Failed to open SafeB9SInstaller.bin

SafeB9SInstaller.bin 文件丢失或放置在了错误的位置。 下载最新版本的 SafeB9SInstaller 然后解压它，将 SafeB9SInstaller.bin 放在你 SD 卡的根目录中。 如果你下到的东西看不到 .bin 后缀，请不要重命名它。

SigHaxed FIRM was not installed! Check lower screen for more info.

MicroSD Card - init failed

Your SD card is most likely acting weird. Try reformatting your SD card (Windows, macOS, Linux). If this doesn’t work, try another SD card.

SigHaxed FIRM - File not found

你忘记把 boot9strap.firm 和 boot9strap.firm.sha 放进 SD 卡根目录的 boot9strap 文件夹了，或是创建 boot9strap 文件夹的时候打错了名字。 下载最新版本的 boot9strap，然后将 boot9strap.firm 和 boot9strap.firm.sha 放入 boot9strap 文件夹。

SigHaxed FIRM - invalid FIRM

你的 boot9strap.firm 和 boot9strap.firm.sha 文件有问题。 重新下载最新版本的 boot9strap，然后将 boot9strap.firm 和 boot9strap.firm.sha 放入 boot9strap 文件夹。

Secret Sector - File not found

你忘记把 secret_sector.bin 放进 SD 卡根目录的 boot9strap 文件夹了，或是创建 boot9strap 文件夹的时候打错了名字。 使用 BT 客户端下载 secret_sector.bin，然后把它放到 SD 卡里的 boot9strap 文件夹中。

安装 boot9strap（通过 Soundhax）

Red/purple/pink and white screen after running Soundhax

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 here.

If your console is not on those firmwares, it likely indicates that you already have custom firmware. 你应该检查一下。

"An error has occurred, forcing the software to close..." (white message box)

你放的 otherapp.bin 文件有问题（丢失、放错位置或者损坏）。 下载最新版本的 universal-otherapp 并将其放在你 SD 卡的根目录中。

"Could not play"

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 Nintendo Homebrew Discord 服务器。

Failed to mount the SD card!

备份好你 SD 卡上的文件，然后根据你的操作系统选择一个工具来重新格式化 SD 卡为 FAT32 格式：Windows、macOS、Linux。 目前已知 MiniTool Partition Wizard 和惠普格式化工具（HPUSBDisk）格出来的 SD 卡给 3DS 使用会出问题。

如果还是不行，尝试换一张 SD 卡。

Installing boot9strap (MSET9)

Python 3 is not installed

Python is not installed on the computer you are using. Download it from the Python website, double-click the installer, and follow the prompts to install Python. Once Python is installed, try again.

Error 01: Couldn't find Nintendo 3DS folder

You are not running MSET9 from the root of the SD card, or the SD card is missing the Nintendo 3DS folder.

Remember, your SD card should look like this:

MSET9 root layout

If your SD card layout is correct, then your SD card most likely isn’t being read by your console. Re-format it (Windows, Linux, macOS), then start again from the beginning of Section I.

Error 02: Your SD is write protected

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 upright position. Otherwise, try ejecting and reinserting your SD card.

Error 03: Don't change console version

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”).

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 Section I.

Error 04: No HOME Menu Extdata.

Your SD card is not formatted properly.

Copy everything off the SD Card to your PC, re-format it (Windows, Linux, macOS), copy everything back, then start again from the beginning of Section I.

Error 05: No Mii Maker Data!

Mii Maker data was not found on the SD card. Start again from the beginning of Section I.

Error 06: You need at least 16MB free

Your SD card does not have enough space to trigger MSET9. Free up some space and try again.

At the end of this guide, you will need at least 1.3GB to make a NAND backup, so it’s best to free up at least that much.

Error 07: You don't have 1 ID0, you have (#)!

You have multiple ID0 folders. To determine the correct folder, follow these instructions:

  1. 将 Nintendo 3DS 文件夹重命名为 BACKUP_Nintendo 3DS
  2. Reinsert your SD card into your console
  3. Power on your console
  4. Wait for the console to generate the SD card data
    • 你先前安装的程序会暂时消失。 这是正常的，且接下来就会还原回来。
  5. 将主机关机
  6. 将你的 SD 卡插入到电脑
  7. 打开你 SD 卡的 Nintendo 3DS 文件夹
  8. Write down the first few characters of the folder you see
    • This is your true ID0, which we will keep in the real Nintendo 3DS folder
  9. Delete the ID0 from the current Nintendo 3DS folder
  10. Move the true ID0 folder from the BACKUP_Nintendo 3DS folder to the Nintendo 3DS folder
  11. If it exists, move the Private folder from the BACKUP_Nintendo 3DS folder to the Nintendo 3DS folder

Once you’ve done this, continue from Section I Step 7.

Error 08: One or more files are missing or malformed!

One or more files that MSET9 needs to run is missing or corrupted. Re-download the MSET9 Release .zip and extract it to the root of your SD card, replacing all existing files, then try again.

Error 10: Database(s) malformed or missing!

This happens when no valid title database is present, usually because you never installed any titles from eShop on this SD card.

  1. If you haven’t already, press Enter to close the MSET9 script
  2. Insert the SD card into your console
  3. Power on your console
  4. Navigate to System Settings -> Data Management -> Nintendo 3DS -> Software -> Reset (visual instructions)
  5. 将主机关机
  6. Insert the SD card into your computer
  7. Return to Section I Step 7
Error 12: You don't have 1 ID1, you have (#)!

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.

You will need to determine which one contains your data. First of all, back up all of the folders, in case something goes wrong:

Backup ID1

Now, delete all but one of the folders from your SD card. Generally, you will want to delete the smallest 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”:

Properties prompt

Which to delete

Your SD card should now look something like this:

Just enough ID1s

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.

Red screen after reinserting SD card (Section II Step 11)

You may be missing SafeB9S.bin from the root of your SD card, or the file may be corrupted. Copy it from the MSET9 .zip, replacing any existing files.

Alternatively, your SD card may be improperly formatted or partitioned. Try reformatting your SD card: Windows, Linux, macOS (this will wipe your SD card data)

System Settings loading infinitely after reinserting the SD card

You most likely did something different from the MSET9 instructions, or selected the wrong model or version.

  1. Close the script window
  2. Execute the mset9.py script on the root of the SD card
    • Windows: Double-click mset9.bat
    • Linux: open a Terminal window, cd to the root of your SD card, then type python3 mset9.py and press Enter
    • You should see a window that says “MSET9 … SETUP by zoogie”
  3. Type the number corresponding to your console model and version, then press Enter
  4. Type 3, then press Enter
  5. Once the window says “Successfully removed MSET9!”, reinsert the SD card into your console
  6. Power on your console
  7. Return to Section II Step 1

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:

  1. Close the script window
  2. Run the MSET9 script
    • Windows: Double-click mset9.bat
    • Linux: open a Terminal window, cd to the root of your SD card, then type python3 mset9.py and press Enter
    • You should see a window that says “MSET9 … SETUP by zoogie”
  3. Type the number corresponding to your console model and version, then press Enter
  4. Type 3, then press Enter to remove MSET9
  5. If possible, use a new SD card; otherwise, backup and reformat your existing SD card as FAT32 (Windows, Linux, macOS)
  6. Insert the formatted, blank SD card into your console
  7. Return to Section I Step 1

After finishing the MSET9 page, you should switch back to your old SD card before continuing to Finalizing Setup.

An exception occured after triggering MSET9

这可能代表着你的主机已经安装过了自制固件。 你应该检查一下。

Boot issues on consoles with custom firmware

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。

Power/notification light indicators

My console powers off when I try to turn it on, and/or the notification LED shows a color on boot

这说明你放的 boot.firm 文件有问题。 如果你的主机正在使用 boot9strap 1.4 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 boot.firm 的问题。 On older versions of boot9strap, the blue light will power off almost immediately when trying to turn on the console.

