1. Espere todos as verificações de segurança finalizarem
1. Quando solicitado, aperte a sequência de botões solicitada para instalar o boot9strap
1. Once it has completed, force your device to power off by holding down the power button
  + Your device will only boot to the SafeB9SInstaller screen until the next section is completed

##### Seção IV - Configurando o Luma3DS

1. Insira o cartão SD no seu computador
1. Delete `boot.firm` from the root of your SD card
1. Copie o `boot.firm` do `.7z` do Luma3DS para a raíz do seu cartão SD
1. Reinsira seu cartão SD no seu dispositivo
1. Ligue o seu dispositivo
1. Seu dispositivo deve ter iniciado no menu de configuração do Luma3DS
  + Se você receber uma tela preta, [siga este guia de troubleshooting](troubleshooting#ts_sys_b9s)
1. Use o botão (A) e os botões direcionais para ativar o seguinte:    
  + **"Show NAND or user string in System Settings"**
1. Aperte (Start) para salvar e reiniciar
  + Se você receber um erro, apenas continue a próxima página

Continue para [Finalizando a instalação](finalizing-setup)
{: .notice--primary}

___

The following are optional sections that will allow you to restore your flashcart to its original state (to allow it to be used for its standard functions).

Note that the Acekard 2i retains its ability to launch `.nds` files while having the ntrboot exploit installed. This only applies when the Acekard 2i is in a 3DS running some kind of custom firmware! While the ntrboot exploit is installed to the Acekard 2i, it will be unable to launch `.nds` files on stock NDS, NDSL, DSi, or 3DS system.

Do not follow any of these sections until you have completed the rest of the instructions on this page.

##### Section V (i) - Removing ntrboot (NDS Flasher)

1. Eject your flashcart from **the target 3DS**
1. Reinsert your flashcart into **the source NDS / NDSL** with the SD card removed
1. Press (Y) to "restore flashrom"
1. Press (B) to "EXIT"

##### Section V (ii) - Removing ntrboot (3DS Multi System)

1. Execute o chainloader do Luma3DS segurando (Start) durante a inicialização do **3DS de origem**
1. Selecione "ntrboot_flasher"
1. Select "Restore Flash"
1. Aperte (Y) para continuar
1. Aguarde até que o processo seja concluído
1. Aperte (B) para retornar para o menu principal
1. Selecione "EXIT" para desligar o **3DS de origem**

##### Section V (iii) - Removing ntrboot (3DS Single System)

###### What you need
