How much time and how many times did you guys left the iOpener on it before the first try with the prying tool?

Thats a very good question. I think dust might have entered from the diopter adjustment wheel gap. There doesnt seem to be anything stopping that from reaching the front outside part of the viewfinder.

Have you tried compressed air or blowers right in that same gap? Might make the dust spec move.

Sam Lionheart, thank you so much for replying to my concerns abou the iOpener and the screen. However I only asked about how many passes it took because I have to do the inverse. I need the adhesive soft enough so it adheres back to the screen again, so I won't find resistance to know when it's worm enough/already cool. All I'm going to do is put some weight over it. Would say that 1 pass would be enough to heat the adhesive enough on only one edge of the screen?

Is the iOpener now the preferred tool for opening up Surface devices? Because over at the Surface Pro 3 guides, iFixit mentions that a heat gun would be better. Also, how many iOpener passes does it take for the adhesive to melt and the screen to lift easily like that?

iFixit folks, does the old adhesive still work for re-attaching the screen back or you have to put glue or replace the all the adhesive strips entirely?

Will the iOpener damage the lcd/ pixels or even the camera/sensor if placed on the edge above those?

I need to soften up the adhesive only, not replacing the screen at all.
