Black screen, capacitive buttons on - OnePlus 3T Questions & Answers

Ok, so here is my problem, I was in twitter and suddenly the phone froze, I press the power button for a while and my screen never turned on again, although I get the capacitive buttons on, at first I heard sounds like the lockscreen, I even somehow got to twrp with the screen off cause my pc recognised it in recovery mode.
I've tried to enter the mode for bricked phones but as I cannot see anything I'm unable, also tried pressing the power button for 20 seconds multiple times, dont know what else to do.
Any idea will be greatly appreciated.
Also, some info on the phone: OOS 4.1, phh roooted, magisk.

It should be press and hold power plus volume down, for around 20 seconds to force a reboot.

Yeah tried that mĂșltiple times to no avail, it was like the screen was not turning on.
I solved it by waiting 1 hour and trying again and suddenly it was working fine

This has happened to me a number of times already. It completely sucks. I boot to a black screen, capacitive buttons work, I can hold power button until I get the Power Off / Reboot menu, and from there reboot, but the screen keeps being on on the system. Recovery works fine, or so it would seem, because a few times, wiping system and reinstalling the OS gives me a "No OS installed. Are you sure you want to boot?" and EVERY time, the only solution ("solution") has been wiping data. It might start happening randomly, maybe updating Franco Kernel, maybe applying a substratum theme, maybe, like just now, after doing NOTHING at all. I don't know what to do anymore.
edit. of course, the hard bricking guide, step 2, works, but step 2 deletes your data, and if i remove the erase userdata lines, it doesn't do anything.

[Q] Sprint HTC ONE stuck on white boot screen

Hello,
I've just installed this ROM after wiping Cache/Delvik Cache and system wipe.
Now the phone is stuck on the boot screen and I can not get back into recovery to sort it out.
I held down power & vol+ buttons to get into recovery but nothing happens. The Home & Back buttons flash after 3 seconds then nothing happens.
Any thing else I should do to get into recovery ( TWRP)
My friend whop is a member asked this question on the Developers forum and so far no luck.
we have tried the following:
This is suggested by chogardjr: Plug your phone in to charge. Don't use a USB port for power. After you plug it in try the hard reboot again.
PLEASE HELP
Just for the sake of testing... Have him hold power without holding the volume. It should force reboot, not to the bootloader, so he can get a feel for how the reboot works. It can be finicky during a bootloop cause there are processes trying to run in the background. But it should do it if you hold power long enough.
Edit:
Also find out if the charge light comes on when he plus it in.
Tried and no joy.......

I had a similar problem with a bad kernel flash and could not get the device to shut all the way off - thats why the keys are blinking. I plugged it in to a charger, left it like that for a few seconds, then unplugged, held it under a bright light and waited. After a few more seconds, it shut all the way down and I was able to boot to recovery in the usual way (power+down). You may have to try combinations or maybe not. But, you won't get to recovery until the phone shuts all the way down. High light under in the 'eyes', plugging and unplugging, and holding the power button for up to 30 seconds are all known ways to do this, but as was said before a bootloop has processes trying to run, so the machine can be 'confused' and have difficulty shutting down. Hope you are successful...
Thanks. I actually got it going with one of the answers posted for me, by powering it off under a bright light.
Sounds daft, but it works.

Power button issue

I just discovered yesterday that my power button seem to be not working. Pressing it doesnt lock the screen and long pressing it doesnt bring up the power options. Tried wiping everything and still the issue remains. When I pull my battery and then insert it back the phone boots itself, as if the power button is pressed all the time (even though i can still click it and its not stuck). Ive been using rom toolbox for the power menu but choosing to turn off the phone makes my phone have a screen freeze, all other options work like reboot, fast reboot, reboot recovery etc. Anyone know how to fix this?
Edit: After a couple of days my power button is working again

How did you get it to work? Or did it started working on it's on? Thanks
I've seen that happen on mine, due to a bad USB charge port. Replaced it, problem disappeared.
Any chance your device sometimes thinks it is docked to a docking station?
Inexpensive part to obtain, less than 10 dollars (usd), takes about 15 minutes or less to replace.
In the 2+ years I've had mine, I've gone through 4 of them LOL...I'm hard on charge ports I guess.

