The MT6755 scatter file is a text document used by the SP Flash Tool to define the memory map and partition structure of a MediaTek MT6755 (Helio P10) chipset. It acts as a roadmap for the flashing process, specifying exactly where each firmware component (like the preloader, boot, or recovery) should be written on the device's eMMC storage. Key Components of an MT6755 Scatter File
| 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 | mt6755+scatter+file+verified
This is the most critical meaning for security. The MT6755 includes a BootROM that cryptographically verifies the PRELOADER using an e-fused key. Then, PRELOADER verifies UBOOT, which verifies BOOTIMG (if secure boot is enabled). This is part of MediaTek’s Secure Boot and Google’s Verified Boot (AVB). The MT6755 scatter file is a text document
A scatter file is a text file used in the flashing process of Android devices, particularly those with MediaTek chipsets like the MT6755. The file contains information about the layout of the device's storage, including the locations of various partitions such as the bootloader, kernel, and system. it was finding one that was
Below is a sanitized example from a typical MT6755 device:
The challenge wasn't just finding a scatter file; it was finding one that was
