MT8167 scatter file is a critical text-based configuration file ( ) used by MediaTek's SP Flash Tool
to map the memory layout of devices powered by the MT8167 chipset. It defines the exact boundaries, names, and addresses for every partition on the device's eMMC storage. rigacci.org Key Sections of the Scatter File
A typical MT8167 scatter file includes the following core components for each partition: partition_index : The sequential number of the partition (e.g., partition_name : The functional name, such as linear_start_addr
: The specific hex address where the partition begins in flash memory (e.g., partition_size
: The total length of the partition, used by tools to ensure image files do not exceed allocated space. is_download : A boolean flag ( ) determining if the partition can be flashed by the tool. : Typically set to HW_STORAGE_EMMC for MT8167 devices. rigacci.org Typical Partition Layout The MT8167 chipset generally supports between 22 and 26 partitions . Standard layouts include: Bootloaders (Little Kernel), and (TWRP or Stock), and Vendor & Data Device-Specific (IMEI/calibration data), (Factory Reset Protection). Common Use Cases Flashing Firmware : Loading the scatter file into SP Flash Tool
tells the program exactly where to write each component of the stock ROM. Readback/Backups : Users can use the linear_start_addr partition_size
to "read back" specific partitions to a PC, creating a full firmware backup. Unbricking : If a device is stuck in a boot loop, flashing the correct
partitions via the scatter file is often the first step in recovery. Generation Tools

MT8167 scatter file is a text-based configuration file used by MediaTek's SP Flash Tool
to define the memory layout of an Android device. The "top" or header of this file contains critical metadata that dictates how the flashing tool interacts with the device's hardware, specifically its eMMC or storage controller. Header Structure & Key Parameters The top of an MT8167 scatter file typically begins with the config section, which includes: Config Version for newer MT8167 chipsets. : Identified as : The specific internal project name (e.g., full_mt8167 : Defines the storage type, almost always for this chipset. Boot Channel : Usually set to for eMMC boot. Block Size : Defines the physical block size, often First Partition Blocks
Immediately following the general configuration, the file lists the early-stage boot components. These are the most sensitive partitions because they handle the initial hardware initialization: : The very first block. It has no linear_start_addr
because it resides in a special boot partition of the eMMC rather than the main user data area. PGPT (Primary GUID Partition Table) : The "map" of the rest of the storage. Recovery/Boot : Often the first partitions with a defined linear_start_addr Usage Context When using the scatter file in SP Flash Tool mt8167 scatter file top
, the header ensures the tool doesn't attempt to flash a ROM intended for a different chipset (like the MT8163), which would result in a "PMT changed" error or a hard brick. If you are performing a (dumping firmware), you must copy the linear_start_addr partition_size
from these top sections to correctly target the data you want to extract. TWRP port for MC Smart · Issue #38 - GitHub
In the world of Android firmware development and device maintenance, the MT8167 scatter file is a critical configuration document that acts as a blueprint for the device's storage. Specifically used for devices powered by the MediaTek MT8167 chipset—a quad-core processor common in tablets and smart home devices—this file dictates exactly how data is organized across the physical memory. The Anatomy of an MT8167 Scatter File
A scatter file (typically named MT8167_Android_scatter.txt) is a plain-text file that maps out the partition layout of the device. It provides a bridge between the raw binary images of the operating system and the physical addresses on the eMMC or UFS storage.
The "top" of the file usually contains general platform information, followed by individual sections for each partition, including:
Preloader: The initial bootloader that initializes the hardware. Boot: Contains the Android kernel and ramdisk.
Recovery: The emergency interface used for system repairs or updates.
System/Vendor: The core operating system files and manufacturer-specific drivers.
Userdata: The largest partition, reserved for user apps and data. Critical Data Fields
Each partition entry in the scatter file contains several mandatory parameters that tools like the SP Flash Tool use to execute commands:
linear_start_addr: The logical starting point of the partition.
physical_start_addr: The actual hardware address on the memory chip. MT8167 scatter file is a critical text-based configuration
partition_size: The maximum allowed size for that specific block of data.
is_download: A flag that tells the flashing tool whether to write this partition by default. Practical Applications
The primary utility of the MT8167 scatter file is in unbricking or upgrading devices. When a tablet becomes stuck in a boot loop, a technician uses the scatter file to "scatter" the correct software components back into their designated slots on the hardware. Beyond simple flashing, these files are essential for:
FRP Bypass: By identifying the exact memory address of the Factory Reset Protection (FRP) partition, users can format or clear that specific block to regain access to a locked device.
Custom Recovery: Developers use the scatter file to ensure a custom recovery like TWRP is flashed to the precise recovery partition address without overwriting critical system data.
Backups: Tools like WWR MTK can read the partition table from a working device and generate a scatter file to create a perfect clone of the firmware.
Understanding the structure of the MT8167 scatter file is the first step for anyone looking to perform deep-level software modifications or repairs on MediaTek-based hardware. Android Partitions on MTK Devices - rigacci.org
The MT8167 scatter file is a text-based roadmap used by SP Flash Tool to understand the memory structure of devices running on the MediaTek MT8167 chipset. It defines exactly where partitions like the preloader, recovery, and system reside in the device's eMMC storage. 🛠️ Key Components of an MT8167 Scatter File
A typical scatter file for this chipset contains approximately 25 to 26 partitions. Each entry includes:
Partition Name: Identifiers like PRELOADER, RECOVERY, or SYSTEM.
Physical Start Address: The hexadecimal location on the eMMC where the partition begins.
Partition Size: The total allocated space for that specific block. general: Defines the MTK platform code
Is Download: A boolean (true/false) telling the flash tool if this part should be written to the device.
Operation Type: Usually set to UPDATE or INVISIBLE depending on the partition's role. 📂 Common Use Cases You will primarily need an MT8167 scatter file for:
Firmware Flashing: Installing or updating the Stock ROM using tools like SP Flash Tool.
Unbricking: Restoring a "dead" tablet or smart device that no longer boots.
Bypassing FRP: Locating the physical address of the Factory Reset Protection (FRP) partition to format it manually.
Creating Backups: Using the addresses in the scatter file to "Read Back" and dump the device's current firmware. 🚀 How to Obtain or Generate One
It is always best to use the scatter file included in your specific device's official firmware. If you don't have it, you can:

Creating a guide for the "mt8167 scatter file top" involves understanding what a scatter file is, its purpose in the context of MT8167 (a chipset used in various Android devices), and how to work with it. The MT8167 is a processor by MediaTek, commonly found in entry-level to mid-range smartphones and tablets.
The top of the file typically contains general settings:
tb8167p3_64_bsp).1.1 or 1.2.block_size: 0x20000Defines the logical block size in bytes. 0x20000 = 131,072 bytes = 128 KB. MTK tools use this to calculate partition offsets. Do not modify this unless you have explicit documentation from the SoC vendor.
