An MT6833 scatter file typically looks like this: mt6833 android scattertxt exclusive

- partition_name: boot
  file_name: boot.img
  is_download: true
  type: NORMAL

Most generic scatter files for MediaTek are copy-pasted from old chips. An exclusive MT6833 scatter.txt is one that has not been modified by generic SP Flash Tool aggregators. It respects the specific partition boundaries of 5G modems (like the md1img partition) and advanced DRM partitions (seccfg, persist).
Without the correct scatter file, you will face S_DL_GET_DRAM_SETTING_FAIL (5054) or STATUS_DEVICE_CTRL_EXCEPTION errors in SP Flash Tool. // Exclusive scatter

Look for stock ROMs labeled with:
If your phone is rooted:
adb shell
su
dd if=/dev/block/mmcblk0 of=/sdcard/scatter.txt bs=4096 count=1 # This doesn't work directly.
# Actually, use MTK-Metadata:
cat /proc/partitions
# Then use MTK Droid Tools (Legacy) or MTK Client (Modern) for Python.

Modern Tool: Use mtkclient (GitHub). Connect via BROM mode (Volume Up + Down). Run:
python mtk printparts > mt6833_scatter.txt
A Scatter file is a text-based map used by the SP Flash Tool (Smart Phone Flash Tool) to locate partitions within the NAND/eMMC/UFS storage of a MediaTek device. It tells the flashing tool: An MT6833 scatter file typically looks like this:
Two phones with the same MT6833 chip can have drastically different partition tables. For example:

Flashing the wrong super partition size corrupts logical partitions inside (system_a, system_b, product).
