Introduction

For your safety, discharge the battery below 25% before disassembling your phone. This reduces the risk of fire if the battery is accidentally damaged during the repair. If your battery is swollen, take appropriate precautions.

You’ll need replacement adhesive in order to complete this repair.

What you need

Step 1

              Loosen the rear glass
  • Prepare an iOpener and apply it to the rear glass for at least three 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.

Step 2

              Insert an iFlex
  • Due to its surface, no suction tool will hold onto the phone’s rear glass. A thin slicing tool is required to create a gap between the rear glass and the midframe.
  • Insert an iFlex into the seam between the rear glass and the midframe at the bottom edge of the phone to create a gap. This may require some force.
  • Leave the iFlex in place to prevent the adhesive from resealing.
