The Ultimate Guide to the MT6833 Scatter File: Structure, Usage, and Firmware Flashing

2. What Partitions are in an MT6833 Scatter File?

A typical MT6833 scatter file contains 30–50 partitions. Key ones:

| Partition | Purpose | |-----------|---------| | preloader | Low-level bootloader (first code on CPU) | | pgpt | Primary GPT (partition table) | | nvram | IMEI, WiFi/BT MAC addresses, calibration data | | persist | Sensor calibration, DRM keys | | boot | Linux kernel + ramdisk | | dtbo | Device tree blob overlay | | vbmeta | Verified boot metadata (AVB) | | super | Dynamic partitions (system, product, vendor, odm) | | userdata | /data partition (user apps + settings) | | md_udc | Modem firmware | Mt6833 Scatter File

⚠️ Never flash someone else's nvram or persist – you will lose IMEI and network functionality. The Ultimate Guide to the MT6833 Scatter File:

  • Preloader authentication – Some MT6833 devices (Xiaomi, Realme) require an authenticated DA (Download Agent). Use tools like mtkclient or authorized SP Flash Tool version.
  • BROM mode – Newer MT6833 security may block brom access. You may need to short test points or use bootrom-exploit.
  • Super partition size – Flashing mismatched super.img size causes STATUS_PARTITION_SIZE_ERROR.
