Got the new headset back home. Plug in, everything working fine. Hurrah.
Oculus says it needs to install firmware update on headset. Once finished, goes on to sensor check - sensor check fails. Go back to the screen for checking the connections - DP connection not working.
And now I thionk about it, that's what happened with the last one too. So the firmware update is to blame?
That's very strange, if the update was to blame there would be a lot more reports of this happening.
Can you roll back the firmware?
Or, try to use the Public test channel. See if that fixes your problem.
