Black Screen / Nothing rendered - Unity 5.1.2 f1 & Cardboard v0.5.1

Update from: http://forum.unity3d.com/threads/unity-5-1-2-f1-cardboard-v0-5-1-breaks-eventmanager.343728/

I just created a new, clean Unity project with Unity 5.1.2 f1 & Cardboard v0.5.1.
DeviceID in plugins → Android → assets folder
VR disabled in Unity
VR Mode enabled in Cardboard main prefab

1 worldspace canvas with 1 button.

I get a black screen when pushing to Android running 4.4

If I turn off “VR Mode Enabled” on the Cardboard Main prefab I get the VR scene but nothing is rendered.

Does anybody have any idea what could be causing this?
p.s. Before the updates everything worked perfectly.

Thanks
