How to Use

🔹 Part 1: Preparing Files for Flashing

● Select DA (Download Agent)

• Ensure that the Download Agent (DA) is loaded in the tool.
• Use the "Choose" button next to the Download-Agent label to load MTK_AllInOne_DA.bin.
• The DA detects the target’s flash type and handles downloading the built image to the flash memory.
• Generally, MTK_AllInOne_DA.bin is included in the tool's folder.

● Select Scatter File

• Choose the correct scatter file based on the chipset of the device (e.g., MT6799_Android_scatter.txt).
• Load it using the "Choose" button next to Scatter-loading File or select from history.
• This file notifies SP Flash Tool which type of smartphone chip will be operated.

● Assign Images

• Once the scatter file is loaded, all image files in the folder are loaded automatically.
• You can manually select a specific ROM/image file by clicking the ROM field and browsing for it.

● Select Download Scene

• Choose the appropriate download method before starting:

• Download Only

• Function: Downloads all selected images.

• Format All + Download

• Function: Formats the entire flash and then downloads all images.

• Firmware Upgrade
