MT6755 Scatter Files: The Blueprint of Your MediaTek Device If you have ever tried to "unbrick" a phone or flash a custom ROM on a device powered by the MediaTek MT6755 (also known as the Helio P10), you have likely encountered a
file with "scatter" in the name. While it looks like a simple text document, it is actually the master map that tells flashing tools exactly where every piece of software lives on your phone's storage. What is an MT6755 Scatter File? A scatter file is a configuration map used by the SP Flash Tool
and other Mediatek service utilities. It defines the device's partition layout—think of it as a table of contents for the eMMC (internal storage) chip. Without this file, the computer wouldn't know where the system.img ends and the recovery.img Anatomy of the Scatter File When you open an MT6755 scatter file in a text editor like , you’ll see several key parameters for each partition: partition_index: The sequential order of the partition. partition_name: Common names like linear_start_addr: The specific hex address where a partition starts. physical_start_addr: The raw hardware address on the storage chip. partition_size: How much space is allocated for that specific component. is_download:
A "true" or "false" flag that tells tools whether this section should be updated during a standard flash. Why Does This Matter? Manual Formatting:
If you need to wipe a specific part of the phone (like a forgotten pattern lock in the partition), you use the scatter file to find the Begin Address Format Length to enter into SP Flash Tool's Manual Format tab Backing Up (Readback):
To create a backup of your current firmware, you use the scatter file to tell the tool which addresses to "read back" from the device and save to your PC. Firmware Upgrades:
During a firmware update, the scatter file ensures the new software doesn't overwrite critical areas like the , which holds your IMEI and network calibration data. Pro-Tip: Match Your Chipset
The MT6755 has a specific architecture. Always ensure your scatter file starts with general: MT6755
. Using a scatter file from a different chipset (like the MT6735) can result in a "hard brick," as the tool will attempt to write data to the wrong physical addresses, potentially corrupting the bootloader permanently. from your specific MT6755 device?
How to format a single partition in Mediatek using SP Flash tool
The MT6755 scatter file is far more than a simple configuration text—it is the master partition table that defines the physical storage layout of every Helio P10 device. Whether you are recovering a bricked phone, installing a custom recovery, or developing a new ROM, understanding and correctly using the scatter file is the difference between success and an unrecoverable hardware brick. Always treat it with the same care as a BIOS or UEFI partition table on a PC.
The MT6755 scatter file is a plain text configuration file (.txt) used by MediaTek flashing software like SP Flash Tool. It acts as a detailed map for the Helio P10 (MT6755) chipset, telling the tool exactly where to write specific firmware components onto the device's eMMC storage. 🛠️ Key Functions
Partition Layout: Defines approximately 24–28 partitions, including the preloader, recovery, boot, system, and userdata.
Address Mapping: Specifies the physical start addresses (e.g., 0x0) and the partition size for each component. mt6755 scatter file
Flashing Control: Determines which parts of the firmware are downloadable or protected during a flash operation. 📂 Common Use Cases
Unbricking: Reflashing the stock ROM when a device is stuck in a boot loop or dead after a failed update.
Bypassing FRP: Manually formatting the specific FRP partition by locating its start address and length within the scatter file.
Custom Recovery: Flashing individual images like TWRP into the recovery partition. 🚀 How to Use It MT6755 Scatter File Configuration | PDF - Scribd

Feature Name: Advanced Scatter File Generator for MT6755 Devices
Description: Develop a user-friendly, desktop-based application that can automatically generate a scatter file for MT6755-based devices. This tool aims to simplify the process of creating and editing scatter files, making it accessible to both developers and end-users.
Key Features:
Benefits:
Implementation:
The application could be developed using programming languages like Python or C++, with a GUI framework such as Tkinter or Qt for the interface. It would require access to a database or a comprehensive list of MT6755 device configurations to accurately generate scatter files.
Future Enhancements:
By developing such a feature, users would have an easier time managing and flashing firmware on their MT6755-based devices, contributing to a more straightforward and less risky process of device maintenance and customization.
An MT6755 scatter file is a text-based configuration document crucial for MediaTek flashing tools to map the memory layout of devices using the Helio P10 chipset, defining physical start addresses and sizes for partitions. It instructs software on where to write firmware images, covering roughly 24 partitions including preloader, boot, and system. Detailed information and examples can be found at

Whether you are using the SP Flash Tool to revive a dead device or installing a custom ROM, the scatter file is the most critical component of the process. In this article, we’ll break down what it is, why it matters, and how to get one. What is an MT6755 Scatter File?
A scatter file is a small text document (usually .txt) that acts as a map for your device’s internal storage. MediaTek devices divide their memory into several partitions, such as recovery, system, boot, and userdata.
The MT6755 scatter file tells the flashing software (like SP Flash Tool) exactly where each part of the firmware begins and ends on the physical storage chip (eMMC). Without it, the software wouldn't know where to "drop" the files, potentially leading to a hard-bricked device. Key Information Found in a Scatter File: Platform: MT6755 Project: The specific build name for your device. Partition Index: The order of the storage blocks.
Linear Start Address: The physical starting point of a partition. File Name: The corresponding image file (e.g., system.img). Why Do You Need It?
Unbricking: If your phone is stuck in a boot loop or won't turn on, you need the scatter file to reinstall the factory firmware.
Backing Up: Before modding, developers use the scatter file to "read back" a copy of the existing partitions.
Custom Recovery: To install TWRP, you need the scatter file to target the specific recovery partition.
Bypassing FRP: Some technicians use specific addresses found in the scatter file to format the FRP (Factory Reset Protection) partition. How to Get the MT6755 Scatter File There are two primary ways to acquire this file: 1. Extracting from Stock Firmware MT6755 Scatter Files: The Blueprint of Your MediaTek
The safest way is to download the official Stock ROM for your specific device model. Once you unzip the firmware folder, the scatter file (usually named something like MT6755_Android_scatter.txt) will be located in the main directory alongside the .img files. 2. Creating One via MTK Droid Tools or Miracle Box
If you can't find your firmware online but your device still boots, you can generate a scatter file directly from the phone. Enable USB Debugging.
Connect to a PC and use a tool like MTK Droid Tools (though compatibility with Helio P10 can be hit-or-miss) or WWR MTK.
The tool reads the partition table and saves it as a text file. How to Use the MT6755 Scatter File with SP Flash Tool Using the file is straightforward, but requires precision:
Install VCOM Drivers: Ensure your PC recognizes the MediaTek Preloader interface. Open SP Flash Tool: Launch the application.
Load Scatter: Click on the "Choose" button next to Scatter-loading File.
Select the File: Navigate to your firmware folder and select MT6755_Android_scatter.txt.
Verify: The tool will automatically populate the list of partitions (Preloader, Recovery, System, etc.).
Flash: Choose "Download Only" (unless you are performing a full format) and click Download. Connect your powered-off device. Important Safety Warning
Never use a scatter file meant for a different chipset or even a different phone model.
Even if two phones both use the MT6755 (Helio P10) chip, their partition sizes—like the preloader—might differ. Using the wrong scatter file can result in a "Hard Brick," where the device will no longer communicate with the computer at all. Always verify your Hardware Version before proceeding. Conclusion
The MT6755 scatter file is the bridge between your computer and your phone's hardware. By understanding its structure and ensuring you have the correct version for your specific device, you can safely perform deep-level maintenance and customization on your Helio P10 device.
