Key information

This page lists possible causes and fixes of Luma3DS exception screens, ErrDisp screens, stock error codes, and bootROM errors. They are not applicable to every situation, but cover most common known issues.

In the following lists, the file prefixes on file paths refer to the starting location. sd:/ refers to the SD card, and numbers in the format of [X:] refer to GodMode9's drive numbers.

If your ErrDisp displays one of the processes in the first table, you do not need to look up its error code in the second one. The solutions for these processes are almost always the same.

On both stock and custom firmware, apps can cause error codes if they run into a non-fatal issue.
In the below tables, error codes are separated into sets by their section (e.g. 007-XXXX) and then sorted within their sets in ascending order by their result code (e.g. XXX-2001).

OOjs UI icon information-progressive.svg Not all 3DS error codes are known or understood, and it is unlikely all codes will ever be documented in full due to Nintendo failing to document many of them.
OOjs UI icon information-progressive.svg If the below fixes do not solve your issue or you are unsure of what to do, join the Nintendo Homebrew Discord for further assistance.

Known errors


Error On Boot

Exception Type Problem & Solution
Any Files on the SD are corrupted.
To fix, verify that your SD card is not faulty. If it is verified working, make a backup of all intact files, format the SD card, and try booting again.
A system save located on the NAND in [1:]/data has a problem.
System-unique files are missing from the NAND in [1:]/rw/sys.
data abort The shared2 folder in [2:] SYSNAND TWLN is missing.
To fix, create this folder.
System titles have been deleted.
To fix, perform a Safe Mode update.
If this does not work, perform a CTRTransfer.
prefetch abort (svcBreak) The system movable, [1:]/private/movable.sed, is 288 bytes but a flag is enabled that expects a size of 320 bytes.
To fix, boot into GodMode9 and select SYSNAND CTRNAND, then go into the private folder.
Inside this folder, you will see a file named movable.sed. Select it, and under the options menu, select Show in Hexeditor.
Green-colored numbers will appear in the middle of the screen - press A and then unlock writing to sysNAND (lvl2).
At the beginning of the file, look for the set of numbers 53 45 45 44 00 01. Once you find these numbers, hold A and press D-PAD DOWN while the 01 value is highlighted to change it to 00. Press B, then A, then B to save changes and exit from the hexeditor, then press START to reboot your console.
SYSNAND CTRNAND has bad CMACs.
To fix, press R+A on the SYSNAND CTRNAND drive and Fix CMACs for drive. The console will act like it has been formatted after this, and this is intended.
If none of the above fixes worked, perform a Manual CTRTransfer.
prefetch abort (kernel panic) The console likely has a hardware issue.
undefined instruction The console likely has a hardware issue.

Error During Use

Exception Type Problem & Solution
data abort Files on the SD are corrupted.
To fix, verify that the SD card is not faulty. If it is verified working, make a backup of all intact files, format the SD card, and try again.

Error On Boot

Current Process Exception Type Problem & Solution
act any Your NNID(s)' stored data is misconfigured or being interfered with.
To fix, if Pretendo is installed, turn it off by disabling Enable loading external FIRMs and modules on the Luma configuration menu.
If this does not help or Pretendo is not installed, then restore a NAND backup - especially if you recently tried to log out an NNID.
boss data abort The current firmware version is too old for SpotPass to work. Perform a Safe Mode update.
If this does not work, you may require a CTRTransfer.
camera any Potential hardware issues, or an instance of ShutTheCamUp is crashing.
Look for and delete /luma/sysmodules/0004013000001602.ips and /luma/titles/0004013000001602/code.ips.
If this fixed the issue, then update Luma3DS and reinstall the correct Old or New 3DS patch for ShutTheCamUp if you wish to continue using it.
If these don't exist, or the error occurs when booting without an SD card, it's likely hardware issues. Join the Nintendo Homebrew Discord and ask, in English, for help.
cfg any Either the NAND config savegame or part of your console-unique file(s) is damaged.
To fix, first boot into GodMode9, press R+A while the cursor is on the folder [1:]/data/<ID0>/sysdata/00010017, choose to Copy to 0:/gm9/out, then delete the folder. After rebooting, the console will enter initial setup again; this is intended and not an issue.
If this does not help, delete the newly created 00010017 and copy the backup into its place, run 3DS:ctrcheck, and replace any console-unique files marked as invalid or missing with the copies from the essentials.exefs backup inside [S:] SYSNAND VIRTUAL in GodMode9.
fs any Can be anything from SD card problems to hardware issues.
Fault isolation will likely be required to find the true cause of this error. Start by doing ctrcheck and trying to trigger the error with the SD card removed from the console.
If the error stops when the SD card is removed, reformat the SD card, and if that doesn't help, test it for hardware damage.
hid any Potential hardware problems, or an instance of rehid is crashing.
First look for and delete /luma/titles/0004013000001D02, /luma/titles/0004013000003302, /luma/sysmodules/0004013000001D02.cxi and /luma/sysmodules/0004013000003302.ips.
If this fixed the issue, then update Luma3DS and reinstall the latest release of rehid to continue using it.
If these don't exist, or rehid has never been installed on this console, it's likely hardware issues. 3ds_hw_test or ctrcheck may help with fault isolation.
i2c, gsp, mcu, pxi, spi any The console has a serious hardware issue that likely is not easily fixable.
Run 3ds_hw_test.
If the test returns zero errors detected, join the Nintendo Homebrew Discord and ask, in English, for help.
mset any System Settings is broken in some way - this may indicate that the console has a hardware issue.
To fix, perform a CTRTransfer, or a Manual CTRTransfer if that does not work.
If neither of these work, the console has a serious issue. Join the Nintendo Homebrew Discord and ask, in English, for help.
menu data abort Broken HOME Menu theme.
To fix, go into the folder sd:/Nintendo 3DS/<ID0>/<ID1>/extdata/00000000/ and delete the folder matching your region, one of the following:
USA: 000002cd
EUR: 000002ce
JPN: 000002cc
Broken HOME Menu extra data.
To fix, go into the folder sd:/Nintendo 3DS/<ID0>/<ID1>/extdata/00000000/ and delete the folder matching your region, one of the following:
USA: 0000008f
EUR: 00000098
JPN: 00000082
KOR: 000000A9
Broken HOME Menu application.
To fix, either perform a Safe Mode update, attempt to enter System Settings before the crash occurs and delete the application in Data Management, or reformat the SD card.
prefetch abort An installation of Menuhax is conflicting with the custom firmware.
To fix, follow the directions on this page.
If this occurs on boot, set Hbmenu autoboot in the Luma configuration menu to 3DS, then follow the above instructions and turn Hbmenu autoboot back off once it has been removed.
Ensure in sd:/luma/config.ini that hbldr_3dsx_titleid is set to 000400000d921e00 and boot.3dsx is in the root.
prefetch abort (svcBreak) If R5 contains D900458B: The f000000b folder in SYSNAND CTRNAND is broken, its exact location being at [1:]/data/<ID0>/extdata/00048000/f000000b.
To fix, backup f000000b by pressing R+A while highlighting it, then selecting Copy to 0:/gm9/out. Once it is backed up, delete the folder. If this does not fix the issue, copy the folder back where it was.
System titles are missing. Perform a Safe Mode update.
If you have a recent NAND backup, you could try restoring it instead with this guide
ns prefetch abort (svcBreak) The Luma configuration setting Hbmenu autoboot is set to boot to a title that does not exist.
To fix, disable the option, install an application with the title ID in sd:/luma/config.ini, or change the set title ID to match an application that does exist.
nwm any The WiFi chipset's hardware is damaged or dead.
To fix, replace the WiFi chipset with a new one. To avoid the error until then, disable WiFi on the 3DS and do not turn it back on.
If the 3DS is an old model, you can disable WiFi using an external switch. New models do not have this switch disable it through the HOME Menu Settings or Rosalina. Repeatedly pressing the keycombo for Rosalina while powering on might let you access Rosalina before it can crash.
pm undefined instruction The installed version of Luma3DS likely does not support the current firmware version. This is guaranteed to be true if the contents of R0 are E0E01BF5.
To fix, update CFW.

