For smaller devices, thread a heated iOpener through the arms of the Anti-Clamp to heat your device.

For larger devices, or iPhone models 12 and newer, use a hair dryer or a heat gun to soften the adhesive along your starting edge.

iPhone models 12 and newer have a tougher adhesive that the iOpener is less effective at opening than a hair dryer or heat gun.

Be careful not to overheat your device. The edge should feel slightly too hot to touch.
