Mt6769 Scatter File May 2026

Technical Architecture & Analysis of the MT6769 Scatter File

Document Classification: Firmware Engineering / System-Level Configuration Target SoC: MediaTek MT6769 (Helio G80/G85 Platform) File Format: .scatter (MediaTek proprietary partition table definition)

Where to Download the Correct MT6769 Scatter File

You rarely download just the scatter file—it comes packaged inside the firmware.

2. Memory Topology & Syntax

The MT6769 utilizes a heterogeneous memory structure. The scatter file translates the SoC’s physical addressing requirements into logical partitions understandable by the flashing tool. mt6769 scatter file

Advanced: Editing an MT6769 Scatter File (For Developers)

Sometimes you need to resize a partition or add a new one (e.g., super partition for dynamic partitions). Here are the rules:

  1. All addresses must be sector-aligned (multiples of 0x200 or 512 bytes).
  2. Partitions must not overlap — use a hex calculator to ensure start_addr + size is ≤ next partition’s start address.
  3. Never change preloader’s start address unless you know the exact boot ROM mapping.
  4. After editing, recalculate checksums. SP Flash Tool expects an accompanying checksum.ini — you can regenerate with MTK_Checksum_Generator.exe.

Example: To increase vendor partition by 100MB: Technical Architecture & Analysis of the MT6769 Scatter

  • Old vendor start: 0x8c000000, size: 0x1E000000
  • New size: 0x1E000000 + 0x6400000 = 0x24400000
  • Shift the next partition’s start address accordingly.

Backup: Always Create Your Own Scatter File First

Before any flashing operation, generate a reference scatter file directly from your MT6769 device:

  1. Boot into BROM mode (hold volume up/down while plugging USB).
  2. Use MTK Meta Utility or MiFlash to read the GPT table.
  3. Save it as original_mt6769_scatter.txt.

This file is your lifeline. If a custom ROM flash corrupts the partition table, you can restore it using SP Flash Tool’s “Format” + “Download” with your backup. All addresses must be sector-aligned (multiples of 0x200

MT6769 Scatter File vs. MT6765 / MT6785 – Key Differences

| Feature | MT6769 Scatter | MT6765 (Helio P35) | MT6785 (Helio G90) | | --- | --- | --- | --- | | Partition count | 47–52 | 38–42 | 58–64 | | Dynamic partitions | Supported (super.img) | Rarely | Yes | | A/B slot support | Some variants (e.g., Realme) | No | Yes | | Typical preloader block | 0x0 – 0x400000 | 0x0 – 0x300000 | 0x0 – 0x800000 | | tee partition | Yes (TrustZone) | No | Yes |

Always verify your chipset: boot into BROM mode (hold volume up/down while connecting USB) and use mtk printgpt – it will reveal the exact chip ID (0x6769 for Helio G70/G80/G85).
