How to Unbrick Dead OnePlus 6 Using MSM Download Tool

A big thanks to SkandaH (XDA Portal Supporter) for sharing the unbrick firmware file (OxygenOS 5.1.5 which can be upgraded to the latest OxygenOS version by flashing full signed zip. Before jumping into the method, follow some of the requirements we’ve provided below. You’ll need a Windows computer and a USB cable for this.

1. Turn Off Windows Defender and Firewall

First of all, you should disable the Windows Defender and Firewall protection on your computer temporarily to easily proceed to the firmware flashing steps. Otherwise, these security programs may block the MSM Download Tool from running properly. To do so:

Press the Windows + I keys to open Windows Settings > Click on Privacy and Security.
Go to Windows Security > Click on Virus & threat protection.

Click on Manage settings >Then turn off the Real-time Protection option.
Once done, make sure to reboot your PC to apply changes.
Next, click on the Start menu > Type Control Panel and open it.
Type firewall in the search box and open Windows Firewall.

Then click on Turn Windows Firewall on or off.
Select Turn off Windows Firewall for the Private, Domain, and Public Network Settings.

Once turned off, make sure to reboot the PC to apply changes.

Keep in mind that if you’re using another third-party antivirus software then turn it off until the unbricking methods get completed. It’s necessary.

2. Disable Driver Signature Enforcement

The second thing you should do is simply disabling the Windows Driver Signature Enforcement on the PC. Otherwise, this feature may not allow you to easily install any of the third-party not-signed Qualcomm drivers as well as the MSM Download Tool on the computer. To do this:

Press the Windows + X keys to open the Quick Link Menu.
Click on Command Prompt (Admin) or Windows Terminal (Admin) from the list.
Now, copy/paste the following command line in the command prompt window and hit Enter to execute it:

bcdedit /set testsigning on

If you see the message ‘The operation completed successfully.’ then just restart your computer to boot it into the ‘Test Mode’.
- However, if you see a message ‘Protected by Secure Boot policy’ that means the Secure Boot feature is enabled on your computer.
- In that scenario, you’ll have to disable the secure boot in the UEFI firmware option that can be found in the BIOS settings. [There are plenty of tutorials available online]

Please Note: Once the unbricking process is done, make sure to run the bcdedit /set testsigning off command to turn off the Test Mode on your PC.

3. Install Qualcomm HS-USB QDLoader 9008 Drivers

Next, you’ll have to simply install the Qualcomm HS-USB QDLoader 9008 Drivers on your Windows PC manually so the OnePlus 6 will easily get detected while connected to the PC via a USB cable. We’ve already provided a full guide to install Qualcomm HS-USB driver that you should perform accordingly.
