Instructions:

Power your device off

Maintain volume up and volume down keys to get into Qualcomm EDL mode.

Launch MsmDownloadTool V4.0.exe.

Click on Enum to be sure your device is detected and press Start.

Wait ~300 seconds

Enjoy your brand new device

FAQ:

My device isn't detected when I click on "Enum" button

Go to device manager and make sure your phone shows up as QDLOADER 9008.

If it shows up as QHUSB_BULK, it means Qualcomm driver wasn't installed automatically by Windows Update. Download the latest one from Microsoft website at http://download.windowsupdate.com/c..._fba473728483260906ba044af3c063e309e6259d.cab (source https://www.catalog.update.microsof...updateid=8ee52ba0-bdef-4009-88cf-335a678dd67a ) and install it manually by right clicking on QHUSB_BULK and selecting "Update driver software" and "Browse my computer for driver software" to where you downloaded CAB file.

My device doesn't stay in EDL mode for more than 10 seconds

Some units can have this problem and there isn't a lot of things to do to fix that, except being fast after plugging your phone to your computer.

EDIT 7th August 2019: There is apparently a "one-off" solution to this problem available at https://xdaforums.com/showpost.php?p=80021106&postcount=21 . I would like to investigate more on that but sadly don't own the device so can't confirm it.

MSM tool is stuck on "Param pre-processing"

Ensure you're using the Qualcomm drivers linked in first part of this FAQ.

What is SMT Download mode?

Just don't try to unlock that mode, it will wipe your IMEI and your Widevine certificate if you use it.
