| Official OEM firmware (ZIP) | Highest | Extract from MT6755_Android_scatter.txt inside factory ROM |
| Firmware Update (Official OTA payload) | High | MD5 checksums match the stock ROM dumps |
| Scatter from same device (backup) | High | Compare with cat /proc/partitions via ADB |
| Trusted repositories (NeedROM, MTK Firmware) | Medium-High | Community-verified hash lists |
Verified, in the MTK world, isn't about digital signatures. It's about checksums and provenance. mt6755+scatter+file+verified
Leo extracted the original firmware from a backup server—a full Vivo_X9_MT6755_6.0.1_Original_Stock.zip. Inside, alongside system.img and boot.img, was a file: MT6755_Android_scatter.txt. | Source | Reliability | Verification Method |
But even that could be corrupted. So he performed the three rites of verification: Only then did Leo proceed
Only then did Leo proceed.
- partition_index: SYS5
partition_name: boot
file_name: boot.img
is_download: true
type: NORMAL
linear_start_addr: 0x1a200000
physical_start_addr: 0x1a200000
partition_size: 0x1000000
Without this exact mapping, SP Flash Tool would corrupt nearby partitions, leading to a hard brick.
