Understanding Smartphone Flash Tool Runtime Trace Mode: A Comprehensive Guide

If you are troubleshooting a stubborn "brick" or a persistent error, follow these steps to enable the log:

1. Use a stable computer: Ensure your computer is stable and not experiencing any hardware or software issues that could affect the flashing process.
2. Use a genuine USB cable: Use a genuine USB cable to connect your device to the computer to prevent connectivity issues.
3. Monitor the logs: Closely monitor the logs and output during the flashing process to identify any potential issues.
4. Be cautious with settings: Be careful when adjusting settings or making changes to the flashing process, as incorrect configurations can lead to device damage or data loss.

• Boot-loop after firmware upgrade – Trace shows which daemon crashes.
• Dead after flashing wrong preloader – Traces from BROM reveal why handshake fails.
• Random reboots – Kernel panic logs captured before reboot.
• Firmware customization – Ensure custom boot images initialize correctly.
• EMMC / UFS replacement – Verify storage timing and partition mounting.

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"). smartphone flash tool -runtime trace mode-
