On older MediaTek NAND chips (e.g., MT6575, MT6515), the scatter file included extra parameters like page size , spare size , and bad block management because NAND required ECC and skip bad blocks. mt6577 android scatter emmctxt better
To use this file for a "better" experience (i.e., one that doesn't end in a broken device): If you receive an error stating the "scatter
This post is a forensic analysis of that text file, the eMMC protocol, and why the MT6577 sits at a unique crossroads in mobile storage history. the eMMC protocol
On the MT6577, if your Scatter file does not correctly define the EMMCTXT region—or if the region size is mismatched—the SP Flash Tool may refuse to write the firmware because it cannot calculate the correct storage boundaries.
If you receive an error stating the "scatter storage type is HW_STORAGE_EMMC" but the "target storage type is NAND" (or vice versa), the scatter file is trying to write data to the wrong physical hardware. How to obtain or create a "Better" Scatter File
