### Tärkeää tietoa

If you have hacked your 3DS in the past, or you purchased your 3DS second-hand, it is possible that your console already has custom firmware. You should [check for CFW](checking-for-cfw) before proceeding.
{: .notice--warning}

Valitse konsolisi versiota vastaava sivu alta löytyvästä taulukosta. Huomaa, että versionumerot kentissä "versiosta" ja "versioon" ovat sisältyviä.

Järjestelmäsi versio löytyy yläruudun oikeasta alakulmasta järjestelmäasetuksissa (System Settings).

{: .notice--info}

Before starting, you may want to check your SD card for errors using [H2testw (Windows)](h2testw-(windows)), [F3 (Linux)](f3-(linux)), or [F3XSwift (Mac)](f3xswift-(mac))!
{: .notice--warning}

While we believe that custom firmware is safe for online use, there have been online network bans in the past, primarily for cheating and suspicious eShop behavior.