It just started working again. When I turned off my phone to place my sim back and it didnt boot up automatically, I knew the power button is working again. Pressed the power button, device booted up and the issue is gone. I dont know if mh device thinks its docked, i dont have a docking station and ive never had problems with my charging port yet.
I've been using my N7000 for 2 years and this thing happened for 3-4 times. The lock button will be like stop working, sometimes it is like being press all the time and the problem will be sorted out by itself. Normally when this happens, the phone will be laggy and will reboot by itself. Is it a common thing for this phone?how do you get your phone fixed Kcube989?

[Q] N6 AT&T: Screen will not turn on

I've had my phone almost a week now. Last night the screen stopped turning on. I can hear notifications telling me the phone is on, just not the screen. I did a google search and saw similar problems on the N4 and N5. I have tried there methods now over 100 times and still no success. I am holding POWER + VOLUME-DOWN for 15-20 seconds then plugging in USB port but this in a number of variations is not working. Is anyone else having this problem and do you know of a fix for this?
Phone is not rooted if that helps.
Make sure you still have battery (plug it into the wall) then hold down volume up+volume down+power until you get into the bootloader.. From there you can flash factory images or try going into recovery (use volume up to scroll to recovery mode) and do a factory reset. Once in recovery you will need to hold down the power button and tap the volume up button once to bring up the menu for factory reset.
tried that, no luck since the screen doesnt turn on. any other ideas?
you got a sod(sleep of death). the only way around this is to press the power button for 20-25 seconds straight, then reboot. or, there a possibility that your screen stopped working.
Have you tried plugging it into the computer and giving it adb commands to boot into BL?
I wonder if this is an issue with Android in general on rare occasions since KitKat. I had this problem too on my LG G2
yeah, i tried all of these methods and gave up. at&t gave me a new one since i was under 14 days. the lady said they had a whole batch of n6 they had to ship back because of problems and that the newest batch "should" be problem free.

HTC One will not stop rebooting

Hi all,
Recently my HTC One would randomly have a pop-up that said something along the lines of "To reboot, press and hold the power button" along with a countdown and then the phone will reboot itself. This can happen any time, sometimes multiple times within a half hour, even when it is charging.
The last time it happened, it rebooted, got to the blank black screen, and rebooted again. I've plugged it in to charge but it would not stop rebooting. I've unplugged it to let it run out of battery so hopefully it would stop rebooting itself and I can try charging it again. Once it ran out of juice, I charged it and it continued rebooting itself. Pressing the power + volume keys only worked twice but the screen wouldn't stay long enough for me to select fast reboot or factory reset before rebooting itself again. Now pressing power + volume keys doesn't cause any effect on the phone.
I've never tempered with any of the software settings on my phone and it has been sent for repair three times last year. Also, my laptop does not recognise the phone when I plug it to my laptop.
Any advice would be much appreciated! Thank you in advance!

Normally you get this message when holding the power button. So this message in addition to the rebooting issues makes me believe you have an hardware problem with your power button, maybe its stuck?

I tried pressing on the power button, it seems to be depressing fine. Is there any way I can affirm this?

I think what you explained at post #1 is enough to conclude your power button or something hardware related to it is the problem. I think you'll have to send your device for repair unfortunately unless you want to open the phone yourself to have a look which is not always good idea.

Power Button problem ?

Hello!
Not later than this morning I realized a problem on my Idol 4. At random moments it restarts. When it is on the screen of starting up it continues to restart in a loop. I came to the conclusion that it is a problem with the power button because when I press the volume buttons to enter download mode or even recovery, it quit the download mode (which is done by pressing power) and select options automatically in recovery (which also done by pressing power). So when it restarts I just press the power button randomly, try to pull it out of the phone and then it stops restarting. But again, minutes later it restarts... The button seems not broken or anything that kind but maybe it's in the inside ?
So just questionning how can I fix this.
Thank you a lot !
I think you can just pop the screen off and buy a replacement the idol three was pretty easy to replace. No special tools just used my nails
