[Urgent] Help please, phone wont start - OnePlus 6T Questions & Answers

Hi,
I slept last night with ~40% in my OP6T. When I woke up, the phone wont start anymore. I am rooted with the latest Magisk, and latest stock rom.
When I press the power power button, it doesnt even show me the screen where I have the bootloader warning. I've tried pressing the power key alone for 15 seconds, power + up volume for 15 seconds , power key + down volume for 15 seconds, power key + both volume keys for 15 seconds but nothing happens.
I just cannot get my screen to start:crying::crying::crying:
I have also tried connecting my phone to the laptop, I get a "safely remove OP6T" notification in the task bar, but my phone inst identified in the storage..
If anyone could help me, that would be greatly appreciated.
Thanks a lot

It's probably out of charge, happened to me and I just left it on charge for 15 minutes and then held the power button and it worked.

Hold pwr and up button for a couple of seconds.

So after 1000s of attempts, its started on its own (on the 1001th ) attempt when I held the vol up and pwr button. It wasnt a case of battery drain as I had only connected it to the system for 10 mins and the battery when it started was 53%.
Is there a way to find out how it tuned off ? some crash logs or something ?
Can an admin please close this thread ?

Yeah it seems like there's an issue with the phone loading up after it's went dead..and I've had that issue a few times where I had to play with it for an hour in order for it to finally load...I even knew it was dead and plugged it up to a charger and it would stay on the bootloader screen and I left it on the charger for an hour or so..and then held the <pwr><vol+> to shut it off and when I did all that I then powered it on and took the charging cable out and it still said it was low battery..so while on the unlocked bootloader screen it wasn't charging(weird)..so after fooling with it summore I finally got it to charge just random didn't do anything I hadn't previously done and all was good. But it seems like this only happens after it dies and I don't Kno if the unlocked bootloader is the issue or what but it's aggravating to have to fool with it for that long.

I think there is something wrong with your ROM.. Are you rooted? If I were you, I'd wipe the phone completely and install a new Rom, redoing the setup from scratch..

I have wiped and rooted with magisk and twrp recovery installed.. and I have zero issues in the current setup..now only when it has died did this seem to happen..oh I have wiped 3x because of bootloop and soft brick previously..so I don't think that is the solution (wipe and clean install)..just weird

I haven't tried this, but from what I've read, using the MSM tool is the only sure way to completely factory reset your phone.. Using anything else could leave remnants in the ROM causing problems..

For some reason my fastboot drivers are not working anymore, the MSM tool is not a option for me.

Battery Drained Completely In Recovery

Okay, so my power button broke, and I've been using widgets and shortcuts on my phone to lock it and restart etc and my pc and ADB to turn it on once its off. So I decided to flash Cyanogenmod 12 on my phone, i logged into recovery, wiped my phone, and then got stuck in the recovery because the touch screen wasn't working wHere the navigation buttons in TWRP are. The power button is broken, so I couldn't turn it on. I didn't have the tools to perform a battery pull either. -_- So I decided to wait till my phone's battery was completely drained on TWRP, took almost 5-6 hours. And now my phone won't even charge. Did I brick it or something?
BUMP.. please help people :/
Connect the charger and i am sure it will charge the battery. Then after an hour or so unplug the charger and after 15 seconds connect your charger again but remember to use the key combination for recovery (like if volume up and power button gets you in recovery then just use volume up button). You dont need power key as charger will do this for you. Now you will be in recovery and from there you can do reboot or flash a custom rom.

Is it a necessity that I wait 15 seconds before plugging it in again?

Phone not turning on and led flashing rapidly

I just flashed MOAR rom on my phone a few days ago and everything was working perfectly then while at work I pulled my phone out of my pocket and noticed my case had slipped off and was holding the power button down. After fixing the case I tried to unlock my phone and nothing came up on my screen. I held down the power button and the only thing that happened was my LED indicator is flashing green rapidly and at different brightness. Then I pulled the battery and left it out of my phone for 2 hours and still the only thing that is happening is the LED. When I plug it into my computer without me hitting the button the LED is flashing. It wont boot into recovery and I don't want to send it in and them find a custom rom on it so any help would be greatly appreciated.

I am assuming it won't go into download mode either? Try holding the power button in for at least 30-40 seconds.

No, I've tried holding just the power button for a minute or trying to go into either download or recovery mode and got nothing.

Try the same thing with the charger plugged in.
"Try holding down the power button for 1 minute with the charger connected. If this doesn't present the screen, try holding the power button AND both volume buttons at the same time. This should bring up a menu. There should be an option for reboot or force reboot"

Thanks for trying to help, I've tried holding both volume and power button for a minute and nothing. After having it plugged in for a few minutes my battery started to get warm.

Just something I found while looking for answers. At least your battery is getting warm. That is better than the alternative.

Are you using the original data cable? Try a different USB port maybe?

