If you compare the MT6577 eMMC scatter files to older MTK scatter files designed for NAND memory ( MT6575_Android_scatter_nand.txt ), the eMMC version is superior in several distinct ways: 1. Robust Bad Block Management

: The _emmc suffix indicates that the device uses embedded MultiMediaCard storage rather than older NAND flash. This is critical because the addressing systems for NAND and eMMC are fundamentally different. Why "emmctxt better"?
If the file is named recovery.img , the scatter entry must point to recovery.img . Case sensitivity matters in legacy MediaTek environments. Step-by-Step Guide to Read and Flash Firmware
The "emmc" suffix indicates the file is specifically formatted for modern Embedded MultiMediaCard storage rather than older NAND layouts.
