Flashing firmware at the chip level is a powerful but also potentially risky operation. MediaTek tools like SP Flash Tool require you to match the chipset model precisely. Using an incorrect firmware version designed for a different MT6765 device variant can result in a non-functional device. The following precautions are highly recommended: sp flash tool mt6765
Navigate to the SP Flash Tool folder and run flash_tool.exe as administrator (right-click the file and select "Run as administrator"). MediaTek chipsets since 2018 require a secure authentication
