Mt6589 Android Scatter Emmc

To produce a scatter file for a device using the MT6589 chipset eMMC storage

, you can use specialized tools that read the partition map directly from your phone. This file is essential for flashing firmware or individual partitions (like recovery) using SP Flash Tool Recommended Method: MTK Droid Tools The most common way to generate this file is through MTK Droid Tools Preparation USB Debugging

on your phone (Settings > About Phone > Tap 'Build Number' 7 times, then find 'Developer Options'). Connection : Connect your device to your PC and launch MTK Droid Tools Map Partitions : Once the tool recognizes your device info, click on the Blocks Map : In the new window, click Create Scatter File . Choose your save location and name it (typically MT6589_Android_scatter_emmc.txt What is in an eMMC Scatter File? mt6589 android scatter emmc

A scatter file is a text-based map that tells flashing tools exactly where each piece of software (like the bootloader or system image) belongs in the device's physical memory. Arm Developer eMMC Specifics

: Unlike older NAND storage, eMMC scatter files often reference specific regions such as EMMC_BOOT_1 : It includes the partition name linear start address of each block. rigacci.org Alternative: WWR MTK Tool To produce a scatter file for a device

If MTK Droid Tools does not support your specific Android version, the WWR MTK Tool

is a modern alternative. It can create a scatter file by analyzing a "readback" (a full backup of your phone's memory) created via SP Flash Tool. Key Resources For a deep dive into Android partitions on MTK devices, Rigacci.org provides a technical breakdown of eMMC regions. Detailed guides on using these files for software downloads can be found on Are you trying to fix a bricked device or just create a of your current firmware? Android Partitions on MTK Devices - rigacci.org Verbose/debug mode with hex dumps Dry-run mode (simulate

🖥️ CLI / UI Features

• Verbose/debug mode with hex dumps
• Dry-run mode (simulate without writing)
• Progress bar for large partitions
• Scriptable via JSON/YAML configs
• Output in machine-readable formats (JSON, CSV)

Method A: From a ROM Backup (Best)

If you previously backed up your phone using MTK Droid Tools (a famous tool for legacy MTK devices), you will find a MT6589_Android_scatter_emmc.txt file in the backup folder. This is the safest file to use.

Typical partition entries in MT6589 (eMMC) scatter files

Common partition names you’ll see:

• preloader
• lk or u-boot (bootloader)
• recovery
• boot
• system
• cache
• userdata
• persistent / persist
• nvram
• sec_ro / factory
• tee or trustzone (for secure partitions) Each entry includes fields like:
• partition_index
• partition_name
• file_name (local image file the tool uses/writes)
• is_download (1/0)
• type (e.g., EMMC, UFS)
• linear_start_addr (byte offset)
• partition_size (bytes or 0x to indicate full remaining)
• region (if applicable)

What is the MT6589?

The MT6589 was MediaTek’s first native quad-core SoC (System on a Chip) with integrated 3G/HSPA+ modem. Key specs include:

• CPU: 1.2 GHz quad-core Cortex-A7
• GPU: PowerVR SGX 544MP (286 MHz)
• Memory: 32-bit LPDDR2 up to 533 MHz
• Storage Interface: eMMC 4.5

From a flashing perspective, the MT6589 uses a proprietary preloader and DMA-based USB protocol (SP Flash Tool), which requires precise memory mapping.

9. Device Detection

• Auto-detect MT6589 via USB VID/PID (MediaTek Preloader/BROM)
• Identify eMMC CID, CSD, and capacity
• Detect current boot partition active

Step 5: Execute Flashing

• Click Download.
• Now power off the device completely (remove battery if removable).
• Connect USB. SP Flash Tool should detect the phone in preloader mode and start flashing.
• Progress bar fills → Green checkmark indicates success.

⚙️ MT6589 Specifics

• Support for eMMC 4.5 (typical on MT6589)
• Handle DDR mode timing if applicable
• Respect boot partitions for preloader/uboot
• Compatibility with SP Flash Tool scatter format v1.0
