Yet another issue replacing the TH board

trying to get the damn cable chain off and the rest of it departed leaving the last link stuck in the plastic piece in front to the buffer block. I have it twisted out at about a 45 deg angle but I’m genuinely afraid of breaking something. Don’t really want to tug on the cables any more than I am already. Tried slipping a screwdriver behind it and prying - which is what got it to 45 deg.

What are the secrets here? The little video clip in the wiki shows the guy doing it easily - I bet those pins have been “massaged “ to make it release like that.
