Mt6755 Scatter File

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?

Technical Write-Up: MT6755 Scatter File Creation and Structure

Practical examples

  1. Updating only recovery:

    • Set is_download: true for RECOVERY and false for others; file_name = recovery.img.
    • Flash with SP Flash Tool in "Download Only" mode.
  2. Expanding userdata partition:

    • Adjust partition_size for USRDATA to a larger hex value in the scatter, then repartition (risky — backup first).
    • Example: change partition_size from 0x3D880000 to 0x4D880000.
  3. Extracting partition offsets:

    • Use linear_start_addr to compute absolute offsets for raw dd operations if you can access eMMC from a host: offset = linear_start_addr in bytes.

MT6755 Scatter File Configuration | PDF | Computer Data - Scribd

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.
