Whether your Switch can be modified depends on its manufacturing date and which model you own

Not all Nintendo Switches can be modified in the same way. The ability to modify your console depends almost entirely on when it was manufactured. Switches made before mid-2018 are vulnerable to a hardware exploit that allows modification. Switches made after that date have a patched processor and cannot be modified through that same method. The Switch Lite and Switch OLED models, released in 2019 and 2021 respectively, also cannot be modified through publicly known methods.

This matters because modifying your Switch has real consequences. Nintendo actively pursues legal action against people who distribute modification tools and against users who modify consoles to play pirated games. If you modify your Switch and use it online, Nintendo can detect the modification and ban your console from their network permanently. You will lose access to the eShop, online multiplayer, and any digital games tied to your account.

Key Takeaways

  • Only Switch consoles manufactured before mid-2018 can be modified through the publicly known hardware exploit method.
  • Modifying your Switch to play pirated games is illegal in most countries and violates Nintendo's terms of service.
  • Nintendo can detect modified consoles and will permanently ban them from online services, the eShop, and multiplayer.
  • Even if you own a moddable Switch, using it online after modification puts your account and console at risk.

How to check your Switch's manufacturing date

The easiest way to find out when your Switch was made is to look at the serial number on the back of the console. The serial number is printed on a white sticker below the kickstand. It starts with "XAW" followed by 10 digits.

If your serial number starts with XAW1 through XAW4, your Switch was likely manufactured before the patch. If it starts with XAW5 or higher, it was manufactured after the patch and cannot be modified through the known method. However, this is not a may provide — Nintendo changed their manufacturing process partway through some production runs, so the only way to know for certain is to attempt the modification itself or research your specific serial number range online.

What "moddable" actually means

Modifying a Switch typically refers to installing custom firmware that replaces Nintendo's operating system. The most common tool for this is called CFW (custom firmware), which allows you to run unsigned code and bypass Nintendo's security checks. This is different from jailbreaking, which is a term used for phones and tablets.

The hardware exploit that makes early Switches moddable is called the Tegra vulnerability. It exists in the processor itself and cannot be patched through a software update. However, Nintendo fixed it in later production runs by using a different processor revision. Once a Switch has the patched processor, no software method can modify it.

Legal and practical risks of modifying your Switch

Modifying your Switch to play games you own is a gray area legally, but modifying it to play pirated games is illegal in most countries. The Digital Millennium Copyright Act (DMCA) in the United States specifically prohibits circumventing copyright protection measures, which includes the security on the Switch. Other countries have similar laws. Nintendo has sued people who distributed modification tools and has won settlements.

Beyond legal risk, there are practical consequences. If you connect a modified Switch to Nintendo's network, their servers can detect the modification. When they do, they will ban your console's hardware ID permanently. This means that console can never access the eShop, play online multiplayer, or use any online features again. If you have digital games tied to your account, you lose access to them on that console. You cannot undo a ban.

Modifying your Switch also voids your warranty. If something breaks, Nintendo will refuse to repair it. You are also at risk of bricking your console — permanently damaging it — if something goes wrong during the modification process.

Why Nintendo patches consoles and updates the system

Nintendo releases system updates regularly, and one of their purposes is to close security holes that could be used for modification. However, these updates only work on consoles that have not already been modified. If your Switch has already been patched at the hardware level, a system update cannot close the Tegra vulnerability because the vulnerability is in the processor itself, not in the software.

Nintendo's motivation is straightforward: they want to prevent piracy and maintain control over what software runs on their hardware. They also want to protect their online services from cheaters and people using modified consoles to harm other players' experience.

Alternatives if you want to play more games

If you want to expand what you can play on your Switch without modifying it, there are legitimate options. The Nintendo eShop regularly has sales on games, and many older titles cost less than $20. Nintendo Switch Online is a subscription service that gives you access to a library of classic NES and SNES games for about $20 per year.

You can also play games on other platforms. The Steam Deck is a handheld gaming device that runs Linux and can play thousands of games from Steam. Unlike the Switch, it is designed to be modified and customized. If you want to play Nintendo games specifically, you could use an older console like the Wii or GameCube, which have larger libraries of used games available cheaply.

What happens if you sell a modified Switch

If you own a modified Switch and want to sell it, you should be honest about its status. A banned console is worth significantly less than an unmodified one because the buyer cannot use online features. If you sell a modified console without disclosing that it is banned, you are committing fraud.

Some people attempt to sell modified Switches as "unmodified" by restoring the original firmware before sale. However, Nintendo's ban is tied to the hardware itself, not the software, so restoring the firmware does not remove a ban. The console will still be banned when the buyer tries to connect it online.

Frequently Asked Questions

Can I modify my Switch without connecting it to the internet?

Yes, you can modify a moddable Switch and use it entirely offline. However, you will lose access to the eShop, online multiplayer, and any digital games tied to your account. If you ever connect it to the internet after modification, Nintendo will detect it and ban it.

Will a system update remove a modification?

A system update cannot remove a modification if your Switch has the Tegra vulnerability, because the vulnerability is in the hardware. However, updates can break modified consoles or make them unstable. Many people who modify their Switches disable automatic updates.

Is there a way to modify a patched Switch?

Not through publicly known methods. Researchers may discover new exploits in the future, but as of now, Switch consoles manufactured after mid-2018 cannot be modified. The Switch Lite and Switch OLED also have no known public exploits.

Can Nintendo detect modification if I do not go online?

No, Nintendo cannot detect a modification if your Switch never connects to their servers. However, the moment you connect to the internet, their systems will scan for signs of modification and ban your console if they find them.

What is the difference between modifying and hacking?

In common usage, the terms are often used interchangeably for the Switch. Technically, modifying means changing the firmware, while hacking can mean exploiting a security vulnerability. For the Switch, the Tegra exploit is the hack that enables the modification.
