    • Using a plastic opening tool, gently pry around the perimeter of the device.

    • The ribbons behind the buttons and ports are very delicate. Make sure you do not run your plastic opening tool too deep into the bezel, as you could damage them.

    • Evenly heat the device in short intervals for about one minute.

    • Do not heat the device for more than 30 seconds at a time to prevent over-heating.

    You could also use the iOpener tool for this step. What is that the adhesive is holding in place?

    • If the board is too difficult to separate than more heating may be required.
