(SX034QT) How the heck does the motherboard come out of this thing?

Got the digitizer off and the back off. I need to remove the mobo for cleaning. I found and removed four screws and the camera but I cannot get the motherboard out. It feels like there’s another screw or perhaps some adhesive but I’m already putting more pressure on the mobo than I’m comfortable with and it’s not budging at all. The top-right side (as seen in the pic below) lifts up off the frame about a centimeter, but the top-left side lifts barely a millimeter. What’s the secret?

If anyone is looking for this answer: The motherboard is held on with a bit of adhesive. It’s probably possible to remove the LCD, heat the plastic from behind, and loosen the it that way. It may also be possible to heat the motherboard enough without distorting the plastic frame.

I chose to disconnect the battery, put a plastic spudger between the motherboard and the frame, twist the spudger to lift it about a half centimeter, then sprayed a bit of 99% isopropyl between the motherboard and the frame at the point of the adhesive. (In the picture below, the adhesive point is at the upper-right corner of the motherboard, just below the “notch”.) After about 30 seconds I applied a bit more force to the spudger and, with a somewhat scary “pop” sound, the motherboard released from the adhesive none the worse for wear.

Heat works, I heated the motherboard below the notch at 120 degrees C (could go lower) and the board peeled right up.
