Option 1 – Extract the True Scatter from Your Device (Recommended)

1. Root your MT3367 device (if possible – many car head units come rooted).

2. Use MTK Droid Tools (Windows) or a terminal with adb: mt3367 android scattertxt better new

   adb shell
   cat /proc/dumchar_info
   

   This shows the real partition names, start addresses, and sizes.

3. Convert that output into a proper scatter format. Example snippet: Option 1 – Extract the True Scatter from

   PRELOADER 0x0
   MBR 0x400000
   EBR1 0x440000
   PRO_INFO 0x480000
   NVRAM 0x680000
   PROTECT_F 0xa80000
   PROTECT_S 0xe80000
   ...
   

2. Scatter File Fundamentals

A scatter file (typically named MT3367_Android_scatter.txt) describes physical memory regions on the eMMC/NAND flash. Each partition is defined by:

• partition_name – Logical mount point (e.g., system, userdata)
• linear_start_addr – Physical address in flash
• partition_size – Byte length
• region – EMMC_USER (user data area) or EMMC_BOOT1/2 (boot partitions)
• storage – HW_STORAGE_EMMC
• type – NORMAL (file system) or PROTECTED (critical data)

How to Test if Your scatter.txt is "Better" and "New"

Load your scatter.txt in SP Flash Tool v5.2128+ or MTK Flash Tool. A valid, modern file will show: Root your MT3367 device (if possible – many

• Partition count ≥ 25 (older ones have 15–18)
• Inclusion of seccfg, expdb, logo, recovery, boot, system, vendor, product, super, userdata
• Logical block addresses (LBA) in hex, not decimal
• No overlapping partition ranges (check with a partition calculator)

If your scatter.txt flags an error like ERROR: S_DL_GET_DRAM_SETTING_FAIL (5054), it’s not compatible – you need a newer version.
