Use this guide to replace a cracked rear glass of the Huawei P20 Pro.

Opening the Huawei P20 Pro will damage the waterproof sealing on the device. If you do not replace the adhesive seals, your phone will function normally but will lose its water-protection.

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

  1. Switch off your phone.
    • Switch off your phone.

    • Use an iOpener to loosen the adhesive beneath the rear glass. Apply the iOpener for at least two minutes. You might want to repeat this step several times during the back cover removal.

    • The adhesive of the Huawei P20 Pro is of moderate strength, however a hair dryer, heat gun, or hot plate may also be used if you aren't able to open the device with the iOpener. Be careful not to overheat the phone—the OLED display and internal battery are both susceptible to heat damage.

  2. If the phone's rear glass is cracked, a suction cup may not stick very well. Try lifting it with strong tape, or superglue the suction cup in place and allow it to cure so you can proceed. Press a suction cup onto the rear glass close to the bottom edge of the phone. Lift the bottom edge with the suction cup, opening a slight gap between the rear glass and the frame.

    • Press a suction cup onto the rear glass close to the bottom edge of the phone.

    • Lift the bottom edge with the suction cup, opening a slight gap between the rear glass and the frame.

    • Insert an opening pick in the gap and slide it to the bottom right corner. Leave it there to prevent the adhesive from resealing.

    if the back cover is not broken, i’d suggest NOT to use an opening pick as if the phone was not heated enough, you may crack the glass on the edges. better use the iPlastix, it is thinner and less stressful for the glass.

    It is better to put a peak on the side because the side opens first than the bottom of the phone.

    I have to agree that is is much easier to start opening from the side. Do read the rest of the guide though, to make sure you won’t hit something when opening it from the side.

  6. Insert a fifth opening pick at the top right corner of the rear glass. Slide the opening pick along the right edge of the phone to cut the remaining adhesive. Don't open the phone all the way yet. The proximity sensor flex cable is still connected to the motherboard.

To reassemble your device, follow these instructions in reverse order.

After installing the rear glass, apply strong, steady pressure to your phone for several minutes to help the adhesive form a good bond, such as by placing it under a stack of heavy books.

Do you suggest any particular kind of adhesive? I always have trouble with these things. Sooner or later, if not immediately, any glass or screen I fit this way always lifts up. The adhesives that come with the parts always seem weak. I try B-7000 glue or/and double sided tape, but still it won’t sit tight.

Smeargle - Yanıt

Hi Smeargle, the options you already tried are also the ones I’d recommend. When applying new double-sided adhesive I’d also suggest slightly heating the glued area and applying some pressure for a few hours (stack of heavy books overnight might do).

Hey how do you get the huawei sealed back?

For it to be waterproof again.

Léo Zakri - Yanıt

You either buy a rear glass with seal attached or buy a seal and do it yourself, not sure why the author didn't go over this…

Although I understand the steps, why did you not include steps to install the fresh rear glass?
