Mt6765 Da File
Many modern MT6765 devices have DA authentication enabled by default, making it hard to flash with unofficial software. This is where bypass tools come in:
For the MediaTek MT6765 (Helio P35) chip, this specific file allows the tool to bypass security, read partition information, and flash firmware onto the device's eMMC or UFS storage.
The MT6765 DA file acts as a critical bridge between your computer and your smartphone's hardware. Without it, many flashing tools simply cannot "talk" to the chip once secure boot is enabled. Life-Saving Recovery:
When a MediaTek device is connected to a PC in , the processor pauses and waits for instructions. The Flash Tool sends the DA File to the device's internal SRAM. The device then executes this file, which allows the tool to take control of the device's storage (eMMC or UFS) to read, write, or erase partitions.
To modify the system, the DA file helps in reading/writing partitions. Mt6765 Da File
You connect the device. You click "Download." The red bar fills 100%, then... nothing. Or you get S_BROM_CMD_STARTCMD_FAIL .
| Error Code | Meaning | DA Solution | | :--- | :--- | :--- | | | DRAM initialization failed. The DA's memory map is wrong. | Find a DA compiled for LPDDR4x (MT6765 specific). | | S_BROM_CMD_SEND_DA_EXT | Preloader rejected the DA signature. | Use an Auth Bypass DA or short the CLK pin to force BROM. | | STATUS_DEVICE_BROM_CMD_SEND_DA_FAIL | USB handshake timeout. | You need a Preloader DA (MTK All-In-One DA). |
What are you using? (SP Flash Tool, UnlockTool, MTK Meta Utility?)
Fix: Re-install the MediaTek VCOM drivers, change the USB cable, or use an MTK Auth Bypass utility to force open the port. Many modern MT6765 devices have DA authentication enabled
Performing a factory reset when the screen is locked. How to Use the MT6765 DA File If you are using the SP Flash Tool , follow these steps:
If you are using a modern MT6765 device (manufactured after 2022), you may also need a or an MTK Auth Bypass Tool to disable the SLA/DAA security before the DA file can do its job.
This is why a specific, often for the MT6765 is so important. For the most secure devices, even a correct signed DA file may not be enough. Some manufacturers require an authorized account to be logged into the flashing tool before it will work, a security measure that a DA file alone cannot bypass.
Once the DA file is loaded into the device's RAM, it initializes the hardware components necessary for flashing: Without it, many flashing tools simply cannot "talk"
If you are installing a full OS, stay on the tab and select Download Only from the dropdown menu. Never select "Format All + Download" as this will erase your unique IMEI configuration. Click the Download (or Start ) button.

If you use a generic DA file on a phone with Secure Boot enabled, the tool will throw fatal errors such as: STATUS_SEC_AUTH_FILE_NEEDED STATUS_DA_SELECTION_ERR BROM ERROR: ?? (0x7000)
A green checkmark. If you see Error 0x2e78 , your DA is incorrect for that security version.
The DA file reports the status of the hardware back to the PC tool:
