A typical MT6769 scatter file looks intimidating, but once you understand the sections, it becomes logical. Here is a concrete example of how a real-world entry appears:
- partition_index: SYS23
partition_name: system
file_name: system.img
is_download: true
type: EXT4_IMG
linear_start_addr: 0x4a800000
physical_start_addr: 0x4a800000
partition_size: 0x60000000
region: EMMC_USER
Let us break down each critical field:
In the world of Android firmware modification, few files are as critical yet misunderstood as the scatter file. For devices powered by MediaTek chipsets—particularly the popular mid-range MT6769 (also known as the Helio G70/G80/G85)—this file is the master key to the device’s storage architecture. mt6769 scatter file
If you have ever tried to flash stock firmware, unbrick a dead device, or manually partition an MT6769 handset (such as the Redmi 9, Redmi 9T, Realme C15, or Tecno Camon series), you have likely encountered the MT6769_Android_scatter.txt file. This article will dissect everything you need to know: what it is, its internal structure, how to use it with SP Flash Tool, common errors, and advanced tips.
While scatter files exist for all MediaTek SoCs (MT6580, MT6739, MT6771, etc.), the MT6769 version has distinct characteristics: A typical MT6769 scatter file looks intimidating, but
Before any flashing operation, generate a reference scatter file directly from your MT6769 device:
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. Let us break down each critical field: In
If you have a working MT6769 device (rooted), you can generate the scatter file live:
adb shell
su
cat /proc/dumchar_info
This outputs the exact addresses and sizes. Compare it to a stock scatter file to detect hidden partitions like protect1, protect2, or nvram.
Alternatively, use Wwr_MTK (MediaTek Write Tool) to parse a boot.img or recovery.img and reconstruct the scatter file.
