How to show Home Page link in Wordpress Menu and how to add an icon to this?

Question

I tried with this code:

function home_page_menu_args( $args ) {
$args['show_home'] = true;
return $args;
}
add_filter( 'wp_page_menu_args', 'home_page_menu_args' );

but gives me this error: Error 404 - Not Found

I would like that when I click on "Home Page" menu appears the recent posts.
And I would like to place an icon instead of "Home Page" writing.
Thank you!
