Once you have downloaded the correct file, follow these steps to use it:
The chipset was a cornerstone of the affordable Android smartphone market, widely used in many dual-core devices around 2012–2014. For users looking to flash stock firmware, unbrick, or root these devices, understanding the MT6577 Android scatter EMMC.txt file is crucial.
| Scatter File (MT6577_Android_scatter.txt) | eMMC TXT (emmc.txt) | |--------------------------------------------|----------------------| | Logical partition map (software view) | Physical chip geometry (hardware view) | | Created from a working stock ROM | Dumped from a specific eMMC IC | | Contains partition names: preloader, uboot, boot, recovery, system, userdata | Contains CID, CSD, EXT_CSD registers | | Addresses are relative to user area | Addresses include boot partitions (0x0) |
Search for the specific device thread.
If you receive a "Storage type mismatch! scatter storage type is HW_STORAGE_EMMC target storage type is HW_STORAGE_NAND" error, your scatter file does not match your phone's hardware. You must locate the correct firmware or manually edit the scatter file using Notepad++ to change the storage type from EMMC to NAND . 2. BROM Error (e.g., 4032, 1013)
: Click on "To prepare blocks for Flash Tool." The utility will parse the internal partition table directly from the device's kernel map and generate a clean text file linked to your eMMC configuration.

chipset. This file is a map used by tools like SP Flash Tool to tell the software where to write specific image files (like boot, recovery, and system) on the device's internal memory.
Below is a comprehensive guide to understanding what this file does, how to obtain it, and how to use it safely. What is an Android Scatter File?
SP Flash Tool (Version 3.x or early 5.x optimized for legacy chips). Once you have downloaded the correct file, follow
- partition_index: SYS0 partition_name: PRELOADER file_name: preloader_mt6577.bin is_download: true type: SV5_BL_BIN linear_start_addr: 0x0 physical_start_addr: 0x0 partition_size: 0x40000 region: EMMC_BOOT_1 storage: HW_STORAGE_EMMC boundary_check: true is_reserved: false operation_type: BOOTLOADERS reserve: 0x00
Why? The new eMMC has a different (POWER_ON_WRITE) or a different Boot Area Size . The original scatter file expects 512KB boot partitions, but the emmc.txt from the new chip shows 2MB boot partitions. You must edit the scatter file’s boot_partsize or manually adjust the formatting.
Whether the phone is currently completely or stuck in a boot loop The version number of the SP Flash Tool you are using If you receive a "Storage type mismatch
If you only need a generic scatter file template to force SP Flash Tool to communicate with your device (for example, to read back the ROM or format a bricked block), you can download generic MediaTek scatter packs from developer forums:
The (MediaTek dual-core Cortex-A9) platform utilizes an eMMC (embedded MultiMediaCard) storage chip. Unlike older NAND chips, eMMC integrates the controller and flash memory. The scatter.txt file maps the logical addresses of the eMMC user partition to the firmware images.
