5. Procedural Methodology

This section outlines the standard operating procedure for flashing the Symphony i95 4G.

Prerequisites:

  • Hardware: Symphony i95 4G device, USB Data Cable, Windows PC.
  • Software: SP Flash Tool (Smart Phone Flash Tool), MTK VCOM Drivers, Symphony i95 Stock ROM (Scatter-based).

Execution Steps:

  1. Driver Installation: Install the MTK VCOM Drivers to ensure the OS recognizes the device when it enters BROM mode.
  2. Tool Configuration: Launch SP Flash Tool. Navigate to the "Download" tab and load the Scatter File (MT6739_Android_scatter.txt).
  3. Selection: Ensure partitions "Preloader," "Boot," "System," and "Userdata" are selected. Deselecting "Preloader" is a safety measure to avoid hard-bricking, though it is required for a full unbricking.
  4. Initiation: Click "Download." Connect the powered-off device to the PC.
  5. Completion: The tool will indicate a successful flash with a green checkmark circle. The device will then reboot (first boot may take 5-10 minutes to optimize apps).

Step 1: Install MediaTek Drivers

  1. Download and extract MTK VCOM drivers.
  2. Disable Windows Driver Signature Enforcement (for Windows 10/11).
  3. Run InstallDriver.exe as administrator.
  4. Connect your powered-off phone via USB. Windows should detect MediaTek Preloader USB VCOM Port.
