I've a good solder sucker and it seems to have removed the solder from the underside of the chips. However when I look at the top side there still seems a lot of solder caked around the pins. Which probably explains why the chip still won't budge.
So my question is, how do you remove the solder which is applied to the pins on the top side of the board?

Normally you cover the parts of plastic and use a heat gun.
If the chip got legs you can cut them if you are going to replace the chip.
Other method without heat gun is to put a lot of solder on both sides of the chip and use 2 soldering irons to heat up both sides or be very fast with one iron + push the chip up with a tool.
