UNBRICK ONEPLUS 3T (Bootloop Fix)


1. First of fall,you need to install the Qualcomm Driver in your PC, we need to put our Windows operating system into “Test Mode”, we are doing this because we don’t want to deal with any driver installation issues in between our work.

To do this Press Start >Search >cmd and run as administrator.

2. In CMD window type this “Bcdedit.exe -set TESTSIGNING ON” press enter and restart your PC.

3. After doing the above step keep your device in the Qualcomm HS-USB Qdloader 9008 /EDL mode. For doing this you will have to use the default key combination of Qualcomm in your device. Ensure that your device is switch off then press the volume up button and connect the USB cable without pressing the power button.

More Steps

1. We will be using the “Msm8974 Download Tool.exe”, “rawprogram0.XML”, “patch0.XML”, “prog_emmc_firehose_8974.mbn” and “MPRG8974.mbn” flashers, these are the Qualcomm’s engineer files and only found in these kind of service roms. All the XML files can be restored but you have to cautious as the mbn files can not be restored. They include some vendor specification files that contain some symbols that cannot be used on cross models.

2. Right click “Msm8974DownloadTool.exe” and run it as “administrator”, this flasher is in Chinese but it’s not a big thing as we will only use 2 buttons on it “Enum” which will be identifying our EDL ports and then click Start to enable the flashing. Don’t get confused as Windows’s com port number and this tool’s numbers will be the same port and different numbers. After you click on Start,  “8974_msimage.mbn” will be sent to your device and you will hear an USB eject and plug sound from your PC.

3. Now you can close the Msm8974 Download Tool. After closing it press the power button and the volume up button together for some time which will reset Qualcomm 9006 port to 9008 again.

4. Now,Run the Msm8974 Download Tool as administrator and click “Start” again because our 9006 drivers is now installed.

5. After it finishes you will see the port line will become green that indicates that you have successfully unbricked your Oneplus 3T device.
