The pictures don't really do justice to how hard it is to pop the focal cap off. One actually has to pull pretty hard, I was afraid of breaking something, but it all worked out.

I've seen 5 guides say that the lens adjustment cover just pulls straight out, but even with significant force, it doesn't budge. Are there two different versions of the HD20 with two different designs for the cover?

I couldn't get the shroud off until I had the plastic top of the projector mostly off.

The shroud has clips on it that attach to some bolts coming off the lense so yeah, it will take some force to pop the clips.
