Hello helpful people.
Greetings.
I own a Oneplus 8T device Indian variant, which I have been using since last 14 months. It was working fine so far, however today I was downloading a movie from UC browser and as I was out of my home I kept my phone in charge with different charger. Later after about 20 minutes I checked my phone when suddenly it showed 'Qualcomm crash dump mode - dead' something like this. I worried little and googled and found that pressing 3 buttons together can lead it to something in different mode or safe mode something like that. I instantly tried and it might switched off my phone or let it die, no buttons are working as I tried different combinations. I watched numerous videos available and surfed too many blogs, sites, posts regarding this issue. But in my case, I can't get into fastboot mode or edl mode. I desperately need your help, please.
good morning friend, the solution is easy, the problem is that it will erase all your data, holding down the volume and lock buttons works, just keep it that way until I turned off, I had a similar experience wanting to exit ColorOs I recommend that you have the MSM tool ready to restore your device, I remind you if you must keep the buttons pressed for one hour, do it.

thanks for your attention. i appreciate it. but pressing 2 buttons for an hour doesn't feel easy task. i don't think that i can press them for more than 5-10 minutes at a time. anyways thanks.

Try just Power+Vol Up.
That's worked for me and only takes a few seconds.
Then, when it starts to reboot hold Vol Up+Vol Down and you should end up in Bootloader.
tried power + volume up key for 2 minutes. no response yet.

Have you used the MSM tool before? If so, try holding Vol Up+Vol Down and connecting to PC with MSM running.

The only other thing I can think of is to let the phone shut down as the battery runs low. Then charge it up sufficiently to boot into bootloader.

today I have shown the phone to a local mender, when he said that the phone is taking charge and it was at 96% today morning. charging is not an issue right now.
i think this issue is beyond my hand and i must send my phone to customer service center. anyways thank you beautiful and helpful people around here for your valuable suggestions and advice.

I wanted to install cynagoenmod so
1. I unlocked bootloader using HTC dev
2. I flashed cwm recovery
3. I flashed boot.img extracted from the cynagoenmod release
it was stuck in the boot-up at the HTC logo with the disclaimer text "this build is meant for developers....."
I had to run an errand so I left it as is.
when I got back it wouldn't turn on
wont blink the soft-keys after holding the power button for 10 seconds
wont boot into bootloader when holding both the vol- and power button
when connected to the charger the LED stays on orange for about a minute and turns off
only response it does a flash of white (like this like when u close the TV effect ) after holding the power button for 20 seconds
any advice would be welcome
Just keep holding the power button and also the volume down button for 20-30 seconds. It should pop into HBOOT.
If you see the screen flashing white that should mean it isn't hard bricked.

That's strange. Does your PC detect it when you connect via USB?
Plug it in and if nothing happens, press/hold all three buttons in different combinations and sequences and hopefully something should happen.

We'll need a bit more information. What exactly happened (read: what did you do) before it stopped responding?
General approach
a) press power button for 30 seconds straight
b) plug it into wall charger and wait ~30min
c) unplug and press power button for 30 seconds again
d) press vol-down, keep it pressed, and press power. It should enter fastboot mode
If you managed (d) successfully your phone can be fixed.

I am assuming you are coming from Samsung. It does not seem as if the OPO has anything resembling an EFS folder so no need to back it up.
At least that seemed to be the general consensus when I asked a similar question a while back on their forum.

Hello made by the person wanted to update to version XPNPH25R and the phone has not been planted and on again.
He try your trick but nothing works and I think it well bricker
opo does have an efs partition.
also stock cm11s has a quick boot feature. let the phone run empty. then charge it for a cpl of hours. then boot it up and try to either enter fastboot or recovery and check if those partitions still are bootable. if not it seems the partitiontables are busted. if you can not get to either its rma time
cheers

Ok. I am writing here since it was suggested. I am having a major issue and unsure how to fix it. The following is the issue and steps taken thus far with no resolve. Hopefully someone else has an answer to assist me. I really need this phone to work as it is my lifeline.
Star is I have all updated firmware, rom, and even updated xtended settings. I have today also installed the viper sound for the first time. I will say I have settings changed throughout with all the variations. Xtended settings, nusense toolbox, vipersound, normal settings, and Xposed framework.
What is happening is the phone needed a reboot. It shows the splashscreen and then shuts off. It will not fully boot. I have tried to hold the power vol/up buttons together and quickly vol/down. But that does not work. Now I have also tried adb and attempted to find the device but with no power seemingly it is not able to work.
Anyone have suggestions I might try? Please advise.I have even attempted adb but the pc does not see the device since it never gets fully turned on. It is a splashscreen and then dead. Really wish there was a way to get it to just turn on for access somehow. Anyone have a suggestion?
Have you tried holding the power button and up button till you get into fastboot?

I have actually held the button where it will only show the splashscreen and then show a bit of the TWRP recovery screen. However I cannot pick anything from the menu before it goes to the battery icon showing it is simply charging. I really have no clue what is needed to be done now. I am surprised it has let me get that far without just turning off again. But this was done by holding the volume button up and down and power button all at the same time.
Do you have any other suggestions since it is not being seen by adb on the pc?

It should let you get into the bootloader if it gets you to the splashscreen @Tigerstown any ideas?

Unplug your phone. Then hold power and volume up for 30 seconds. Plugged in you are hitting the twrp bug.
Edit... After unplugging wait 20 seconds before attempting to boot it.

Thanks dottat i didnt even think of telling him unplug it
So before, my power button gave me issues where it required substantial force to be used in order to get any response. Now all of a sudden, the fingerprint sensor went out as well as the power button itself. When attempting to do a hard reset to correct the problem, the phone won't turn on anymore. So it would seem that the power button no longer works and now I cannot turn on my phone . I've attempted to go into download mode or even the bootloader with little to no luck at all.
Does anyone have an alternative way to power on the phone so I can attempt to backup my data?

This took a lot of trial and error with various button combinations, but I think I found a solution that works.
You must use the wall charger and cord. That's what I used.
1. Press and hold the volume up and down button at the same time.
2. Plug in the wall charger to the charging port.
3. You will see the lg logo on your phone.
4 Right when you see the lg logo unplug the charger from the phone.
5. Continue holding the volume up and down button.
6. LG logo will go away and then come back and your phone should boot.
5. Release the volume up and down button when it starts to boot.
Note: If you don't pull the power cord right when you see the lg logo, it will go into charging mode.
I was able to successfully boot my phone from a powered off state this way 3 times with no problem.
Once you get it booted, you could download an app from the play store to remap a volume button to be a power button as a temporary solution.

I hope this helps.

Hi, I have a One Plus 8T that won't turn on, won't charge, won't get into recovery mode, the screen remains black, won't vibrate on changing ringing mode either and gets recognized as QUSB_BULK_CID:xxxx_SN:xxxxxxxx when connected to the laptop. Phone was in my hand and in a perfectly good condition when it happened. I tried all the physical keys and their combinations many times. Is there any solution to this?

You're in EDL mode. Hold power button and volume up button until it reboots. Then see where you are. However, you may need to use this tool to flash back to stock - https://forum.xda-developers.com/t/...l-to-restore-your-device-to-oxygenos.4180837/

one thing i want to add here is when phone is conected to a laptop and i press Vol Up + Power key, i hear a beep on laptop (may be it does the reboot) but screen remains black. I dont think the issue is with the disoplay.
Then you will need to use the msm tool. Your phone seems to boot into EDL mode just fine. Follow the instructions in that link.
