The file is a critical map used by MediaTek flashing tools (like SP Flash Tool ) to communicate with devices powered by the MediaTek Dimensity 700 (MT6833) chipset. It acts as a set of instructions that tells the flashing software exactly where each partition—such as the system, recovery, or preloader—is located on the device's storage. Core Function & Purpose
: The primary bootloader that initializes the hardware. It is the first file flashed and is vital for device recovery.
A scatter file is a raw text document used exclusively by MediaTek (MTK) processors and flashing software like SP Flash Tool. It contains a structured layout of the device's storage (eMMC or UFS).
When working with an MT6833 device, certain partitions require strict attention to avoid permanent bricking or data loss:
The scatter file lists many partitions. Here is a breakdown of the most critical ones: Mt6833 Android Scatter.txt
Let’s open a typical scatter file for the Redmi Note 10 5G (codename: camellia ). You’ll see a structured text block. Here is a breakdown:

| Symptom | Likely Cause | Solution | |---------|--------------|----------| | SP Flash Tool says “Invalid scatter file” | Line ending mismatch (LF vs CRLF) | Open in Notepad++, convert to Windows (CR LF) | | “Partition ‘super’ size mismatch” | Your device has a different super partition size | Get correct firmware; or edit scatter’s partition_size to match fastboot getvar super | | Flashing stops at “Download DA 100%” | USB driver issue or broken scatter | Reinstall MediaTek USB VCOM drivers; use USB 2.0 port | | Error: “STATUS_PRELOADER_INVALID” | Preloader file name in scatter doesn’t match actual file | Rename the .bin file to match the file_name field |
Developers use the scatter file to determine where to flash a Generic System Image (GSI). Since MT6833 uses logical partitions inside super , you cannot directly flash system.img . Instead, you must decompress super using lpunpack , replace the logical images, then repack. The scatter file’s super partition size tells you the maximum size allowed. The file is a critical map used by
:
The file is used to flash a patched boot image.
Click on the Choose button next to the Scatter-loading File field. Navigate to your extracted stock firmware folder and select MT6833_Android_scatter.txt .
While it is a plain text file and can be opened with any text editor (like Notepad++), a MediaTek scatter file follows a strict syntax. It is divided into two main sections: GeneralSetting and LayoutSetting . It is the first file flashed and is
Advanced users can modify the scatter file for specific tasks:
Each partition on the phone (such as boot , recovery , super , or userdata ) has its own dedicated block of code. A typical partition entry looks like this:
For developers and advanced users, the MT6833_Android_scatter.txt is the gateway to custom ROM development. It is used in the following ways:
A massive container partition housing system , vendor , and product sub-partitions dynamically.
The bulk of the file consists of individual blocks for every partition on the phone (e.g., preloader , boot , super , userdata ). A standard partition entry looks like this:
