Mt8167 Scatter File Top

Demystifying the MT8167: A Guide to the Scatter File Structure

If you are reading this, you are likely staring at a flashing tool (like SP Flash Tool) and a folder full of cryptic files. You might be trying to unbrick a tablet, port a custom ROM, or simply understand how your device ticks.

At the heart of every MediaTek firmware modification lies the Scatter File. For devices running the popular MT8167 chipset (often found in mid-range Android tablets and automotive head units), understanding this file is the difference between a successful flash and a expensive paperweight.

In this post, we are going to the "top" of the MT8167 scatter file structure. We will break down what it is, how to read it, and the critical partitions you need to know. mt8167 scatter file top

Common Use Cases for MT8167 Scatter Files

Anatomy of an MT8167 Scatter File: Top Section Breakdown

Let’s examine a real-world example of the top section from a typical MT8167_Android_scatter.txt file. Open the file in any text editor (Notepad++, Sublime, or even basic Windows Notepad). The first few non-comment lines look like this:

# General config
PRELOADER 0x0
MBR 0x0
EBR1 0x0
PMT 0x0
PRO_INFO 0x0
# Other settings follow...

However, a modern, properly formatted scatter file for MT8167 (used with SP Flash Tool v5.x and above) has a more structured top: Demystifying the MT8167: A Guide to the Scatter

Let’s break each element down:

7. emmc_boot: 0x4000000

This is one of the most dangerous values in the "top" section. It reserves 64 Megabytes (0x4000000 in hex) for the eMMC boot partitions (Boot Area 1 & 2). If you modify this, the tool will offset all subsequent partitions incorrectly. However, a modern, properly formatted scatter file for

Common Scenarios with the MT8167 and TOP

Best Practices for Editing the Scatter File Top

  1. Always keep a backup of the original scatter file before editing.
  2. Only modify the top section if you understand the storage hardware. Changing block_size is almost never required.
  3. Use consistent line endings (Linux LF, not Windows CRLF) to avoid parsing oddities.
  4. Validate with a checksum – Some SP Flash Tool versions ignore malformed lines silently, leading to subtle bricking.

For MT8167 specifically, many Chinese tablet manufacturers ship scatter files with a project name that includes spaces (e.g., MT8167_10.1_INCH). Remove spaces if you encounter tool errors.

Scenario A: The "No Space Left" Error

You try to flash a custom recovery, and SP Flash Tool throws S_DL_PMT_ERR_NO_SPACE (0x1313). Root cause: The "top" settings describing total flash size conflict with the partition table. Specifically, the sum of all partition sizes (from the bottom) exceeds the limit implied by the storage settings in the top.

Error 1: “Storage type mismatch”

Symptom: SP Flash Tool throws ERROR: S_STORAGE_TYPE_MISMATCH (0x1A05) Cause: The scatter file top says storage: NAND, but the device has eMMC (or vice versa). Fix: Edit the scatter file top to match your device. If unsure, open the device’s stock scatter file (extracted via MTK Droid Tools or readback) and copy the storage type line.
