This page is for existing arm9loaderhax users to update their consoles to boot9strap.

All future releases of Luma3DS will only be made in the .firm format, which will only be compatible with boot9strap and sighax. This means that to continue receiving the latest updates of Luma3DS, you should use this page to update your installation.

::: info

Note that, only on New 3DS, secret_sector.bin is needed to revert the arm9loaderhax exploit, which is why it is not needed for the installation of boot9strap on a stock console. If you do not have a New 3DS, you do not need secret_sector.bin.

Section I - Prep Work

::: info

For all steps in this section, overwrite any existing files on your SD card.

:::

Power off your console
Insert your SD card into your computer
Copy everything from Luma3DS .zip to the root of your SD card
- The root of the SD card refers to the initial directory on your SD card where you can see the Nintendo 3DS folder, but are not inside of it
Copy arm9loaderhax.bin from the v7.0.5 Luma3DS .zip to the root of your SD card
Copy SafeB9SInstaller.bin from the SafeB9SInstaller .zip to the /luma/payloads/ folder on your SD card
- If the luma or payloads folder doesn't exist, create them
- Delete any other existing .bin payloads (GodMode9.bin, Decrypt9WIP.bin, Hourglass9.bin, etc.) in the /luma/payloads/ folder on your SD card as they will not be compatible with boot9strap compatible Luma3DS versions
Create a folder named boot9strap on the root of your SD card
Copy boot9strap.firm and boot9strap.firm.sha from the boot9strap .zip to the /boot9strap/ folder on your SD card
New 3DS Users Only: Copy secret_sector.bin to the /boot9strap/ folder on your SD card

Reinsert your SD card into your console

Section II - Installing boot9strap

Boot your console while holding (Start) to launch SafeB9SInstaller
- If you see the luma configuration screen instead of SafeB9SInstaller, simply press (Start), then shut down your 3DS and try again
- If this gives you an error, try either using a new SD card or formatting your current SD card (backup existing files first)
Wait for all safety checks to complete
- If you get an "OTP Crypto Fail" error, download - aeskeydb.bin, then put it in the /boot9strap/ folder on your SD card and try again
When prompted, input the key combo given on the top screen to install boot9strap
- If a step on the lower screen has red-colored text, and you are not prompted to input a key combo, follow this troubleshooting guide
