OpenFirmInstaller
Safe, simple, user-friendly installer for sighax bootloaders
OpenFirmInstaller is based on SafeB9SInstaller and works the same way as that. All input files go into sdmc:/ofi
. At the present time, only boot9strap and fastboot3DS are supported as input files.
Note to developers: Building this requires firmtool, Python 3.5+ and devkitARM. To compile the CakesROP entrypoint you also need xxd
from the vim
package installed (install it via pacman -S vim
).
Quick Start Guide
For this, we are assuming you already have boot9strap and CFW installed, your 3DS is in working order and you want to switch to fastboot3DS.
- Create a folder called
ofi
on your 3DS SD card. - Download fastboot3DS and copy
fastboot3ds.firm
from the ZIP file toofi/fastboot3ds.firm
on your SD card. - [optional] Get GodMode9 and copy
GodMode9.firm
togm9/payloads/GodMode9.firm
on your SD card. If you are a Luma 3DS user, moveGodMode9.firm
fromluma/payloads/GodMode9.firm
togm9/payloads/GodMode9.firm
. - Copy
OpenFirmInstaller.firm
from the release ZIP to your SD card. If you are a Luma 3DS user, the file goes toluma/payloads/OpenFirmInstaller.firm
. - Run
OpenFirmInstaller.firm
from your SD card. For a Luma 3DS user, thats as simple as holdingSTART
when booting the console and selectingOpenFirmInstaller.firm
when (if) prompted. You may also runOpenFirmInstaller.firm
from GodMode9 (via [A] ->FIRM options...
->Boot FIRM
). - Follow the on screen instructions. When you're asked to input a key sequence to confirm, input the key sequence.
- Done, now fastboot3DS is your bootloader. Further configuration is not required. Your CFW is autobooted as you are used to, and - if you installed it - GodMode9 is booted when you hold START after turning on your console.
OpenFirmInstaller can also work from A9LH systems (you also need to provide secret_sector.bin
then), from unhacked systems on earlier OS versions and via ntrboot cards. Refer to the usual instructions for these special cases. fastboot3DS is highly customizable, you can set boot from CTRNAND, add more payloads via key combos, change splashes (but you absolutely don't have to!). You may enter the fastboot3DS menu by holding HOME when booting.
