Warning: "Download Only" will skip the preloader and partition table. If your preloader is corrupt, this may still fail. But it avoids unnecessary DA handshake interruptions.
The most common user error: wrong connection order.
Correct procedure:
If stuck at 100% DA:
If none of the above works, the preloader region of the eMMC is likely corrupt beyond BROM's ability to bypass. In this state, the phone won't even accept the DA.
You will need:
Once connected, write a known-good preloader binary (extracted from your stock ROM) directly to the eMMC at offset 0x0. After rewriting the preloader, the phone will re-enter BROM mode normally, and SP Flash Tool will sail past 100% DA.
This is an advanced repair method for technicians only.
Before giving up, verify each:
If you’ve completed all 12 solutions and the yellow bar still reads "Download DA 100%" for more than 2 minutes, your phone’s eMMC is likely physically dead. In that case, only a chip replacement will bring it back to life.

List of sp flash tool error codes, meanings & how to fix (solution)
When using the SP Flash Tool, seeing the yellow progress bar reach Download DA 100%
and then stop is a frustrating but common bottleneck. This state usually signifies that the "Download Agent" (DA)—the small piece of software that communicates with your device's internal storage—has successfully loaded into the phone's SRAM, but the tool is failing to transition to the actual firmware flashing stage. Stack Overflow Why the Tool Gets Stuck at 100%
The "Download DA 100%" freeze is rarely a software "crash" and more often a communication or compatibility breakdown . Key reasons include: Secure Boot Conflict
: Many modern MediaTek devices (like those from Xiaomi or Oppo) have a secure bootloader that requires a specific "Secure DA" file to authorize the flashing process. Driver Handover Failure
: The PC might successfully send the DA file but fail to switch to the MediaTek VCOM driver required for the subsequent data transfer. Hardware Interruption
: Issues like a faulty USB cable, a loose port, or insufficient battery power can cause the target device to shut down unexpectedly right after the DA is received. Step-by-Step Solutions 1. Use a Secure Download Agent (DA) If your device has a secure bootloader, the default MTK_AllInOne_DA.bin might not work. Locate the specific DA : Look for a file named DA_SWSEC.bin
or a DA file specifically provided with your phone's stock firmware. Select it in the tool : In the SP Flash Tool interface, click the button next to Download-Agent and select the specialized 2. Re-install or Force VCOM Drivers
The jump from 100% DA to the actual download requires a stable VCOM connection. Manual Install Device Manager
, right-click your computer name, and select "Add legacy hardware" to manually install MediaTek Preloader USB VCOM Port Check
: Ensure you are using a direct USB port on your motherboard (back of the PC) rather than a USB hub or front-panel port, which may lack sufficient power. 3. Hardware Interaction (Key Combos)
Sometimes the device needs a physical "nudge" to enter the correct state after the DA is sent. The Volume Trick : Try holding Volume Down
(or sometimes Volume Up, or both) while connecting the USB cable. Do not release them until the progress bar moves past the yellow DA stage. Power Reset
: If the phone has a removable battery, take it out and put it back in before starting. Ensure the phone is completely switched off before connecting. 4. Tool & File Configuration The most common user error: wrong connection order

Smart Phone Flash Tool (SP Flash Tool) becomes stuck at "Download DA 100%," it signifies a critical communication breakdown between the computer and the MediaTek (MTK) device. While the progress bar indicates that the Download Agent (DA) has been successfully sent to the device's internal memory, the software is unable to proceed to the next phase—usually the flashing of actual firmware partitions like the preloader or system. Resolving this issue requires a systematic approach to identifying whether the bottleneck is hardware, driver, or software-related. Root Causes of the "DA 100%" Stall
The primary reason for this stall is that the flash tool is waiting for a response from the device that never arrives. This can be caused by: Driver Conflicts : Improperly installed or outdated VCOM drivers
prevent the tool from maintaining a stable connection once the initial handshake (the DA stage) is complete. Secure Boot Requirements
: Newer devices often require a specific "Secure Boot" Download Agent or an authentication file (auth file) to authorize the flashing process. Physical Connectivity
: A faulty USB cable, a damaged port, or insufficient power from a USB hub can cause the communication to drop immediately after the DA is sent. Hardware Mismatch
: A mismatch between the firmware's scatter file and the physical hardware of the phone can cause the tool to hang as it fails to verify the target device's internal layout. Strategic Solutions
To overcome this error, users should apply the following troubleshooting steps in order of complexity: Check Hardware Connections
Switch to a high-quality original USB cable and connect directly to a rear USB port on the PC motherboard rather than a front-panel port or hub.
Ensure the device is powered off completely. If the battery is removable, take it out and reinsert it before reconnecting. Verify and Update Drivers Reinstall the MediaTek USB VCOM drivers
and check the Windows Device Manager to ensure the device is recognized as "MediaTek Preloader" or "MTK USB Port" without any warning symbols. Software Adjustments Version Compatibility : Try using a different version of the SP Flash Tool
. Sometimes an older version (like v3.x) is required for legacy devices, while newer chips need v5.x or v6.x. DA File Selection : Manually select a compatible Download Agent (often MTK_AllInOne_DA.bin
) from the tool’s folder. If the device has a secured bootloader, a custom DA file specific to that model may be necessary. Device Key Combinations
Some MTK devices require specific keys to be held during connection to trigger the correct flashing mode. Common combinations include holding Volume Down , or both while plugging in the USB cable.
