A scatter file (usually named MT6761_Android_scatter.txt) is a partition layout table. It tells tools like SP Flash Tool, Odin (for MediaTek), or MiFlash exactly where to write data on the eMMC/UFS chip.
It defines:
Without a correct scatter file for the MT6761, you risk overwriting critical bootloaders (preloader, LK) or bricking the device permanently.
The MT6761 is a 12nm quad-core ARM Cortex-A53 SoC. A scatter file is essential for tools like SP Flash Tool, fastboot, and custom flashing utilities. The previous scatter file was outdated, causing partition overlap and flash write failures. This new version corrects partition boundaries and adds reserved regions required by the latest bootloader and trust zone firmware.
| Item | Previous Version | New Version | Reason |
|----------------------|---------------------------|-------------------------|------------------------------------------|
| Preloader start | 0x8000 (incorrect offset) | 0x0 | Align with boot ROM mapping |
| Tee1 / Tee2 size | 0x200000 each | 0x500000 each | TrustZone firmware size increased |
| Reserved region after para | Not present | 0x100000 zero-filled | Prevent overflow into logo partition |
| Metadata partition | Missing | 0x2000000 (32 MiB) | Required for dynamic partitioning (Android 10+) |
If you have a corrupted scatter file but know the partition layout (from a firmware dump or dmesg), you can edit the linear_start_addr and partition_size values in this text file to match your specific hardware.
Understanding and Downloading the MT6761 Scatter File If you are looking to unbrick your device, upgrade its firmware, or perform a low-level memory dump, finding the correct MT6761 scatter file (new) is the most critical step [2]. The MT6761, commercially known as the MediaTek Helio A22, powers many budget-friendly smartphones from brands like Tecno, Infinix, Xiaomi, and Samsung [3, 4].
This article covers everything you need to know about the scatter file, where to find the latest versions, and how to use them safely. What is an MT6761 Scatter File?
A scatter file is a simple text document (.txt) used by MediaTek flashing tools (like SP Flash Tool) to understand the partition structure of a device's NAND or eMMC flash memory [2].
The "new" versions of these files often include updated partition maps for devices running Android 10, 11, or 12, which may have different security offsets or partition sizes compared to older legacy models [5]. Why You Need the "New" Version
Using an outdated or incorrect scatter file can lead to several issues: BROM Errors: The tool won't communicate with the device.
PMT Changed: A common error in SP Flash Tool indicating the partition table on the phone doesn't match the scatter file [2].
Hard Brick: Writing data to the wrong memory address can permanently disable the device. How to Use the MT6761 Scatter File mt6761 scatter file new
To flash your Helio A22 device, follow these standard steps:
Download the Firmware: Always try to find the full "Fastboot" or "Flash File" for your specific model. The scatter file is usually located in the Images or Firmware folder.
Install VCOM Drivers: MediaTek devices require specific Preloader/VCOM drivers to be recognized by a PC in "Connection Mode" [5]. Open SP Flash Tool: Click on "Choose" next to the Scatter-loading File field. Select your MT6761_Android_scatter.txt.
Bypass Authentication: Most new MT6761 devices have SLA/DA authentication. You may need an "MTK Auth Bypass Tool" to disable this security before the SP Flash Tool can write to the memory [4, 5]. Common MT6761 Devices
You will typically search for this scatter file if you own one of the following: Xiaomi: Redmi 6A, Redmi A1/A2 Samsung: Galaxy A03 Core, Galaxy M01 Core Tecno: Spark 4, Spark 8, Camon 12 Air Infinix: Hot 8 Lite, Smart 5/6 Safety Tips
Backup NVRAM: The scatter file defines the NVRAM partition, which holds your IMEI and network data. Never format this partition unless you have a backup [2, 5].
Match the Build Number: Ensure the firmware version matches your device's region (e.g., Global, Indian, or European) to avoid "System Checked Fail" errors.
Where to download?Reliable sources for the latest MT6761 scatter files include Hovatek, GSM Forum, and RepairMyMobile. Always scan downloaded .txt files for malicious scripts before use.
A MT6761 scatter file is a critical text-based configuration file (.txt) used by flashing tools like SP Flash Tool to map the partition structure of a MediaTek device. For the MT6761 chipset (commonly found in budget-friendly smartphones), a "new" or updated scatter file is essential for modern flashing tasks such as installing stock firmware, bypassing FRP locks, or flashing custom recoveries like TWRP. What is the MT6761 Scatter File?
Think of the scatter file as a blue print or map. It contains specific memory addresses and partition names (like preloader, boot, system, and recovery) that tell the flashing software exactly where to write each file in the firmware package.
Structure: Typically named MT6761_Android_scatter.txt, it defines roughly 22 to 24 partitions for devices using eMMC storage.
Key Attributes: Each entry includes the partition_name, linear_start_addr, physical_start_addr, and partition_size. How to Get the New MT6761 Scatter File A scatter file (usually named MT6761_Android_scatter
There are three primary ways to acquire a new scatter file for your device: 1. Extract from Stock Firmware
The most reliable way is to download the Stock ROM for your specific device model. The scatter file is almost always included in the main directory of the extracted firmware folder.
Source: Search for your device's official vendor website or reputable firmware databases like AndroidMTK. 2. Create Your Own (Using Wwr_MTK)
If you cannot find a firmware package, you can generate a scatter file directly from a working device. Tools: Use Wwr_MTK in conjunction with SP Flash Tool.
Process: This involves performing a "ROM dump" (reading the device's existing partition table) and then using Wwr_MTK to parse that data into a new scatter format. 3. Online Repositories
Community forums like XDA Developers or Hovatek often host scatter files shared by other users for specific MT6761 models. How to Use the Scatter File for Flashing
Once you have the file, follow these steps to use it with SP Flash Tool:
Launch SP Flash Tool: Open the application and navigate to the Download tab.
Load Scatter: Click the "Choose" button next to Scatter-loading File and select your MT6761_Android_scatter.txt.
Verify Partitions: The tool will automatically populate the list of partitions. Ensure the files you want to flash are correctly linked.
Select Mode: Use "Download Only" for standard updates to avoid losing critical data like IMEI (avoid "Format All + Download" unless absolutely necessary).
Connect Device: Click Download, power off your phone, and connect it to your PC while holding the Volume Up or Volume Down buttons (BROM mode). Important Safety Tips Without a correct scatter file for the MT6761,
Model Matching: Never use a scatter file from a different model or variant. Doing so can cause a bootloop or permanently "brick" the device.
Backup First: Always back up your current firmware and user data before attempting any flashing process.
Drivers: Ensure you have the correct MediaTek VCOM Drivers installed so your computer can recognize the phone in flash mode.

No. Although both are Helio A series, MT6762 (Helio P22) has a different memory mapping and additional cores. Flashing will corrupt the preloader.
