Rather than trying to explain, I made a quick 2 min video about how I solved it:

Excuse the rambling.
Edit: I partly agree with admcmei86 on the theory on why the bug happens. I think it has something to do with when you sabotage the modules, but it seems to be a location trigger as well.
Edit 2: People say that you can get into the room through a window, but the window to the bottom room have crates covering the window. At least for me.
Replying to your EDIT 2: The lower room has two windows. If you're facing the non-functional door to the top room, then that lower-room window with the crates is below you and to your left. You want to go in the one below you and to your right, directly opposite the window you tried to go in. If you climb about halfway up the stairs to the upper room and stop on the landing before the stairs turn left, you'll see the window right in front of you.
I can't tell now if this part is bugged or not, because the doors never did open up for me but the quest completed just fine as soon as I went in the window and accessed the Kett terminal for the first contact logs. Do we know for sure that the doors are even supposed to open? Seems odd that you'd be able to shoot out the windows and work around the doors if the point was to unlock the door. Maybe disabling the security matrix just unlocks the terminal and we were always supposed to go through the window?
