<summary><u>Multiple long folder names in Nintendo 3DS folder</u></summary>
<p>This occurs when you use your SD card in multiple 3DS consoles and is intended to prevent inadvertently merging data that would not be valid on other consoles. To figure out which long folder name is correct for your 3DS, follow these instructions:</p>
<li>Rename the <codeclass="language-plaintext highlighter-rouge">Nintendo 3DS</code> folder to <codeclass="language-plaintext highlighter-rouge">BACKUP_Nintendo 3DS</code></li>
<li>Navigate to the <codeclass="language-plaintext highlighter-rouge">Nintendo 3DS</code> folder on your SD card</li>
<li>Copy the 32 character long name of the folder you see
<ul>
<li>This is your true ID0 that you will use in <ahref="seedminer#section-ii---seedminer">Section II of Seedminer</a></li>
</ul>
</li>
<li>Delete the <codeclass="language-plaintext highlighter-rouge">Nintendo 3DS</code> folder</li>
<li>Rename the <codeclass="language-plaintext highlighter-rouge">BACKUP_Nintendo 3DS</code> folder to <codeclass="language-plaintext highlighter-rouge">Nintendo 3DS</code></li>

<summary><u>Bruteforce Movable skips to step 4</u></summary>
<p>The website has already mined your <codeclass="language-plaintext highlighter-rouge">movable.sed</code> using your friend code and ID0 combination. You can use the <codeclass="language-plaintext highlighter-rouge">movable.sed</code> that it provides you.</p>
</details>
<details>
<summary><u>Important! You have been locked out of the automated part1 dumper system...</u></summary>
<p>Your friend code was blocked from using the friend code bot because your 3DS did not successfully friend the bot. Ensure your 3DS is properly connected to the Internet, then join <ahref="https://discord.gg/MWxPgEp">Nintendo Homebrew on Discord</a> and ask to be unlocked.</p>
</details>
<details>
<summary><u>We were unable to successfully complete your bruteforce request. :`(</u></summary>
<p>The website has determined that your <codeclass="language-plaintext highlighter-rouge">movable.sed</code> cannot be brute-forced. Ensure that you gave the correct ID0 to the website. If your ID0 is correct, then you will be unable to use Seedminer and you will have to use an alternate method.</p>
<p>If you have a New 3DS / New 3DS XL / New 2DS XL (as indicated by the four shoulder buttons on the back and the C-Stick on the right), you can follow <ahref="homebrew-launcher-(super-skaterhax)">Homebrew Launcher (super-skaterhax)</a>. Otherwise, you will need to follow a method that requires additional games or hardware.</p>
<p>This can occur if you’ve used multiple SD cards on a 3DS and then merged the contents of the SD cards together. This is done to prevent conflicting, valid data from being merged together.</p>
<p>To fix this, you will need to determine which folder contains your data. Usually, this will be the larger (or largest) of the folders. Backup and delete the smaller one(s), then create a <codeclass="language-plaintext highlighter-rouge">Nintendo DSiWare</code> folder in the one that remains and move <codeclass="language-plaintext highlighter-rouge">F00D43D5.bin</code> to that location.</p>
</details>
<details>
<summary><u>DSiWare Management menu crashes without showing BB3 multihax menu</u></summary>
<p>Ensure that <codeclass="language-plaintext highlighter-rouge">F00D43D5.bin</code> is the only file in <codeclass="language-plaintext highlighter-rouge">Nintendo 3DS</code> -><codeclass="language-plaintext highlighter-rouge"><ID0></code> -><codeclass="language-plaintext highlighter-rouge"><ID1></code> -><codeclass="language-plaintext highlighter-rouge">Nintendo DSiWare</code>. If it is, then re-create it with the <ahref="http://3dstools.nhnarwhal.com/#/bb3gen">Bannerbomb3 Injector</a>.</p>
<p>Also, ensure that <codeclass="language-plaintext highlighter-rouge">bb3.bin</code> is on the root of the SD card. If it is missing, then download the latest release of <ahref="https://github.com/lifehackerhansol/Bannerbomb3/releases/download/v3.0-lhs1/bb3.bin">Bannerbomb3</a> (direct download), and copy the <codeclass="language-plaintext highlighter-rouge">bb3.bin</code> file to the root of your SD card.</p>
<p>If neither of these solutions fixes this problem, then custom firmware may have been uninstalled on this console in a way that makes this method impossible to perform. If this is the case, join <ahref="https://discord.gg/MWxPgEp">Nintendo Homebrew on Discord</a> and ask, in English, for help.</p>

