SP Flash Tool Stuck at Download DA 100%? Here’s the Ultimate Fix Guide

If you are reading this, you have likely been staring at your computer screen for the past 20 minutes, watching a progress bar refuse to budge. You are trying to flash a stock ROM, unbrick a Mediatek (MTK) Android device, or install a custom recovery. You loaded the scatter file, clicked "Download," connected your phone... and then it happened.

The SP Flash Tool log window displays: "Download DA 100%" ... and nothing else.

This is one of the most frustrating errors in the Android modding community. Fortunately, it is also one of the most fixable. This article will explain why this happens and provide ten proven solutions to get you past the 100% barrier.

Part 1: Understanding the "Download DA 100%" Error

Before smashing your keyboard, let's decode what "DA" means.

DA stands for Download Agent. Think of the DA as a small, temporary operating system that the SP Flash Tool uploads to your phone’s RAM. Its job is to take over from the phone's boot ROM and handle the actual writing of data (system, boot, recovery) to the flash memory.

The process flow is:

  1. SP Flash Tool sends the DA to the phone (0% to 100%).
  2. DA executes on the phone.
  3. DA negotiates the USB connection for high-speed data transfer.
  4. Flashing begins.

If you are stuck at "Download DA 100%," it means the SP Flash Tool successfully sent the DA file to the phone (Step 1 is complete), but the phone cannot execute the DA or cannot handshake back to the computer (Step 2 or 3 failed).

Step 2: Change USB Port & Cable

  • Switch to a USB 2.0 port (usually black plastic inside, not blue).
  • Use the original data cable that came with the phone.
  • Avoid USB hubs. Connect directly to the motherboard.
