This page lists possible causes and fixes of Luma3DS exception screens. They are not applicable to every situation, but cover most common known issues.
{{User:StarlitSkies/sandbox}}
==Reading a Luma3DS exception screen==
----
A Luma3DS exception has four (or five, in a few cases) different parts to it that help in finding its cause, as follows:
the following is a following of the following
[[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.
**'''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**'''undefined instruction''': Usually either a broken piece of software (if not on boot) or outdated 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. Common or unique processes are as follows:
**'''fs''': Files on your SD card or NAND are having issues.
**'''hid''': Potential hardware problems.
**'''menu''': Some of the data/extdata that's either associated with the HOME Menu or loaded at the same time is broken.
**'''pm''': Almost always, <code>boot.firm</code> is too outdated to work.
**'''loader''': The app you last tried to run has an error.
**'''qtm'''/'''cam''': Your camera has a hardware issue.
**'''nwm''': Your WiFi chip is damaged, dying, or entirely dead. This always means you must disable WiFi to stop the errors.
*'''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"
Note that the prefixes on file paths refer to the starting location. <code>sdmc:/</code> refers to the SD card, and numbers in the format of <code>[X:]</code> refer to GodMode9's drive numbers.
