Mt6761 Scatter File Top Official

Here’s a helpful blog-style post about the MT6761 scatter file, focusing on the meaning of the "top" address and how to use it properly.

Critical Observations (The "Gotchas")

  • Region Addressing: The MT6761 often requires precise linear_start_addr values. A review of generic scatter files shows that offset errors of even a few blocks can result in a hard brick. A verified "Top" scatter file must align the boot and recovery partitions strictly after the nvram and protect1/2 partitions.
  • Dynamic Partitions: Some newer MT6761 devices use "super" partitions (dynamic system partitions). A legacy scatter file will miss this, rendering it useless for newer Android builds. A high-quality scatter file accounts for the super partition concatenation.

Repartitioning and resizing

  • Changing partition sizes in scatter requires corresponding changes in device parameters (GPT or MBR) and careful recalculation of start addresses.
  • For eMMC/GPT devices, use proper GPT tools to update partition table and ensure bootloader and preloader tolerate changes.
  • Avoid shrinking system partitions unless you know the minimal required size and update related metadata (e.g., fstab, super partition setups).
