Have you successfully used a hot scatter file on an MT6769 device? Share your experience (and the exact test point locations) in the comments below!
To create or obtain a scatter file for an device (such as those using Helio G80/G85), you can use several methods depending on whether you have the physical device or just its firmware. A scatter file acts as a map for the SP Flash Tool , detailing the partition layout of your device's memory. Method 1: Extracting from Firmware (Recommended)
If you already have the official stock ROM or firmware for your MT6769 device, the scatter file is typically included in the firmware folder. Search for : Look for a text file named MT6769_Android_scatter.txt within your extracted firmware folder. Verification
: Open the file with a text editor like Notepad++ to ensure it lists partitions such as Method 2: Generating via WWR MTK Tool mt6769 scatter file hot
If you do not have the scatter file but can access the device, the WWR MTK Tool
is a powerful option for generating a "temporary" or "empty" scatter file to help you perform a full ROM dump. Preparation MediaTek VCOM drivers and download WWR MTK (v2.51 or later). Generate Empty Scatter : Open WWR MTK, go to , and click "Generating empty scatter file" : Choose the chipset and select the memory type (usually
: Save this temporary scatter file to use in SP Flash Tool for a "Read Back" operation to extract the real partition data from your phone. Method 3: Using MTK Droid Tools (Older Devices) Mastering the MT6769: The Ultimate Guide to the

Understanding the MT6769 Scatter File: A Comprehensive Guide
The MT6769 is a popular system-on-chip (SoC) designed by MediaTek, a leading fabless semiconductor company. This SoC is widely used in various Android smartphones and tablets, offering a balance of performance and power efficiency. When it comes to flashing or modifying the firmware of devices powered by the MT6769, a specific file type becomes crucial: the scatter file. In this article, we'll delve into what a scatter file is, its importance, and how it relates to the MT6769 SoC, particularly in the context of "hot" or common modifications.

The scatter file is usually formatted in a way that each line represents a command or a piece of information. Here's a basic outline:
- LOADER

-NONE

When the phone has a corrupt preloader (no power, no USB detection), the only way to communicate with the CPU is via BROM. The "hot" method using test points is the last resort to write a clean preloader.
Below is a highly simplified example. Real scatter files can be much more complex and include more partitions.
