One way to know for sure is after hooking up FlashScan, watch the orange LED second from the right. If it blinks rapidly (4 times per second) all the time, then the PCM is in dead-poll and should be recoverable. That contsant blinking is the PCM "asking" any connected tool for a new calibration. If it blinks just a few times and then stops then it is bricked, in that case the initial burst of blinking is attempting to contact the PCM.
