It tracks the UART or USB high-speed switching during the transfer. How to Access Trace Logs

When a device enters a boot loop (constantly restarting), it may be due to a corrupted system partition or a hardware fault. Trace Mode can capture the kmsg (kernel message) or Preloader logs to identify the exact point of failure (e.g., "Mounting /data failed," "DDR initialization error").

A phone turns on but has inverted touch or a non-functioning camera after a flash. Using Runtime Trace Mode during the flash would have shown you that the tool encountered a minor checksum error on a user-data partition but was set to "Download Only" mode, meaning it skipped verifying that data segment. The logs would have alerted you to the error, prompting you to use "Firmware Upgrade" mode for a more thorough and compatible update.

Runtime Trace Mode in SP Flash Tool is a powerful feature that provides users with detailed insights into the flashing process. By enabling this mode, users can monitor the progress, identify potential issues, and troubleshoot problems more effectively. By following the best practices and guidelines outlined in this article, users can harness the full potential of Runtime Trace Mode and ensure a smooth and successful flashing experience. Whether you're a developer, a technician, or an enthusiast, understanding Runtime Trace Mode can help you work more efficiently and effectively with SP Flash Tool.

Determine if a flash failed due to faulty EMMC or NAND flash memory.

Here is an example snippet of a healthy initialization sequence in an MTK trace log:

If you are asking for help on forums, the Runtime Trace log provides crucial information to help others debug your issue. Conclusion

Before executing a test flash, clear out your previous log folders. This ensures you do not waste time reading data from a prior, unrelated session. A phone turns on but has inverted touch

For the average user performing a standard flash, Runtime Trace Mode may not be necessary. However, for repair technicians, developers, and power users who frequently work with multiple device models or custom ROMs, this feature is indispensable. The ability to capture a complete trace of the tool’s execution transforms the flashing process from blind trial-and-error into a data-driven diagnostic exercise.

For standard, day-to-day firmware upgrades, Runtime Trace Mode is unnecessary and can safely remain turned off. However, it becomes an indispensable tool under specific circumstances: 1. Diagnosing Hard-Bricked Devices
