Introduction

If the frame is deformed, it’s important to replace it to make sure the new screen will mount correctly and won’t suffer damage from uneven pressure.

Due to the device’s design, you must remove the lithium-ion battery to access the display cables. If the battery was deformed during removal replace it with a new one—reusing a deformed battery is a potential safety hazard.

Before disassembling your device, discharge the battery below 25%. The battery can catch fire and/or explode if accidentally punctured, but the chances of that happening are much lower if discharged.

Note: This guide instructs you to replace only the screen while leaving the original frame and motherboard in place. However, some replacement screens for this phone come pre-installed in a new frame (a.k.a. chassis), which requires a very different procedure. Make sure you have the correct part before starting this guide.

Before you begin this procedure, be sure to have a set of replacement adhesives for both the back panel and the screen.

What you need

Step 1

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

Step 2

              Insert an opening pick
  • Secure a suction handle to the bottom edge of the rear glass, as close to the edge as possible.
  • If the rear glass is cracked, the suction handle may not stick. Try lifting it with strong tape, or superglue the suction handle in place and allow it to cure so you can proceed.
  • Lift the rear glass with the suction handle to create a small gap between the rear glass and the frame.
  • In case you have trouble creating a gap, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.
  • Insert an opening pick into the gap you created.
  • Slide the opening pick to the bottom right corner to slice the adhesive.
  • Leave the opening pick in place to prevent the adhesive from resealing.

Step 7

              Remove the rear glass
  • Carefully lift to rear glass upwards whilst pressing down the camera cover with a finger.
  • The camera cover and fingerprint assembly should separate from the rear glass during this procedure. In case the adhesive is too strong, you can apply a heated iOpener to the camera cover for one to two minutes to loosen its adhesive.
  • Remove the rear glass.
  • Apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).
  • Secure the new rear glass with pre-cut adhesive or double-sided adhesive tape. After installing the rear glass, apply strong, steady pressure to your phone for several minutes to help the adhesive form a good bond—a stack of heavy books works well.

  • Grab the first pull-tab with a pair of tweezers or your fingers and slowly pull it away from the battery and towards the bottom edge of your phone.
  • Pull hard enough to maintain tension on the strip, but don’t force it. Give it plenty of time to stretch and un-stick from under the battery.
  • Don’t press down on the battery. Hold the phone firmly by its sides.
  • Keep the strip flat and unwrinkled. Try to pull evenly on the whole strip, rather than pulling mainly in the middle or on one side.
  • Pull at a low angle so the strip doesn’t snag on the edge of the battery.
  • If the adhesive strip breaks off, try to retrieve it using your fingers or blunt tweezers, and continue pulling—but do not pry under the battery.
  • If the adhesive breaks off underneath the battery and can’t be retrieved, continue with the next step.

  • Follow the same procedure as with the previous strip: don’t press down on the battery, keep the strip flat and unwrinkled, and pull at a low angle.
  • If the adhesive breaks off underneath the battery and can’t be retrieved, apply a few drops of high concentration (over 90%) isopropyl alcohol under the edge of the battery in the area of the broken adhesive strip(s).
  • Wait about one minute for the alcohol solution to weaken the adhesive.
  • Use the flat end of a spudger to gently lift the battery.
  • Don’t try to forcefully lever the battery out. If needed, apply a few more drops of alcohol to further weaken the adhesive. Never deform or puncture the battery with your pry tool.
