The MT6589 was MediaTek’s first native quad-core SoC (System on a Chip) with integrated 3G/HSPA+ modem. Key specs include: mt6589 android scatter emmc
From a flashing perspective, the MT6589 uses a proprietary preloader and DMA-based USB protocol (SP Flash Tool), which requires precise memory mapping.

Critical: Scatter files are chipset-specific and board-specific. An MT6589 scatter file for a Lenovo A820 will not work on a ZTE V987, even though both use MT6589. The partition sizes and preloader base address may differ. Search Google specifically for your device model +
The MT6589 is a system-on-a-chip (SoC) from MediaTek. Its key specifications include:
From a flashing perspective, the MT6589 uses a proprietary preloader and DA (Download Agent) protocol. This means you cannot simply copy a ROM to an SD card; instead, you must use tools like SP Flash Tool, which rely on a scatter file to understand the memory layout of the eMMC storage chip.
The scatter file for MT6589 differs from older MT6577 (NAND) versions. Here are the key technical features and partitions defined inside it: The MT6589 was MediaTek’s first native quad-core SoC
The eMMC chips paired with MT6589 are usually manufactured by Toshiba, Hynix, or SanDisk in capacities of 4GB, 8GB, or 16GB. By 2026, these chips are over a decade old and prone to failure modes like:
Mitigation: Always use Firmware Upgrade mode (not Format All) to minimize unnecessary erase cycles. Back up NVRAM and proinfo using MtkDroidTools while the device still powers on.
