If this is your first time modding a 3DS and/or you're unfamiliar with technology, check out [this page](basic-information) for a quick overview of things you may want to know before starting this guide.
{: .notice--info}

Before starting this guide, we will see if custom firmware is already installed and check the current system version of your device.

#### Section I - CFW Check

1. 本体の電源を切ります。
1. Hold the (Select) button
1. Power on your device while still holding the (Select) button
1. If you do not see an unusual menu (e.g. "Luma3DS Configuration"), you may proceed to the next section

If you see an unusual menu, STOP - you already have custom firmware! Continue from [here](checking-for-cfw#what-to-do-next).
{: .notice--warning}

#### Section II - System Version Check

1. Open the System Settings application
1. Your system version will be displayed on the bottom right of the top screen (e.g. "Ver. 11.16.0-49U")

#### Section III - Select a Method

Use the version table below to select a method. A few things to note:
  + The version table below is *inclusive*. For example, "from 11.4.0 to 11.15.0" includes 11.4.0, 11.15.0, and all versions in between.
  + Software versions do not work the same as decimals. Versions 11.10.0 and above are newer than 11.3.0, and are therefore not compatible with Soundhax.
  + The number and letter after the system version are not important.
  + No matter the method you follow, the end result is the same (boot9strap+Luma3DS custom firmware setup on the latest firmware).

#### Alternate Methods

If possible, you should follow one of the software methods listed above.

Otherwise, methods that work on all versions are available, but require additional hardware:

1. [kartdlphax](installing-boot9strap-(kartdlphax)) - requires a second hacked 3DS and a copy of Mario Kart 7
1. [ntrboot](ntrboot) - requires compatible DS flashcart
1. [Installing boot9strap (Hardmod)](installing-boot9strap-(hardmod)) - requires soldering
