Hello, I'm having exactly the same problem you had. I want to turn off my a2sd, without losing my applications. I've seen your steps, but I don't understand what you did, or what tool did you use, in the first point:
Could you please help me?
go to settings then select manage applications, then select each app and there should be an option "move to phone" or "move to internal storage" for every app moved to the sdcard, just go through your apps list and check each one
