An MT6769Z scatter file is a specific configuration text file used for devices powered by the MediaTek MT6769 (Helio G80/G85) chipset. It acts as a memory map that tells flashing software exactly where each component of the firmware (like the bootloader or system image) should be written on the device's internal storage. Key Features and Specifications
Platform Configuration: Specifically designed for the MT6769 platform (often listed as MT6769H or MT6769Z) using EMMC storage.
Partition Mapping: Defines the layout for roughly 22 to 24 partitions, including: Preloader: The initial bootloader. Recovery: Used for system maintenance and updates. Vbmeta: Responsible for verified boot.
Userdata: The largest partition for storing personal files and app data. Data Fields: For every partition, the file specifies:
linear_start_addr and physical_start_addr: The exact memory starting point.
partition_size: The maximum allowed length for that block of data.
is_download: A flag indicating if the partition should be updated during a flash operation.
Version Control: Commonly found in versions like V1.1.1 or V1.1.2, which ensure compatibility with specific firmware revisions. Primary Use Cases
[Revised] How to use SP Flash tool to flash Mediatek firmware mt6769z scatter file
Introduction
The MT6769Z is a popular system-on-chip (SoC) designed by MediaTek, widely used in various Android devices. When it comes to flashing or modifying the firmware of these devices, a scatter file plays a crucial role. In this paper, we will explore what an MT6769Z scatter file is, its importance, and how to create and use it.
What is a Scatter File?
A scatter file is a text file that contains information about the layout of the firmware components on a device's storage. It is used by flashing tools, such as SP Flash Tool, to identify the correct locations of the firmware components, like boot, recovery, and system images, on the device's storage. The scatter file helps the flashing tool to accurately place the firmware components, ensuring a successful flashing process.
Importance of MT6769Z Scatter File
The MT6769Z scatter file is essential for:
Structure of MT6769Z Scatter File
A typical MT6769Z scatter file consists of the following sections: An MT6769Z scatter file is a specific configuration
name: Name of the partition (e.g., boot, recovery, system).offset: Starting address of the partition on the device's storage.size: Size of the partition.type: Type of the partition (e.g., boot, recovery, system).Example of MT6769Z Scatter File
Here's an example of a basic MT6769Z scatter file:
Scatter file generated for MT6769Z
header_version = 2
[preloader]
filename = preloader.bin
offset = 0x00000000
size = 0x00040000
type = preloader
[boot]
filename = boot.img
offset = 0x00060000
size = 0x00800000
type = boot
[recovery]
filename = recovery.img
offset = 0x01000000
size = 0x00A00000
type = recovery
[system]
filename = system.img
offset = 0x10000000
size = 0x68000000
type = system

Conclusion
In this paper, we have discussed the importance of the MT6769Z scatter file and provided a basic understanding of its structure and usage. By creating and using a correct scatter file, users can ensure a successful flashing process, install custom ROMs, and repair or unbrick their devices.
It is important to clarify a technical detail before providing the text you requested. The chipset MT6769Z is technically known as the Helio G85. In many SP Flash Tool directories and firmware backups, this chipset is often identified as MT6768 (Helio G80/G85) because they share the same hardware architecture and drivers. Firmware flashing : A correct scatter file ensures
If you are looking to unbrick a device (like a Redmi 9, Tecno, or Infinix) using SP Flash Tool, you need the specific scatter file that matches your device's ROM version. Using a scatter file from a different phone can permanently brick your device.
Below is a generic, template text for an MT6769Z scatter file. You can save this as MT6769_Android_scatter.txt, but you must verify the partition sizes and offsets for your specific device.
Because the MT6769Z scatter file includes PROTECTED partitions, using the standard SP Flash Tool requires a specific DA (Download Agent). The interesting trick: If you take a scatter file from a Redmi 10C (which uses the MT6769Z) and try to flash it to a Doogee N20 Pro (same chip), the flash tool will silently skip the nand_temp partition. This results in a "Ghost Brick"—the phone boots, the screen lights up, but touch is inverted on the X-axis.
A scatter file is a text file that contains information about the layout of the firmware components on a mobile device. It is used by flashing tools, such as SP Flash Tool, to identify the correct locations of the firmware components, such as the bootloader, kernel, and system image, on the device's memory.
For Linux users, traditional SP Flash Tool is no longer the only option. The open-source mtkclient (by bkerler) provides a modern alternative. The command to use an MT6769Z scatter file in Linux:
python3 mtk.py wf scatter MT6769Z_Android_scatter.txt
Or, to flash a single partition:
python3 mtk.py w boot boot.img
This tool reads the scatter file automatically if placed in the same directory.
A scatter file (.txt) is a partition table + loading address map for MediaTek (MTK) chipsets.
It tells tools like SP Flash Tool, SP Meta Tool, or MTK Client exactly where each partition (like boot, system, userdata) lives in the eMMC/UFS flash memory.
The MT6769Z is a variant of the Helio G85/G80 family (MT6769V/CZ). The scatter file is chipset-specific, not model-specific, but may vary slightly with eMMC vs UFS and storage size.
To create a scatter file for the MT6769Z processor, follow these steps:
partition_name : The logical name of the partition (e.g., boot, recovery, system, vendor).linear_start_addr : The absolute memory address where the partition begins.partition_size : The size of the partition in hexadecimal. For example, 0x400000 equals 4,194,304 bytes (4MB).region : Specifies which physical region of the chip. Options include EMMC_BOOT_1 (preloader), EMMC_BOOT_2, EMMC_USER (main storage), and EMMC_RPMB (Replay Protected Memory Block).file_name : The actual image file that should be written to that partition.
