Just got the Vive Focus, it and the controller were working just fine. The controller did it's firm ware update. I played around a while, then I built the unity sample and adb installed it to the HMD. I adb installed tools\wvr_mobileHMD.apk and services\oemservice-release.apk as the getting started guide states, and then I restarted the head set. From that point on, the light on the controller does a slow white blink until it times out. The HMD still works fine, but with no controller all I can do is shutdown or restart.. Any ideas? I used adb uninstall to remove those two apks, and then rebooted, but still the same problem, controller light just blinks for a while then turns off, no connection. Tried every combination of HMD volume buttons and controller buttons held down, no luck, they just won’t pair.
