The first step is the LCD screen removal from the front.

edges until the pasted adhesive becomes soft.

on the heating pad. Select the mobile phone heating option and leave it till
it completes. Alternatively, you can use a heat gun or hairdryer.
Once you feel the Heating is enough, use a suction cup to lift the screen a little and insert a
plastic card pry tool or something similar to cut the adhesive around the LCD screen.
