Logs related to DA (Download Agent) initialization.
It allows advanced users to identify exactly which partition transfer caused a failure.
Master Guide to Smartphone Flash Tool "Runtime Trace Mode" The Smartphone Flash Tool (SP Flash Tool) is the definitive software for servicing MediaTek (MTK) Android devices. Among its advanced diagnostic features, is one of the most critical yet misunderstood settings. This guide provides an exhaustive breakdown of what Runtime Trace Mode does, why it is essential for troubleshooting, and how to use it safely. What is Runtime Trace Mode?
: A highly-rated, browser-based tool direct from Google for Pixel devices. While it doesn't use the exact phrase "runtime trace mode," it provides real-time status updates and automatic driver handling, which Reddit reviewers praise for being much faster and more reliable than manual fastboot commands. smartphone flash tool -runtime trace mode-
It displays detailed logs of the communication between the tool and your device.
Encounters specific errors that regular logs don't fully explain.
To utilize Runtime Trace Mode during a firmware update, users typically follow these steps: Logs related to DA (Download Agent) initialization
is a specialized interface of the SP Flash Tool—primarily used for MediaTek (MTK) Android devices—that provides detailed real-time monitoring of the flashing process. What is Runtime Trace Mode?
Furthermore, this mode is indispensable for diagnosing "Secure Boot" errors. Modern smartphones employ strict security measures to prevent unauthorized software from being loaded. If a flash tool encounters a security mismatch, the trace log will reveal the specific authentication failure. This allows developers to identify whether the issue stems from a corrupted firmware file, a mismatched bootloader version, or a hardware-level security fuse that has been blown.

When a phone has a physically degraded memory chip (eMMC or UFS), it may drop its connection mid-flash. The trace log will catch the exact sector block address where the write command timed out, confirming a physical hardware failure rather than a software issue. How to Enable Runtime Trace Mode in SP Flash Tool Follow these steps to activate and utilize the trace logs:
MediaTek utilizes Secure Boot on modern chipsets (such as the Dimensity series). To flash these devices, developers must use modified or authorized Download Agents ( DA_67xx.bin , etc.) to bypass security checks. If a custom DA hangs during execution, Runtime Trace Mode reveals the exact memory address where the handshake failed. 3. Resolving Dynamic Partition Errors
: Look for the checkbox labeled Runtime Trace Mode (or simply Trace depending on your SP Flash Tool version version v5 vs v6). Check this box.
The primary goal of Runtime Trace Mode is to transform an opaque flashing process into one that is transparent and traceable. It answers crucial questions such as:
