Cause: Scatter file assumes a larger eMMC than what is physically present (e.g., scatter for 32GB, device has 16GB).
Fix: Manually edit the scatter.txt: change USRDATA linear start address or set size to 0x0 to auto-calculate.
John had been an Android enthusiast for years. He loved experimenting with different ROMs and firmware on his devices. Recently, he acquired an older smartphone based on the MediaTek MT3367 chipset. His goal was to breathe new life into this device by installing a custom ROM. mt3367 android scatter.txt
However, John quickly encountered a significant hurdle. The device wasn't recognized properly by the SP Flash Tool, and he couldn't find a compatible "scatter.txt" file for his specific device model. Without this file, he couldn't proceed with flashing any firmware. Cause: Scatter file assumes a larger eMMC than
Determined, John started his search online, scouring through forums and websites dedicated to Android development and MediaTek devices. He encountered several threads discussing the challenges of finding the correct scatter files for various devices but found nothing specific to his model. | Error | Solution | | :--- |
The scatter.txt file is a partition layout table used by SP Flash Tool (or custom flashing tools) to write firmware to the eMMC chip. For the MT3367, this file is critical because these head units often lack recovery mode or fastboot.
Example (illustrative only — do NOT use without verification):
- partition_index: SYS0
partition_name: PRELOADER
file_name: preloader.bin
is_download: true
type: NORMAL_ROM
linear_start_addr: 0x00000000
size: 0x00040000

| STATUS_EXT_RAM_EXCEPTION | Wrong preloader. Re-flash correct PRELOADER and PGPT. |
| S_BROM_DOWNLOAD_DA_FAIL | DA (Download Agent) mismatch. Use the DA file that came with your firmware. |
| PMT changed for the ROM | Scatter doesn't match current eMMC layout. Must use "Format All + Download". |
| Error: STATUS_SEC_AUTH_FILE_NEEDED | Auth file required. Disable "Security" in SP Flash Tool settings. |
