Update Nintendo Switch Firmware: A Hacker's Guide

Keeping your Nintendo Switch firmware up-to-date is crucial, especially if you're into the homebrew scene. But let's be real, navigating the update process with a hacked Switch can feel like walking through a minefield. One wrong step, and you could brick your beloved console. That's why we've put together this guide – to help you update your Nintendo Switch firmware safely and efficiently, while preserving your hacking setup.

Why Update Your Firmware?

Before we dive in, let's quickly cover why you might want to update your firmware in the first place. Nintendo regularly releases updates that include:

  • New Features: Who doesn't love shiny new features? Firmware updates often bring enhancements to the user interface, new functionalities, and other cool additions.
  • Bug Fixes: Nobody likes glitches and errors. Updates address known issues to provide a smoother gaming experience.
  • Security Patches: This is a big one, especially for those using custom firmware. Updates patch vulnerabilities that could be exploited by malicious actors.
  • Game Compatibility: Newer games often require the latest firmware to run properly. Keeping your Switch updated ensures you can play the newest titles.

However, for those with modified Switches, it's not as simple as hitting the "Update" button. A standard update can remove your custom firmware, potentially brick your console, or introduce incompatibilities with your existing homebrew setup. That's why following a safe and informed approach is essential.

Preparing for the Update

Okay, guys, before we even think about updating, we need to do some prep work. This is where a little bit of caution goes a long way. Think of it as putting on your safety gear before heading into a dangerous zone.

Back Up Your NAND

Seriously, this is non-negotiable. A NAND backup is a complete copy of your Switch's internal memory. If anything goes wrong during the update process, you can restore your Switch to its previous state using this backup. It's like having a reset button for your entire console. There are various tools available to create a NAND backup, such as hekate. Make sure to store this backup in a safe place, preferably on multiple devices, like your computer and an external hard drive.

Check Compatibility

Not all custom firmware is compatible with the latest Nintendo Switch firmware. Before updating, make sure that your CFW (Custom Firmware) of choice supports the new version. Check the official websites or forums of your CFW (like Atmosphere or ReiNX) for compatibility information. If your current CFW doesn't support the new firmware, you'll need to update it first.

Gather Necessary Files

You'll likely need a few files to perform the update, including:

  • The latest version of your CFW: As mentioned above, ensure your CFW is compatible with the target firmware.
  • The latest version of hekate: This is a popular bootloader that's essential for launching CFW.
  • ChoiDujourNX: This tool is used to perform the actual firmware update while minimizing the risk of bricking your console. Make sure you download the latest version.
  • Your Switch's firmware files: You can obtain these files from various sources, but make sure they're legitimate and not tampered with.

Charge Your Battery

This might sound obvious, but ensure your Nintendo Switch has a full charge before starting the update process. A dead battery mid-update is a recipe for disaster.

Step-by-Step Update Guide

Alright, with the preparations out of the way, let's get down to the nitty-gritty. Follow these steps carefully to update your Nintendo Switch firmware.

Step 1: Update hekate

hekate is the bootloader that allows you to launch your CFW. Keeping it updated is crucial for compatibility. To update hekate:

  1. Download the latest version of hekate from its official source.
  2. Extract the contents of the downloaded archive to the root of your Switch's SD card, overwriting any existing files.

Step 2: Prepare ChoiDujourNX

ChoiDujourNX is the tool we'll use to perform the actual firmware update. Here's how to get it ready:

  1. Download the latest version of ChoiDujourNX.
  2. Extract the contents of the downloaded archive to the switch folder on your SD card. If the switch folder doesn't exist, create it.
  3. Place the firmware files you downloaded earlier into a folder on your SD card. Name this folder something descriptive, like Firmware 17.0.0.

Step 3: Launch ChoiDujourNX

  1. Insert your SD card into your Nintendo Switch.
  2. Boot your Switch into RCM (Recovery Mode). This usually involves using a jig to short the correct pins on the Joy-Con rail.
  3. Launch hekate using a payload injector.
  4. In hekate, navigate to Launch > CFW (sysNAND) or CFW (emuNAND), depending on your setup.
  5. Once your CFW is running, launch ChoiDujourNX from the Homebrew Menu.

Step 4: Perform the Update

Now comes the moment of truth. Follow these steps carefully:

  1. In ChoiDujourNX, select the folder containing your firmware files.
  2. ChoiDujourNX will analyze the firmware files and display information about the update.
  3. Important: Select the option to create an emuNAND if you don't already have one. An emuNAND is a separate partition on your SD card that contains a copy of your Switch's system software. This allows you to keep your sysNAND (the internal memory) clean and untouched. If you are already on emuNAND, make sure that you select the correct drive to update.
  4. Select the option to preserve your exFAT drivers if you're using an SD card formatted with exFAT. This will prevent issues with SD card compatibility after the update.
  5. Start the update process. This may take some time, so be patient and don't interrupt the process.

Step 5: Reboot and Verify

  1. Once the update is complete, reboot your Nintendo Switch.
  2. Boot back into your CFW through hekate.
  3. Go to System Settings and verify that your firmware has been updated to the correct version.

Troubleshooting

Sometimes, things don't go according to plan. Here are some common issues and how to resolve them.

Bricked Switch

If your Switch gets bricked (i.e., it won't turn on or displays an error message), don't panic! This is where your NAND backup comes in. You can use a tool like hekate to restore your Switch to its previous state.

SD Card Issues

If you encounter issues with your SD card after the update, try reformatting it using a tool like guiformat. Make sure to back up any important data before reformatting.

CFW Incompatibility

If your CFW is not compatible with the new firmware, you'll need to update it. Check the official websites or forums of your CFW for updates.

Staying Safe

Updating a hacked Nintendo Switch can be risky, but by following these guidelines, you can minimize the risk and keep your console safe.

  • Always back up your NAND before making any changes to your system.
  • Double-check compatibility before updating your firmware or CFW.
  • Use reputable tools and sources for your files.
  • Follow instructions carefully and don't rush the process.
  • If you're unsure about anything, ask for help from the community.

Final Thoughts

Updating your Nintendo Switch firmware with a custom firmware installed requires extra care, but the process doesn't have to be intimidating. By backing up your NAND, using tools like ChoiDujourNX, and carefully following instructions, you can keep your Switch up-to-date without losing your homebrew setup. So, go ahead, update your firmware, and enjoy the latest features and games on your hacked Nintendo Switch!
