The scatter file relies on relative file paths. Ensure that all of your .img files ( recovery , boot , system , etc.) are located in the exact same folder as the .txt scatter file.

: Ensure the scatter file strictly matches your chipset (MT6577) and storage type (eMMC).
In this deep dive, we are looking at how to get results when flashing MT6577 devices by understanding the relationship between the Android Scatter file and the EMMCTXT partition. mt6577 android scatter emmctxt better
Understanding this file format is crucial for unbricking devices, creating custom partition layouts, and backing up firmware. Key Components of an MT6577 Scatter File
For the MT6577 chipset, you must use a scatter file specifically designated for eMMC storage
The EMMC.txt method accurately defines the separate boot blocks ( ROM_BOOT1 and ROM_BOOT2 ) where the preloader resides. This prevents accidental overwriting of the critical phone bootloader. The scatter file relies on relative file paths
Think of your device's storage as a vast, unlabeled warehouse. This scatter file acts as a detailed floor plan, telling any compatible tool (most notably, SP Flash Tool) exactly where to place, read, or erase every single piece of software that makes your phone run. Without it, the PC has no idea where to put the system, where the bootloader begins, or where your personal data should be stored.
