If your MT6577 device still boots to Android but you want to back up the scatter/emmc link:

The "link" is typically found inside the Scatter file syntax. A standard MT6577 scatter file might look like this:

for block in blocks[1:]: # skip first empty part = self._parse_partition_block(block) if part: self.partitions.append(part) region = part.get('region', 'EMMC_USER') if region in self.emmc_layout: self.emmc_layout[region].append(part) else: self.emmc_layout.setdefault(region, []).append(part)

You typically find the MT6577_Android_scatter_emmc.txt inside the official stock ROM or firmware folder for your specific device.
