Lay the iOpener flat on the edge of the device, over an adhesive seal you wish to heat. Smooth the iOpener along the surface to ensure good contact with the device.

Let the bag sit on the device for approximately 90 seconds before attempting to open the front panel.

At this point you should be able to begin prying under the screen with a plastic opening tool. Be sure to see your device's specific guide for where and how to do this.

Throughout the procedure you may need to reheat the iOpener. To prevent overheating the iOpener, always wait at least two minutes before microwaving again. Do not microwave the iOpener for more than one minute at a time.
