The implementation varies significantly by chipset vendor. Here is a vendor-specific breakdown.
Set the logging level to "Debug" or "Runtime" to generate the trace files. After the attempt, logs are usually saved in the sub-folder within the SP Flash Tool directory. For most users, this mode should remain smartphone flash tool -runtime trace mode-
When a phone is "hard-bricked," its primary operating system is gone, and it cannot boot past a black screen. In this state, the phone relies entirely on its hardcoded Boot ROM to communicate. If the SP Flash Tool repeatedly disconnects or fails immediately upon plugging in the USB cable, Runtime Trace Mode will show if the Boot ROM is rejecting the connection due to signature mismatches or hardware faults. 2. Identifying Defective Hardware (EMMC/UFS Failure) The implementation varies significantly by chipset vendor
| Feature | Normal Flash Mode | Runtime Trace Mode | |---------|------------------|----------------------| | Logging during flash | ❌ No or very limited | ✅ Full streaming | | Boot failure analysis | ❌ Only final status | ✅ Pinpoint which phase failed | | Hardware register access | ❌ Not available | ✅ Yes (for supported chips) | | User needs | Any technician | Advanced repair / engineering | After the attempt, logs are usually saved in
While powerful, enabling trace mode often reveals sensitive information, including and secure boot data .
The most frequently documented method uses the combination. After launching the SP Flash Tool, simply press these keys simultaneously. One user guide instructs: "How to obtain the tool logs? 1. Run the tool; 2. Press Ctrl+Alt+t (Tool Title Hint: Runtime Trace Mode)". When activated correctly, the application window title may change or add an indicator such as "(Runtime Trace Mode)" – this visual confirmation is referenced in various tutorials. A flashing guide on Paragram.id explains: "Klik kanan 'Run as administrator sampai muncul tampilan windows 'Smart Phone Flash Tool (Runtime Trace Mode)'". Other sources mention a similar experience: "Now it will open a dialogue box named Smart Phone Flash Tool (Runtime Trace Mode)".
