Is my stock phone bricked?

It's a stock phone, unrooted bootloader locked. The phone was updated to the latest firmware a few days ago and was working well since.
Today I left the phone on the desk for a while. When I came back, the phone had rebooted and was in the fastboot mode screen.
I tried to restart but it just loops back to same screen. Does not even go into recovery!!
What snapped it, cant understand!
Is it bricked? How do I revive the phone now?
Please help!
Thanks

Could be some CRC glitch in the main memory which prevents your phone from boot.
Being in FB mode try to flash some stock ROM (download the latest stock or Beta 9). Don't try to go to Recovery, flash from FB with fastboot utility.

Do I also need to flash stock recovery from fastboot?
Thanks again.

No, recovery is part of the ROM, so not needed.

If it's a completely stock device, why not contact OnePlus and get a replacement?

Are you guys suggesting ADB sideload command? My USB debugging seems to be off, returns empty on "adb devices"
I am unaware of fastboot command to flash the stock rom, googled it but could not figure out the right command.
Thanks

That's right.
If am not able to fix it myself with members help, I'll have to go through customer support drill.

(a) there is no such thing as "bricked" when it comes to any OP Qualcomm devices
(b) as with ANY OP Qualcomm, OnePlus can reflash remotely directly to the Qualcomm or you can do the same thing yourself. Just follow the simple instructions.

Thanks for the assistance.
I tried the unbrick tool, but device manager (Windows 7 64bit) shows the device as Oneplus Android Bootloader Interface (under Samsung Android Phone )
Therefore, MSMDownloadTool does not show any device in the list.

Thanks

Fastboot not working

Hi everyone,
after a whole day spent try to fix my oneplus 6, now the roblem is that the fastboot is not working anymore. it gets stuck at the starting point with the oneplus logo and the writing Fastboot Mode.
Just to explain better, i rooted my phone but, trying to fix an audio problem, i did something wrong (probavly wiping all datas with twrp) and the phone got stuck at the Fastboot mode (opposite problem that i have now). After i fixed this (flashing manually every partitions) the phone is working again, but i realised that, by mistake, i used the oxygen 9.0.11 for oneplus 6T. So i tried to go to the Fastboot Mode but it gets stuck at that point. I also see that the phone is not rooted anymore.
I installed again Adb and fastboot but it doesn't fix the problem.
Just to give other random informations, the boot loader is still unlocked and i can't lock it.
As you can see i'm totally not an expert. I just wanted to root my oneplus 6 to increase the volume of the headphones.
Anyone that can help me?
Thanks

Try: https://forum.xda-developers.com/oneplus-6/how-to/guide-mega-unbrick-guide-hard-bricked-t3796051
The idea is to boot it in download mode. You'll need the Qualcomm drivers, msm download tool, and oos full rom. Run the tool as administrator.

Fastboot require Android SDK(Software Development Kit) and different USB drivers for windows computer may be that's the reason why your Fastboot is not working.

[HELP] Bricked Oneplus 6 - Qualcomm CrashDump - already tried everything

Hi everyone!
Well guys, sorry to bring this subject on thread again (because this forum has a lot of guides to solve this problem).
But I'm without hope with my phone at this moment.
Let me tell you guys my sad story...
I have an Oneplus 6 since december 2018, and never, NEVER, tried to use any modification on my phone.
I am from Brazil (so sorry for my bad english =] ), and here we CANNOT use Oneplus Support services (I've tried but only received the response "sorry I cannot help you on your country"), so because of this, I've decided to never apply any modification to avoid problems.
This week after a simple reboot my OP6 started with "Qualcomm CrashDump" error and my despair begins.
I'm not able to enter on Fastboot Mode. When I try, the systems attempt to boot (the fastboot mode logo appears) and fall down into crash again.
I'm not able to enter on Recovery Mode either. This method shows nothing, only black screen and after some time the crash screen comes again.
I do not have Bootloader unlocked too.
Any suggestion to use TWRP via fastboot.exe or ADB are useless, because I cant make the connection. At least I think that is impossible because the 'adb devices' command does not find the device.
I followed a lot of guides from XDA to solve my problem, including the Mega Unbrick Thread.
I already downloaded at least 8 different versions of msmdownloadtool in consecutive attempts of unbrick my phone. Nothing really helps.
The most weird situation is that msmDownlodTool can finish the proccess with success. The driver installation is working... everything seens OK using the tool but my phone does not revive
Someone have a suggestion for me?
Any suggestion, tool or alternative method is welcome in my actual situation.
Sorry if I posted at wrong local, just tell me and I can fix if necessary.
Thanks in advance to all of you guys.

Did you try msm download tool? If not, nead that thread and good luck

Hi!
Thanks for your reply, but I think you do not read my entire post
As I said, i've already tried at least 8 different versions of msmDownloadTool.
If you have any other suggestion, I'll appreciate.

so you can't boot into fastbootmode anymore?
Had the same problem once before and solved it by flashing the correct twrp by fastboot

Yes, I am unable to enter into Fastboot Mode.
When I try, the logo saying "fastboot" appears, but after 4 seconds, the systems stucks on CrashDump error screen again.
That way my PC cannot find my phone with ADB or FASTBOOT commands.
The only tool that works is msmDownloadTool, but even with a success run with that tool, my system does not start and stills under CrashDump error.
I was thinking if exists some version of msmDownloadTool that justs restore the fastboot and unlock bootloader with brute force.
Thats my last hope

Source is a videotutorial. google oneplus 6 hardbrick and click the video of Max Lee
(it worked for me)
the download takes an awful lot of time
first get your phone into qualcomm download mode by holding down volume up + power button and plug your device in your PC.
(first unzip the hardbrick zip folder) then the oneplus 6 folder and than the .exe file and click 'start' if it detects your phone.
That is flashing every chip and Hydrogen OS 5.whatever.3 but that is not important. Your phone should boot and than you can install Oxygen OS with android 10(thats the other zip folder) using the local upgrade feature.
(make sure to enable google play services after upgrade from hydrogen OS)
Hope it will work for you too if you haven't tried it already.

Question Super-Hard Bricked OnePlus 9

I have an extremely big problem, maybe someone could help me here?
So today I tried to flash diffrent OOS version on my OnePlus 9, I did it with fastboot, after the command "fastboot reboot fastboot" the screen on the phone went blank and there was a sound on the computer as if the phone was still connecting and disconnecting. Now, the phone does not respond to the buttons, the charger, I cannot enter the fastboot, only the EDL mode works, but I cannot use the MSM because it does not detect the phone, I get the "sahara communication failed" notification all the time, previously the same MSM version was working.
Probably the most important thing is that it turned out that the OOS I tried to flash was actually ColorOS, I didn't pay attention to it, I don't know how it happened.
I feel like an idiot, I'm afraid that I will not save this phone myself and that the repair service will also not accept it under warranty, any suggestions?

MSM cannot recognize your phone aka. Sahara Connection error? Check this.
Hi! Today i successfully bricked my OP9 to the point where the global MSM tool couldn't recognize it anymore. I tried everything, from different MSM tools to this thread. Nothing. Then, Deus ex Machina, @flameteam recommended me to try...

Brother what is your phone model is it Chinese (Le2110)? or another model ?

bro i have the same issues , did u found any solution & can you help me plz

See if these steps work for you: (last post)
Display becomes unresponsive after OOS 12 update
I upgraded my OnePlus 9 LE2115 from OOS 11 to OOS 12, and every time the phone reboots after completing the update, the touch screen is completely unresponsive, so it stays stuck at the lock screen forever. I upgraded from OOS 11.2.10.10 to OOS...

Hey, i have hardbricked my OnePlus 9 and now i have the connect and disconnect-problem in the EDL-Mode. My Model is a Lahaina and i hope it is the same like a Lemonade or a OnePlus 9. I was on the latest Android 12 for the OP 9 before it gets bricked. How i bricked my phone: First i have unlocked the Bootloader and after that i was trying to boot into TWRP. The bootscreen from TWRP comes and the screen gets black and then into boot dump mode. okay, then i installed this: https://forum.xda-developers.com/t/fastboot-rom-pc-required-op9-stock-oos-11-2-2-2aa.4275727/unread and the message <awaiting any device> shows up and i disconnected my phone. After that my phone just shows black and on the pc it just shows up the "QDLoader" (yes, the driver is installed) . How i could bring my phone back to life and fix the partitionproblem/connect & disconnect problem. The MSM just shows "Status of Connection: N/A" and "Waiting for device". I am using an Laptop with Windows 10 on it and an intel chipset.
I think i have killed the partitioning of the oneplus by downgrading from A 12 to A 11. Thanks for your help. By the way: I have downloaded the MSM with Indian OS and I have still the same problem.

I´ve got exactly the same situation and problem as DerBaLu841... Anything to do for now or is the OP9 finally hard bricked now..?

msm tool unroot- stuck on waiting for device

I am trying to use the msm tool to unroot my OnePlus 8t tmobile variant. Using the MSM tool I have run into a few different problems.
1. Drivers. When my phone is in edl mode plugged in to my computer, device manager recognizes it as usb_bulk. I tried using the provided .cab file to update windows Qualcomm drivers but windows could not ever find the files when updating. I found on another forum a automatic installer.
2. Although it now says Qualcomm 9008 windows says that driver digital signature is not recognized or corrupted. However the MSM tool does finally show COM 5 and when I plug in my device is stuck at waiting for device.
I'm pretty stuck right now and any information to help me out would be appreciated.

You need to disable driver signature verification in windows to successfully install drivers.
