The MT6761 (MediaTek Helio A22) scatter file is a critical text-based configuration file used by tools like the SP Flash Tool to map out a device's partition layout for firmware flashing or repair. Core Structure of the Scatter File
- Always verify
ddr_size matches the target device’s RAM.
- Never change
page_size or block_size unless rebuilding from a known-good EMMC specification.
- Retain
PRELOADER 0x0 exactly as shown.
- Use
partitions: with_name to ensure compatibility across firmware revisions.
Success: Wait for the green "OK" circle to appear before disconnecting. Where to Find the Right Scatter File

- general: MTK_PLATFORM_CFG
info:
- config_version: V1.1.2
platform: MT6761
project: [Project Name]
storage: EMMC
boot_channel: MSDC_0
block_size: 0x20000 Use code with caution. Copied to clipboard (Note: Values like config_version may vary by device manufacturer.) Key Header Fields config_version : The version of the scatter file format (e.g., V1.1.2). to match the chipset. : Defines the storage type, usually for this chipset. block_size
# Boot Channel: EMMC
- Meaning: The boot device type. Possible values:
EMMC, UFS, NAND.
- For MT6761: Always
EMMC because the SoC does not include a UFS controller.
C. Proinfo & NVRAM (Top of User Data)
These contain device-unique identifiers. If you flash a blank proinfo from a generic MT6761 scatter file, you will lose your IMEI.
- The
platform string is checked against a hardware fuses.
- Modified
PRELOADER address triggers boot ROM signature verification failure.
- Some OEMs embed a CRC32 checksum of the top section into the scatter file’s first line (not visible in plaintext).
