Let’s dissect the CHM-U01’s scatter file not as a simple partition table, but as a low-level hardware blueprint. In the world of MediaTek (MTK) chipsets—which power the CHM-U01 (MT6735P)—a scatter file describes how the eMMC (embedded MultiMediaCard) flash memory is partitioned in physical address space . Unlike high-level block devices ( /dev/block/mmcblk0pX ), the scatter file works at the pre-bootloader level. SP Flash Tool, the standard flashing utility for MTK devices, uses this file to write raw data to exact physical offsets.

If you’ve ever downloaded a stock firmware package for a Huawei CHM-U01 (better known as the Huawei Y6 Pro or Honor 5A in some markets), you’ve likely encountered a small but critical file with the .xml extension: the scatter file . To the uninitiated, it looks like a messy list of hexadecimal addresses. But to those who reverse-engineer, repair, or unbrick Android devices, the scatter file is the Rosetta Stone of the device’s storage architecture.

Alternatively, dump the GPT:

For the curious repair technician: the scatter file is where software meets silicon. Treat it with respect. Need a specific CHM-U01 scatter XML example or help recovering from a bad flash? Leave a comment.
