Yes, I see you posted over there and I am sure your efforts will be appreciated.
Actually I have never downgraded a Lion computer to Snow Leopard; I actually own only one: the 2011 Mac Mini. As you know, I have instead chosen to become proficient in utilizing Rosetta by means of virtualization in Parallels.
My mind is much too cluttered as it is and attempting to remember how to downgrade to SL would only serve to clutter it more, needlessly, in my case.
Unfortunately for me, I came across this Albert Einstein parable, much too late in life for me: He would never memorize anything that he could look up, because it took up too much valuable brain space!
So it is just easier for me to remember that you are the Emperor of all Things Revertible to Snow Leopard!
NOTE: Actually you responded to the wrong guy, but your information was helpful, just the same!
