Seedminer

Mehrere Ordner mit langem Namen im Nintendo 3DS Ordner

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. Um herauszufinden, welcher der langen Ordner der richtige ist, folge diesen Anweisungen:

  1. Benenne den Nintendo 3DS Ordner zu BACKUP_Nintendo 3DS um
  2. Reinsert your SD card into your console
  3. Power on your console
  4. Wait for the console to generate the SD card data
    • Deine Apps werden verschwunden sein. Das ist normal und wird gleich behoben
  5. Power off your console
  6. Stecke deine SD-Karte in deinen Computer
  7. Navigiere zum “Nintendo 3DS”-Ordner auf deiner SD-Karte
  8. Kopiere den 32 Buchstaben langen Ordnernamen von dem Ordner, den du siehst
  9. Lösche den Nintendo 3DS Ordner
  10. Benenne den BACKUP_Nintendo 3DS Ordner zu Nintendo 3DS um
Bruteforce Movable springt zu Schritt 4

Die Webseite hat deine movable.sed mit deiner Freundescode- und ID0-Kombination bereits herausgefunden. Du kannst die movable.sed Datei benutzen, die dir die Seite gibt.

Important! You have been locked out of the automated part1 dumper system...

Dein Freundescode wurde von dem Bot blockiert, da dein 3DS es nicht geschafft hat, den Bot als Freund hinzuzufügen. Stell sicher, dass dein 3DS korrekt mit dem Internet verbunden ist, und bitte in Nintendo Homebrew on Discord auf Englisch um eine Entperrung.

We were unable to successfully complete your bruteforce request. :`(

Die Webseite hat festgestellt, dass deine movable.sed nicht brute-forcebar ist. Stell sicher, dass du der Seite die richtige ID0 gegeben hast. If your ID0 is correct, then you will be unable to use Seedminer and you will have to use an alternate method.

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 Homebrew Launcher (super-skaterhax). Otherwise, you will need to follow a method that requires additional games or hardware.

BannerBomb3

Multiple ID1 folders inside of ID0

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.

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 Nintendo DSiWare folder in the one that remains and move F00D43D5.bin to that location.

DSiWare Management Menü stürzt ab, ohne BB3 multihax menu anzuzeigen

Stelle sicher, dass F00D43D5.bin die einzige Datei in Nintendo 3DS -> <ID0> -> <ID1>-> Nintendo DSiWare` ist. Falls ja, dann erstelle sie mit dem Bannerbomb3 Injektor erneut.

Stelle außerdem sicher, dass bb3.bin im Stammverzeichnis der SD-Karte liegt. Wenn es fehlt, dann lade die neuste Version von Bannerbomb3 herunter (direkter Download) und kopiere die bb3.bin Datei in das Stammverzeichnis deiner SD-Karte.

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. Wenn das der Fall ist, trete dem Nintendo Homebrew on Discord Server bei und frage, auf Englisch, nach Hilfe.

Nintendo DSiWare-Datenverwaltung zeigt "Es wurden keine Softwaredaten gefunden."

F00D43D5.bin fehlt in Nintendo 3DS -> <ID0> -> <ID1> -> Nintendo DSiWare. Stelle sicher, dass Nintendo DSiWare korrekt geschrieben und Leerzeichen enthält. Groß-/Kleinschreibung spielt hierbei keine Rolle.

Nintendo DSiWare-Datenverwaltung zeigt ein Fragezeichen

Möglicherweise gibt es ein Problem mit deiner F00D43D5.bin Datei (sie kann beschädigt oder für den falschen 3DS bestimmt sein). Erstelle deine F00D43D5.bin Datei mit dem Bannerbomb3 Injector neu, und stelle sicher, dass du die movable.sed Datei für deine Konsole benutzt.

Sichere deine Daten und formatiere deine SD-Karte als FAT32 mit dem empfohlenen Werkzeug je nach Betriebssystem (Windows, macOS, Linux). MiniTool Partition Wizard und das HP Formatierungswerkzeug (HPUSBDisk) sind bekannt für Probleme mit 3DS SD-Karten.

Wenn dies nicht gelingt, benutze eine andere SD-Karte.

boot9strap installieren (Fredtool)

Error bei der Fredtool Injector Seite

Stelle sicher, dass deine movable.sed und das DSiWare-Backup von derselben Konsole stammen. Eine Unterschied führt zu einem Fehler.

"Haxxxxxxxxx!" ist nicht auswählbar, da das BB3 multihax menu erscheint

Du hast vergessen F00D43D5.bin von der SD-Karte zu löschen. Navigiere zu Nintendo 3DS -> <ID0> -> <ID1> -> Nintendo DSiWare auf deiner SD-Karte und lösche die F00D43D5.bin Datei.

