How can I open up a screen?

Hi hello greetings

Um... i have an ipad pro 9.7 model,

and i tried to open up a screen,

But I have a problem with applying a heat.

I used iopener kit which i bought from here

And hair dryer.. With suction cup.

People says if it works, then the screen will pop up little bit, disabled tape or whatever

But Nothing happens.. I can't put a pick or card. I can't put anything..

All i got is burning hot screen. What am i supposed to do...?

How am i meant to open this?? This is not easy at all..
