How To Unbrick OnePlus 8T with MSM Download Tool

If you have bricked your OnePlus 8T and cannot get the phone to boot up, you need to unbrick it. OnePlus 8T comes with OxygenOS 11 based on Android 11. As it is the case with every Android phone, the software that comes pre-installed on 8T can be modified and changed. The company has released the kernel source of the phone, and there will be custom ROMs and TWRP very soon.

The OnePlus 8T is the company’s latest flagship phone. It has a 6.55″ Fluid AMOLED display with a 120Hz refresh rate. There are four cameras on the back, a 48MP wide sensor, a 16MP ultrawide sensor, a 5MP macro sensor, and a 2MP depth sensor. On the inside, the phone has the Snapdragon 865 chipset with Adreno 650 GPU, 128/256GB of internal storage, and 8/12GB of RAM storage. All of this is powered by a decent 4500 mAh battery.

For the majority of users, installing a ROM and modifying the software on the OnePlus 8T goes without any trouble. However, sometimes things go wrong and users can brick the phone during the process. When the phone is bricked, users cannot enter into Fastboot mode. Fastboot is used to restore the stock firmware of the OnePlus 8T. This means that the phone is completely unusable and you need to unbrick it to bring it back to life. For this scenario, MSM Download Tool is used. MSM Download Tool is a flashing tool that unbricks bricked OnePlus devices. It uses Qualcomm’s Emergency Download Mode to flash the stock firmware on the OnePlus 8T, and subsequently unbricking it.

Note: MSM Download Tool only works on Windows computers. This means that you cannot use the tool if you have a Mac or Linux machine. You need Windows 7, 8, or 10.

There are three variants of the tool, based on your region: European firmware (KB05BA), Indian firmware (KB05DA ), and international firmware (KB05AA). Furthermore, you need to download the Qualcomm driver in order for the computer to recognize your phone and trigger the EDL mode.

  1. I downloaded msm tool for my device oneplus 8T with variant AA (KB05AA). when starting by following the steps, like nothing happened and waiting for device is there like forever and more than 5 minutes nothing happened. No reboot no nothing. I guess it failed. What else I should do? I wish someone who technically good for this doing it for me….

      • Yup, into the phone right? But the file can’t be open since unrecognized format. Install meaning I have to unzip it if it is a zip file. When downloaded into PC, opening the edl file, I could see so many things to be extracted. Which one supposed to be I have no idea.

        • Hi Ash, connect your phone to your computer using a USB cable. Then open Device Manager on your computer. If your phone shows up as QDLOADER 9008, you are good to go, and try using the tool again. If it says QHUSB_BULK, you need to install the EDL drivers, which need to be installed on the computer and not your phone (I have updated the article clarifying this).

          Download the EDL drivers from the download above. The file has the .CAB extension. Now right click on QHUSB_BULK and tap on “Update driver software” -> “Browse my computer” and select the downloaded .CAB file.

          Let me know how it goes.

  2. Hi I have a oneplus 8t but in my case it is the Chinese variant flashing a custom rom but I am interested in returning to the stock version. I have used the program but it gives me an error, help me?
