The scatter file acts as a map for the SP Flash Tool. It tells the software exactly where each component of the Android OS (the bootloader, recovery, system partition, etc.) should be written on the device's physical internal memory.
SP Flash Tool provides three distinct operation modes. Selecting the wrong one can permanently delete system configurations.
| Partition Name | Short Description | Why It's Critical | | :--- | :--- | :--- | | PRELOADER | The very first piece of code the processor executes. | Initializes hardware like the DRAM and eMMC controller. Flashing a corrupted preloader will brick your device. | | MBR | Master Boot Record | Contains the primary partition table for the device. | | EBR1 / EBR2 | Extended Boot Records | Used to create logical partitions that extend beyond the MBR's limitations, often for /data and internal SD storage. | | UBOOT | U-Boot Bootloader | The second-stage bootloader. Its main job is to initialize the display and then load the BOOTIMG or RECOVERY kernel. | | BOOTIMG | Android Boot Image | Contains the Linux kernel and the initial RAM disk (initramfs), which is essential for booting the main Android OS. | | RECOVERY | Recovery Image | A minimal Linux environment used for system maintenance, factory resets, and installing official system updates. | | ANDROID | System Image | Usually contains the read-only system partition, which holds the Android framework, system apps, and libraries. | | CACHE | Cache Partition | Stores temporary system data and OTA update files. Can be safely wiped without data loss. | | USRDATA | User Data Partition | Where all your installed apps, settings, and personal files (like photos and downloads) are stored. Wiping this performs a "factory reset". |
: Holds the stock or custom recovery environment (like TWRP or CWM).
To help find the exact tool version or firmware bundle for your device, tell me: The scatter file acts as a map for the SP Flash Tool
The absolute hexadecimal starting coordinate on the eMMC chip where the specific partition begins.
Confirms the hardware target (e.g., platform: MT6589 ).
The tool will automatically populate the list with checkmarks next to each partition image.
Install the correct MediaTek USB VCOM drivers onto your Windows PC. Selecting the wrong one can permanently delete system
: The safest option. It updates or overwrites selected partitions without altering the overall partition layout or wiping unique calibration data like NVRAM. Use this for basic upgrades or unbricking.
It allows technicians and advanced users to flash their devices with custom ROMs, updates, or fixes. By specifying the exact memory locations for different parts of the software, it ensures that the flashing process is carried out correctly and safely.
: Verify your phone model. Download the correct firmware package explicitly designed for your exact device SoC. 3. PMT changed for the ROM; it must be downloaded
If you need help resolving a specific error or structural issue with your device, please let me know: Flashing a corrupted preloader will brick your device
On MT6589, eMMC blocks are typically 512 bytes. The scatter file's linear_start_addr must be (multiple of 512). For example:
The specific reference to "MT6589 Android scatter emmc.txt" implies a configuration file designed for devices powered by the MT6589 processor and equipped with eMMC (embedded MultiMediaCard) storage. eMMC is a type of non-volatile storage that is widely used in mobile devices due to its compact size, performance, and reliability.
: Do not unplug the USB cable while the tool is writing data.
