Reason people have made the PCM into a brick is for whatever reason the session is broken during or right after flashing leaves he flash memory in a non complete state or the data no longer matches the CRC checksum the PCM no longer has a valid segment 1 software.
Really? Can you damage the PCM because of a programming mistake?
Is there a procedure to save the situation when something happens during programming? For example when the HD has a crash or the laptop battery is down?
