<p>To install boot9strap on your console, we derive your console’s unique encryption key. To accomplish this, we use a tool called Seedminer to calculate the data encryption key (movable.sed) for your console.</p>
<p>Once we have <codeclass="language-plaintext highlighter-rouge">movable.sed</code>, we can edit the SD card data of the game Mario Kart 7 to install menuhax67, which will allow us to get Homebrew Launcher access.</p>
<p>Once we have Homebrew Launcher access, we can run nimdsphax to install boot9strap.</p>
<p>See <ahref="https://github.com/zoogie/kartminer7">here</a> for information about Kartminer7, <ahref="https://github.com/zoogie/menuhax67">here</a> for information about menuhax67, and <ahref="https://github.com/luigoalma/nimdsphax">here</a> for information about nimdsphax.</p>
