firmware versions are updated correctly. Launch a game or homebrew application to ensure everything is working as expected. Verifying the update confirms that the process was successful and that your Switch is running smoothly.
