The partition table structure on the phone differs from the layout defined in the new scatter file.
Once you have the scatter file, it must be loaded into a compatible MediaTek flashing utility. 1. SP Flash Tool (Smart Phone Flash Tool)
use it to create an exact image of the phone's current state.
Modifying system partitions carries an inherent risk of bricking your device. Always back up your data prior to flashing. If your device loses network capability (IMEI) after flashing, you will need to restore your NVRAM or NVDATA backup using specialized MediaTek service tools. Always double-check that the scatter file architecture matches before clicking download.

Click the button next to the Scatter-loading File field.
Note: While these devices share the MT6769Z processor, you cannot use a scatter file from a Redmi 9 to flash an Infinix Hot 10S. The partition structure must match your exact brand, model, and region. How to Get the MT6769Z Scatter File
Before diving into scatter files, it helps to understand the chipset itself. The MediaTek MT6769Z, marketed as the Helio G85, is an octa-core processor built on a 12nm manufacturing process. It features a hybrid CPU architecture with and six power-efficient Cortex-A55 cores running at 1.8 GHz , complemented by a Mali-G52 MC2 GPU.

Before modifying a phone, developers use the scatter file addresses to read and back up the unique, device-specific data (like IMEI and NVRAM network calibration data). Where to Download the MT6769Z Scatter File
Download the firmware zip from trusted sources (e.g., official brand forums, Mi Firmware, SamFw, or GSM Forum). Extract the archive using WinRAR or 7-Zip.
The best way to obtain the correct scatter file is from the for your specific phone model (e.g., Infinix, Xiaomi, Vivo, Tecno using Helio G80). It is usually located inside the firmware folder as a .txt file. 2. How to Use in SP Flash Tool
| Partition | Purpose | Critical Level | |-----------|---------|----------------| | preloader | First-stage bootloader; initializes hardware and loads subsequent boot components. If corrupted, the device won’t even power on | | | pgpt | Primary GUID Partition Table; defines the partition structure for the entire device | Extreme | | boot | Linux kernel and ramdisk; contains the Android boot image | High | | recovery | Recovery environment for factory resets and OTA updates | Medium | | vbmeta | Verified boot metadata; secures the boot chain with cryptographic signatures | High | | super | Dynamic partition containing system, product, vendor, and other read-only partitions | High | | userdata | User-installed apps, settings, and personal data | Low (can be wiped) | | nvram | IMEI, Wi-Fi MAC address, Bluetooth address, and other device identifiers | Critical to back up | | nvdata | Additional calibration and configuration data | Critical to back up | SP Flash Tool (Smart Phone Flash Tool) use
Using a scatter file from a different model (even if it uses the same chipset) can permanently damage your phone.
A scatter file is a text file that contains information about the layout of the memory on a device. It provides a map of the device's memory, specifying the starting and ending addresses of various memory regions, such as the bootloader, kernel, and system partitions. This file is used by flashing tools, such as SP Flash Tool, to guide the process of writing data to the device's memory.
