Use a heat gun to lightly heat the edges of the back to soften the adhesive that connects the back cover to the rest of the frame.
Using a heat gun, hair dryer, or hot plate will make the metal frame rather hot to the touch, so handle it with care.
Be careful not to overheat the device –the OLED display, battery and other internal parts can be damaged by excessive heat. Approximately one minute should be enough to soften the adhesive.
An iFixit iOpener, hairdryer, or hot plate can also be used to heat the edges. See the iOpener Heating guide for instructions on using the iOpener.
