Cause: You are using an SP Flash Tool older than v5.20 on an MT6761 with DA (Download Agent) security.
Fix: Download SP Flash Tool v5.2128 or newer, which includes support for mt6761_sys_dl.bin.
Part 1: What is an MT6761 Scatter File?
A scatter file (formally known as a "scatter loading file") is a plain text configuration file that describes the memory layout of a device’s flash storage (eMMC or UFS). It tells the flashing tool exactly where to write each partition: the bootloader, system, recovery, user data, etc.
For the MT6761, the scatter file is device-specific. While the chipset is the same, different phone models (e.g., Redmi 7A vs. Tecno Spark 4) have different partition sizes and partition names.

11. Extracting Scatter File from Stock ROM
To obtain a factory-correct scatter file:
- Download stock firmware (
pac or ofp or zip format).
- Use
MTK_Pac_Extractor or mkimage to unpack.
- Locate
MT6761_Android_scatter.txt inside extracted folder.
- Validate against device’s partition sizes using:
adb shell cat /proc/partitions
adb shell ls -l /dev/block/by-name/
Best practices
- Use the scatter file provided by the device vendor or the exact firmware package.
- Backup NVRAM and partition table before making changes.
- Avoid flashing PRELOADER unless you have a verified, device-specific preloader and a recovery plan.
- Keep a copy of the original scatter file and device-specific documentation.
- Work on a stable power source and use official cables to avoid interruptions mid-flash.
Conclusion
A scatter file for MT6761 is a critical mapping file that instructs MediaTek flashing tools how to place firmware components on a device’s storage. It is device-specific and powerful—used correctly, it enables firmware updates and recovery; used incorrectly, it can permanently damage the device. Always use the exact scatter that matches your device and take backups of sensitive partitions (especially NVRAM) before flashing.

The MT6761 scatter file is a technical configuration text file (usually named MT6761_Android_scatter.txt) used by MediaTek's SP Flash Tool to define the structure of a device's storage. It acts as a roadmap for the flashing software, identifying where specific firmware components like the bootloader, recovery, and system images should be written on the eMMC memory. Core Functions of the MT6761 Scatter File The Ultimate Guide to the MT6761 Scatter File:
Partition Mapping: Defines the physical start address, length, and region (e.g., EMMC_USER, EMMC_BOOT_1) for each partition.
Component Identification: Maps human-readable names (like system or userdata) to specific partition indexes used by the hardware.
Flashing Instructions: Specifies whether a partition is "downloadable" (can be flashed), "upgradable," or should be ignored during a standard firmware update.
Device Verification: Ensures that the firmware being loaded is compatible with the MT6761 (Helio A22) chipset platform to prevent "bricking" the device. Structure of the File it enables firmware updates and recovery
A standard MT6761 scatter file typically contains 23 to 24 partition entries. Key partitions found in these files include:
Preloader: The initial bootloader that initializes the hardware and allows the SP Flash Tool to communicate with the device.
Recovery: Contains the recovery image used for system repairs or factory resets.
System/Vendor: The primary OS files and hardware-specific drivers.
Userdata: The partition where personal files and app data are stored. MT6765 Android Scatter Configuration | PDF | Data - Scribd
