<p>Your SD card is most likely acting weird. Try reformatting your SD card (<ahref="formatting-sd-(windows)">Windows</a>, <ahref="formatting-sd-(mac)">macOS</a>, <ahref="formatting-sd-(linux)">Linux</a>). If this doesn’t work, try another SD card.</p>
<p>If your console is on system version 9.4.0, 9.5.0, or 9.6.0, you may be encountering a bug with an old version of universal-otherapp. Download the latest version from <ahref="https://github.com/TuxSH/universal-otherapp/releases/latest">here</a>.</p>
<p>You have the wrong Soundhax file for your console and region, or your console is incompatible with Soundhax. In the latter case, your course of action will determine on what version your 3DS is currently on. 如需帮助，请加入 <ahref="https://discord.gg/MWxPgEp">Nintendo Homebrew Discord 服务器</a>。</p>
<p>Python is not installed on the computer you are using. Download it from the <ahref="https://www.python.org/downloads/">Python website</a>, double-click the installer, and follow the prompts to install Python. Once Python is installed, try again.</p>
<p>If your SD card layout is correct, then your SD card most likely isn’t being read by your console. Re-format it (<ahref="formatting-sd-(windows)">Windows</a>, <ahref="formatting-sd-(linux)">Linux</a>, <ahref="formatting-sd-(mac)">macOS</a>), then start again from the beginning of <ahref="installing-boot9strap-(mset9-cli)#section-i---prep-work">Section I</a>.</p>
<p>Write-protection is enabled on this SD card. If you are using a full-size SD card, ensure that the lock is flipped in the <ahref="/images/sdlock.png">upright position</a>. Otherwise, try ejecting and reinserting your SD card.</p>
<p>You inputted a different number between different runs of MSET9 (for example, you initially selected option 1 for “Old 3DS, 11.8 - 11.17” and then later selected option 2 for “New 3DS, 11.8 - 11.17”).</p>
<p>If this happened when trying to uninstall MSET9, the script has automatically removed MSET9 for you and you can continue to the next page. Otherwise, start again from the beginning of <ahref="installing-boot9strap-(mset9-cli)#section-i---prep-work">Section I</a>.</p>
<p>Copy everything off the SD Card to your PC, re-format it (<ahref="formatting-sd-(windows)">Windows</a>, <ahref="formatting-sd-(linux)">Linux</a>, <ahref="formatting-sd-(mac)">macOS</a>), copy everything back, then start again from the beginning of <ahref="installing-boot9strap-(mset9-cli)#section-i---prep-work">Section I</a>.</p>
<p>Mii Maker data was not found on the SD card. Start again from the beginning of <ahref="installing-boot9strap-(mset9-cli)#section-i---prep-work">Section I</a>.</p>
<li>Write down the first few characters of the folder you see
<ul>
<li>This is your true ID0, which we will keep in the real Nintendo 3DS folder</li>
</ul>
</li>
<li>Delete the ID0 from the current <codeclass="language-plaintext highlighter-rouge">Nintendo 3DS</code> folder</li>
<li>Move the true ID0 folder from the <codeclass="language-plaintext highlighter-rouge">BACKUP_Nintendo 3DS</code> folder to the <codeclass="language-plaintext highlighter-rouge">Nintendo 3DS</code> folder</li>
<li>If it exists, move the <codeclass="language-plaintext highlighter-rouge">Private</code> folder from the <codeclass="language-plaintext highlighter-rouge">BACKUP_Nintendo 3DS</code> folder to the <codeclass="language-plaintext highlighter-rouge">Nintendo 3DS</code> folder</li>
<p>One or more files that MSET9 needs to run is missing or corrupted. Re-download the <ahref="https://github.com/zoogie/MSET9/releases/latest">MSET9 Release <codeclass="language-plaintext highlighter-rouge">.zip</code></a> and extract it to the root of your SD card, replacing all existing files, then try again.</p>
<li>If you haven’t already, press Enter to close the MSET9 script</li>
<li>Insert the SD card into your console</li>
<li>Power on your console</li>
<li>Navigate to System Settings -> Data Management -> Nintendo 3DS -> Software -> Reset (<ahref="/images/screenshots/database-reset.jpg">visual instructions</a>)</li>
<p>This occurs when you use multiple SD cards with the same 3DS and then merge the SD card contents together. Both are “valid”, but the 3DS can only read one at a time.</p>
<p>Now, delete all but one of the folders from your SD card. Generally, you will want to delete the <strong>smallest</strong> one(s), as the one with all your data will probably have more space occupied. You can compare which folder is occupying more space by right-clicking it and clicking “Properties”:</p>
<p>Now, put your SD card into your 3DS and turn it on. If your data is still there, you deleted the right folder and have now determined your correct ID1. If everything has disappeared, go back into the backup folder that you made earlier and try the other folder.</p>
<p>You may be missing <codeclass="language-plaintext highlighter-rouge">SafeB9S.bin</code> from the root of your SD card, or the file may be corrupted. Copy it from the MSET9 <codeclass="language-plaintext highlighter-rouge">.zip</code>, replacing any existing files.</p>
<p>Alternatively, your SD card may be improperly formatted or partitioned. Try reformatting your SD card: <ahref="formatting-sd-(windows)">Windows</a>, <ahref="formatting-sd-(linux)">Linux</a>, <ahref="formatting-sd-(mac)">macOS</a><em>(this will wipe your SD card data)</em></p>
<li><strong>Linux</strong>: open a Terminal window, <codeclass="language-plaintext highlighter-rouge">cd</code> to the root of your SD card, then type <codeclass="language-plaintext highlighter-rouge">python3 mset9.py</code> and press Enter</li>
<li>You should see a window that says “MSET9 … SETUP by zoogie”</li>
<p>If you continue to have this issue and are sure that you did everything correctly, it’s possible that there’s something wrong with your Mii Maker extdata. Follow these instructions to reset it:</p>
<li><strong>Linux</strong>: open a Terminal window, <codeclass="language-plaintext highlighter-rouge">cd</code> to the root of your SD card, then type <codeclass="language-plaintext highlighter-rouge">python3 mset9.py</code> and press Enter</li>
<li>You should see a window that says “MSET9 … SETUP by zoogie”</li>
<li>Type the number corresponding to your console model and version, then press Enter</li>
<li>Type <codeclass="language-plaintext highlighter-rouge">3</code>, then press Enter to remove MSET9</li>
<li>If possible, use a new SD card; otherwise, backup and reformat your existing SD card as FAT32 (<ahref="formatting-sd-(windows)">Windows</a>, <ahref="formatting-sd-(linux)">Linux</a>, <ahref="formatting-sd-(mac)">macOS</a>)</li>
<li>Insert the formatted, blank SD card into your console</li>
<li>Ensure that <codeclass="language-plaintext highlighter-rouge">arm11code.bin</code>, <codeclass="language-plaintext highlighter-rouge">browserhax_hblauncher_ropbin_payload.bin</code>, and <codeclass="language-plaintext highlighter-rouge">boot.3dsx</code> are on the root of the SD card (not inside of any folder)</li>
<li>Ensure that you selected the correct payload for your region AND system version</li>
<li>Ensure that your region settings look <ahref="/images/screenshots/skater_lang.png">like this</a></li>
<li>Try resetting your browser data:
<ol>
<li>打开浏览器，进入浏览器设置页面</li>
<li>Scroll to the bottom and select “Reset Save Data” (it may also be called “Initilize Save Data” or “Clear All Save Data”)</li>
<li>再次尝试触发漏洞</li>

<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>
<p>Ensure that your SD card is not <ahref="/images/sdlock.png">locked</a>. If the SD card is not locked and you continue to get this error, join <ahref="https://discord.gg/MWxPgEp">Nintendo Homebrew on Discord</a> for assistance.</p>
<p>The script has detected that the Nintendo 3DS folder is missing AND that you have already made a NAND backup before. If you intend to install homebrew applications, you should do the following:</p>
<p>You didn’t remove MSET9 when prompted to. Follow Section IV - Removing MSET9 from the <ahref="installing-boot9strap-(mset9-cli)#section-iv---removing-mset9">Windows/macOS/Linux guide</a> or the <ahref="installing-boot9strap-(mset9-play-store)#section-iv---removing-mset9">Android/ChromeOS guide</a>, then re-run the script.</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). 如果你的主机还在用旧版的自制固件（例如基于 arm9loaderhax 或 menuhax 的东西），则你应该在继续操作前先升级自制固件。</p>
<p>这说明你放的 <codeclass="language-plaintext highlighter-rouge">boot.firm</code> 文件有问题。 如果你的主机正在使用 <ahref="https://github.com/SciresM/boot9strap/releases/tag/1.4">boot9strap 1.4</a> 版，那么你的主机在这种情况下开机后，通知灯就会亮起某种特定的颜色，然后关机。 具体亮起的颜色可用来判断你内存卡或主机内存中的 <codeclass="language-plaintext highlighter-rouge">boot.firm</code> 的问题。 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. 主机内存中可以找到 <codeclass="language-plaintext highlighter-rouge">boot.firm</code> 文件，但是文件已损坏。</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>
<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>将 SD 卡上的 <codeclass="language-plaintext highlighter-rouge">Nintendo 3DS</code> 文件夹重命名为 <codeclass="language-plaintext highlighter-rouge">Nintendo 3DS_BACKUP</code>，然后尝试启动主机。 If your console successfully boots, there is some issue within your <codeclass="language-plaintext highlighter-rouge">Nintendo 3DS</code> folder. 尝试清理主菜单的外部存储文件：
<summary><u>"Unable to mount CTRNAND or load the CTRNAND FIRM. Please use an external one."</u></summary>
<p>There are a number of reasons as to why this could be happening. In any case, this error can usually be fixed by following the <ahref="ctrtransfer">CTRTransfer</a> guide.</p>
</details>
<details>
<summary><u>"An error has occurred. Hold down the POWER button to turn off the power..."</u></summary>
You can check if your SD is being read by holding SELECT on boot and checking the yellow text on the bottom screen; if it says “Booted from CTRNAND via B9S”, then your console is booting from the internal memory and not from the SD card.
<li>Power off your console, remove the SD card, insert it on your computer, download the latest release of <ahref="https://github.com/LumaTeam/Luma3DS/releases/latest">Luma3DS</a>, extract <codeclass="language-plaintext highlighter-rouge">boot.firm</code> from the <codeclass="language-plaintext highlighter-rouge">Luma3DS.zip</code> and place it on the root of your SD card (replacing any existing file)</li>

<p>Your console is likely hard-bricked. You will need to buy an ntrboot flashcart to reinstall boot9strap in order to attempt to fix your console. 这也可能是无法修复的硬件问题。 无论如何，请先加入 <ahref="https://discord.gg/MWxPgEp">Nintendo Homebrew Discord 服务器</a> 并说英文求助。（请注意，如果你身处中国大陆，访问 Discord 可能需要科学上网），你也可以到译者的 <ahref="https://stray-soul.site/index.php/qqgroup">QQ 群</a>寻求帮助，群号为 942052497。
+ 还有可能有人设了一个看上去就像变砖了的开机画面。 Try leaving your console powered on, waiting on the blue screen, for five minutes.</p>
<p>Your console is running Luma3DS 6.6 or older, likely via arm9loaderhax. You should follow <ahref="a9lh-to-b9s">A9LH to B9S</a> to update your console to a modern custom firmware environment.</p>

<summary><u>Opening the HOME Menu settings crashes the console or loads the Homebrew Launcher</u></summary>
<p>Your console likely still has menuhax67 installed. To uninstall menuhax67, download the latest release of <ahref="https://github.com/zoogie/menuhax67/releases/latest">menuhax67</a> (the menuhax <codeclass="language-plaintext highlighter-rouge">.zip</code>), then follow the <ahref="https://wiki.hacks.guide/wiki/3DS:Alternate_Exploits/menuhax67#Uninstall_menuhax67">“Uninstall menuhax67” section</a> here.</p>
<p>If you are missing the Homebrew Launcher application from your HOME Menu, you can follow these instructions to manually enter the Homebrew Launcher. (You will need <ahref="https://github.com/LumaTeam/Luma3DS/releases/latest">boot.3dsx and boot.firm</a> on the root of your SD card.)</p>
<li>选择 “Switch the hb. title to the current app.”</li>

<li>If your console is stuck on the loading splash screen, you are missing <codeclass="language-plaintext highlighter-rouge">boot.3dsx</code> from the root of your SD card</li>
<summary><u>Turning off Parental Controls</u></summary>
<p>You can disable the Parental Controls feature by going to System Settings -> Parental Controls and inserting the PIN, then pressing “Clear Settings”, then “Delete” to remove it.
However, if you do not know the PIN and therefore cannot access the console’s settings, you will need to disable it. In order to do this, you need to obtain your console’s master key (mkey):</p>
