partition_index: 1 partition_name: pgpt file_name: NONE is_download: false type: NORMAL_ROM linear_start_addr: 0x0 physical_start_addr: 0x0 partition_size: 0x80000 region: EMMC_USER
To obtain a factory-correct scatter file:
A red bar will appear first (DA download), followed by a yellow bar showing the flashing progress.
: 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. mt6761 scatter file
The hardware location on the storage chip.
Last updated: 2025 – Compatible with SP Flash Tool v5.2124 and newer.
Use a tool like (open-source) or Miracle Box to read the partition structure. Last updated: 2025 – Compatible with SP Flash Tool v5
| Partition Name | File Name Example | Size (Approx.) | Function | | :--- | :--- | :--- | :--- | | | preloader_mt6761.bin | 2 MB | The first code executed by the CPU. Initializes DRAM and loads the next bootloader. | | PGPT | pgpt.img | 8 KB | The Primary GPT (GUID Partition Table). Contains the primary partition table structure. | | SD_GPT | sd_gpt.img | 8 KB | A backup of the GPT. It's a critical redundancy feature for partition table integrity. | | PRO_INFO | pro_info.img | 15 MB | Stores product-specific information, including the device's serial number (SN). | | NVRAM | nvram.img | 5 MB | A vital partition containing device-unique data like the IMEI numbers, Wi-Fi/BT MAC addresses, and calibration data . | | BOOTIMG | boot.img | 32 MB | Contains the Linux kernel and a basic ramdisk. The heart of the Android boot process. | | RECOVERY | recovery.img | 32 MB | A minimal environment used for factory resets, OTA updates, and booting custom software like TWRP. | | LOGO | logo.bin | 8 MB | Holds the boot logo image displayed during the initial startup. | | SYSTEM | system.img | ~2.5 GB+ | The largest partition. Contains the Android OS framework, system apps, and core libraries. | | CACHE | cache.img | 200 MB+ | A temporary storage area for system data, app caches, and OTA update files. Often wiped during updates. | | USERDATA | userdata.img | Rest of space | The data partition. Holds all user-installed apps, settings, photos, and files. | | SECCFG | seccfg.img | 1 MB | Stores security-related configurations, including the state of the bootloader lock. | | VENDOR | vendor.img | 400 MB+ | Contains device/vendor-specific proprietary libraries, drivers, and binaries (OEM customizations). | | PROTECT1 / PROTECT2 | protect1.img | 25 MB | Partitions for security-related operations, often storing encryption keys and metadata. |
The is a text-based configuration file used by MediaTek's SP Flash Tool to communicate with devices powered by the MT6761 chipset (often found in budget smartphones like the Helio A22). It acts as a map, defining exactly where partitions (like boot , recovery , and system ) are located on the device's storage. Core Components of a Scatter File A standard MT6761 scatter file contains:
- partition_index: 8 partition_name: expdb file_name: NONE is_download: false type: NORMAL_ROM linear_start_addr: 0x2a80000 physical_start_addr: 0x2a80000 partition_size: 0xa00000 region: EMMC_USER Initializes DRAM and loads the next bootloader
Without this file, flashing tools cannot identify the correct memory regions to write data to. It is essential for: YouTube·Hovatekhttps://www.youtube.com
