##### Section II - Launching SafeB9SInstaller

1. Launch the browser and go to the following URL on your device
  + `http://2xrsa.3ds.guide`
  + If you are on a New 3DS, New 2DS, or Old 2DS and Wireless Communication is off, you can re-enable the wireless by removing the battery and unplugging the charger for several seconds then booting back up
  + 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. Odota, kunnes kaikki turvatarkistukset on suoritettu
1. Syötä kehotettaessa annettu painikeyhdistelmä asentaaksesi boot9strapin
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
  + If you get an error, just continue the next page

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).
