To update the RM-820, you must perform a step marked differently than in the tutorial.
After step 11, DO NOT wait until you see the screen "lost connection", after pressing START, connect your phone inmediatly while hold "Volume Down", if necessary try several times until you see the word "rebooting" in NSC, hold button, you will notice that it does not detect your product code, that's the sign that we were successful.
When the phone show "!" release the button and its ready.
Sorry for my bad English, I do my best to help
