Samsung Galaxy s2 help

[admin_exported]

I recently cracked my screen, i bought a new lcd screen and digitaliser. I have learn't how to replace the screen and get it working. However there is one screw I can not get undone which will result in the motherboard being removed. I was wondering if anyone knew if I can heat the screen adn continue with replacement of the screen with the motherboard still attached to the phone?
