Be it for flashing custom binaries, TWRP, or custom ROMs, there’s a lot to try out. Likewise, you could also gain administrative privileges by rooting your device via Magisk patched boot.img. However, each of these tweaks does bring in a few uninvited risks as well. Then the matter gets further complicated when we bring in the device’s A/B Partition into the picture. All in all, chances of things going south are always there. If it is a soft brick or bootloop, then you could easily fix it by flashing the OxygenOS stock firmware via Fastboot Commands. But in the case of hard bricked, you would have to take the help of Qualcomm’s special Emergency Download Mode to force-flash the firmware onto your device. And in this guide, we will show you how to do just that. So without any further ado, let’s get started with the guide to unbrick the OnePlus 7/7 Pro /7T and the 7T Pro devices using MSM Download Tool.

STEP 1: Disable Firewall/Antivirus
Many users have reported that they were unable to use the tool because Windows Defender or Antivirus app conflicted with the tool. So it’s better to temporarily disable them. Here is how to do so on Windows Defender:
STEP 2: Disable Windows Driver Signature Verification
You will also have to disable the Driver Signature Verification on your Windows PC so that you could install unsign driver Qualcomm (mentioned in the next step) and the MSM Tool. So refer to our guide to Disable Driver Signature Verification on Windows 10.
STEP 3: Install Qualcomm HS-USB QDLoader 9008 Drivers
Next up, you would require the drivers so that your PC is able to recognize the connected device in EDL Mode. As a result, your device will then be recognized as Qualcomm HS-USB QDLoader 9008 by the Device Manager.
However, if you don’t install these drivers, then your PC wouldn’t be able to identify the connected device and the Device Manager would list pout the device as QHUSB_BULK. So refer to our guide to Download and Install Qualcomm HS-USB QDLoader 9008 Drivers.
STEP 4: Download MSM Download Tool for OnePlus
As opposed to other tools, MSM doesn’t come as a standalone tool. Rather it comes bundled with the firmware file as well. So you should only use the MSM Tool that corresponds to your device. If you wish to use it for any other device for whatever reason (though not recommended), then make sure to replace the OPS firmware with the one for your device.

Unbrick OnePlus 7/7T/7T Pro via Fastboot Enhance
This is a tool created by XDA Senior Member xzr467706992 and beholds a slew of intriguing features, including the ability to directly flash the payload.bin file, without the need to even manually extract it first. Do note that even though this tool was created for OnePlus 8T but it should work across other OnePlus devices too. [Well, I have personally tested it on OnePlus 7T and OnePlus 10 Pro, it works well and good even on those devices]. Moreover, as is evident from the tool’s name, it will only work if you could at least access the Fastboot Mode, which is a possibility when your device is soft brick or in a bootloop mode. However, if your device is completely bricked [in EDL Mode], then this method would not work [unless you could aces Fastboot Mode somehow] and you will have to ty out the MSM Download Tool method mentioned above.
STEP 1: Download Fastboot Enhance Tool
Download the Fastboot Enhance Tool from GitHub [direct link]. Once downloaded, extract it to any convenient location on your PC. The biggest advantage of this tool is that you could directory flash the payload.bin file, there is no need to extract it and get the resultant IMG files!
STEP 2: Download OnePlus OnePlus 7/7T/7T Pro ROM
STEP 3: Install Android SDK
Next up, install the Android SDK Platform Tools on your PC. This is the official ADB and Fastboot binary provided by Google and is the only recommended one. So download it and then extract it to any convenient location on your PC. Doing so will give you the platform tools folder, which will be used throughout this guide.
STEP 4: Install Fastboot Drivers
The tool doesn’t come with the Fastboot Drivers, so you will manually have to install it on your PC. For that, please refer to our guide on How to Install Fastboot Drivers in Windows 11. Likewise, make sure to install the OnePlus USB Drivers as well [they are usually automatically installed as soon as you connect your device to the Windows PC for the first time].
STEP 5: Boot to Fastboot Mode
STEP 6: Flash Downgrade Firmware on OnePlus 7/7T/7T Pro via Fastboot