Error During Use

Current Process Exception Type Problem & Solution
3dsx_app any The .3dsx file that was most recently opened is corrupted.
To fix, download a new copy of the .3dsx file. If this error happens when opening the Homebrew Launcher, download a new copy of boot.3dsx.
If the error still happens, test the SD card for errors.
app
CtrApp
prefetch abort (svcbreak) The app most recently opened is out-of-region and relies on locale-specific data. Activate locale emulation for it.
any other process The app most recently opened is trying to use broken software.
To fix, disable all game mods, cheat codes, and plugins to ensure they are not the cause.
If the error still happens, then the game itself is likely faulty. If it is a system app, perform a CTRTransfer. Otherwise, if it is a cartridge dump, redump it, if it is an eShop game, click the Repair button at the bottom of its eShop page or delete and reinstall it, or if it is a cartridge, clean the cartridge and the 3DS cartridge reader with isopropyl alcohol.
GARDEN any Animal Crossing's game data or savedata is having issues.
To fix, disable all game mods, cheat codes, and plugins to ensure they are not the cause. If the error still happens, then the game itself may be faulty. If it is a cartridge dump, redump it, if it is an eShop game, click the Repair button at the bottom of its eShop page or delete and reinstall it, or if it is a cartridge, clean the cartridge and the 3DS cartridge reader with isopropyl alcohol.
If the error yet still happens, ensure that you have not used a save editor before the error started happening. If you have used a save editor, the edits are broken and you will need to restore a backed-up save, or wipe the save and start over if you have no backup.
fs any Can be anything from SD card problems to hardware issues.
fault isolation will likely be required to find the true cause of this error. Start by doing ctrcheck and trying to trigger the error with the SD card removed from the console.
If the error stops when the SD card is removed, reformat the SD card, and if that doesn't help, test it for hardware damage.
Kujira
Joker
niji_loc
any The app most recently opened has an issue of some kind.
To fix, disable all game mods, cheat codes, and plugins to ensure they are not the cause. If the error still happens, ensure the game is the same region as the console - if it is not, activate locale emulation for the game.
If the error yet still happens, then the game itself is likely faulty. If it is a cartridge dump, redump it. If it is an eShop game, click the Repair button at the bottom of its eShop page or delete and reinstall it. If it is a cartridge, clean the cartridge and the 3DS cartridge reader with isopropyl alcohol.
loader undefined instruction The app most recently opened has an issue. R0 is (most likely) an error code. Here are some common values for R0:
D9004587: When trying to open a game: The game is corrupted, or it's seed is not imported.
See: 3DS:Fixing corrupted games
C8804478: If trying to open the Homebrew Launcher: boot.3dsx is missing from the root of your SD card.
To fix: Download the latest Homebrew Launcher from here
D96077FA/FFFFFFFF: The .3dsx that Luma3DS tried to load is corrupted.
To fix, redownload the app you are trying to launch. If this happens when you try open the Homebrew Launcher itself, see the error above.
Most of the other possible error codes for this are listed on this page.
prefetch abort (svcBreak) The LayeredFS or sysmodule patch Luma3DS tried to load is invalid or corrupt.
To fix: Re-download any recently installed patches (eg. Nimbus (Pretendo), Wumiibo, or anything else that goes in /luma/titles or /luma/sysmodules.) Alternatively, you may disable loading external FIRMs and modules as well as Enable game patching in the Luma3DS configuration menu.
mset any System Settings is broken in some way - this may indicate that the console has a hardware issue.
To fix, perform a CTRTransfer, or a Manual CTRTransfer if that does not work.
If neither of these work, the console has a serious issue. Join the Nintendo Homebrew Discord and ask, in English, for help.
nwm any The WiFi chipset's hardware is damaged or dead.
To fix, replace the WiFi chipset with a new one. To avoid the error until then, disable WiFi on the 3DS and do not turn it back on.
If the 3DS is an old model, you can disable WiFi with an external switch. New models must instead disable it through the HOME Menu Settings or Rosalina. Repeatedly pressing the keycombo for Rosalina while powering on might let you access Rosalina before it can crash.
pxi any Could be anything from a faulty cartridge to damaged internal components, but will almost always be some type of hardware issue.
qtm
cam
any The camera's hardware is damaged or dead.
To fix, replace the camera with a new one. To avoid the error until then, disconnect the camera or avoid using anything that activates the camera.
swkbd any The software keyboard is broken in some way - this may indicate that the console has a hardware issue.
To fix, perform a CTRTransfer, or a Manual CTRTransfer if that does not work.
If neither of these work, the console has a serious issue. Join the Nintendo Homebrew Discord and ask, in English, for help.

