According to my screenshot, I saved my Rom in my Desktop.
Select the scatter file with name - MT6592_Android_scatter.txt

Wait till it completely loads up on the SP flash tool programs.

4. On the SP Flashtool, where you see Download only, click and change it to FIRMWARE UPGRADE

Use our Screenshot below for reference:

5. Click DOWNLOAD icon, then plug the USB cable to the PC and your phone, Now Power OFF your Device (Hot Note).
Seconds later, some readings will display on the SP flash tool.

7. When the Process is Complete and successful, Youll get a Check Mark in the Flashtool on your PC, now you can unplug your phone.

Power ON the device, Keep calm as this will take a while since its the first time.
