I didn't want to use knife, I run the risk of slipping and cutting trace or my fingers. My smallest wire cutter can't quite fit in there and when I tried the video trick above, the clip melted all the solder but the chip wouldn't budge even with force. I ended up doing the dentist pick trick, heated and lifted one pin at a time. When all 24 pins were lifted, it still wouldn't come off.
I ended up tapping the screwdriver and it finally popped off, someone used quite a bit of glue to hold the chip down. I cleaned the excess solder. and checking under magnifying glass and my meter all 24 pins are still intact and still connected so no trace was severed or pad lifted. I still have to clean up flux and install the new chip.