ErrDisp

Process Name Problem & Solution
process: cam
process: qtm
Your camera's hardware is damaged or dead.
If the error code is 0xF96183FE, you can open sd:/luma/config.ini and set the variable enable_safe_firm_rosalina to 1 to bypass this error.
Otherwise, to fix, replace the camera with a new one. To avoid the error until then or if you cannot get a new camera, disconnect the camera.
process: kernel Your system software is having a strange issue.
To fix, diagnose further by reading the contents of the file sd:/luma/errdisp.txt. If you do not understand this file, join the Nintendo Homebrew Discord and explain your issue there.
process: nwm Your WiFi chipset's hardware is damaged or dead.
To fix, replace the WiFi chipset with a new one. To avoid this error until then or if you cannot get a new chipset, disable WiFi on the 3DS and do not turn it back on.
If your 3DS is an old model, you can disable WiFi with an external switch. New models must instead disable it through the HOME Menu Settings or Rosalina. Repeatedly pressing the keycombo for Rosalina while powering on may allow you to access Rosalina before it can crash.
process: mcu Something related to power or the battery is having issues.
To fix, check if your charger repeatedly disconnects and reconnects while it is inserted. If this is the case, you have a faulty charger port and need to replace it.
If this is not the case, you have a deeper hardware issue that may not be fixable.
OOjs UI icon information-progressive.svg In the following table, when ? is in an error code, it is a wildcard.
This means any character can be in its position and the error code will remain the same.
Error Code Problem & Solution
card removed Your SD card is faulty, or debris is interfering with its connection to the 3DS.
To fix, clean the SD card and the SD reader in the 3DS with isopropyl alcohol. If this does not work, test the SD card for errors.
0xC8A11BEF Occurs when attempting to use DLP services with an out-of-region game. This issue is not fixable currently.
0xC86044D2 Your NAND does not have enough free space available.
To fix, join the Nintendo Homebrew Discord and explain your issue in detail. Deleting files from the NAND without guidance is likely to cause additional issues.
0xC8804478 The app you tried to open or system software it relies on is missing.
If this occurs when you open any DS game or DS Download Play, follow TWLFix.
If this occurs after doing a manual CTRTransfer, Lazarus3DS, or the nim module errors, check in GodMode9 whether the file path 1:/private/movable.sed exists. If it does not, you will need to manually restore movable.sed from a backup. Join the Nintendo Homebrew Discord and ask for help with this.
0xC8804464
0xC8804471
0xC8804497
0xC88044A?
Some dependency of the app you are trying to open does not exist.
Ensure your SD is inserted, especially if the code is C88044AB specifically. If it is, ensure you have all of the necessary files for what you are trying to do.
If you do have the files and it is happening to a digital title, do a Safe Mode update.
If you do have the files and it is happening to a cartridge, either your 3DS or the cartridge likely has a hardware issue.
0xC8A04573 Your SD card is formatted strangely.
To fix, reformat the SD card. If this does not work, test the SD card for errors.
0xC8A0802B If this happened while installing an application, your title.db does not exist or is corrupted.
To fix, follow one of the two following sets of instructions. The second one will delete all installed games/apps as a side effect, but is significantly faster and simpler.
  1. rebuild title.db and then try again.
  2. Open GodMode9, go into the file path 1:/dbs/ and delete any existing title.db, then press R+Y, choose Create a dummy file, and name this file title.db - leave the file size at 0. Once the file is created, press START to reboot, go into System Settings -> Data Management -> Nintendo 3DS -> Software, and choose Yes if a prompt about management information appears.
0xC92044EB
0xC92044FA
0xC960454?
Your SD card is set to read-only or is faulty.
To fix, make sure the slider on the left side of the SD card is pushed up, use a different SD adapter if you are currently using one, and test the SD for errors if it is not read-only.
If the error is happening when launching a cartridge, especially if the error code is 0xC960454?, delete any updates or DLC to see if the cartridge works as they could be corrupt or faulty. If this succeeds, reinstall them from eShop and ensure the cartridge still works.
If the error still happens, the SD card is likely faulty. If it is also read-only, it has permanently protected itself to prevent data corruption. Either way, back up its contents and get a new SD.
0xD8E0806A You have developer UNITINFO enabled and are trying to install a retail game.
To fix, go into the file sd:/luma/config.ini and set the variable use_dev_unitinfo to 0.
0xD860446? You are attempting to use more processing power than the console currently has available.
To fix, ensure you are not using a mod that is designed for an emulator rather than native hardware. If you are using such a mod, either toggle off any "Extra RAM" setting or use a different mod.
0xD900458? The app you tried to open, its savedata, or an update file for it is corrupted.
To fix, if it is a cartridge dump, redump it. If it is an eShop game, click the Repair button at the bottom of its eShop page or delete and reinstall it. If it is a cartridge, clean the cartridge and the 3DS cartridge reader with isopropyl alcohol.
0xF9605002 If attempting to use any camera features, your camera hardware is damaged or dead.

