Installation of SP Flash Tool & Drivers:
Download all the Zip files and unzipped accordingly.

The Fastboot Rom may be tricky, this one you need to use winzip to unzip, then use 7-zip to unzip the .tgz file.

Next, you need to install drivers in order to connect your device properly, just extract "Driver_Auto_Installer_v1.1236.00.zip", and double-click "Install.bat", and it will automatically install the necessary drivers, and allow permissions for these drivers to be installed.

Unzipped, both SP_Flash_Tool_exe_Windows_v5.1620.00.000.zip and omega_images_6.8.11_20160805.0000.29_6.0_cn.tgz.

Once in the SP Flash Tool, click on the "Download Agent" and locate "MTK_AllInOne.bin" from the unzipped SP Flash Tool folder earlier and click Open, as shown below:

Next click on the "Scatter loading" button and locate the "MT6797_Android_scatter" from the unzipped "omega_images_6.8.11_20160805.0000.29_6.0_cn" folder earlier and click Open, as shown below:

Now turn your Redmi Pro Off.

Connect the USB to the PC/ Laptop, and the other end (USB C) dont connect to phone first.

Now click the "Download" button.

PRESS and HOLD Volume Down, keep holding it and immediately plug in your USB C to the phone.

You will immediately see the progress bar going Red, Purple momentarily, and Yellow for a few minutes until the flashing process is complete, as shown below:
