Mt6769z Scatter File
You can manually edit:
But never change partition order or region boundaries unless you know exactly what you're doing.
Example: Changing system size (requires resizing adjacent partitions and fixing GPT). mt6769z scatter file
Because the MT6769Z scatter file includes PROTECTED partitions, using the standard SP Flash Tool requires a specific DA (Download Agent). The interesting trick: If you take a scatter file from a Redmi 10C (which uses the MT6769Z) and try to flash it to a Doogee N20 Pro (same chip), the flash tool will silently skip the nand_temp partition. This results in a "Ghost Brick"—the phone boots, the screen lights up, but touch is inverted on the X-axis.
Common partitions you'll see:
| Partition | Description |
|-----------|-------------|
| preloader | First-stage bootloader (low-level HW init) |
| pgpt | Primary GPT (partition table) |
| lk / bootloader | Little Kernel (second-stage bootloader) |
| boot | Kernel + ramdisk (boot image) |
| recovery | Recovery image |
| system | Android system image |
| vendor | Vendor-specific system files |
| userdata | User data + internal storage |
| cache | Cache partition |
| tee | Trusted Execution Environment |
| metadata | Encryption metadata |
| seccfg | Secure config (bootloader lock state) |
| nvram | IMEI, Wi-Fi MAC, BT address |
| protect1/2 | NVRAM backup |
| vbmeta | Verified boot metadata |
A scatter file is a text file that contains information about the layout of the firmware components on a mobile device. It is used by flashing tools, such as SP Flash Tool, to identify the correct locations of the firmware components, such as the bootloader, kernel, and system image, on the device's memory. You can manually edit:
| Partition Name | Purpose |
| :--- | :--- |
| preloader | Initial bootloader. Never flash this unless absolutely necessary—a mismatch hard bricks the device. |
| md1img | Modem firmware (baseband, IMEI handling). |
| lk / lk2 | Little Kernel (secondary bootloader, handles fastboot). |
| boot | Kernel + ramdisk. Flashing custom kernels modifies this. |
| recovery | Recovery environment (TWRP or stock recovery). |
| system | Android OS framework (read-only). |
| vendor | Proprietary binaries and drivers (including MT6769Z-specific HALs). |
| userdata | User apps, settings, and internal storage. |
| cache | Temporary system cache. |
| nvram | Stores Wi-Fi MAC address, Bluetooth address, and IMEI. Critical to back up. |
| protect1 / protect2 | Security-related data (S擎). |
| seccfg | Secure boot configuration and unlock status. |