<p>There may be an issue with your <codeclass="language-plaintext highlighter-rouge">F00D43D5.bin</code> file (it may be corrupted or intended for the wrong 3DS). Re-create your <codeclass="language-plaintext highlighter-rouge">F00D43D5.bin</code> file with the <ahref="http://3dstools.nhnarwhal.com/#/bb3gen">Bannerbomb3 Injector</a>, ensuring that you use the <codeclass="language-plaintext highlighter-rouge">movable.sed</code> file for your console.</p>

<p>If you have enough space on your SD card, your SD might be corrupted or faulty. Check your SD card for any errors by following the guide according to your computer’s operating system: <ahref="h2testw-(windows)">Windows</a>, <ahref="f3-(linux)">Linux</a>, <ahref="f3xswift-(mac)">macOS</a>.</p>
<pclass="notice--info">The steps detailed here generally assume that your console has a modern custom firmware setup (boot9strap + Luma3DS 8.0 or greater). If your console is running an older homebrew setup (for example, something based on arm9loaderhax or menuhax), you should update your setup before trying these instructions.</p>
<p>There is an issue with your <codeclass="language-plaintext highlighter-rouge">boot.firm</code> file. If you’re running <ahref="https://github.com/SciresM/boot9strap/releases/tag/1.4">boot9strap 1.4</a>, your 3DS notification LED may flash a certain color. This color is used to diagnose issues involving your <codeclass="language-plaintext highlighter-rouge">boot.firm</code> file on SD card or internal memory. On older versions of boot9strap, the blue light will power off almost immediately when trying to turn on the console.</p>
<li><strong>White</strong>: Your 3DS was not able to find <codeclass="language-plaintext highlighter-rouge">boot.firm</code> on your SD card or on internal memory.</li>
<li><strong>Magenta</strong>: Your 3DS was not able to find <codeclass="language-plaintext highlighter-rouge">boot.firm</code> on your SD card. It was able to find <codeclass="language-plaintext highlighter-rouge">boot.firm</code> on internal memory, but the file is corrupted.</li>
<li><strong>Red</strong>: Your 3DS was able to find <codeclass="language-plaintext highlighter-rouge">boot.firm</code> on both your SD card and on internal memory, but both files are corrupted.</li>
</ul>
<p>You can get a new <codeclass="language-plaintext highlighter-rouge">boot.firm</code> file by downloading the <ahref="https://github.com/LumaTeam/Luma3DS/releases/latest">latest release of Luma3DS</a>, extracting it, and placing <codeclass="language-plaintext highlighter-rouge">boot.firm</code> on the root of your SD card. If your <codeclass="language-plaintext highlighter-rouge">boot.firm</code> file is consistently being detected as corrupted, you may want to check your SD card for errors (<ahref="h2testw-(windows)">Windows</a>, <ahref="f3-(linux)">Linux</a>, or <ahref="f3xswift-(mac)">macOS</a>). Also, note that the 3DS tends to have issues with files extracted using WinRAR.</p>
<p>If you hear a “popping sound”, potentially accompanied with the backlight turning on for a split second, there is a hardware issue with your console (such as a disconnected backlight cable). You may be able to get your console to boot by holding it at certain angles.</p>
<li>Power off your console, remove the SD card, re-insert it, then power on your console.</li>
<li>Power off your console, eject the game cartridge if inserted, power on your console, then wait up to ten minutes. If your console boots within ten minutes, the issue has been fixed and is unlikely to reoccur</li>
<li>Rename the <codeclass="language-plaintext highlighter-rouge">Nintendo 3DS</code> folder on your SD card to <codeclass="language-plaintext highlighter-rouge">Nintendo 3DS_BACKUP</code>, then attempt to boot. If your console successfully boots, there is some issue within your <codeclass="language-plaintext highlighter-rouge">Nintendo 3DS</code> folder. Try clearing HOME Menu extdata:
<li>Follow the <ahref="ctrtransfer">CTRTransfer</a> guide</li>
