<li>If your console is running <em>Luma 10.2.1 or higher</em>, it is <em>100% safe</em> to update. You can check your Luma version by holding (Select) while booting your console.</li>
<li>If your console is on an older Luma version, you should <ahref="checking-for-cfw">update Luma</a> before you update your console to 11.17.0.</li>
<li>If your console does not yet have custom firmware, <strong>do NOT update to the latest version</strong> unless this guide instructs you to. The methods on earlier firmwares are easier and more stable.</li>
<li>If your unmodified console is ALREADY on 11.17.0, this guide has been updated accordingly. Both <ahref="installing-boot9strap-(super-skaterhax)">New3DS</a> and <ahref="installing-boot9strap-(mset9)">Old3DS</a> now have free software methods that (for the most part) do not require external hardware or software.</li>
<pclass="notice--info">If this is your first time modding a 3DS (or you’re unfamiliar with technology), keep reading! Otherwise, if you have prior experience and know what you’re doing, continue to <ahref="get-started">Get Started</a>.</p>
<p>This page covers some of the base computer terminology and 3DS-specific information that you should know before following this guide.</p>

<h2id="things-you-should-know-about-the-3ds">Things you should know about the 3DS</h2>
<p>This guide works with every retail console in the Nintendo 3DS family of consoles (including the 3DS, 3DS XL/LL, 2DS, New 3DS, New 3DS XL/LL, and New 2DS XL/LL), regardless of region or firmware.</p>
<p>In most cases, you can follow this guide as long as you are able to download files from the Internet and copy them to your SD card. Depending on your computer/phone/electronic device, you may need to purchase a USB to SD card adapter to allow your computer to read your SD card.</p>
<p>Some methods (notably, Kartminer7 and MSET9) may require a traditional computer running Windows or Linux. If you are unable to get access to a computer using those operating systems, you will need to follow another method.</p>
<p>The location of the SD card slot and the type of SD card that is accepted depends on the model of your 3DS. More information can be found on <ahref="https://en-americas-support.nintendo.com/app/answers/detail/a_id/271/~/how-to-insert-an-sd-card-or-microsd-card">Nintendo’s official support page</a>.</p>
<p>The 3DS can read SD cards of any capacity (even those larger than 32GB), but the card must be formatted as FAT32 (<strong>not</strong> exFAT or NTFS). You can use one of the following tools to format your SD card, depending on your operating system: <ahref="formatting-sd-(windows)">Windows</a>, <ahref="formatting-sd-(mac)">macOS</a>, <ahref="formatting-sd-(linux)">Linux</a>. SD cards larger than <strong>128GB</strong> are not recommended due to known issues with custom themes and GBA/DS graphics.</p>
<pclass="notice--warning">To follow this guide, you’ll need an SD card with a capacity of at least <strong>2GB</strong>.</p>
<pclass="notice--info">If you want, you can check your SD card for errors before following this guide using <ahref="h2testw-(windows)">H2testw (Windows)</a>, <ahref="f3-(linux)">F3 (Linux)</a>, or <ahref="f3xswift-(mac)">F3XSwift (Mac)</a></p>
<p>By modding your console, you subject it to the remote (but non-zero) possibility of the console being banned from online play or bricked (rendered non-functional). <strong><em>Incorrect file placement will NOT brick your console</em></strong>, but purposely skipping instructions might. Similarly, the last ban wave occurred over five years ago, but there is no guarantee that another one will not occur in the future.</p>
<pclass="notice--warning">Following this guide alone should not result in data loss, but SD card corruption is always a possibility. You should make a backup of your SD card contents (especially the <codeclass="language-plaintext highlighter-rouge">Nintendo 3DS</code> folder) if you have important data.</p>
<p>When copying files to the SD card, it is important to copy them to the right location - otherwise, the console will not detect the file and the exploit or software you are trying to use will not work. A term you will see frequently on this guide is <strong>root of the SD card</strong>, which means you are not inside any folder on your SD card. The directory that appears when you first open your SD card on your computer is called the ‘root’.</p>
<p>You may also see folder names indicated like this: <codeclass="language-plaintext highlighter-rouge">/folder/</code>. The slashes are used to indicate directories and are not part of the name of the folder. For example, <codeclass="language-plaintext highlighter-rouge">/folder1/folder2/</code> would refer to <codeclass="language-plaintext highlighter-rouge">folder2</code> inside of <codeclass="language-plaintext highlighter-rouge">folder1</code>:</p>
<p><strong>Angle brackets</strong> (< and >) are also occasionally used to refer to system-specific identifiers. For example, if the guide says <codeclass="language-plaintext highlighter-rouge"><ID0></code>, it is referring to the system-specific identifier inside of the <codeclass="language-plaintext highlighter-rouge">Nintendo 3DS</code> folder, rather than a folder literally named “ID0”:</p>
<p>In this guide, you will copy files that are downloaded on your computer/phone to your console’s SD card. Many of these files come from GitHub, which is a website used by developers to publish their open-source releases. When downloading files from GitHub, you should download the file that <em>isn’t</em> source code.</p>
<p>Some of the files that you will be asked to download come in the <codeclass="language-plaintext highlighter-rouge">.zip</code> file format, which is used to package multiple files into one file.</p>
<p>When you are told to “copy (file) from (file).zip”, that means that you need to open (or “extract”) the ZIP file. Inside the ZIP file will be the file you’re looking for, after which you can copy it to the specified location on your SD card.</p>
<p>On most operating systems, you can extract files by double-clicking the file. If this doesn’t work, you can install a reputable third-party extraction tool like <ahref="https://7-zip.org/">7-zip</a> instead.</p>
<p>If your computer is running Windows, file extensions may be hidden by default, which may make it harder to find the files you’re looking for. To enable file extensions, follow <ahref="file-extensions-(windows)">these instructions</a>.</p>
