== CFW Check ==

# Power on your console while holding the {{B|SELECT}} button

#* If your console boots to the [[3DS:Luma3DS/Configuration|Luma3DS configuration menu]], press {{B|START}} to save, then continue to the CFW troubleshooting section below

#* If your console doesn't boot to the Luma3DS configuration menu, do the same without the SD card inserted

#** If your console does boot to the Luma3DS configuration menu, your SD card wasn't inserted correctly, re-insert it and try again

#** If your console turns off right away, you have CFW and can continue to the CFW troubleshooting section below

#** If your console doesn't boot to the Luma3DS configuration menu but black-screens, your console is likely bricked without CFW, and you should continue to the stock troubleshooting section at the bottom of this page

#*** To make sure of this, hold {{Key press|SELECT|START|X|POWER}} for seven seconds while the console is powered off, then power off again, hold {{B|HOME}}, and then press {{B|POWER}} - if the notification LED [[3DS:boot9strap#LED_Status_Codes|lit up a color]] or the [[3DS:fastboot3DS|fastboot3DS]] menu appears, then you have working CFW but something is interfering with Luma.

== CFW troubleshooting ==

=== Section I - Prep Work ===

# Follow [[3dsguide:restoring-updating-cfw.html|Restoring / Updating CFW]], then "Updating GodMode9" and "Creating a NAND backup" section on [[3DS:GodMode9/Usage]]

# Take out any inserted game cartridge

# Continue to the next section

=== Section II - RTCBug ===

# Power on your console

# Wait ten seconds, then press {{Key press|L|Down|SELECT}} at the same time

#* If the [[3DS:Luma3DS/Rosalina|Rosalina menu]] opens, you're likely experiencing [[3DS:Lumabug|RTCBug]] - return by pressing B, wait 15 minutes, remove any existing cartridge inserted, and the HOME Menu should load on its own. If this doesn't work, continue to the next section

#* If Rosalina doesn't open, continue to the next section

=== Section III - Luma3DS configuration reset ===

# Insert the SD card into your computer

# Navigate to the folder <code>sd:/luma</code>

# Delete <code>config.ini</code>

# Reinsert the SD card into your console

# Power on your console

#* If your console doesn't boot to the Luma3DS config, follow [[SD Clean]], then return to section 2

# Do not enable anything, just press {{B|START}} to save the default configuration

#* If your console boots to the HOME Menu, you should look for and delete faulty patches in <code>/luma/sysmodules</code> and <code>/luma/titles</code> on the SD card before turning <code>Enable game patching</code> or <code>Loading external FIRMs and modules</code> back on

#* If your console doesn't boot to the HOME Menu, continue to the next section

#* If your console boots to an error, check [[3DS:EXCEPTION|the Luma exceptions page]] for how to fix your error, or ask for help in the Nintendo Homebrew Discord if your error isn't listed there

=== Section IV - SD HOME Menu extdata ===

#* If it boots to the Luma3DS configuration screen, press {{B|START}} to save

#* If it doesn't boot to the HOME menu, continue to the next section

#* If it boots to the HOME Menu, do the following steps:

#*# Insert your SD card into your computer

#*# Navigate to <code>Nintendo 3DS</code> -> <code>ID0</code> -> <code>ID1</code> -> <code>extdata</code> -> <code>00000000</code>

#*#* <code>ID0</code> and <code>ID1</code> are 32-character long folders

#*#* If you have multiple ID0/ID1 folders, do the following for all of them

#*# Delete the corresponding folder for your region:  

#*#* USA: <code>0000008f</code>

#*#* EUR: <code>00000098</code>

#*#* JPN: <code>00000082</code>

#*#* KOR: <code>000000A9</code>

#*# Reinsert your SD card into your console

#*# Power on your console

#*#* If it still doesn't boot to the HOME Menu, but does without the SD card, you're experiencing a very weird issue and should ask in the Nintendo Homebrew discord for more advanced help

=== Section V - Safe Mode ===

# Power on your console while holding {{Key press|L|R|Up|A}}

#* If your console boots to the Safe Mode menu, perform the update and see if it boots to the HOME Menu

#* If it doesn't boot to Safe Mode, or doesn't boot to the HOME Menu after a Safe Mode update, continue to the next section

=== Section VI - ctrcheck ===

# Follow the instructions on [[3DS:Ctrcheck|the ctrcheck page]]

# If the console doesn't boot to the HOME Menu after all applicable fixes have been tried, continue to the next section

=== Section VII - New 3DS camera brick{{anchor|Section VIII - New 3DS camera brick}} ===

# Insert your SD card into your computer

# Navigate to the <code>/luma/</code> folder

# Look for <code>errdisp.txt</code>

## If this file already exists, rename it to <code>_errdisp.txt</code>

## If this file doesn't exist, skip to the next section

# Reinsert your SD card into the console

# Power on the console

# Wait 30 seconds without pressing any buttons

# Power off the console

# Navigate to the <code>/luma/</code> folder

# Look for <code>errdisp.txt</code>

#* If this file exists, open it in a text editor, and check if the process name is <code>qtm</code>

#** If the process name is <code>qtm</code>, you need to disconnect your inner camera or replace it

#** If the process name is something else, your console has a very unusual issue and you should ask in the Nintendo Homebrew Discord for more advanced help

#* If this file doesn't exist, continue to the next section

=== Section VIII - CTRTransfer{{anchor|Section VII - CTRTransfer}} ===

# Follow the [[3dsguide:ctrtransfer.html|CTRTransfer guide on 3DS Hacks Guide]]

#* If the console doesn't boot to the HOME Menu at the end of Section III, continue to the next section of this guide

=== Section IX - 3ds_hw_test ===

# Follow the instructions on [[3DS:Hardware test|the hardware test page]]

#* If the number of errors from this is zero, continue to the next section

# Follow [[3DS:CTRTransfer/Manual]]

# Power on your console while holding {{Key press|L|R|Up|A}}

#* If your console boots to the Safe Mode menu, perform the update and see if it boots to the HOME Menu

===Section II - Shutdown menu ===

# Power on the console

# Wait 30 seconds without touching any buttons

# Press the POWER button  

#* If the shutdown menu opens (a grey screen with text), you're experiencing <code>f000000b</code> corruption and must install boot9strap with a [[3DS:ntrboot|ntrboot]] compatible flashcart in order to fix the issue

#* If the screen stays black and the console only powers off if you hold the button for 15 seconds, this may be potentially fixable with ntrboot if it is not a hardware issue
