There are two primary methods to acquire a clean, functional scatter file for your phone.
If your phone is still working and you want to back up your current layout: Enable USB Debugging on your phone.
You must download an MTK Auth Bypass tool to temporarily disable this security layer before clicking "Download" in SP Flash Tool. 2. Error: PMT changed for the ROM
Click the button next to the Scatter-loading File field.
Creating a scatter file for the MT6761 (commonly known as Helio A22) is challenging because the file structure depends heavily on the specific device's partition layout (e.g., how big the system, cache, and userdata partitions are).

If you need to wipe a specific section, you can use Notepad++ to find the "begin address" and "format length" from the scatter file to enter into the tool's manual format tab.
Understanding and Using the MT6761 Scatter File for Firmware Flashing
[partition_name:efuse] partition_index: = 3 file_name: = efuse.img is_download: = false partition_type: = EMMC linear_start_addr: = 0x380000 physical_start_addr: = 0x380000 partition_size: = 0x20000 region: = USER storage: = HW_STORAGE_EMMC boundary_check: = true reserved: = false operation_type: = PROTECTED d_type: = 0 reserve: = 0x0 is_upgradable: = true
Once you have your firmware folder and your new scatter file ready, follow these steps to flash your device. Step 1: Bypass Secure Boot (Authentication) Open your . Click on the Bypass button. Turn off your MT6761 phone completely.
: Modern MT6761 chips feature secure boot protection. You may need an SLA/DA bypass utility to disable this security layer before SP Flash Tool can write data.
Each partition is defined by a block of code similar to the example for the recovery partition below:
[partition_name:boot] partition_index: = 5 file_name: = boot.img is_download: = true partition_type: = EMMC linear_start_addr: = 0x4A0000 physical_start_addr: = 0x4A0000 partition_size: = 0x1000000 region: = USER storage: = HW_STORAGE_EMMC boundary_check: = true reserved: = false operation_type: = INVISIBLE d_type: = 0 reserve: = 0x0 is_upgradable: = true
The MT6761 scatter file serves as the primary map for the device's internal storage (eMMC or UFS). It instructs the flashing tool on the precise memory addresses (offsets) where specific partitions and firmware images must be written.