如果通知灯亮起：

  • White: Your 3DS was not able to find boot.firm on your SD card or on internal memory.
  • Magenta: Your 3DS was not able to find boot.firm on your SD card. 主机内存中可以找到 boot.firm 文件，但是文件已损坏。
  • Red: Your 3DS was able to find boot.firm on both your SD card and on internal memory, but both files are corrupted.

你可以通过下载 最新版本的 Luma3DS，然后解压，将 boot.firm 复制到 SD 卡的根目录。 如果 boot.firm 始终被主机判定为损坏，则你可能需要使用一个工具来测试一下你的 SD 卡（Windows、Linux、macOS） 另外，最好不要使用 WinRAR 解压文件，解压的文件给 3DS 使用可能会出问题。

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.

My console gets stuck on a black screen with blue power light staying on

你可以把下面所列出的方法都试试，此处将方法从最省时到最耗时的顺序排列。

  1. Power off your console, remove the SD card, re-insert it, then power on your console.
  2. 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
  3. 将 SD 卡上的 Nintendo 3DS 文件夹重命名为 Nintendo 3DS_BACKUP，然后尝试启动主机。 If your console successfully boots, there is some issue within your Nintendo 3DS folder. 尝试清理主菜单的外部存储文件：
    • 进入到 /Nintendo 3DS/<ID0>/<ID1>/extdata/00000000/
    • 删除对应你的 3DS 区域的文件夹：
      • 欧版: 00000098
      • 日版: 00000082
      • 美版: 000008f
      • 中国版（神游版）: 000000A1
      • 韩版: 000000A9
      • 台湾版: 000000B1
  4. 尝试启动到恢复模式并升级系统：
    • Power off your console
    • 按住 “L” + “R” + “↑” + “A” 四个键
    • Power on your console
    • If you were successful, the console will boot to an “update your system” screen
  5. 尝试做 CTRTransfer
  6. 如需援助，请加入 Nintendo Homebrew Discord 服务器并使用英文求助。（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 QQ 群 寻求帮助，群号为 942052497。

Error message on boot

"An error has occurred: Failed to apply 1 FIRM patch(es)" or "An exception has occurred -- Current process: pm"

你主机的 Luma3DS 版本已过时。 下载最新版本的 Luma3DS 并将 boot.firm 放在你 SD 卡的根目录中，如有存在相同文件请替换。 请不要用 WinRAR 解压 ZIP 文件，我们目前已知这会导致与 3DS 有关的文件出错。

"Unable to mount CTRNAND or load the CTRNAND FIRM. Please use an external one."

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 CTRTransfer guide.

"An error has occurred. Hold down the POWER button to turn off the power..."

ARM11 异常处理器已被禁用，或主机未安装自制固件。 尝试启用 ARM11 异常处理器： + Power off your console + 按住 “Select” 键 + Power on your console, while still holding (Select) + 如果 “ARM11 exception handlers disabled” 已被勾选，则请取消勾选它

HOME Menu is missing installed applications

This could be caused by various reasons, but most likely because your SD card is not being read by the system. 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. If this is the case, attempt the steps below, which are listed from easiest to hardest:

  1. Power off your console, remove the SD card, re-insert it, then power on your console
  2. Power off your console, remove the SD card, insert it on your computer, download the latest release of Luma3DS, extract boot.firm from the Luma3DS.zip and place it on the root of your SD card (replacing any existing file)
  3. Power off your console, remove the SD card, insert it on your computer and reformat your SD card according to your computer’s operating system: Windows, macOS, Linux (this will wipe your SD card data)
  4. Test your SD card for errors by following the guide according to your computer’s operating system: Windows, Linux, macOS. If your SD card is marked as faulty, then you will have to replace your SD card
  5. Your SD card slot may be broken. Join Nintendo Homebrew on Discord for further assistance
Blue "BOOTROM ERROR" screen

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 Nintendo Homebrew Discord 服务器 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 QQ 群寻求帮助，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.
