What is a Scatter File?
A scatter file is a text file used in the flashing process of Android devices, particularly those with MediaTek (MTK) processors. It contains information about the layout of the device's storage, including the starting addresses and sizes of various partitions.
MT6755 Scatter File
The MT6755 is a 64-bit octa-core processor from MediaTek, commonly used in mid-range Android devices. A scatter file for the MT6755 processor typically contains the following information:
- Partition layout: The scatter file defines the partition layout of the device's storage, including the sizes and starting addresses of partitions such as:
- Boot
- Preloader
- Uboot
- Trust
- Keystore
- System
- Vendor
- Oem
- Cache
- userdata
- Memory layout: The scatter file also defines the memory layout of the device, including the base addresses and sizes of:
- RAM
- ROM
Example of an MT6755 Scatter File
Here's an example of a basic scatter file for an MT6755 device:
MEMORY
RAM (x): 0x40000000, 2048M
ROM (x): 0x00000000, 4096M
PARTITION
name = boot, size = 20M, offset = 0x00000000
name = preloader, size = 1M, offset = 0x10000000
name = uboot, size = 8M, offset = 0x11000000
name = trust, size = 4M, offset = 0x18000000
name = keystore, size = 2M, offset = 0x1C000000
name = system, size = 1024M, offset = 0x20000000
name = vendor, size = 256M, offset = 0x34000000
name = oem, size = 128M, offset = 0x38000000
name = cache, size = 128M, offset = 0x3C000000
name = userdata, size = 2048M, offset = 0x40000000
Uses of a Scatter File
The scatter file is used in various processes, including:
- Firmware flashing: The scatter file helps tools like SP Flash Tool, Odin, or Fastboot to correctly flash firmware images onto the device.
- Device debugging: Developers and testers use scatter files to access and modify device partitions, facilitating debugging and development.
- Data recovery: In cases of data loss or corruption, a scatter file can help recovery tools to correctly identify and recover data from device partitions.
Conclusion
The MT6755 scatter file is a crucial file used in the flashing and debugging processes of Android devices with MediaTek MT6755 processors. It provides essential information about the device's storage and memory layout, allowing tools and developers to interact with the device's partitions.
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): mt6755 scatter file
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?

Quick reference table: Safe-to-modify vs Do-not-touch
| Category | Examples | Guidance | |---|---|---| | Typically safe | RECOVERY, BOOTIMG, SYSTEM, CACHE, USRDATA | Can be flashed for OS updates or custom ROMs | | High risk | PRELOADER, UBOOT, SEC_RO, PROTECT | Do not modify unless you have vendor-approved files and know the procedure | | Calibration/NVRAM | EFS, NVRAM, AP_CFG | Backup before touching — loss affects connectivity and IMEI |
