Introduction

Use this guide to replace a broken rear glass on your Huawei P8 Lite (2017).

You’ll need replacement adhesive to reattach components when reassembling the device.

  1. Huawei P8 Lite (2017) Rear Glass Replacement, Apply a heated iOpener: étape 1, image 1 de 1
    • Heat an iOpener and apply it to the rear glass for two minutes.

    • A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the P8 Lite—the display and internal battery are both susceptible to heat damage.

    • Apply a suction cup to the rear glass, as close to the right edge as possible.

    • If the phone's 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.

    • Pull up on the suction up with strong, steady force to create a gap.

    • Depending on the age of your device, this may be difficult. If you have trouble, apply more heat to further soften the adhesive and try again.

    • Insert the tip of an opening pick into the gap between the rear glass and frame.

Conclusion

Secure the new rear glass with pre-cut adhesive or double-sided adhesive tape.

To reassemble your device, follow these instructions in reverse order. Apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).

Compare your new rear glass to the original part. You may need to transfer the fingerprint sensor or remove adhesive backings from the new part before installing.
