[Revised] How to use SP Flash tool to flash Mediatek firmware mt6761 scatter file
MT6761 scatter file is a critical configuration file used in the Android ecosystem, specifically for devices running on the MediaTek Helio A22
chipset. It serves as a structural map that guides flashing software, such as the SP Flash Tool, on where to write specific data within the device's storage. Purpose and Function
At its core, the scatter file is a text-based document (usually ) that describes the partition layout
of the phone’s NAND or eMMC memory. It contains the start addresses, lengths, and names of every partition—such as the bootloader, recovery, system, and user data. Without this map, a flashing tool would have no way of knowing where the "System" partition ends and "User Data" begins, leading to a bricked device. Key Components
A typical MT6761 scatter file includes several vital parameters for each partition: Partition_Name: Identifies the section (e.g., Linear_Start_Addr: The exact hex address where the data begins. Physical_Start_Addr: The location on the hardware level. Is_Download:
A boolean flag (true/false) indicating if the partition should be updated during a standard flash. Importance in Development and Repair
The MT6761 scatter file is indispensable for two main groups: Firmware Developers:
Those creating custom ROMs or porting recoveries (like TWRP) use the scatter file to ensure their custom images are written to the correct memory blocks. Repair Technicians:
When a device is "bootlooped" or software-bricked, technicians use the scatter file to perform a "Firmware Upgrade" or "Format All + Download," which resets the memory structure to factory defaults. Conclusion
An MT6761 scatter file is a text-based configuration file (usually named MT6761_Android_scatter.txt) used by the SP Flash Tool to map out the partition structure of a MediaTek Helio A22 device's eMMC storage. Key Characteristics The MT6761 scatter file is a configuration text
Platform Identification: It contains headers that identify the platform (e.g., MTK_PLATFORM_CFG) and the specific chip ID (MT6761).
Partition Mapping: It defines the linear and physical start addresses for essential partitions such as the preloader, boot, recovery, system, and userdata.
Flash Control: The file tells the flashing software which binary files correspond to which partition and whether they should be upgraded or wiped. Typical Structure
A standard MT6761 scatter file includes about 22 to 24 partitions. Each entry looks similar to this: Partition Name: (e.g., recovery) Linear Start Address: (e.g., 0x8000000) Physical Start Address: (e.g., 0x8000000) Partition Size: (e.g., 0x2000000)
Is Downloadable: Determines if the flash tool will attempt to write a file to this section. Where to Get One
Firmware Packages: The scatter file is always included in the official Stock ROM or Firmware for your specific device model.
Creation Tools: If you cannot find one for your specific device, you can use WWR MTK or similar tools to extract and create a scatter file from a working device backup.
Reference Repositories: Sites like Scribd or community forums like Hovatek often host verified versions for common models.
Note: Never use a scatter file from a different processor or a significantly different phone model, as this can hard-brick your device by writing data to the wrong memory addresses. To provide the exact file or guide, could you tell me:

MT6761 scatter file is a plain text configuration file ( ) used by MediaTek-powered devices to define the precise layout of the phone's internal eMMC or UFS storage. It serves as a roadmap for flashing tools, such as the SP Flash Tool
, indicating exactly where each piece of firmware (like the bootloader or system image) should be written in the memory. rigacci.org Core Structure of the File
The MT6761 scatter file typically identifies between 22 to 24 partitions. Each partition entry includes several key attributes: Partition Name : The identifier for the section (e.g., Linear/Physical Start Address
: The exact hexadecimal location in the memory where the partition begins. Partition Size : The allocated space for that specific component. : The corresponding binary or image file (e.g., ) that should be flashed into that partition. Is_Download : A boolean flag (
) determining if the partition is part of a standard firmware update. MT6761 Android Scatter Configuration | PDF - Scribd
Risks and precautions
- Bricking risk: Writing incorrect binaries or wrong scatter files can brick the device—especially overwriting PRELOADER or partition table.
- IMEI loss: Overwriting NVRAM without backup can erase IMEI and radio calibration; restoring requires correct backups and sometimes proprietary tools.
- Device variants: MT6761 is used across many models with different flash layouts; use a scatter file specific to the exact device model and storage configuration.
- Secure boot and signed images: Some devices implement secure boot or signature checks; arbitrary images may be rejected or cause boot loops.
- Backups: Always backup NAND/EMMC, at least NVRAM and partition table, before flashing.
Usage Protocols
Sample MT6761 Scatter File Structure
Below is a generic representation of how an MT6761 scatter file defines a partition (e.g., the boot partition).
[partition_index]
# 1 is typically preloader, assuming this is index 8
partition_name = boot
file_name = boot.img
is_download = true
type = NORMAL
linear_start_addr = 0x8000000
physical_start_addr = 0x8000000
partition_size = 0x2000000
linear_start_addr: Where the partition begins on the chip.partition_size: The allocated size (e.g., 0x2000000 is roughly 32MB).
Issue 2: Scatter file missing after download
Cause: Some websites strip scatter files to reduce ZIP size. Solution: Download complete firmware packages. Look for "Full ROM" or "Factory Firmware". Do not use "OTA update" ZIPs – they lack scatter files.
Step-by-Step Flashing Process
- Disable Driver Signature (Windows 10/11 – requires advanced boot).
- Extract the official firmware package. Inside, you will find:
MT6761_Android_scatter.txtpreloader_mt6761.binboot.img,recovery.img,system.img, etc.
- Launch SP Flash Tool (v5.20 or newer).
- Click Scatter-loading and select your
MT6761_Android_scatter.txt. - Verify the partitions. By default, all partitions are checked for download. For standard unbricking, keep them all checked. For safety (retaining user data), uncheck
userdataandcache. - Choose Download Only (safe) or Firmware Upgrade (completely overwrites partition tables).
- Click the Download button.
- Power off your MT6761 device completely.
- Connect the USB cable. The tool will detect the device in BROM mode and begin flashing.

7. Common Modifications & Cautions
| Modification | Risk Level | Notes |
|-----------------------------|------------|-----------------------------------------------------------------------|
| Changing partition size | High | Can brick device; requires matching GPT and kernel cmdline. |
| Adding a new partition | High | Must update GPT and ensure bootloader doesn’t overwrite. |
| Disabling preloader download | Medium | Prevents accidental preloader corruption, but flashing fails if preloader changes. |
| Editing linear_start_addr | Critical| Overlaps cause data loss or hard brick. |
⚠️ Always back up the full flash (including boot1/boot2) before editing a scatter file.
