I’m browsing between pages on Windows Phone 8.1 using the following call:
ShowViewModel<DetalheViewModel>();
When I click the button come back the app closes. How do I implement the back button feature?

The ideal would be to create a class called Baseview (or something like that) that extends to Mvxwindowspage and inherit your views from this Baseview, not Mvxwindowspage.
Your Baseview class would look something like this:
public class BaseView : MvxWindowsPage
{
public BaseView()
{
HardwareButtons.BackPressed += HardwareButtons_BackPressed;
}
private void HardwareButtons_BackPressed(object sender, BackPressedEventArgs e)
{
if(Frame.CanGoBack)
{
e.Handled = true;
Frame.GoBack();
}
}
}
You could also create a baseViewModel and put a command to it (Gobackcommand) and, instead of calling Frame.Goback(), call something like this:
var vm = ViewModel as MyBaseViewModel;
if (vm != null)
{
e.Handled = true;
vm.GoBackCommand.Execute(null);
}
Both forms are correct and work.
Which in my Classlibrary is the reference for Hardwarebuttons ? I can’t add the reference to Windows.Phone.UI
No, that’s in your Windows Phone project. Views are specific, so they don’t enter the PCL.
