I have now confirmed with other users that the small LED should be solid red when switched on, solid green when the connection to the PC is established and solid purple when in use with a VR application.
I have tried finding resources as to what LED codes mean for the 5K+ but am making no progress.
So as it’s stands the power LED is flashing green and the HMD is not recognized. What should I do? Is this a hardware issue? If so, is there an RMA process in place?
