Understanding Scatter Files

A scatter.txt file is used by the SP Flash Tool, a popular tool for flashing ROMs, kernels, and other firmware components on MediaTek-based Android devices. This file contains information about the layout of the device's storage (like eMMC or NAND flash) and tells the SP Flash Tool where to place the various components of the firmware.

Why is This Important Today?

• Unbricking: If an MT6589 device (e.g., Micromax Canvas HD, Sony Xperia C, Lenovo P780) is soft-bricked, the scatter file is mandatory to restore via SP Flash Tool.
• Custom ROMs: Developers modifying partition sizes (e.g., resizing /system) must update the scatter file to match new eMMC boundaries.
• Data recovery: Forensic extraction of NVRAM or PRO_INFO partitions requires parsing the scatter file to know where to read from the eMMC raw dump.

Why “emmc” in the name?

Unlike older MediaTek chips that used raw NAND with FTL (Flash Translation Layer), the MT6589 uses eMMC, which has a built-in controller. The emmc in the filename indicates that addressing is linear (LBA – Logical Block Addressing) rather than page/block based. Understanding Scatter Files A scatter

2. Background: MT6589 and scatter files

• MT6589: a MediaTek SoC used in many Android phones (quad-core ARM Cortex-A7). Firmware flashing for MTK devices commonly uses scatter files.
• Scatter file role: a plain-text descriptor that lists partition names, start addresses, lengths, and storage type (e.g., emmc). SP Flash Tool reads it to map binary images to partitions.
