So i did something extremely stupid. I flashed an android 9 STOCK ROM while i was in android 10 to fix a magisk and WIFI issue i was having. As a result i cant get into fastboot now and i can only turn the phone on by holding power + volume up button. But doing so only shows the logo for some time which then freezes and the screen goes black. I think the phone has been hard bricked and my only option maybe the unbrick tool. But i can't understand how to use it. I have followed some threads but some of the things aren't adding up. For example in device manager my phone is being detected as Qualcomm HS-USB Diagnostic 900E(COM4) whereas it's supposed to be Qualcomm HS-USB Diagnostic 9008. And also pressing pressing ENUM in the unbrick tool does not detect my device. Any help would be appreciated.
UPDATE : Holding down both volume buttons and power button got me into fastboot mode but the normal way didn't. And from there I discovered I still had stock recovery. I just reset data and everything booted back up properly.

Got my one plus 7 phone stuck into Qualcomm Crashdump mode trying to root using twrp.Everything went fine from unlocking bootloader only until a bad twrp flash resulting in brick only can access fastboot mode and on turning on it shows:

First of all thanks for the reply.U just gave me hope. Did just everything mentioned there in the post but my msm tool is stuck on param preload plz help me over here.
Try to power off the phone by pressing power button and volume up at the same time and keep em pressed for a while until screen turns off (black)
then press both volume buttons at the same time and connect it with your pc.
How do I get to know that I'm in edl mode?

I was having warranty remaining of the device i claimed it and they flashed the software and told me that if it ever happens again no worries because we offer flashing software in phone free of cost according to company's policy
I hard bricked my phone while attempting to convert my device to global. I have never seen a device this dead though, it won't attempt to boot, it gives no vibration when chargers are plugged in, holding the power and volume keys for extended times does absolutely nothing, the device acts like it is absolutely fried.
I tried leaving it on the charger for about an hour and still, there is no sign of life. This was a new (to me) refurbished device that I just got a few weeks ago. Is there anything I can do or try?
You should have all this in place prior to doing anything to device. Unsure if you can even boot edl mode for msm tool now. Probably so !! https://onepluscommunityserver.com/list/Unbrick_Tools/
Find your variant and Google how to use msm tool. Gl bud

And power button and vol + & vol - all 3 together plugged into pc will get you to edl mode. Which is how msm tool connects to device

For some reason I could never get into EDL mode after brick to Qualcomm error. I used the key command you mentioned after plugging in and nothing happened. I even held it for over a minute. Also the tool on OP site didn't work either. I had to send my device for repair under warranty with OnePlus and lost my unlocked bootloader and device was locked and OEM option greyed out again. After OTA A12 update the other day I could OEM unlock. Waiting for unlock code again

Turn your phone off, 30 secs or so, then hold +- volume buttons only, then connect usb lead keep hold until the Qualcomm driver is visible inside device manager ,
Here's driver msm tool from op direct , driver is setup exe ,worked for on total brick m8, and downgrade from android 12 with it too

When I used the Fastboot Enhance tool to flash the payload.bin file, after the flash process finished I try to reboot but unfortunately it was dead.
No Fastboot, no EDL, no recovery, 3 buttons not working, power with up/down not working, when i connect to PC no sound that the pc recognize the phone "OP 8T", when I plug it into charger no info showing, Just black screen.
So it's working now, I'll explain everything here so it might help.
My device is OnePlus 8T DDR5 version
first, I understand what happened to me, I think the tool didn't recognize ram type automatically so it was flash DDR4 on a DDR5 device, so it made a hard brick
at this point, the idea is to connect 2 test points, and you can force your phone to enter to EDL mode, and we can do it in two ways:
1. Rootk1t giude, thax bro Rootk1t
- Removing the back panel by heating it.
- Unplugging battery
- Then use the EDL points on the motherboard to force the device to boot EDL.
- The device immediately will be recognised with just one tap on "enum" now.
- Plugging the battery again and attaching the back panel and rebooting
2. By using deep EDL cable, but not any edl cable, it must be a moded cable so it can be worked with the new security ...... this link will explain
Hydra Tool Gift Xiaomi, Huawei, Redmi Qualcomm EDL Mode New V2 Cable!! - GSM-Forum
Hydra Tool Gift Xiaomi, Huawei, Redmi Qualcomm EDL Mode New V2 Cable!! Hydra Tool New Type-C EDL cable Schematic With this cable you can reboot your
forum.gsmhosting.com
- So i use Hydra EDL Cble V2 , you can buy it from aliexpress
- Be ready and open your MSM tool
- Press the cable button before connecting
- Connect the cable to your phone when you still pressing the button
- Then connect the USB to your PC
- It will automatically put your phone in EDL mode
- Now your phone will show in the MSM tool screen so you can revive it.
Thanks to everyone who tried to help.
Special thanks to Rootk1t , semdoc

Seem like you flashed the wrong xml for the ram type. There is one for ddr4 and ddr5. If EDL is not working I'm afraid according to several post it's an unrecoverable brick...sorry mate!!!
However keep searching for a solution, you never know maybe a new method of recovery from this disaster may exist. I'll keep searching and if I find anything I'll post it here!
Also have you tried the 3 buttons connected from charger and disconnected? Usually for some reason my phone won't respond with the 3 buttons when connected to usb sometimes.
Also have you used the msm tool before?

Just one more thing, when you connect the phone to pc check your device manager to see if the PC reads the phone. If it does than its just a driver issue and reinstalling the qualcom driver for msm maybe needed.
I've found that sometimes I have to reinstall the Qualcomm drivers for EDL. So check that when you connect the phone to the PC in EDL mode there isn't an entry in Device Manager under Ports (COM & LPT)

I can't know which mode the phone is stuck on, because I have only a black screen, even the Power button with volume up / down not working,
do you think if I keep it for a couple of days the battery will drain and I can use MSM tool with press 2 volume buttons, it's the last thing i think about

I would open it up and remove the battery instead of waiting for days but that's also an option. It's not that hard to open, I opened mines to replace the usb port. I just held the back of the bottom corners of the phone over the stove until it was hot enough to soften the glue and used an old credit card and my thumb nail to open it. It maybe unrecoverable anyway so its worth a try.

I've had a totally black screen at times in Qualcomm Crashdump Mode. To get out of it you can use Power+Vol up and then, when the phone buzzes, use the key combination for bootloader or MSM.

I tried a lot to press Volume Up + Power & Volume Down + Power & the 3 buttons, but with no response.
I can't feel any buzz, even I tried it when the phone connected to the PC, no sound come from PC prove that the phone is connected
Please keep us updated with any current queries or resolution as I'm very interested in the outcome.

Hello!
If waiting for battery to discharge will not help you, i suggest of:
- Removing the back panel by heating it.
- Unplugging battery
- Then using the EDL points on the motherboard to force the device to boot EDL.
-The device immediately will be recognised by just one tap on "enum" now.
- Plugging the battery again and attaching back panel and rebooting.
