MT6589 Android scatter emmc.txt file is a critical map used by the SP Flash Tool
to communicate with MediaTek MT6589 processors. It identifies the exact memory addresses for partitions like the preloader, recovery, and system on a device’s eMMC storage. What is a Scatter File?
In the MediaTek ecosystem, a scatter file is a text-based configuration that tells the flashing software where each component of the firmware should be written. For the MT6589—a popular quad-core chip from the early Android era—this file ensures that the bootloader doesn't accidentally overwrite critical system data. Key Components of the MT6589 Scatter File A standard MT6589_Android_scatter_emmc.txt contains several defined blocks. Common sections include: Usually specific to the phone model (e.g., HEXING89_WET_JB2 Storage Type: (distinct from older NAND-based chips). Partition Index: Each partition is assigned a name (e.g., Linear Start Address: The physical starting point on the eMMC chip. Physical Start Address:
Often matches the linear address in newer eMMC configurations. Partition Size:
The maximum amount of space allocated for that specific file. How to Use It Preparation
: Download the correct firmware for your specific device. You can often find these shared on community repositories like XDA Developers SP Flash Tool , click on Scatter-loading , and select your Verification
: The tool will automatically populate the list of partitions based on the addresses in the text file.
: Once the scatter file is verified, you can proceed to flash or "read back" (backup) the device's memory.
Using a scatter file intended for a different device—even if it uses the same MT6589 chip—can result in a hard brick
. Different manufacturers allocate partition sizes differently (e.g., a 4GB storage model will have different addresses than an 8GB model). Always verify the name inside the file before proceeding. Do you need help generating
a new scatter file from a working device, or are you looking for a specific firmware for a particular phone model?
Understanding the MT6589 Android Scatter File: A Technical Deep Dive
In the world of MediaTek (MTK) device modding, few files are as critical as the MT6589 Android Scatter emmc.txt. If you have ever tried to unbrick a phone, flash a custom ROM, or perform a full ROM dump using the SP Flash Tool, you’ve encountered this specific text document.

At its core, a scatter file is a configuration script that tells the SP Flash Tool exactly where each component of the Android operating system should be written on the EMMC (Embedded MultiMediaCard) storage.
Without this file, the flashing software has no idea where system.img ends and recovery.img begins. Using the wrong scatter file is the fastest way to "hard brick" a device, as it can lead to overlapping partitions or overwriting the critical Preloader. Key Components of the Scatter File
When you open an MT6589_Android_scatter_emmc.txt in a text editor like Notepad++, you will see a structured list of partitions. Each entry typically includes:
Partition Name: (e.g., PRELOADER, BOOTIMG, RECOVERY, ANDROID)
Linear Start Address: The physical hex address on the EMMC where the partition starts.
Physical Start Address: Usually mirrors the linear address for EMMC devices.
Partition Size: How much space is allocated for that specific image.

MediaTek USB VCOM Drivers: Essential for the computer to communicate with the phone while it is powered off. Scatter files are critical for device flashing: they
SP Flash Tool: The official utility for flashing MediaTek firmware.
Stock Firmware: A ROM folder specific to your exact device model that contains the scatter file and the corresponding image files (.img, .bin).
Battery Charge: Ensure the device has at least 70% battery to prevent it from turning off during the process. 2. How to Use the Scatter File
The scatter file acts as a map, telling the tool exactly where each part of the software (like the kernel or system) should be written in the phone's internal memory (eMMC). How To Flash MediaTek Phones Using SP Flash Tool
The "MT6589 Android scatter emmc.txt" file serves as a critical mapping file for the SP Flash Tool, identifying partition locations (e.g., PRELOADER, RECOVERY, ANDROID) on eMMC storage for MediaTek MT6589 devices. This text-based configuration ensures correct data placement during firmware flashing or device recovery, particularly when using the "Firmware Upgrade" or "Download" modes.
Purpose & significance
- Scatter files are critical for device flashing: they instruct flashing utilities how to write individual partition images to eMMC/NAND.
- For MT6589, correct offsets and partition sizes are essential to preserve bootloader, radio/NVRAM, and user data integrity.
- Mistakes in the scatter can brick devices (overwrite preloader or eMMC control areas) or lead to mismatched partitions that prevent boot.
Using the Scatter File:
- Open SP Flash Tool →
Scatter-loading→ selectMT6589_Android_scatter_emmc.txt - The tool auto-populates the partitions.
- Options:
- Download Only: Writes only selected partitions (safe for updates)
- Firmware Upgrade: Wipes NVRAM, PRO_INFO (dangerous – will lose IMEI)
- Format All + Download: Extreme danger – erases PRELOADER → dead device
B. Porting Custom ROMs (LineageOS 13/14.1)
For MT6589, custom ROM developers use the scatter file to repartition eMMC for larger system sizes (e.g., expanding /system from 360MB to 800MB by shrinking /usrdata). This requires editing the scatter file and using a patched preloader.
eMMC (embedded MultiMediaCard)
- eMMC: Stands for embedded MultiMediaCard. It's a type of storage used in many mobile devices, including smartphones and tablets. eMMC combines flash memory and a flash controller in the same package, providing a cost-effective, compact storage solution.
1. Executive Summary
The file MT6589_Android_scatter_emmc.txt is not merely a text document; it is the architectural blueprint for a smartphone's memory. In the context of the MediaTek MT6589 processor—a chipset that powered millions of mid-range Android devices in the early 2010s (such as the Samsung Galaxy Grand, Lenovo models, and various "phablets")—this file served as the map used by flashing tools to navigate the device's internal storage. Without this "scatter file," a device is effectively a brick, unable to locate its own operating system or bootloader.
Challenges and Considerations
Working with scatter files and flashing devices carries inherent risks, including the potential for bricking a device if the process is not carried out correctly. Therefore, it's crucial to approach any modifications with caution and ensure that one is working with the correct and compatible scatter file for their specific device.
7. Extracting the Scatter File from an MT6589 Device (Without Firmware)
If you have a working MT6589 device but lost firmware, you can pull the scatter info from /proc/dumchar_info (if present) or use parted on eMMC:
adb shell
su
cat /proc/dumchar_info
Output example:
Part_Name Size StartAddr Type
preloader 0x40000 0x0 2
dsp_bl 0x40000 0x40000 2
...
Convert StartAddr from decimal (if shown) to hex, and Size from bytes to hex. That gives you a raw scatter mapping.
Alternatively, use MTK Droid Tools (legacy Windows software) to automatically generate MT6589_Android_scatter_emmc.txt.
Quick checklist before use
- Verify device model and eMMC type.
- Backup entire eMMC (including MBR/preloader).
- Validate partition addresses vs. device-reported table.
- Confirm file signatures and sources.
- Test on non-critical hardware first.