Homebrew Launcher (PicHaxx)

"An error has occurred. Hold down the POWER button to turn off the power..." (black screen with text)

Your 00000001.sav and/or otherapp.bin files may be misplaced. Ensure that 00000001.sav is in Nintendo 3DS -> <ID0> -> <ID1> -> title -> 00040000 -> 0017c100 -> data and that otherapp.bin is on the root of your SD card.

If your files are in the correct locations, re-create the save using the PicHaxx Save Tool, then place it in Nintendo 3DS -> <ID0> -> <ID1> -> title -> 00040000 -> 0017c100 -> data. Ensure that the file is named exactly 00000001.sav and that you used your console’s movable.sed to create it. Re-download otherapps.zip, place the .bin file relevant to your console to the root of your SD card, and rename it to otherapp.bin. Füge die .bin Erweiterung nicht hinzu, wenn du sie noch nicht siehst.

"An exception occurred" or Errdisp when opening Picross

Your console already has custom firmware. You should check for CFW.

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

There is an issue with your otherapp.bin file. Download otherapps.zip, place the .bin file relevant to your console to the root of your SD card, and rename it to otherapp.bin. Füge die .bin Erweiterung nicht hinzu, wenn du sie noch nicht siehst.

Game starts normally

Your modified 00000001.sav file may be misplaced, or you may have used the wrong movable.sed when creating it. Re-generate your movable.sed from Bruteforce Movable, then re-create the save using the PicHaxx Save Tool and place the resulting file (00000001.sav) in Nintendo 3DS -> <ID0> -> <ID1> -> title -> 00040000 -> 0017c100 -> data.

Installing boot9strap (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. You should check for CFW.

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

There is an issue with your otherapp.bin file (it is missing, misplaced, or corrupted). Download the latest release of universal-otherapp and place it on the root of your SD card.

"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, you should update your console to the latest version and follow Seedminer.

Failed to open SafeB9SInstaller.bin

Die Datei SafeB9SInstaller.bin fehlt oder ist falsch platziert. Lade die neueste Version von SafeB9SInstaller herunter, entpacke sie und platziere SafeB9SInstaller.bin im Stammverzeichnis deiner SD-Karte. Füge die .bin Erweiterung nicht hinzu, wenn du sie noch nicht siehst.

Failed to mount the SD card!

Sichere deine Daten und formatiere deine SD-Karte als FAT32 mit dem empfohlenen Werkzeug je nach Betriebssystem (Windows, macOS, Linux). MiniTool Partition Wizard und das HP Formatierungswerkzeug (HPUSBDisk) sind bekannt für Probleme mit 3DS SD-Karten.

Wenn dies nicht gelingt, benutze eine andere SD-Karte.

Installing boot9strap (SSLoth-Browser)

Red/purple/pink and white screen after running Browserhax

This likely indicates that you already have custom firmware. You should check for CFW.

"An error has occurred. Hold down the POWER button to turn off the power..." (black screen with text)

The file arm11code.bin is missing or misplaced. Lade die neuste Version von universal-otherapp herunter, platziere otherapp.bin im Stammverzeichnis deiner SD-Karte und benenne die Datei zu arm11code.bin um. Füge die .bin Erweiterung nicht hinzu, wenn du sie noch nicht siehst.

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

Opening the browserhax QR code or URL crashes

Browser based exploits (such as this one) are often unstable and crash frequently, but they can sometimes be fixed by doing the following steps.

  1. Launch the browser, then launch the browser settings
  2. Scroll to the bottom and Initialize Savedata (it also may be called Clear All Save Data)
  3. Try the exploit again
System Update prompt when opening browser

The SSLoth proxy was incorrectly configured. Re-do the SSLoth section on the page.

Error 032-0420 when opening browser

Follow these steps in order:

  1. Launch System Settings on your console
  2. Navigate to Internet Settings -> Connection Settings
  3. Click on your network connection slot and navigate to Change Settings -> Next Page (right arrow) -> Proxy Settings
  4. Set “Proxy Settings” to “No”
  5. Click OK, then click Save
  6. When prompted, click “Test” to perform the connection test
    • Der Test sollte erfolgreich sein
  7. Click “OK” to continue
  8. Press “Back” twice, then “Close” to go back to the HOME Menu
  9. Open the Internet Browser once
  10. If prompted about a system update, press OK
    • This won’t actually update the system
  11. Start again from Section II
"To use the Internet Browser, please update your system using the System Update option in the System Settings."

First, make sure you entered the correct proxy for the connection you’re using. If not, go back to Section II. If the proxy is correct, then your console has been cart-updated, which means an alternate exploit will need to be used.

