| This page lists possible causes and fixes of Luma3DS exception screens. They are not applicable to every situation, but cover most common known issues.
| | ---- |
| ==Reading a Luma3DS exception screen==
| | the following is a following of the following |
| A Luma3DS exception has four (or five, in a few cases) different parts to it that help in finding its cause, as follows:
| |
| [[File:Luma3DS_exception.png|center]]
| |
| * '''Processor:''' What part of the system is causing the exception. The two processors are:
| |
| **'''Arm9:''' The 'security processor' of the system. These exceptions usually result from 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 often related to broken software or user data.
| |
| * '''Exception type:''' How the system is causing the exception. These categories are often too broad to be helpful, but three of them are more precise:
| |
| **'''data abort''': Oftentimes related to a broken mod or broken HOME Menu data. Occasionally related to custom firmware data being broken.
| |
| **'''prefetch abort (svcBreak)''': Oftentimes an issue with data on the NAND, even when Arm11. Can also happen when launching an out-of-region game.
| |
| **'''undefined instruction''': Usually either a broken piece of software (if not on boot) or outdated <code>boot.firm</code> (if on boot).
| |
| *'''Fault status:''' Why the system is causing the exception. Normally not helpful except for developers.
| |
| *'''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 you last tried to open has an issue.
| |
| **'''nwm''': Networking services, almost always WiFi.
| |
| **'''ns''': The <u>N</u>intendo User Interface <u>S</u>hell, which handles all apps/processes 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 <code>E0E01BF5</code>, <code>boot.firm</code> is guaranteed to be too outdated to work.
| |
|
| |
|
| ==Known Errors==
| | "a following of the following" |
| In the following list, the file prefixes on file paths refer to the starting location. <code>sd:/</code> refers to the SD card, and numbers in the format of <code>[X:]</code> refer to GodMode9's drive numbers.
