Mt6769 Scatter File [exclusive] Online

For the MediaTek (also known as Helio G70, G80, or G85), the scatter file

a critical text document that defines the device's storage partition layout

. It acts as a map for flashing tools to identify where specific firmware components (like the bootloader, recovery, or system) are located in the memory. Where to Find the MT6769 Scatter File

Scatter files are typically bundled within the official firmware package for your specific device model. You can find these on documentation and file-sharing sites like: : Detailed configuration guides for MT6769 Android Scatter (New Format) MT6769 Scatter File Details Firmware Repositories : Sites like

, or your device manufacturer's support page often provide the full firmware package containing the scatter file. Key Partition Details

A typical MT6769 scatter file identifies roughly 22–28 partitions. Key entries include:

: The initial bootloader responsible for initializing the hardware. Boot & Recovery : Contains the kernel and recovery images (e.g., TWRP). : Used for verified boot verification. : The largest partition for your apps and personal data. How to Use It Tool Selection SP Flash Tool to load the scatter file for flashing firmware. : Open SP Flash Tool, click next to "Scatter-loading File," and select your MT6769_Android_scatter.txt mt6769 scatter file

: To initiate the flash, you often need to power off the device and hold Volume Down

, or both while connecting the USB cable to enter "BROM mode". Generating a Custom Scatter File

If you cannot find the file online, you can attempt to generate one from a working device using tools like MTK Droid Tools by reading the "Blocks Map" of the connected device.

: Always ensure the scatter file matches your specific device model and region exactly. Using the wrong file can lead to a hard brick (permanent software damage). specific firmware

What is the MT6769?

The MT6769 is the hardware platform code for the popular MediaTek Helio G70 and G80 chipsets. These mid-range processors are found in devices like: For the MediaTek (also known as Helio G70,

Xiaomi Redmi 9 / Redmi 9A / Redmi 9C
Realme C3 / Narzo series
Tecno and Infinix budget models

Because the hardware architecture is specific to this chipset, you cannot use a scatter file meant for an MT6735 or MT6765 (Helio P35) on an MT6769 device. Doing so results in a "BROM Error" or, worse, a permanently bricked device.

4. Region Types & Boundary Checks

The region tag is vital for eMMC management in MT6769 devices.

To understand the MT6769 scatter file, one must view it not just as a text document, but as the master architectural blueprint for devices powered by the MediaTek Helio G80 and G85 chipsets. The Core Concept: The "Map" of the Phone

A scatter file (.txt) acts as a precise geographical map of a device's internal eMMC or UFS storage. It tells flashing software, like the SP Flash Tool, exactly where every "province" (partition) of the operating system begins and ends in the memory. Anatomy of an MT6769 Scatter File

The MT6769 version (specifically V1.1.1 or V1.1.2) is designed for modern, mid-range MediaTek platforms. Inside, you will find several critical "territories" defined: Xiaomi Redmi 9 / Redmi 9A / Redmi

C. Creating Custom ROMs and Backups

Developers use the scatter file to extract individual partitions from a full flash dump. Using tools like Wwr_MTK or mtkclient, the scatter file allows you to pull only the boot or recovery partition without dumping the entire 64GB eMMC.

Tools to Generate/Edit MT6769 Scatter

WWR MTK (Windows) – create scatter from backup images.
MTK Droid Tools (deprecated, but works for old firmware).
Notepad++ / VS Code – manual edits (checksums, partition names).

1. The Basic Anatomy of the MT6769 Scatter File

Open a standard MT6769_Android_scatter.txt in Notepad++ or any hex editor. You will notice a hierarchical structure. Here is a real-world snippet:

- general : MTK_PLATFORM_CFG
  info: 
    platform: MT6769
    partition_name: PRELOADER
    linear_start_addr: 0x0
    physical_start_addr: 0x0
    partition_size: 0x40000
    region: EMMC_BOOT_1

Key Fields Explained:

linear_start_addr: The absolute address in the storage chip.
partition_size: Hexadecimal size (e.g., 0x2000000 = 32MB).
region: Defines the physical region—EMMC_BOOT_1 (Bootloader area), EMMC_USER (User data area), or EMMC_BOOT_2.
file_name: The actual binary file to flash (e.g., lk.bin, boot.img).

2. Critical Partitions in the MT6769 Layout

Unlike older MT67xx chips, the MT6769 uses a dynamic partition structure for Android 10/11/12 (Super partition). However, the scatter file still lists legacy linear partitions. Here are the crucial ones:

| Partition Name | Typical Size | Function | | --- | --- | --- | | preloader | 256KB | Low-level bootROM code. If corrupted, device = hard brick. | | lk | 1MB | Little Kernel (U-Boot variant). Handles boot selection and fastboot. | | tee | 5MB | Trusted Execution Environment (Widevine L1, secure storage). | | boot | 32MB | Kernel + ramdisk. Modifying this roots the device (Magisk). | | dtbo | 8MB | Device Tree Blob Overlay (display, touch, sensors). | | vbmeta | 8KB | Verified Boot metadata. Disable vbmeta to allow custom images. | | super | Dynamic | Logical partition containing system, product, vendor. | | userdata | Remaining | User apps, settings, internal storage. | | metadata | 16MB | Encryption key storage (FBE – File Based Encryption). |

Note on super partition: The scatter file will list super as a contiguous block. Inside the device, it is managed by the dm-linear driver. To repartition an MT6769, you edit the super size, not individual system partitions.
