Use this guide to remove the screen of the Huawei Honor 9.
Before disassembling your phone, 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.
This guide involves removing the rear glass cover and the battery—you will need replacement adhesive to reattach both and/or a new battery. If your replacement part does not come with adhesive, use a strong double-sided tape to secure it.
Heat an iOpener and apply it to the back of the phone for around two minutes. This will help soften the adhesive securing the rear glass.
You might need to reheat and reapply the iOpener several times during the rear glass removal.
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.
Secure a suction handle to the lower edge of the rear glass, as close to the edge as possible.
If the phone's rear glass is cracked, the suction cup may not stick. Try lifting it with strong tape, or superglue the suction cup in place and allow it to cure so you can proceed.
Lift the rear glass with the suction cup to create a gap between the glass and the frame.
Insert an opening pick into the gap.
Don't attempt to insert a pick between the back glass and the frame before creating a gap. The glass is covered with foil from the inside, and by not creating a gap, you risk inserting the pick between the glass and the foil instead, which would permanently damage the foil and ruin the solid color of the back panel.
If you have trouble, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.
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.
Apply an iOpener to the center of the display, to loosen the adhesive beneath the battery.
The adhesive beneath the battery is very strong. You might need to repeat this process during the removal procedure several times. If heat does not work you can apply isopropyl alcohol (90+%) to the corners of the battery and let it penetrate the adhesive for several minutes before continuing.
The flex cables under the battery are laid out as seen in the image. Try to avoid prying in the marked areas to prevent damaging the cables.
Try your best not to deform the battery during the following removal process. Soft-shell lithium-ion batteries can leak dangerous chemicals, catch fire, or even explode if damaged. Do not use excessive force or pry at the battery with metal tools.
Insert the flat end of a spudger at the top right corner of the battery where the flex cable is located and start to pry the battery up.
Work your way down the right side of the battery and loosen the adhesive with the spudger.
Do not reuse the battery after it has been removed, as doing so is a potential safety hazard. Replace it with a new battery.
Remove any remaining adhesive from the phone and clean the glued areas with isopropyl alcohol and a lint-free cloth before installing the new battery.
If possible, turn on your phone and test your repair before installing new adhesive and resealing the phone.
Secure the new battery with pre-cut adhesive or double-sided adhesive tape. In order to position it correctly, apply the new adhesive into the phone at the places where the old adhesive was located, not directly onto the battery. Press the new battery firmly into place.
Apply a heated iOpener to the display for around two minutes to soften the adhesive underneath.
You might need to reheat and reapply the iOpener several times during the removal procedure to get the adhesive warm enough to cut. Follow the iOpener instructions to avoid overheating.
Once the screen is warm to the touch, apply a suction cup near the top edge of the phone right under the earpiece speaker.
If the phone's screen is cracked, the suction cup may not stick. Try lifting it with strong tape, or superglue the suction cup in place and allow it to cure so you can proceed.
Pull up on the suction cup and insert the tip of an opening pick under the display near the earpiece speaker.
Slide the opening pick to the top left corner of the phone to cut the adhesive.
Remove any remaining adhesive from the midframe, and clean the glued areas with isopropyl alcohol and a lint-free cloth.
If possible, turn on your phone and test your repair before installing new adhesive and resealing the phone.
The best way to secure the new screen is with a sheet of custom-cut double-sided tape, but high bond double-sided tape will also work. Apply the tape to the back of the screen, then carefully feed the display cable through the frame. Align the screen with the frame and press it into place.
