  1. OpenFirmInstaller

Safe, simple, user-friendly installer for sighax bootloaders

OpenFirmInstaller is based on [SafeB9SInstaller](https://github.com/d0k3/SafeB9SInstaller) and works the same way as that. All input files go into `sdmc:/ofi`. At the present time, only [boot9strap](https://github.com/SciresM/boot9strap) and [fastboot3DS](https://github.com/derrekr/fastboot3DS) are supported as input files.

Note to developers: Building this requires [firmtool](https://github.com/TuxSH/firmtool), [Python 3.5+](https://www.python.org/downloads/) and [devkitARM](https://sourceforge.net/projects/devkitpro/). To compile the CakesROP entrypoint you also need `xxd` from the `vim` package installed (install it via `pacman -S vim`).

    1. 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. 1. Create a folder called `ofi` on your 3DS SD card. 2. Download [fastboot3DS](https://github.com/derrekr/fastboot3DS/releases) and copy `fastboot3ds.firm` from the ZIP file to `ofi/fastboot3ds.firm` on your SD card. 3. [optional] Get [GodMode9](https://github.com/d0k3/GodMode9/releases) and copy `GodMode9.firm` to `gm9/payloads/GodMode9.firm` on your SD card. If you are a [Luma 3DS](https://github.com/AuroraWright/Luma3DS) user, move `GodMode9.firm` from `luma/payloads/GodMode9.firm` to `gm9/payloads/GodMode9.firm`. 4. Copy `OpenFirmInstaller.firm` from the [release ZIP](https://github.com/d0k3/OpenFirmInstaller/releases) to your SD card. If you are a Luma 3DS user, the file goes to `luma/payloads/OpenFirmInstaller.firm`. 5. Run `OpenFirmInstaller.firm` from your SD card. For a Luma 3DS user, thats as simple as holding `START` when booting the console and selecting `OpenFirmInstaller.firm` when (if) prompted. You may also run `OpenFirmInstaller.firm` from GodMode9 (via [A] -> `FIRM options...` -> `Boot FIRM`). 6. Follow the on screen instructions. When you're asked to input a key sequence to confirm, input the key sequence. 7. 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.

This new release greatly simplifies fastboot3DS setup even for novice users. If you had problems with GodMode9 v1.8.0 and Luma 9.1, or if you're just curious, it is suggested you use this release to switch to fastboot3DS now.

Here's a small quick setup guide:

Create a folder called ofi on your 3DS SD card. Download fastboot3DS and copy fastboot3ds.firm from the ZIP file to ofi/fastboot3ds.firm on your SD card. [optional] Get GodMode9 and copy GodMode9.firm to gm9/payloads/GodMode9.firm on your SD card. If you are a Luma 3DS user, move GodMode9.firm from luma/payloads/GodMode9.firm to gm9/payloads/GodMode9.firm. Copy OpenFirmInstaller.firm from the release ZIP to your SD card. If you are a Luma 3DS user, the file goes to luma/payloads/OpenFirmInstaller.firm. Run OpenFirmInstaller.firm from your SD card. For a Luma 3DS user, thats as simple as holding START when booting the console and selecting OpenFirmInstaller.firm when (if) prompted. You may also run OpenFirmInstaller.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. Thanks go to everyone involved in this release, especially to @Wolfvak for Makefile edits, @al3x10m for testing and @luigoalma for memcpy fixes. Also thanks to @profi200 and @derrekr for being great fellow devs.
