No.
When I first went on to CFW 1.03.06, I looped around a bit between non CF and CF using the non CF 1.03.06, although this wasn't suppose to be necessary. Powering down and back up might also be useful. Your'll see that Black Hole says remove all CF etc, but you can get away without doing that. Yes, so I'd downgrade to 1.03.06 not the CF that af123 generated, then upgrade to the CF. Not forgetting to put the disables in and the time blocking back in once finished else you will get the non CF re-installed over the air again.
