[HELP]How do I unlock the bootloader on a bricked One plus 7 pro? - OnePlus 7 Pro Questions & Answers

My one plus 7 pro GM1910 is stuck in Qualcomm crashdump mode, so I can't boot up my device and Unlock the bootloader. I can access Adb fast boot but I can't do anything from there because my device is locked. I have tried the MSM download tool from this guide here. But it still keeps getting stuck at Qualcomm crash dump mode showing an error message- Atempted to kill IniT.
Is there any other way to Unlock the bootloader? I will be extremely grateful if you could help me, Thanks.

Help!!! Bricked device

I was trying to unroot I was on 9.0.4 and had magisk 17.1 and no twrp since i updated from 9.0.3 or whatever update was before. I factory reset and had no more root, and no twrp. I still had a unlocked bootloader so I went to adb and locked it and then it rebooted and gave me the red message "your device is corrupt and will not boot." it doesnt boot at all to anything not even recovery and I am just in fastboot. I tried MSMdownloadtool but it doesnt work. I am in windows test mode and tried but it would not show up on the msmdownloadtool. It doesnt connect. Also in adb it does not show up. Help me!!!!

Msm download should work now as well with your bootloader unlocked

MSM download will work.
Just download appropriate Qualcomm drivers before proceeding.
Use Volume Up while connecting to PC.
MSM should detect the device connected in any of COM ports.
Just go to this thread https://forum.xda-developers.com/oneplus-6/how-to/tool-msmdownloadtool-v4-0-international-t3798892 and follow procedures to recover your phone just like how it is when you bought your device. Also, it will lock your bootloader.

OnePlus Nord corrupt device (lock bootloder)

I just rooted the oneplus nord with magisk and then locked the bootloder and im stuck with the prompt that my device is corrupted please help me.
also i wiped internal storage and tried to unlock bootloder but it didnt worked
someone please help
Try to access the recovery by pressing volume up and power button when starting! Then choose english and choose to wipe everything! This could work if you did not flash twrp
If you have locked bootloader and unlocking from fastboot doesn't work there is no way to recover your device without and EDL flash. Please contact OnePlus Support for further information
You can find the EDL tool here https://forum.xda-developers.com/oneplus-nord/how-to/opnord-unbrick-tool-to-restore-device-t4148415. Use it to unbrick your device

[Help] Oneplus 7 pro Bricked with locked bootloader.

My one plus is stuck in Qualcomm crash dump mode, It won't boot into recovery mode, but id does boot fastboot mode, I cant use adb to flash it because my bootloader is locked, adb cant recognize my device. I have tried QDL mode to use Guac msm download tool but it does no good, Can someone tell me what am I doing wrong?
Your best bet is to read up on the msm tread. A lot of answers can be found there.
With a locked BL , I can only suggest msm tool. Personally never got it to work myself but I unlocked my BL as soon as I got my phone so I used fastboot ROM to fix it. Best of luck

Unable to unlock the bootloader

I've recently bricked my device trying to install LineageOS, long story short I had to use MSM Tool in order to flash a new, stock ROM. Since I did that I am unable to unlock the bootloader: everytime I do the phone bricks with this following Yellow message on the screen: "upgrade download failed please check your download flow is right". After that I have to use the MSM Tool again to unbrick the Yellow text.
Any ideata how I might unlock the bootloader? Aside from that, the phone works fine.
EDIT: I managed to fix this by OEM updating my device to Android 11 and *then* unlocking the bootloader. Another issue has arisen now, though: whenever I try to boot TWRP from fastboot, the phone reboots and gets stuck in the "Fastboot Mode" OnePlus logo screen. Would anyone know how to fix this, or maybe is there a way to root your phone without using a custom recovery?

Yes you can ,,install thru boot loader with ADB and fastboot CMD. First you need to extract the boot.img from your oos rom, patch it in magisk app, then put it in your adb folder and run the cmd " fastboot flash boot boot.img .