Reading error screens

Reading a Luma3DS exception screen

Luma3DS exception.png

A Luma3DS exception has four (or five, in a few cases) different parts to it that help in finding its cause, as follows:

  • Processor: What part of the system is causing the exception. The two processors are:
    • Arm9: The 'security processor' of the system. These exceptions are usually raised because of errors in NAND data or hardware faults in either the 3DS or its SD card.
    • Arm11: The 'userland' of the system. These exceptions have numerous causes but are more often related to broken software or user data.
  • Exception type: The type of fault that caused the exception. These categories correspond to the ARM exceptions for the ARM9 and ARM11 CPUs, as follows:
    • data abort: Caused by a read or write to an invalid part of memory. Usually related to game mods/cheats/plugins, broken HOME Menu data, and/or broken CFW applications.
    • prefetch abort: Caused by an attempt to execute an invalid CPU instruction. Often related to conflicts between CFW and other software.
    • prefetch abort (svcBreak): Caused by either Process9 or homebrew software manually terminating code because it matched a pre-defined condition. Often related to errors in NAND data, even when raised by Arm11. Can also happen when launching an out-of-region game that isn't locale emulated.
    • prefetch abort (kernel panic): Caused by Kernel9 detecting an unrecoverable fatal error and forcibly shutting down to avoid damage. Can be related to any of several things, but hardware issues are the most likely.
    • undefined instruction: Caused by an attempt to execute a CPU instruction that was unimplemented, disallowed, or unusable. Often related to software not having the required files (if not on boot) or an outdated boot.firm (if on boot).
  • Fault status: The specific type of ARM exception that was raised. Helpful for developers, but not so much for the end user.
  • Current process: Where the error is coming from in the system. Often the most helpful part of the exception. Some examples of processes are as follows:
    • fs: The filesystem, i.e. either the SD card or the NAND.
    • menu: Data that is opened either as a part of the HOME Menu or at the same time as it.
    • loader: The service that opens apps, meaning the app most recently opened has an issue.
    • nwm: Networking services, almost always Wi-Fi.
    • ns: The Nintendo User Interface Shell, which handles all apps/processes/services in 3DS mode.
  • R0: Usually just internal data that's not worth reading. There are two notable exceptions, however:
    • Arm11 loader exception: If R0's contents start with a C or D, R0 is an error code. This code usually gives the exact cause of the issue.
    • Arm11 pm exception: If R0's contents are E0E01BF5, boot.firm is guaranteed to be too outdated to work.

Reading a Luma3DS ErrDisp

Luma3DS ErrDisp.jpg

A Luma3DS ErrDisp error has several parts, but only two of them help in finding its cause. They are as follows:

  • Process name: The part of the system that is triggering the error. Can be helpful if the error code is generic.
  • Error code: The specific reason the error occurred. This is almost always the most helpful part of the error.

Reading an error code

3DS error code.jpg
An error code has two parts - the code itself, and its official description.

For this page, only the code matters

Reading boot9strap LED status codes

Booting your console while holding X+START+SELECT, or if either FIRM file is corrupt, the notification LED will display a color indicating the status of the FIRMs located at sdmc:/boot.firm and nand:/boot.firm. Refer to the following table for their status:

Color SD FIRM CTRNAND FIRM
Green Loaded -
Yellow Missing Loaded
Orange Corrupt Loaded
White Missing Missing
Magenta Missing Corrupt
Red Corrupt Corrupt/Missing

In addition, the LED will blink if booting from ntrboot
NOTE: A red LED status can also occur if the NAND firm is missing rather than corrupt.
