How To Put CIA On 3DS

The 3DS is one of the most popular gaming systems on the market, with a large library of games from Nintendo, third-party developers, and homebrew developers. However, getting homebrew and third-party games on the 3DS can be a bit tricky. One of the more reliable ways to do this is through the CIA format, which allows you to install files onto your 3DS without using a computer or external device. Here we’ll explain how to put CIA files on a 3DS.

The first step to putting CIA files on a 3DS is to get the game or application in CIA format. This is a proprietary format created and maintained by Nintendo, which allows players to install games directly onto their 3DS without the need for a computer. CIA files can be found on third-party websites, such as 9b and GBATemp, and they can also be generated from downloaded game or application files.

Once you have the CIA file, you will need to install a custom firmware on your 3DS. This is a piece of software which will allow you to run homebrew applications, as well as allowing you to install CIA files. Installing a custom firmware is generally not recommended, as it can void your warranty, but it is necessary if you want to put CIA files on your 3DS.

The next step is to download an Injector, which is a program which allows you to install CIA files without using a computer. There are several reliable Injectors available, the most popular being FBI, which can be found on the 3DS Homebrew website. Once the Injector is installed, you can use it to install the CIA file on your 3DS.

Once the CIA file is installed, it will appear in your game list on the 3DS. From here, you can simply tap the CIA file to launch it and begin playing the game or running the application. It is important to note that not all CIA files will be compatible with your 3DS, so make sure to check to see if the CIA file is compatible before installing it.

Installing CIA files on the 3DS can be a bit of a tricky process, but it is a great way to get access to third-party games and applications. By following these steps, you can easily put CIA files on your 3DS and enjoy a large library of homebrew and third-party content.

Additional Features

In addition to installing CIA files on your 3DS, you can also use custom firmware to enable certain features which are not available on a regular 3DS. These features include the ability to view and edit saved data, edit the region of a game, and install homebrew applications.

The first step to enabling these features is to install a custom firmware, such as Luma3DS or ReiNAND. Once the custom firmware is installed, you will be able to access the features mentioned above. Keep in mind that installing custom firmware can void your warranty, so be sure to research and understand the risks before doing so.

Custom Themes

Custom Themes are an exciting way to customize the look of your 3DS. With custom themes, you can make your 3DS look entirely different, with backgrounds, icons, and even custom music. Custom themes can be found on sites such as GBATemp and 9b, and they are relatively easy to install.

The first step is to download the custom themes, which will come in a zip file. Once the zip file is downloaded, you need to extract it using a file manager, such as BuildServer or a commercial program such as Winzip. Once the contents of the zip file are extracted, you can upload them to the 3DS via FTP or a USB cable.

Once the themes are uploaded, they will be available on the Theme tab of the Home Menu. From here, you can simply select the theme you want to use and it will be applied to your 3DS immediately. Using custom themes is a great way to give your 3DS a unique look and feel.


It is important to create a backup of your 3DS before installing CIA files or custom firmware. This is because installing CIA files and custom firmware can be risky, and if something goes wrong, you will be able to restore your 3DS from the backup. There are several ways to create a backup of your 3DS, including using a USB cable, an SD card, and a PC.

The simplest and most reliable way to create a backup is with a PC. Simply connect your 3DS to your PC and use a program such as Checkpoint to create a full backup. Once the backup is created, you can transfer the backup file to a safe location, such as an external hard drive or cloud storage service.

Creating a backup before installing CIA files or custom firmware is essential if you want to protect your 3DS. In the event that something goes wrong, you can always restore your 3DS and get back to gaming.


When installing CIA files on a 3DS, it is not unusual to run into issues. One of the most common issues is the 3DS not recognizing the CIA file. This can usually be resolved by making sure the CIA file is compatible with your 3DS, as well as making sure that the Injector is installed correctly.

Another common issue is the 3DS not recognizing the custom firmware. This is usually caused by a corrupted firmware file, so you should make sure to reinstall the custom firmware and verify its compatibility with your 3DS. It is also important to make sure that your 3DS is up to date, as older versions may not support custom firmware.

If you are still having issues, it is recommended that you consult a 3DS expert for help. There are several forums dedicated to 3DS customization and homebrew, where you can get help from experienced users. With a little bit of help, you can easily put CIA files on your 3DS and start enjoying homebrew games and applications.
