Allow your phone's battery to fully drain before starting repairs. A charged battery may catch fire if damaged during the repair.

Unplug any cables and fully shut down your phone.

Prepare an iOpener and apply it to the rear glass for two minutes to loosen the adhesive underneath.

A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the display and internal battery are both susceptible to heat damage.