Please Help! LG G2 Won't Boot Up

I had rooted my dad's lg g2( D802) and installed twrp using an app named autorec as it was recommended by many people in the internet and had very high ratings and downloads in the play store. Everything was fine for a few weeks till I noticed that the app had an update. So I flashed twrp again from the app hoping it was a newer version and it said it completed the operation successfully. Then I just used the phone for sometime and after that I switched off the phone to enter the recovery. After it switched off, I pressed the button combination for entering the recovery but nothing came up. Then I attempted to just boot the phone and kept pressing the power button but nothing came up. I even kept pressing the button for upto a minute to hard reboot it in case it was just a case of hanging but nothing came up.After that, I plugged it in for charging and attempted to boot again. After I kept pressing the power button for about 30 seconds while charging, the led blinked red 8 times, paused and repeated itself as long as I kept holding the power button.
The problem is that it even the screen doesn't turn on.
I searched for this issue and saw that many others were facing this issue. I tried the following solutions given by them which did not work:
1) Holding the power button for a long time
2) Keeping it for charging until it's full but nothing comes up and the phone got heated up very much untill I stopped it a few hours later.
3) Removing the back cover and detaching the battery power cable from the phone after after waiting for sometime, reattaching it.
My dad showed it to the lg repair centre but they told him they need to replace the whole board which is very expensive, especially considering that it is a 2+ year old phone. My dad is very angry at me and probably won't let me touch his phones ever again if I don't fix this. Please help me.
Thanks in Advance
Edit: the charge was at 45% when I switched it off. Don't think it is because of low battery
With the phone pluggged into your computer, does the computer recognize the phone? And if yes, what does Device Manager report it as being?

more info... what variant? phone does not boot.. can you press vol up then plug phone .. does download mode works... stay calmed this can be fixed..:fingers-crossed:
I haven't tried plugging it to the computer. The way to enter download mode is holding the volume up button right? Thank you for the suggestion. I'm away for a few days but I'll tell my dad to do so. I'll post what happens then. Variant is D802
OK I told him to do that. When he pressed the volume up button and then plugged it to his computer, 13 new partitions showed up in windows, and it is telling him that he needs to format the positions to use it. But nothing is coming up on the phone
Do NOT let Windows format the partitions(!)
Use the SRKTool instead to unbrick from qhsusb_bulk mode:
http://forum.xda-developers.com/lg-g2/development/tools-srk-tool-useful-toos-lg-root-twrp-t3079076
Afterwards use LG Flash Tool 2014 to flash the KDZ for your variant:
http://forum.xda-developers.com/showthread.php?t=2432476
It's better to let the battery charge to full first. Shut down the phone by holding PWR button for 10 seconds, then plug charger. It should work even in bulk mode.
Did you try these simple things...
shutdown phone keeping powerbutton down.
Start pressing power button & vol down....when you see LG logo for couple seconds. Release fingers and press vol UP and vol DOWN, same time. No power button.

But the problem is, even the screen doesn't turn on while on download mode. I'll surely try out the unbrick tool but will it work since normally, the download mode screen comes up. That thing is 760mb. I think it'll take some time for it to finish. (Ultra slow internet connection )

The lg logo doesn't come up when I do that. If fact, even the screen does not turn on

Phone freezes and reset is impossible

The phone is on original 7.0 rom. Since 2 or 3 weeks the device gets frozen unconditionaly. I tried holding power and volume down button for more than 30 secs to restart but this and other combinations didn't work. Only waiting for a battery drain off make the phone restartable.

Mine is doing the same thing. It also reboots randomly. I am beginning to suspect that it is a hardware problem.

power & volume down when device is on is screenshot
power and volume down when device is off wont do anything - you need to press home as well. But that combination is for download mode not recovery, which is volume up, home and power.

That may not work either - I have had black screen several time (usually on S8 Ports), when the only way to restart it is easy but annoying.
Just plug it into a power source. As soon as you see anything on the screen, go to download mode, but use sound down button as soon as download comes up and it should reboot.
Have had to do it around 12 times in the last few months.

I just experience the same issue and have tried all the button combinations. Are you simply just leaving the phone alone for the battery drain off? THat is the only thing I have not tried as I don't know when the battery is dead.

OnePlus 6T Won't Turn On

I just encountered a very strange and worrisome issue today. I successfully rooted my OnePlus 6T and installed Magisk with TWRP following these instructions.
After reinstalling my apps, installing the AdAway apk, and rebooting (using the system dialog) after I was prompted to, my phone refuses to start.
The screen is all black with no signs of any activity. I tried holding the power button for 10+ seconds in various combinations with the volume buttons. None of them worked. The phone is definitely not battery dead because I clearly remember the phone was plugged into my computer and at 83% at the time it shut off. I hardly believe I bricked my phone because the rooting process was 100% successful.
Any help would be greatly appreciated.
Plugging in your phone have any signs of activity? Might be in qcom mode. Worked for me to hold power and volume Up for like 30 seconds.
I've had this issue a few times, I was always able to get it to turn on by holding vol up + power for an extended period of time.
