[2018] Developing for Rift without a headset in 1.24, Oculus Debug Tool not working

Soooo I used to work with my development while I am outside using the method referred by @Ybalrid in this link.

But it seems everything get different after oculus runtime 1.3 or 1.4 or so.

Now I try the same way, toggle the "Debug HMD Type" to "CV1", and it just now work anymore.

I see a windows pop out really quickly and just disappear right away. I think that should be the debug hmd windows that supposed to stay there and display the oculus home without shutting down. (like down below, it is taken one year ago) 


And weird thing is oculus app said that the headset is connected (which is right indication), and graphic card begin to run loudly (which is also right indication, cuz Oculus home panel does take a lot on graphic rendering)

I assume it is running correctly, but why the debug hmd windows disappear? and I cannot run the OculusMirror as well.

So any idea to make it work again?
