If you are dealing with legacy firmware, brick recovery, or custom ROM development for an MT6589 device, you will inevitably encounter a file named (often shortened by tools like SP Flash Tool, Miracle Box, or SP Multi-Port Download Tool).
As of 2026, MT6589 devices are considered legacy, but they remain excellent learning tools for Android low-level engineering. Treat your scatter file like a treasure map – one wrong coordinate, and you may never boot again. But with caution and the right backup, you can breathe new life into old hardware. If you are dealing with legacy firmware, brick
Part_Name Size StartAddr Type preloader 0x40000 0x0 2 dsp_bl 0x40000 0x40000 2 ... Convert StartAddr from decimal (if shown) to hex, and Size from bytes to hex. That gives you a raw scatter mapping. But with caution and the right backup, you
ANDROID 0x3a80000 # start remains same CACHE 0x25a80000 # old: 0x1aa80000 → moved forward USRDATA 0x3aa80000 # old: 0x29a80000 → moved forward This is and requires a custom recovery that supports the new partition layout. 7. Extracting the Scatter File from an MT6589 Device (Without Firmware) If you have a working MT6589 device but lost firmware, you can pull the scatter info from /proc/dumchar_info (if present) or use parted on eMMC: That gives you a raw scatter mapping
This article dissects every aspect of this scatter file, its structure, its critical role in eMMC partitioning, and how to safely use it in 2025–2026 for data recovery or system restoration. A scatter file is a plain-text configuration file that describes the memory map of an Android device based on MediaTek (or similar) chipsets. It tells flashing software exactly where to write each firmware component on the eMMC (embedded MultiMediaCard) storage chip.
