<h3 id="required-reading">Required Reading</h3>
<p>The file <code class="language-plaintext highlighter-rouge">boot.firm</code> is what is launched by boot9strap itself after it finishes loading off of NAND. In this case, we are using Luma3DS by <a href="https://github.com/LumaTeam/">LumaTeam</a> to patch the device, allowing it to run homebrew software.</p>
<p>On this page, we will make critical system file backups and install the following homebrew programs:</p>
<ul>
<li><strong>FBI</strong> <em>(installs CIA formatted applications)</em></li>
<li><strong>Anemone3DS</strong> <em>(installs custom themes)</em></li>
<li><strong>Checkpoint</strong> <em>(backs up and restores save files for 3DS and DS games)</em></li>
<li><strong>Universal-Updater</strong> <em>(a homebrew app store for downloading homebrew from the 3DS over Wi-Fi)</em></li>
<li><strong>GodMode9</strong> <em>(multipurpose tool which can do NAND and cartridge functions)</em></li>
<li><strong>Homebrew Launcher Loader</strong> <em>(launches the Homebrew Launcher)</em></li>
</ul>
<p class="notice--warning">It is not recommended to skip downloading any of these applications, as many of them will be used later on this page. At the end of this page, your SD card will be cleaned up by removing unnecessary installation files.</p>
<h3 id="compatibility-notes">Compatibility Notes</h3>
<p class="notice--warning">If your <strong>New 3DS</strong> was on version 2.1.0 before following this guide, you should <a href="godmode9-usage#restoring-a-nand-backup">restore your NAND backup</a> before continuing. This likely doesnt apply to you unless you were following this guide in 2017.</p>
<p class="notice--info">If your previous CFW setup was EmuNAND-based and you wish to move the contents of your EmuNAND/RedNAND to SysNAND, follow <a href="move-emunand">Move EmuNAND</a> before following this page. If you dont know what an EmuNAND is, this doesnt apply to you.</p>

<h3 id="instructions">Instructions</h3>
<h4 id="section-i---prep-work">Section I - Prep Work</h4>
<p>In this section, you will copy the files necessary to follow the rest of the instructions on this page.</p>
<ol>
<li>Power off your device</li>
<li>Insert your SD card into your computer</li>
<li>Create a folder named <code class="language-plaintext highlighter-rouge">cias</code> on the root of your SD card if it does not already exist</li>
<li>Copy all of the CIA files (<code class="language-plaintext highlighter-rouge">Anemone3DS.cia</code>, <code class="language-plaintext highlighter-rouge">Checkpoint.cia</code>, <code class="language-plaintext highlighter-rouge">FBI.cia</code>, <code class="language-plaintext highlighter-rouge">Homebrew_Launcher.cia</code>, and <code class="language-plaintext highlighter-rouge">Universal-Updater.cia</code>) to the <code class="language-plaintext highlighter-rouge">/cias/</code> folder on your SD card</li>
<li>Create a folder named <code class="language-plaintext highlighter-rouge">3ds</code> on the root of your SD card if it does not already exist
<ul>
<li>This folder stores homebrew applications and data; it is different from the <code class="language-plaintext highlighter-rouge">Nintendo 3DS</code> folder that the device automatically generates</li>
</ul>
</li>
<li>Copy <code class="language-plaintext highlighter-rouge">FBI.3dsx</code> to the <code class="language-plaintext highlighter-rouge">/3ds/</code> folder on your SD card</li>
<li>Create a folder named <code class="language-plaintext highlighter-rouge">payloads</code> in the <code class="language-plaintext highlighter-rouge">luma</code> folder on your SD card if it does not already exist</li>
<li>Copy <code class="language-plaintext highlighter-rouge">GodMode9.firm</code> from the GodMode9 <code class="language-plaintext highlighter-rouge">.zip</code> to the <code class="language-plaintext highlighter-rouge">/luma/payloads/</code> folder on your SD card</li>
<li>Copy the <code class="language-plaintext highlighter-rouge">gm9</code> folder from the GodMode9 <code class="language-plaintext highlighter-rouge">.zip</code> to the root of your SD card</li>
<li>Reinsert your SD card into your device</li>
<li>Power on your device</li>
</ol>
<p>The screenshots below indicate the minimum SD card layout that is required to follow this page. You may have extra files or folders on your SD card, depending on your previous setup or the method that you followed.</p>

<p class="notice--info"><img src="https://3ds.hacks.guide/images/screenshots/godmode9-location.png" alt="" /></p>
<h4 id="section-ii---updating-the-system">Section II - Updating the System</h4>
<p>In this section, you will update your system to the latest version, which is safe to do with custom firmware.</p>
<ol>
<li>Update your device by going to System Settings, then “Other Settings”, then going all the way to the right and using “System Update”
<ul>
<li>Updates while using B9S + Luma (what you have) are safe</li>
<li>The updater may display a message saying “Your system is up to date” instead of updating. This is normal if you are already up to date; continue to the next section</li>
<li>If this gives you an error, set both your DNS settings and Proxy settings to “Auto”</li>
<li>If this still gives you an error, <a href="troubleshooting#finalizing-setup">follow this troubleshooting guide</a></li>
</ul>
</li>
</ol>
<h4 id="section-iii---homebrew-launcher">Section III - Homebrew Launcher</h4>
<p>In this section, you will temporarily replace Download Play with Homebrew Launcher (which we need to launch FBI). Download Play will automatically go back to normal once you reboot your device.</p>
<ol>
<li>Launch the Download Play application (<img src="https://3ds.hacks.guide/images/download-play-icon.png" alt="" height="24px" width="24px" />)</li>
<li>Wait until you see the <code class="language-plaintext highlighter-rouge">Nintendo 3DS</code> and <code class="language-plaintext highlighter-rouge">Nintendo DS</code> buttons</li>
<li>Press (Left Shoulder) + (D-Pad Down) + (Select) at the same time to open the Rosalina menu</li>
<li>Select “Miscellaneous options”</li>
<li>Select “Switch the hb. title to the current app.”</li>
<li>Press (B) to continue</li>
<li>Press (B) to return to the Rosalina main menu</li>
<li>Press (B) to exit the Rosalina menu</li>
