To read the NVRAM partition from eMMC using the scatter file offsets:

# Under Linux, with eMMC as /dev/mmcblk0
# NVRAM starts at hex 0xA40000 (decimal 10747904), size 0x460000 (4587520 bytes)
dd if=/dev/mmcblk0 of=nvram.bin bs=512 skip=20992 count=8960
# (skip = 0xA40000 / 512 = 20992, count = size/512)

eMMC (embedded MultiMediaCard) is a type of storage commonly used in mobile devices. It offers a compact, high-capacity storage solution that is relatively fast and reliable. The eMMC storage is divided into several partitions, each with a specific function, such as:

A scatter file (or scatter layout file) is a plain text configuration file that describes the partition table of an Android device’s embedded MultiMediaCard (eMMC). For MT6589 devices, its exact naming convention is often: To read the NVRAM partition from eMMC using

| Error | Likely Cause | Fix | |-------|--------------|-----| | Status_BROM_CMD_SEND_DA_FAIL | Wrong scatter file for this eMMC | Find correct MT6589_Android_scatter_emmc.txt specific to your sub-model. | | PMT changed for the ROM | Partition table mismatches between scatter and flashed ROM | Use “Firmware upgrade” instead of “Download” in SP Flash Tool. | | S_FT_ENABLE_DRAM_FAIL | Preloader address is wrong | Verify PRELOADER starts at 0x0 and size is at least 0x40000. | eMMC (embedded MultiMediaCard) is a type of storage

On a running Android system (rooted), the file might appear as a symbolic link. For example:

/some/path/MT6589_Android_scatter_emmc.txt -> /dev/block/mmcblk0

Or it could be a link from a generic name to the actual scatter file stored in /etc/firmware/. On a running Android system (rooted), the file

Why a symlink?
Manufacturers sometimes use symlinks to maintain compatibility across multiple storage types (eMMC vs. NAND). The linked file points to the current active partition layout.

For MT6589 devices, the internal storage is eMMC (not raw NAND). This means:
