Without this exact mapping, SP Flash Tool would corrupt nearby partitions, leading to a hard brick.

A legitimate MT6755 scatter file for AOSP-based devices has these fixed constraints:

Any deviation beyond ±10% is a red flag.

Using MTK Client or SP Flash Tool (Read Back): mt6755+scatter+file+verified

# Using mtkclient (Linux)
mtk r scatter MT6755_dumped_scatter.txt

The dumped file is verified by existence but not cryptographically signed.

If you have a bricked phone but downloaded a suspicious scatter file, verify it offline using these methods:

Even with a scatter file, SP Flash Tool may throw errors. Here’s how your verification solves them: Without this exact mapping, SP Flash Tool would

| Error Code | Meaning | How Verified Scatter Helps | |------------|---------|----------------------------| | STATUS_BROM_CMD_SEND_DA_FAIL (0xC0060005) | Preloader mismatch | Verified scatter ensures the exact preloader.bin address and file size | | S_SECURITY_AC_REGION_NOT_FOUND (0x7003) | Wrong partition region type | Verified scatter corrects the region field (EMMC vs EMMC_USER) | | STATUS_EXT_RAM_EXCEPTION (0xC0050005) | Memory address overflow | Verified scatter prevents non-existent address ranges | | ERROR: S_FT_NEED_DOWNLOAD_ALL_FAIL | Partition size mismatch | Verified scatter matches partition sizes exactly to eMMC geometry |

Real-world case: A user trying to flash a “generic MT6755 scatter” on a Vivo V3Max got STATUS_EXT_RAM_EXCEPTION because the boot partition address was off by 0x20000 bytes. After obtaining the verified scatter from the official Vivo firmware package, the flash succeeded instantly.

Via ADB (root required):

adb shell
su
dd if=/dev/block/mmcblk0 of=/sdcard/mbr.img bs=512 count=1

Then use readback in SP Flash Tool using a known working scatter, or use MTK Droid Tools (archived version 2.5.3) to generate a scatter from the live device.

Some MT6755 stock ROMs have enabled Anti-Rollback, where the partition sizes or meta-data change after official updates. A non-verified scatter file may skip the secro or protect_f partitions, causing IMEI loss or encryption errors.

Original scatter files include bad block mapping strategies. Generic ones do not. On old MT6755 eMMC chips (which degrade over time), a non-verified scatter file can lead to repeated write failures or partition corruption. A legitimate MT6755 scatter file for AOSP-based devices

A verified scatter file means:
