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

Note that, on some versions of Luma3DS, the Luma3DS chainloader menu is only displayed if there is more than one payload detected. If there is only one payload detected, holding (Start) on boot will directly launch GodMode9.

This is powerful stuff, it provides you with the means to do basically any thinkable modification to any system data available on the 3DS console. However, precautions are taken so you don’t accidentally damage the data of your console.
The write permissions system protects you by providing warnings and forces you to enter an unlock sequence for enabling write permissions. It is not possible to overwrite or modify any important stuff without such unlock sequences and it is not possible to accidentally unlock something. As always, be smart, keep backups, just to be safe.

Creating a NAND Backup

Totes noob at 3DS hacking, just installed Soundhax yesterday. Wanting to dump my game carts on to system. I already had Godmode9 in my payloads folder, so when I put Hourglass9 in there too, Godmode9 loaded. Can I only have one payload in there at once, or is there a way of cycling through different payloads when booting to choose which one loads?
Well, today I have tried to install a.3ds file, the Inazuma Eleven Go Galaxy Supernova in english, a translation made by fans, the thing is, when i click to transform it to.cia, it says failed, when I try to encrypt or decrypt, the same, failed. I have a lot of space still, last version of godmode9, no aeskeydb.cin files in 0:/gm9/support.

I have a rom of Xenoblade Chronicles in the 3ds file format. Want to convert it to cia with godmode9. But it's to big for the fat32 formatted SD card. Am I right that I can send it to the 3ds console by using boop on pc? Then convert it to cia via godmode9? Or do I have to use other tools? 1 Overview of Steps 2 What you need 3 Instructions 3.1 Section 1 - Prep Work 3.2 3.3 Section 2 - Updating the System 3.4 Section 3 - Launching FBI 3.5 Section 4 - Installing CIAs 3.6 Section 5 - DSP Dump 3.7 3.8 Section 6 -CTRNAND Luma3DS 3.9 Section 7 - NAND Backup Note: The fileboot.firmis what is launched by boot9strap itself after it finishes loading off of NAND, and can be any valid arm9.

Boot your device while holding (Start) to launch the Luma3DS chainloader menu
Launch GodMode9 by pressing (A)
Press (Home) to bring up the action menu
Select “More…”
Select “Backup NAND”
Press (A) to continue
Hold (R) and press (B) at the same time to eject your SD card
Insert your SD card into your computer
Copy nand.bin from the /gm9out/ folder on your SD card to a safe location on your computer

- Make backups in multiple locations (such as online file storage)
- This backup will save you from a brick if anything goes wrong in the future
Delete nand.bin from the /gm9out/ folder on your SD card after copying it
