#### Instructions

##### Section I - Prep Work

1. Power off your device
1. Insert your SD card into your computer
1. Copy `boot.firm` from the Luma3DS `.7z` to the root of your SD card
1. Copy _the contents of_ the `starter` folder in `starter.zip` to the root of your SD card
1. Create a folder named `boot9strap` on the root of your SD card
1. Copy `boot9strap.firm` and `boot9strap.firm.sha` from the boot9strap `.zip` to the `/boot9strap/` folder on your SD card
1. Copy `arm9.bin` and `arm11.bin` from the SafeB9SInstaller `.zip` to the root of your SD card
1. Reinsert your SD card into your device
1. Power on your device

##### Section II - Launching SafeB9SInstaller

1. Launch the browser and go to the following URL on your device
  + `http://2xrsa.3ds.guide`
  + Jos käytät 2DS:ää tai New 3DS:ää ja langaton yhteys ei ole päällä, saat sen takaisin päälle irrottamalla akun ja laturin muutamaksi sekunniksi, jonka jälkeen voit käynnistää konsolin uudelleen
  + Jos saat virheen "This service is not available in your region", käytä järjestelmäasetuksia (System Settings) asettaaksesi konsolisi maan samaksi kuin CTRTransferilla asentamasi NAND-alue
  + Huomaa, että jos unohdit poistaa lapsilukon käytöstä ennen CTRTransferia tai jos et muuten vain pääse verkkoasetuksiin, konsolisi yhdistää automaattisesti mihin tahansa salasanattomaan verkkoon, jonka nimi on `attwifi`
  + Jos saat jonkin toisen virheen, [seuraa tätä vianmääritysohjetta](troubleshooting#ts_browser)
1. If the exploit was successful, you will have booted into SafeB9SInstaller

##### Section III - Installing boot9strap

1. Wait for all safety checks to complete
1. When prompted, input the key combo given to install boot9strap
1. Once it has completed, press (A) to reboot your device

##### Section IV - Configuring Luma3DS

1. Your device should have rebooted into the Luma3DS configuration menu
  + If you get a black screen, [follow this troubleshooting guide](troubleshooting#ts_sys_b9s)
1. Use the (A) button and the D-Pad to turn on the following:    
  + **"Show NAND or user string in System Settings"**
1. Paina (START)-painiketta tallentaaksesi ja käynnistääksesi uudelleen

___

Note that *New 3DS* users who ended up on 2.1.0 after a CTRTransfer *must* [restore their NAND backup](godmode9-usage#nand_restore) between "Section II - Configuring Luma3DS" and "Section III - Updating the System" of [Finalizing Setup](finalizing-setup).
