Solution: The MT6753 has a timer. You must click “Download” in SP Flash Tool before connecting the phone. Then, immediately connect the USB cable. If that fails, short the CLK or CMD pin on the eMMC (advanced users only).
Using the correct Download Agent can resolve the following issues:
Step 1: Launch SP Flash Tool
Run the executable file (flash_tool.exe) as Administrator.
Step 2: Load the Scatter File
Click the “Scatter-loading” button on the right. Navigate to your firmware folder and select the MT6753_Android_scatter.txt file. The tool will populate the memory regions.
Step 3: Load the Custom Download Agent This is the critical step for the MT6753:
Step 4: Configure the Mode Choose your action from the drop-down menu:
Step 5: Connect Your Device
Step 6: Observe the Process
If the DA file is correct, the SP Flash Tool will show a yellow progress bar, followed by a purple bar (DA execution), and finally a red/purple bar for flashing. You will see 100% and a green checkmark upon completion.
| Error | Likely Fix |
|-------|-------------|
| S_BROM_CMD_STARTCMD_FAIL | Wrong DA or device not in BROM mode. Reinstall VCOM drivers. |
| S_DA_SOC_CHECK_FAIL | DA file is not for MT6753. Get correct one. |
| S_BROM_DOWNLOAD_DA_FAIL | Preloader version mismatch. Try pressing Volume buttons when connecting. |

If you are searching for an MT6753 DA File, you are likely a technician or a user trying to revive a "dead" phone or bypass security (FRP). Here is the technical review of the file itself.
What is a DA File?
Types of DA Files for MT6753:
Why is the MT6753 DA File Popular? Because the MT6753 powered millions of devices (Blu, Infinix, Tecno, Lenovo, Meizu), technicians need specific DA files to unlock these older phones that are now out of warranty. Older MediaTek chips like the MT6735/53 often have "Secure Boot" enabled, preventing standard flashing. A custom DA file bypasses this restriction.
If you have the file but don't know how to load it, follow these steps carefully:
Before downloading a DA file, confirm your device uses the MT6753. Popular models include:
If your phone runs on Android 5.1 or 6.0 with a 1.3GHz – 1.5GHz octa-core processor, it likely houses an MT6753.
Preloader behavior: Often has secure boot or anti-rollback protection in stock firmware, requiring a custom or “auth bypass” DA to avoid errors like STATUS_SEC_AUTH_FILE_NEEDED or S_BROM_CMD_SEND_DA_FAIL.
