The SP Flash Tool (Smart Phone Flash Tool) is the primary application for flashing custom or stock ROMs, firmware updates, and unbricking MediaTek (MTK) devices, including those powered by the MT6765 (Helio P35) chipset. Prerequisites Before you begin, ensure you have the following:
MediaTek USB VCOM Drivers: Essential for your PC to recognize the device in "Preloader" or "BROM" mode.
SP Flash Tool Executable: The latest version is generally recommended for newer chipsets like the MT6765.
Scatter File: A specific text file (Android_scatter.txt) found within the firmware folder of your exact phone model.
MTK Auth Bypass Tool: Often required for newer MTK chips (like MT6765) to bypass secure boot/authentication without a hardware dongle. Flashing Procedure
Launch the Tool: Extract the SP Flash Tool folder and run flash_tool.exe as an administrator.
Load the Scatter File: In the Download tab, click choose next to the "Scatter-loading File" field. Select the scatter file from your firmware directory. Select Flash Mode:
Download Only: Recommended for standard updates or fixes; it only overwrites partitions listed in the scatter file. sp flash tool mt6765 link
Firmware Upgrade: Used when the partition structure has changed.
Format All + Download: Caution: This will erase your IMEI and NVRAM data; use only as a last resort for hard-bricked devices.
Load Auth/DA Files (If Required): For secure boot devices like those with MT6765, you may need to select a specific Download Agent (DA) or an Authentication (.auth) file. Start Flashing: Click the Download button in the tool. Power off your device completely.
Connect the device to your PC via USB. For many MTK devices, you may need to hold the Volume Down or Volume Up button while connecting to trigger the correct mode.
Completion: A progress bar (red, then yellow) will appear. Once finished, a green circle with "OK" will confirm a successful flash. Safety Tips
Avoid "Format All": Only use this if you have a backup of your device’s unique calibration data (NVRAM), as it can permanently remove network capabilities.
Battery Level: Ensure your device has at least 30-50% battery before starting to prevent power failure during the write process. The SP Flash Tool (Smart Phone Flash Tool)
Exact Firmware: Never flash firmware intended for a different model, even if it uses the same MT6765 chipset, as this can lead to a hard brick.
Detailed guides and troubleshooting are available on community forums like Hovatek and GeeksforGeeks.
You cannot flash MT6765 without the correct DA file. The generic MTK_AllInOne_DA.bin often fails with STATUS_SEC_INVALID. You need a signed DA for MT6765.
➤ MT6765 DA Link: Search for DA_SLA_6765_6785_HVGA (available on valid tech forums like Hovatek). This file bypasses SLA/DAA security.
While MediaTek doesn’t provide a public "official" home page, the most trusted repository is GitHub or GSM Forum validated builds. As of 2025, the best version for MT6765 is SP Flash Tool v5.2324.

Here’s a technical write-up for using SP Flash Tool with a MediaTek MT6765 (e.g., Helio P35/G35) device, focusing on establishing a proper connection.
If the tool shows "No device found" or "Error: STATUS_EXT_RAM_EXCEPTION":
For newer MT6765 devices (e.g., Redmi 9C, Realme C11 2021), SP Flash Tool alone will fail with auth errors. Here’s the fix:
This creates a temporary "link" between the tool and MT6765’s secured BROM.
A: Yes, MT6765 enters BROM mode even with a dead boot. As long as you hear the USB connection sound, the tool can revive it via Format All + Download (but your IMEI will be lost – back up NVRAM first).
Newer MT6765 devices (Android 10+) include Secure Layer Authentication (SLA) and Download Agent Authentication (DAA). To bypass:
