Use a heating tool such as an iOpener or Heat gun around the edges of the Amazon Fire's glass screen. The iOpener may take longer to use. However, a heat gun can warp the plastic if used incorrectly.

As you heat the edges, use a separator tool such as a guitar pick to lift the glass panel up and hold it up as you work around the device.

Do not use a separation tool on the top edge of the device where the front camera would be; the digitizer cable is located in this location and can easily be severed. Instead, work in a U shape until you have 3 sides lifted from the frame

Be patient with this step because it can be very time consuming and remember to use proper safety gear when using a heating device.
