I have found the issue with mine to be the proximity sensor that detects when the device is being worn. I have managed to get it running long enough for me to enable Dev mode and accept the ADB connection from my computer and using the Oculus Dev Hub to forcefully disabling the sensor fixed my issue. I've still put in for a RMA and just waiting for FedEX to come pick it up.
i had the same problem but i fixed it. no clear.. anything on HOW, but basically:
after powering off and back on, charging, and even a factory reset didn't work, i pressed and held one volume and the power buttons until that little green android bot showed up on the headset with a red triangle ! in an open control panel. it wouldn't let me do anything at that point, so i kept pressing and holding buttons until i think the power button turned it off? and when i powered it back on, it was working and i went through the setup again, connected my app, and redownloaded my games. it was plugged in the whole time.
not sure how it would, but i hope this helps someone.
(READ) Don't panic and return like I almost did!! If nothing works, chances are might be the facial sensor inside the headset above the lenses not detecting your face, so when you turn it on it shows the logo, but then quickly goes to black screen as if your face isn't there in front of it. Solution: get a few layers of masking tape and put it over the sensor so it detects presence and the black screen goes away, set up guardian, then play normally. Almost tossed this yearold quest after factory reset didnt work, then my little brother came up with this idea and it worked perfectly, dont want anyone wasting good money lol.
I've had this with two oculus 2 headsets now. With where I live returning is difficult so I have persevered with trying to fix the problem. My second headset has only lasted three weeks! I've tried every solution I could find on google and youtube including factory resets and have seen that oculus support does not provide any answers or admit to any known problems. I do not use the pc link cable though I have ordered one to see if it might allow for a different solution. I had the original oculus quest and didn't have these problems, only the controllers battery consumption was a little annoying. I think the black screen of death is happening to more and more people and would be interested to know how many people are facing the same frustrations.
It's great tech and I love it when it's working!!!!
i have actually found that letting it register light from a lamp or something by pointing the face part toward it and then putting it on your face fixes it. if it's in the dark frequently (in a case maybe), it might not recognize that it's on your face when you put it on. it needs to re-recognize the difference between light and against your face. do not use direct sunlight or bright lights, but my lamp on a mid setting works fine
