Guide: MT6761 scatter file — what it is, how to use it, and practical tips What the MT6761 scatter file is
The scatter file is a plain-text map used by MediaTek flashing tools (e.g., SP Flash Tool) that describes memory layout: partition names, start addresses, lengths, and where firmware images should be loaded for MediaTek SoCs. MT6761 (a MediaTek Helio A22 variant) uses the same scatter-driven flashing workflow as other MediaTek chips.
When you need it
Creating or customizing firmware images (ROMs, recoveries). Flashing or repartitioning a device with SP Flash Tool or similar. Extracting partitions from a dumped full firmware or for backup/restore. Porting ROMs or building scatter-based OTA packages. mt6761 scatter file
Typical scatter file structure (key entries)
File is UTF-8, usually named like scatter.txt or MT6761_Android_scatter.txt. Header lines: general meta, then a list of partition entries. Each partition block includes:
partition_index: integer index partition_name: e.g., preloader, mbr, ebr1, lk, boot, recovery, system, cache, userdata, etc. file_name: binary image file to load (or NONE) is_download: 1 or 0 (whether tool should flash it) type: e.g., NORMAL, SECURE_RO, etc. linear_start_addr: hex or decimal start address (device flash offset) partition_size: hex or decimal length physical_start_addr: typically same as linear_start_addr Guide: MT6761 scatter file — what it is,
Example entry (conceptual) - partition_index: 0 partition_name: preloader file_name: preloader_xxx.bin is_download: 1 type: RAW linear_start_addr: 0x0 partition_size: 0x40000 physical_start_addr: 0x0
How to obtain a correct scatter file
From stock firmware packages: official or dumped ROMs usually include a scatter file. Extract from a device dump using tools like MTK Droid Tools, or dd from a rooted device, then generate scatter via tooling that can map partition table. From ROM builders or device-specific development communities (XDA, GitHub repos). Verify compatibility with your exact MT6761 device model and eMMC/UFS configuration.

Using the scatter file with SP Flash Tool
Launch SP Flash Tool and load the scatter file (Download tab -> Choose). The tool lists partitions and associated files. Confirm file paths for partitions you want to flash. Select appropriate download mode:
