Prepare to dedicate at least an hour to thoroughly follow this guide. It’s designed to ensure you carefully read and understand each step for a safe and successful process, safeguarding the longevity of your Switch console. Creating necessary device backups can also take between ten to thirty minutes, depending on your Switch model and microSD card specifications.
Understanding Custom Firmware (CFW) for Nintendo Switch
Custom Firmware (“CFW”) is sophisticated software that modifies your device’s operating system, also known as system firmware. For instance, Atmosphère dynamically patches the Switch OS (Horizon) as it runs.
Think of custom firmware as the ultimate key to unlocking your device’s potential. It grants nearly unlimited control and freedom compared to basic “userland” modifications. This level of access opens up a world of customization and features far beyond the standard user experience.
Exploring Homebrew on Nintendo Switch
Homebrew refers to unofficial software created by enthusiasts for typically locked-down systems, such as the Nintendo Switch. This includes a wide array of creations, from original games and emulators that let you play classics, to save-editing tools and much more. The homebrew scene is vibrant and constantly expanding, offering unique functionalities and entertainment.
On the Switch, CFW is essential for running almost all available homebrew. While some original (“V1”) consoles can run limited homebrew without CFW, all later (“patched”) consoles generally require specialized hardware modifications to enable homebrew access. This guide will focus on CFW installation, the gateway to the vast majority of Switch homebrew.
Custom Operating Systems: Expanding Your Switch’s Capabilities
Custom operating systems (OSes) are alternative system software options, such as Android or Linux, that can be installed alongside your default Switch OS. These are ideal for advanced users who want to push their console beyond gaming, transforming their Nintendo Switch into a versatile hybrid tablet or even a desktop-like environment. Crucially, these custom OSes operate independently from the standard Switch OS. This means actions within a custom OS remain separate and are not reported back to Nintendo, offering a layer of privacy and experimentation. It’s important to understand that custom operating systems are not emulated; they run directly on the Switch’s powerful Tegra X1 System on a Chip (SoC), providing native performance.
This comprehensive Switch Hack Guide offers the option to allocate space on your microSD card for installing these custom OSes, should you choose to explore them. It’s worth deciding early on, as the installation process may involve formatting your microSD card. However, installing a custom OS is entirely optional; you can successfully complete this guide and install Atmosphère CFW without it.
What Will This Switch Hack Guide Install?
The primary goal of this guide is to take an unmodified Nintendo Switch from its factory settings to running custom firmware, specifically Atmosphère. Atmosphère is a leading CFW known for its stability and extensive features, providing a robust platform for homebrew and customization.
fusee-gelee is currently the most prevalent software exploit used to launch custom firmware on the Nintendo Switch. It leverages a vulnerability present in the bootROM of first-generation Switch systems. This vulnerability allows us to bypass Nintendo’s intended boot process and boot the console using any payload we choose. This grants complete, bare-metal control over your console, enabling system storage backups, recovery options, custom firmwares, and custom operating systems. This guide will walk you through using fusee-gelee to unlock the full potential of your V1 Switch, or utilize compatible methods for other models.

These are just some of the highlights. Custom firmware opens up a vast ecosystem of tools and possibilities, continuously expanding thanks to the active Switch homebrew community.
Important Pre-Start Information for Your Switch Hack Journey
As mentioned earlier, completing this switch hack guide requires a minimum of one hour. Please ensure you have allocated sufficient time before beginning. Rushing through the process can lead to mistakes, so patience is key.
It’s crucial to understand that any modification to your system carries a potential risk of an UNRECOVERABLE brick. A bricked device is non-functional, essentially becoming unusable. While bricks are rare on the Switch, they are still a possibility. Therefore, meticulously read and comprehend the instructions before each step, and follow them PRECISELY. This guide is designed to minimize risks, but user error is always a factor.
This switch hack guide is compatible with first-generation (V1) and modchipped Switch consoles across all regions and firmware versions. No matter your current setup, this guide aims to provide a clear path to custom firmware.
To successfully follow this guide, you will need one of the following devices for connectivity:
- A PC: Paired with a USB-C cable capable of data transfer to connect to your Switch. This is the most common and recommended method.
- An Android Device: Along with a USB-C cable that supports data transfer. Note that compatibility may vary depending on the Android device model.
- A Jailbroken iOS Device: Requires a Lightning OTG adapter, a USB cable, and a jailbroken iOS device, all compatible with data transfer. This is a more complex setup and less commonly used.
- A Successfully Modchipped Switch: If your Switch already has a modchip installed, the process will be different and may not require all steps in this guide. Consult your modchip documentation for specific instructions.
If you choose the emuMMC path, which we highly recommend and will introduce later in this guide for safety, you’ll need a microSD card with at least 128 gigabytes of storage. The emuMMC path creates a separate, safe environment for running CFW, minimizing risks to your original system. For this path, it’s essential to disable the Automatic Save Data Cloud function beforehand. Additionally, ensure your Switch is set as the primary console. These steps are crucial for avoiding conflicts and ensuring proper functionality within emuMMC.
For users with smaller microSD cards, the sysCFW path is an alternative, but it comes with increased risks. sysCFW directly modifies your system partition, making it more vulnerable to errors and potential bans if not used carefully. emuMMC is strongly recommended for beginners and for safer long-term use.
Furthermore, on a V1 “unpatched” Switch, you’ll need a method to access Recovery Mode (RCM). This will be explained in detail in the “Entering RCM” section of the guide. While it’s possible to use household items to trigger RCM, a dedicated “jig” is a worthwhile investment for reliable and easy RCM access. Jigs are inexpensive and readily available online, making the process significantly simpler and less prone to error.
