It acts as a blueprint that tells the tool exactly where each part of the firmware—such as the bootloader, recovery, or system—should be written on the eMMC storage. Key Features of MT6755 Scatter Files
Partition Layout Mapping: Defines 24–28 sequential partitions, including critical regions like the preloader, recovery, boot, userdata, and modem.
Memory Addressing: Specifies the exact linear and physical start addresses (e.g., beginning at 0x0) and the length for each partition.
Flashing Control: Each section within the file contains flags that determine if a partition is downloadable, upgradeable, or protected/invisible.
Storage Compatibility: Specifically configured for devices using the ARM-based MT6755 architecture with eMMC storage types.
IMEI & NVRAM Repair: Often used in conjunction with tools like Wwr MTK or MTK Droid Tools to restore NVRAM data and fix IMEI issues after a firmware flash. Common Uses UMi Super TWRP and root UMi Super MT6755 Helio P10
MT6755 Chipset Overview
The MT6755, also known as the Helio P10, is a mid-range smartphone processor developed by MediaTek, a Taiwanese semiconductor company. It was released in 2015 and is built using a 28nm process. The chipset features an octa-core CPU, a Mali-T860MP2 GPU, and supports up to 4GB of LPDDR3 RAM.
Scatter File
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. mt6755+scatter+file+verified
Here's an example of a scatter file for the MT6755:

The MT6755 chipset, also known as the Helio P10, is a widely used MediaTek processor found in mid-range devices like the Oppo F1s, UMi Super, and Blackview BV6000. Managing the firmware for these devices requires a specific scatter file, which acts as a map for the phone's internal storage partitions. MT6755 Android Scatter File Overview
The scatter file (typically named MT6755_Android_scatter.txt) is a configuration document that defines the partition layout on the device's eMMC storage. It provides the starting physical addresses and sizes for crucial software components, including:
Preloader: The initial bootloader that handles communication between the PC and the device.
Recovery & Boot: Standard partitions for the OS kernel and recovery tools like TWRP.
System & Userdata: The primary storage for the Android OS and user-installed applications.
Modem/Firmware: Files necessary for cellular connectivity and hardware communication. Flashing and "Verified" Files
When searching for "verified" files for the MT6755, you are typically looking for firmware images that have been tested and confirmed to boot without bricking the device.
Verified Boot (AVB): Modern MTK devices use Android Verified Boot (AVB) to ensure the integrity of partitions like the preloader and system. Using tools like Flash64 or Hydra Tool can help verify these signatures during the flashing process. Unlocking the Power of MT6755: A Comprehensive Guide
Safe Flashing: Always ensure the scatter file matches your specific hardware variant. A scatter file for a 32GB model may not be compatible with a 16GB version of the same phone. Essential Tools

Comprehensive Guide to MT6755 Verified Scatter Files The MT6755, better known as the MediaTek Helio P10, is a popular octa-core chipset that powered many mid-range smartphones during its peak. If you are looking to unbrick, update, or root a device with this processor, obtaining a verified scatter file is the most critical step in the process. What is an MT6755 Scatter File?
A scatter file (typically named MT6755_Android_scatter.txt) is a configuration file used by the SP Flash Tool to understand the memory structure of a MediaTek device. It serves as a map for the flashing tool, indicating exactly where each part of the firmware (like the preloader, recovery, and system images) should be written on the device's eMMC storage.
A "verified" scatter file is one that has been confirmed to match the specific partition layout of a particular phone model, such as the UMi Super or Oppo F1s. Using an incorrect or unverified file can lead to a "chipset mismatch" error or, worse, a hard-bricked device. Technical Breakdown of the MT6755 Partition Layout
The MT6755 chipset typically manages between 24 and 28 distinct partitions. Key sections defined in a verified scatter file include:
Preloader: The initial boot code; flashing the wrong preloader is the most common cause of hard bricks.
Recovery: Often replaced with TWRP for rooting and custom ROM installation.
System/Userdata: These hold the Android OS and your personal files.
Modem (md1img, md1dsp): Essential for cellular connectivity. How to Use a Verified Scatter File
To flash your MT6755 device, you will need the SP Flash Tool, the MediaTek VCOM Drivers, and your verified firmware pack.
[Revised] How to use SP Flash tool to flash Mediatek firmware
Verified, in the MTK world, isn't about digital signatures. It's about checksums and provenance.
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.
But even that could be corrupted. So he performed the three rites of verification:
partition_size for system against the actual system.img size. The scatter file said 0x80000000 (2GB). The image was 1.9GB. Pass.linear_start_addr of each partition. No overlaps. The preloader ended at 0x0 to 0x40000. The next partition, pgpt, started exactly after. Pass.nvram partition’s backup file in a hex editor. The first 16 bytes contained the manufacturer’s magic number: VIVO_P10_NVRAM_V1. The scatter file’s region for NVRAM was set to EMI_USER. Verified.Only then did Leo proceed.
In the Mediatek factory supply chain, “verified” means the scatter file has passed the MTK_DA_PL_Check tool. This tool checks the DA (Download Agent) compatibility and the SHA-1 of the partition layout table against the phone’s boot ROM. A “verified” scatter will never produce a BROM ERROR: S_BROM_CMD_STARTCMD_FAIL.
