Is there a way to teardown for screen replacement with out the use of heat gun to unstick qlue
hairdryer works as well as a hot air gun or these guys sell a microwavable sack thing that you microwave and is designed for resting on the screen to melt the glue i think its called an iopener, but really you just need some heat to soften the glue a hot water bottle would work just as well as long as you make sure its dry
Any gentle, non-focused heat source should be fine. A hairdryer, space heater or radiator will all work. Just be careful to not get it TOO hot, otherwise you could damage the motherboard or LCD.
