6T Will not turn on - OnePlus 6T Questions & Answers

I was updating the apps on my phone and did a reboot. The device powered off and now I can't get it to turn on. I tried holding down the power button for 20 seconds but nothing. I have it plugged into a USB C cable now. I tried holding the power button and each of the volume buttons and nothing. Does anyone else have any suggestions.

yeah call oneplus and get a new replacement coming

Hold power + volume up. I had the same issue yesterday.

Thank you so much! I tried it before but I guess I was not holding it long enough.

Why does it happen.

Try holding Power+Both volume buttons for 10 seconds, then try to boot.

Volume Down and Power button don't seem to work anymore

Something just happened to my phone where the touchscreen actions went a little crazy for a second or two and then the Volume Down and Power button don't seem to work anymore.
The Volume Up button still works though...
Has this happened to anyone else? Is there a way to turn off or reboot the device without using the power button?
Volume down, power and home button. All 3.

Thank you!
Actually, I found in this case holding down Volume Down and Power caused the phone to reboot. I wonder if something got stuck...
It happened to me as well and I found some article which said to hold power +down button for some time and it will reboot

My phone will not turn on at all.

My phone was working fine. I was running completely stock, but rooted with absolutely no changes to anything. I went to bed and woke up and I saw the green light indicating a full charge. However, nothing happens when I press the power button. It does not respond to anything other than a vibration when I press volume up and down, plus the power button. It doesn't even start to boot or make any sound. It does not respond to the charging cord either. Nor will it respond to ADB. Any ideas other than sending it to HTC?
Try holding power + volume down. The lights at the bottom should start flashing, I think mine flash 14 times and then I get a reboot. Maybe volume up instead but I think it's volume down.
Possibly your usb-c cord is bad. Try to charge it with another cord for a while and try what silverzero said. Hold volume down and power together for a min and see if you can get into recovery.

I was having that problem too and remedied it by just pressing and holding random buttons down for random periods of time lol. Sorry it's not more precise. Eventually I had the power button held down with the volume up and it ended up turning on. Was down for a good like 2-5 min though with absolutely no signs of turning on.
Was only getting that problem after I selected oem unlock from dev options menu.
When it did turn back on, I powered down completely and held vol down with power to go into recovery and selected fastboot from that menu.

Yeah, thats what happened to me as well holding both Vol up and down with power. Now I either do vol up with power or vol down with power... never both haha. But I don't think vol up with power does anything.

for whoever has this issue and needs to see this, my steps to cut it back on (finally):
1. let it sit on the charger for like 5-10 minutes
2. unplug let sit again for a few minutes
3. pressed power and both volume buttons till i felt a buzz and it cut right on.

[Help] one plus 6t not vibrating or turning on after being plugged up

So I have a rooted oneplus 6t that was doing quite well for a little while now but for some reason today it died when it was hooked up to a charger. When I unplugged it and plugged it back in it did its usual vibration to signify it was connected but then it showed a qualcomm crash error (died too quickly to see it fully but it was small so I at least saw some of what it said) now when I try to let it charge it doesnt vibrate and doesnt even turn on when I left it on charge for a good hour now and when i hold vol up +power,vol down + power,both vol +power,or just power for their respective seconds to get the phone to respond. Tried looking for a answer online but none are similar to what i am having atm. Also my computer wont even see it either while it's like this. I've tried other cords as well to see if it was a cord issue and wasnt it's been sitting on the charger since 10:55 am est. Help?
It usually just takes some persistence. Usually the power + volume up will force it off, and then power it back on does the trick, sometimes it seems like it's all three buttons (which shouldn't do anything?) . I've had a couple times I've been just about to give up when it finally boots back up to fastboot.
Volume Up + Power while turning on will boot to fastboot.
Volume Down + Power while turn on will boot to recovery.
Holding Volume Up + Power should force the phone to turn off.
Volume Up + Volume Down should put your phone in Download mode for the MSM Tool.
Make sure you hold the buttons much long than you think you should have too.
