    • You will need to pry the screen up to remove it from the phone. Read the following notes carefully before proceeding.

    • Take note of the two seams on the edge of the phone:

    • Screen seam: This seam separates the screen from the rest of the phone. This is where you should pry.

    • Frame seam: This is where the plastic frame meets the back cover. It is held in place by screws. Do not pry at this seam.

    • Before you begin, note the following areas on the screen:

    • Screen flex cable: Do not insert the opening pick deeper than instructed or you risk damaging this cable.

    • Note the orange ribbon cable under the lower-right corner of the screen, which is susceptible to damage if your opening pick is pressed into it. Only insert your opening pick as little as is necessary to separate the screen adhesive.

    • Adhesive perimeter: Prying beyond this narrow perimeter without angling the pick will damage the OLED panel.

  3. Google Pixel 4a Back Cover Replacement, Heat the right edge of the screen: step 3, image 1 of 1
    • Apply a heated iOpener to the right edge of the display for one minute to soften the adhesive.

    • 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.

    • If your display is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction cup. If all else fails, you can superglue the suction cup to the broken screen.

    • Place a suction cup as close to the right edge of the screen as possible.

    • Lift the suction cup with a strong steady force.

    • Insert the tip of an opening pick into the screen seam no more than 1 mm.

    • This step shows how to insert the pick without damaging the OLED panel. Do this before beginning to slice the adhesive.

    • With the pick 1 mm into the gap, pivot the pick upwards to a steep angle.

    • At a steep angle, carefully push the pick into the gap about 1/4 inch (6 mm). The pick should slide in below the OLED panel.

    • Stop if you feel the point of the pick hitting a ridge. The pick may be pressing against the edge of the OLED panel. Angle the pick and try again.

  6. Google Pixel 4a Back Cover Replacement, Cut the adhesive: step 6, image 1 of 3 Google Pixel 4a Back Cover Replacement, Cut the adhesive: step 6, image 2 of 3 Google Pixel 4a Back Cover Replacement, Cut the adhesive: step 6, image 3 of 3
    • Slide the pick along the right edge of the screen to cut the adhesive.

    • Do not insert the pick more than 1/4 inch (6 mm) or you may damage the screen's flex cable.

    • Leave the pick in the top right corner to prevent the adhesive from re-sealing.

    • The screen adhesive is very weak and you should not need to re-apply heat. If the screen does feel hard to slice, apply heat to the difficult area for one minute and try again.

    • Insert another opening pick into the right edge of the phone at an angle where a gap has already formed to prevent damage to the OLED panel.

    • Slide the opening pick around the bottom of the phone to cut the adhesive.

    • There is a delicate cable under the bottom-right corner of the screen. If you feel your opening pick snag on anything, pull it out and try again. Make sure your pick is angled downward and only inserted as little as is necessary to separate the adhesive (no more than 2 mm deep).

    • Leave the pick inserted along the bottom edge to prevent the adhesive from resealing.

    • Insert another opening pick into the bottom edge of the phone at an angle where a gap has already formed to prevent damage to the OLED panel.

    • Use the pick to slice through the left edge of the phone.

    • If the screen feels hard to slice, heat the left edge for one minute and try again.

    • Leave the pick inserted along the left edge of the phone to prevent the adhesive from re-sealing.

    • There's a mesh covering the earpiece speaker on the top edge of the screen. If you don’t have a replacement mesh, take care not to damage or lose this component.

    • Insert another opening pick into the left edge of the phone at an angle where a gap has already formed to prevent damage to the OLED panel.

    • Slide the pick around the top edge of the phone to cut the adhesive.

    • If the screen feels hard to slice, heat the top edge for one minute and try again.

    • Once you have cut around the perimeter of the phone, carefully lift the right edge of the screen, opening the phone like a book.

    • Do not remove the screen yet.

    • Use an opening pick to carefully cut through any remaining adhesive.

    • Remove the screen.

    • To install a new screen:

    • Check if your replacement screen has speaker mesh and top edge adhesive pre-installed.

    • If it does, you won't need the top edge adhesive.

    • If it doesn't, remove the larger clear liner from the top edge adhesive and apply it to the screen (not the frame). Make sure the larger cutout lines up with the speaker mesh.

    • Follow this guide to apply the custom-cut adhesive.

    • Use the third photo as a reference to position your adhesives.

    • During the boot-up process after reassembly, the screen will go through a calibration sequence. Don't touch the screen during this process, as it could result in improper touch calibration and create touch issues.

T3 driver is too small. T4 driver fits all screws perfectly.

(T3 worked for me)

The back cover I bought didn't include the sensors (fingerprint and camera flash) and a grommet thing over one of the speaker holes, that are attached to the back cover. So I had to transfer those pieces myself. I needed to use heat from the iOpener to soften glue that was holding them on to the old back. The replacement back seemed to have replacement glue in place under peel tape. I didn't replace the glue holding the screen, instead heated everything up with the iOpener when replacing the screen in the hope that the old glue will still work, fingers crossed.

I suggest following this other guide instead, to replace the fingerprint sensor, is the same with two extra steps (but still need to swap the flash and ‘speaker grommet thingy' as well as the fingerprint sensor):