Upon successful completion of this switch hack guide, you will not lose any existing data. Your games, Nintendo Account, save files, and personal settings will remain intact. Custom firmware enhances your Switch’s capabilities without erasing your current setup.
Keep your Nintendo Switch plugged in and charging throughout the entire process. This prevents data loss or device damage from an unexpected power outage or battery drain during critical steps.
Custom firmware itself is not permanently installed in the traditional sense. Simply running CFW does not permanently alter your console. CFW is unloaded upon rebooting your Switch back to stock firmware. However, CFW grants the ability to make permanent changes if you choose to do so. Therefore, exercise responsibility and caution with the advanced features enabled by CFW. Always research and understand the potential consequences before making permanent modifications.
It is highly recommended to read this entire switch hack guide from beginning to end at least once before actually performing any steps on your Nintendo Switch. Familiarizing yourself with the process beforehand will significantly reduce the chance of errors and ensure a smoother experience.

Frequently Asked Questions about Switch Hacking
Q: What are the key differences between “first-generation” (“V1”) consoles and “patched” consoles regarding homebrew and CFW?
A: Once you boot into Horizon (the Switch OS) with custom firmware, the differences become minimal in daily use. The primary distinction is that only V1 consoles natively support Atmosphère’s “Reboot to Payload” function, allowing for easier payload injection. Modchips, on the other hand, automatically handle payload loading during reboots on all Switch models. This means V1 consoles have a slight software advantage for payload management, while modchips offer hardware-level convenience across all models.
Q: What exactly is Horizon in the context of Nintendo Switch?
A: Horizon is the official name of the Nintendo Switch operating system. Interestingly, it’s also sometimes referred to as “HorizonNX” because it’s derived from the operating system of the same name used on the Nintendo 3DS. This lineage highlights Nintendo’s continued software evolution across their handheld consoles.
Q: Why is the custom firmware we’re installing called Atmosphère? What’s the significance of the name?
A: The name Atmosphère is derived from the concept that it “runs on top of the Horizon” operating system, much like the Earth’s atmosphere surrounds the planet. Each layer of Horizon’s security architecture is symbolically referenced by the different layers of the atmosphere. For example, the EL1 “kernel” reimplementation within Atmosphère is named mesosphère, while the EL3 “TrustZone” reimplementation is called exosphère. For those interested in the technical details, you can learn more about ARM Exception Levels here.
Q: Can you elaborate on the “emuMMC path” and why a 128GB microSD card is recommended?
A: The primary purpose of emuMMC (emulated MMC) or emuNAND (emulated NAND) is to create a safe and isolated environment for using custom firmware features. It essentially provides an offline clone of your Switch’s internal storage that runs entirely from your microSD card. This separation is crucial for safety and privacy. You’ll need to allocate up to 64GB of space on your microSD card for the emuMMC itself (depending on your internal storage size). Additionally, game installations within emuMMC are stored in a separate Nintendo folder, requiring space for duplicate game data if you intend to play digital games in your emuMMC environment. Hence, a 128GB microSD card is the minimum recommended size to comfortably accommodate the emuMMC partition and game storage. Larger cards are recommended for extensive digital game libraries.
Q: Why is it necessary to set my Nintendo Switch as the primary console before starting this switch hack guide, especially for emuMMC?
A: Setting your Switch as the primary console is important because otherwise, the console will attempt to connect to Nintendo servers to verify licenses before launching applications, including games and homebrew. This online verification process can cause significant delays and even render emuMMC installations unusable. By setting your console as primary, you bypass this online check for locally installed software within your emuMMC, ensuring smooth and uninterrupted operation in your custom firmware environment.
Q: Is it possible to follow this switch hack guide with a microSD card smaller than 128GB? What are the risks of choosing the sysCFW path with a smaller card?
A: Yes, it is technically possible to use a microSD card smaller than 128GB and opt for the sysCFW path. However, it’s generally not recommended, especially for beginners. sysCFW directly modifies your Switch’s system partition, making it riskier. If used incorrectly, running sysCFW can lead to software bricks, requiring more complex recovery procedures, and increases the risk of Nintendo account bans if you connect online carelessly. For first-time CFW users, starting with emuMMC on a 128GB or larger microSD card is strongly advised due to its safety and ease of use. If you understand the risks and are comfortable with potential troubleshooting, sysCFW is an option on smaller cards, but proceed with caution.
Q: Are there any specific restrictions or limitations imposed by Nintendo on consoles running custom firmware and homebrew if I go online?
A: Nintendo’s stance on custom firmware is nuanced. They do not typically ban users solely for the presence of custom firmware on their consoles. Bans are primarily issued for demonstrable misbehavior, such as engaging in piracy (illegally downloading and playing games) or cheating in online multiplayer games. If you use CFW responsibly, avoid piracy and cheating, and take precautions like using emuMMC for potentially risky activities, you are generally treated like any other Nintendo Switch user online. However, it’s essential to understand that any modification carries some risk, and Nintendo’s policies can change. Following best practices and staying informed about community guidelines are crucial for minimizing ban risks.
Q: Where can I find community support and forums if I have questions or encounter issues during the switch hacking process?
A: There are excellent community resources available to assist you! In addition to the official Nintendo Homebrew Discord server, which is a fantastic place to ask questions and get real-time help, you can also explore the r/SwitchHacks subreddit on Reddit. Both platforms are active communities with experienced users and developers who are willing to assist with questions and troubleshooting. These communities are invaluable resources throughout your Switch hacking journey.
