[[3DS:GodMode9|GodMode9]] is a full access file browser for the Nintendo 3DS console, giving you access to your SD card, the FAT partitions inside your SysNAND and EmuNAND, and basically anything else. Among other functionality, you can copy, delete, rename files, and create folders.

Note that if you have any payload files other than <code>GodMode9.firm</code> in the <code>/luma/payloads/</code> folder on your SD card, holding {{B|Start}} on boot will display a "chainloader menu" where you will have to use the D-Pad and the {{B|A}} button to select "GodMode9" for these instructions. 

GodMode9 is powerful software that has the capability to modify essentially anything on your console. Though many of these modifications are locked behind a permissions system, and it is impossible to accidentally perform dangerous actions without deliberately unlocking permissions, you should still follow instructions carefully and keep backups just in case.

== Updating GodMode9 ==
{{info|text=Some of the instructions below are only applicable to the latest version of GodMode9, and as such you should follow this section to update your copy before continuing. Overwrite any existing files.}}

=== What You Need ===
* The latest release of {{GitHub|d0k3/GodMode9/releases/latest|GodMode9}} (the GodMode9 <code>.zip</code> file)

=== Instructions ===

# Power off your device
# Insert your SD card into your computer
# Copy <code>GodMode9.firm</code> from the GodMode9 <code>.zip</code> to the <code>/luma/payloads</code> folder on your SD card
#* Make a <code>payloads</code> folder if it doesn't already exist
# Copy the <code>gm9</code> folder from the GodMode9 <code>.zip</code> to the root of your SD card
# Reinsert your SD card into your device

{{success|text=GodMode9 is now up to date.}}

== Creating a NAND Backup ==
# Press and hold {{B|Start}}, and while holding {{B|Start}}, power on your device. This will launch GodMode9
# Press {{B|Home}} to bring up the action menu
# Select "Scripts..."
# Select "GM9Megascript"
# Select "Backup Options"
# Select "SysNAND Backup"
# Press {{B|A}} to confirm
#* This process will take some time
#* If you get an error, make sure that you have at least 1.3GB of free space on your SD card
# Press {{B|A}} to continue
# Press {{B|B}} to return to the main menu
# Select "Exit"
# Press {{B|A}} to relock write permissions if prompted
# Navigate to <code>[S:] SYSNAND VIRTUAL</code>

#* Copy these backups to multiple locations (such as online file storage, an external hard drive, etc.)
#* These backups will save you from a brick and/or help you recover files from the NAND image if anything goes wrong in the future
# Delete <code><date>_<serialnumber>_sysnand_##.bin</code> and <code><date>_<serialnumber>_sysnand_##.bin.sha</code> from the <code>/gm9/out/</code> folder on your SD card after copying it
#* The other backup files are negligible in size and may be kept on your SD card for ease of access
# Reinsert your SD card into your console
