guys, its not hard to achieve vr mode, if you have a decent phone. You need to connect phone with wifi or via usb tethering, while opening a VR app, And PC, a same software that does the handshake, then open SteamVR, then your game.
You can buy a vrbox headset and play with it, just few dollars, just think of it like a monitor. Play with RiftCat (cracked,thats what works for me. you can simulate the controller with keyboard and mouse. number 1-4, then scroll). I dont know what works for you, but if you need to try. You can do Riftcat first. If fails, Trinus (trial),ALVR/PhoneVR (free), IruinVR (free), Ivry Driver from Steam (free). Only if all fails, then only try Ivry, cause it fucked up my SteamVR big time, i had to reinstall and restart, a lot troubleshooting.
