8. Using with SP Flash Tool

1. Load the scatter file (Scatter-loading File button).
2. Check/uncheck partitions to flash.
3. Set Download Only (default) or Firmware Upgrade (wipes all).
4. Ensure preloader is only flashed when necessary – corrupting it requires EMMC pin shorting or JTAG recovery.

Method using ADB (root required)

adb shell
su
cat /proc/dumchar_info

This output includes partition names, start addresses, and sizes. Convert these values from hex to decimal and create your own scatter file.

7. Flashing Workflow Example (SP Flash Tool)

# 1. Load scatter file
SP_Flash_Tool -> "Scatter-loading" -> select MT6761_Android_scatter.txt
Example Modified Entry (Dynamic Partitions):
- partition_name: super
  file_name: super.img
  is_download: true
  type: 0
  linear_start_addr: 0x1B480000
  partition_size: 0x180000000
  region: EMMC_USER


2.2 Definition of Scatter File
A scatter file is a text-based configuration file (typically with a .txt extension but identified by tools as "scatter") that defines the physical and logical layout of the device’s non-volatile memory. It instructs the flashing software on:

Partition Name: (e.g., boot, system, userdata).
Physical Address: The specific memory offset where the partition resides.
Partition Size: The allocated size for the partition.
File Type: Whether the partition uses a raw image or a specific file system (EXT4, F2FS).

2. Select partitions
Check: preloader, lk, boot, recovery, system, vendor, userdata
1. Overview
The MT6761 (Helio A22) is a 12nm FinFET quad-core ARM Cortex-A53 processor from MediaTek, commonly found in budget smartphones, IoT devices, and tablets. A scatter file (or scatter-loading file) is a plain-text configuration file that describes the memory layout of the device’s flash storage (eMMC) – including partition names, addresses, sizes, and region types.
Scatter files are essential for:

Flashing firmware with tools like SP Flash Tool, SP Multi Port Download Tool, or fastboot.
Recovering bricked devices.
Extracting or repacking custom ROMs.
