Mt6768-android-scatter.txt Review
| Item | What’s expected |
|------|----------------|
| preloader | Exists, size ~4MB, region EMMC_BOOT_1 |
| pgpt (partition table) | Should be at 0x0 on user area |
| boot1 / boot2 | Separate from Android partitions |
| tee / trustzone | Should be present (security) |
| vbmeta | Must exist if using Verified Boot |
| super (dynamic partitions) | For Android 10+ (MT6768 often uses it) |
| userdata | Large size, region EMMC_USER |
| cache | May be small or absent (moved to /data) |
To prepare a technical document or "paper" for an MT6768 Android Scatter file, you need to structure it as a firmware configuration reference. This file serves as a blueprint for the MediaTek (MTK) Smart Phone Flash Tool (SP Flash Tool), defining how memory is partitioned on devices using the Helio G80/G85 (MT6768) chipset. 1. Executive Summary
The mt6768-android-scatter.txt is a structured map of the device's internal eMMC or UFS storage. It specifies the exact start addresses and physical lengths for every partition required to boot the Android OS, including the preloader, recovery, and system images. 2. Platform Technical Specifications Platform MT6768 (MediaTek Helio G80/G85) Storage Type EMMC / UFS Config Version Typically V1.1.2 or V1.1.8 Project Code Often identified by project IDs like p325a or merlin 3. Core Partition Layout
A standard MT6768 scatter file contains approximately 22 to 27 partitions. Key partitions to document include:

- partition_index: 0
partition_name: preloader
file_name: preloader_mt6768.bin
is_download: true
type: SV5_BL_BIN
linear_start_addr: 0x0
physical_start_addr: 0x0
partition_size: 0x400000
region: EMMC_BOOT_1
Advanced users sometimes need to modify the scatter file. Never change it arbitrarily unless you know the exact memory map.
The exact content of a mt6768-android-scatter.txt file can vary depending on the device model, its specifications, and the customizations made by the device manufacturer or the community. Always use a scatter file that is specifically designed for your device to avoid potential issues during the flashing process. mt6768-android-scatter.txt
The mt6768-android-scatter.txt file is a critical configuration document used for flashing and managing firmware on devices powered by the MediaTek MT6768 (Helio G80/G85) chipset. It acts as a map for the device's storage (typically eMMC), telling flashing tools like SP Flash Tool exactly where each component of the Android OS should be written. Core Components of the Scatter File
The file contains a detailed list of partitions (usually between 22 and 24). Key technical attributes defined for each include:
Partition Name: Identifies the block (e.g., preloader, boot, system, userdata).
Linear Start Address: The physical starting point on the storage chip (e.g., 0x0 for the preloader).
Physical Read/Write Size: The exact hexadecimal size allocated to that partition.
Operation Type: Defines if the partition is a standard image (NORMAL_ROM) or a specific file system (EXT4_IMG). | Item | What’s expected | |------|----------------| |
Download/Upgrade Status: A boolean setting (True/False) that tells the flashing tool whether to overwrite this partition during a standard "Download" or "Firmware Upgrade" session. Critical Partitions in MT6768 Partition Name Primary Function Significance preloader Initial boot stage
Most critical; if corrupted, the device won't communicate with the PC. vbmeta Verified Boot Metadata
Essential for Android's security handshake; tampering often requires a custom vbmeta. recovery Maintenance UI
Stores the recovery environment (Stock or Custom like TWRP). userdata User Files/Apps
Typically the largest partition, ranging from 0.8GB to over 4GB depending on the device model. metadata Encryption Data Stores keys and data related to file-based encryption. Usage Scenarios
Unbricking: Using a MT6768 scatter file to re-flash a device that won't boot. To prepare a technical document or "paper" for
Custom ROMs: Modifying the scatter file to expand certain partitions (like system) to accommodate larger custom firmwares.
Backups: Tools use this map to "read back" individual partitions from a working device to create a firmware backup.
Caution: Using a scatter file from a different device model (even if it uses the same MT6768 chip) can permanently "brick" your hardware due to differences in partition sizes and memory addresses.
Do you need help locating a specific version of this file for a particular device model, or are you trying to fix a flashing error?

Here is a practical guide to using mt6768-android-scatter.txt with SP Flash Tool v5.x:
If you see ERROR: STATUS_EXT_RAM_EXCEPTION, your scatter file’s preloader address is incorrect for that specific MT6768 variant.
In a typical mt6768-android-scatter.txt, you will find these key partitions:
