    Hello,

    I had not seen that particular video until now and it does seem to work at bringing a dead P01 or P59 PCM back from the dead. But there are easier ways and other videos that show that only a certain pin on the board needs to be grounded. This allows a small "kernal" of a program to load for recovery which seems to be what the guy in the video link did. Basically, after grounding that pin, you have a few seconds to get that kernal loaded.