Method 1
If the two numbers before the region in the system version string is equal to or less than 36 (e.g. Ver. 11.14.0-36U), you can follow Soundhax. When prompted to select a firmware to generate the sound file, use:

  • 1.x - 2.1 if the number is between 0 and 2
  • 2.1 - 2.2 if the number is between 3 and 4
  • 3.x - 4.x if the number is between 5 and 10
  • 5.x - 11.3 if the number is between 11 and 36

Method 2 (Old 3DS only)
If you have an Old 3DS / Old 3DS XL / 2DS, you can try a Safe Mode update, which will trigger an alternate exploit:

  1. Ensure that the proxy that you used for SSLoth is still actively applied to your internet connection
  2. With your console powered off, hold the following buttons: (Left Shoulder) + (Right Shoulder) + (D-Pad Up) + (A), and while holding these buttons together, power on your console
    • Keep holding the buttons until the console boots into Safe Mode (a “system update” menu)
  3. Drücke “OK” um das System-Update zu bestätigen
  4. If everything worked correctly, the update will fail and the 3DS will boot into SafeB9SInstaller. If it did, then continue from Section IV.

If these methods didn’t work (or do not apply to you), update your console to the latest version and follow Seedminer.

Failed to open SafeB9SInstaller.bin

Die Datei SafeB9SInstaller.bin fehlt oder ist falsch platziert. Lade die neueste Version von SafeB9SInstaller herunter, entpacke sie und platziere SafeB9SInstaller.bin im Stammverzeichnis deiner SD-Karte. Füge die .bin Erweiterung nicht hinzu, wenn du sie noch nicht siehst.

Frozen on "Doing agbhax..."

There may be an issue with your arm11code.bin file. Re-download the latest release of universal-otherapp, place it on the root of your SD card, and rename it to arm11code.bin. Füge die .bin Erweiterung nicht hinzu, wenn du sie noch nicht siehst.

If you have a Taiwanese unit (with a T in the version string, ie. 11.3.0-##T), you will not be able to follow these instructions, and you will need to update your console and follow Seedminer instead.

If you have a Mainland Chinese unit (with a C in the version string, ie. 11.3.0-##C), join Nintendo Homebrew on Discord for assistance.

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). 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.

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

There is an issue with your boot.firm file. If you’re running boot9strap 1.4, your 3DS notification LED may flash a certain color. This color is used to diagnose issues involving your boot.firm 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.

If the notification LED flashes:

  • 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. It was able to find boot.firm on internal memory, but the file is corrupted.
  • Red: Your 3DS was able to find boot.firm on both your SD card and on internal memory, but both files are corrupted.

You can get a new boot.firm file by downloading the latest release of Luma3DS, extracting it, and placing boot.firm on the root of your SD card. If your boot.firm file is consistently being detected as corrupted, you may want to check your SD card for errors (Windows, Linux, or macOS). Also, note that the 3DS tends to have issues with files extracted using WinRAR.

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

The steps below can be attempted in any order, but are listed from least to most time-consuming.

  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. Rename the Nintendo 3DS folder on your SD card to Nintendo 3DS_BACKUP, then attempt to boot. If your console successfully boots, there is some issue within your Nintendo 3DS folder. Try clearing HOME Menu extdata:
    • Navigate to /Nintendo 3DS/<ID0>/<ID1>/extdata/00000000/ + Delete the corresponding folder for your 3DS region:
      • EUR-Region: 00000098
      • JPN-Region: 00000082
      • USA-Region: 0000008f
      • CHN-Region: 000000A1
      • KOR-Region: 000000A9
      • TWN-Region: 000000B1
  4. Try booting into recovery mode and updating your system:
    • Power off your console
    • Hold (Left Shoulder) + (Right Shoulder) + (D-Pad Up) + (A)
    • Power on your console
    • If you were successful, the console will boot to an “update your system” screen
  5. Follow the CTRTransfer guide
  6. For further support, ask for help at Nintendo Homebrew on Discord

Error message on boot

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

Your Luma3DS version is outdated. Download the latest release of Luma3DS and place boot.firm on the root of your SD card, replacing any existing file. Make sure you are extracting the ZIP file with any tool other than WinRAR, as it is known to cause issues with 3DS-related files.

"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 exception handlers are disabled, or custom firmware is not installed. Try enabling ARM11 exception handlers:

  • Power off your console
  • Hold (Select)
  • Power on your console, while still holding (Select)
  • If the “Disable ARM11 exception handlers” box is checked, uncheck it
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 PC, 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 PC 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. This may also indicate a hardware issue that cannot be fixed. In any case, join Nintendo Homebrew on Discord for assistance.

  • It is also possible that someone has set a boot-time splash screen that just looks like a brick. Try leaving your console powered on, waiting on the blue screen, for five minutes.
Some other error

Please take a photo of the error and join Nintendo Homebrew on Discord for assistance.
