^Sorry man. I've never had problems removing it. You've got me scratching my head now and questioning my writeup for the Avin...

Where did you get to? Are you stuck on dropping the sonic module in the back? Or the whole thing? After you get the sonic module out it should be cake. For S's and G's remove all 4 screws and see if it comes down easily? I remember it just falling down after removing the requisite 2 screws.
