Change the display on your iPhone 8 wholly by yourself. All you need is an iPhone 8 DIY LCD Glass Screen Repair Kit, and some time. Follow the instructions step by step, and you will soon be able to enjoy a working display again.

To get started turn your iPhone 8 completely to avoid damaging it during the repair. Press the Sleep/Wake button for about three seconds until the slider labeled "power off" appears. Swipe it from left to right and it's turned off.
2) Remove the enclosure screws
You will need a PL1 screwdriver to open iPhone 8. Remove the two pentalobe screws at the bottom of the enclosure. They are on the left/right side of the lightning connector.
3) Lift the display
To lift the panel you will need a suction cup, a hard plastic pick, and a heat gun, which you get in kit. Screen is glued to the frame, use a heat gun to heat the outer edges of the display to about 60°C (140°F).
Place the suction cup over the Home button or next to it. While lifting the screen with it, insert hard plastic pick between the aluminum frame and the display. Press down the aluminum frame and slide the pick all around the iPhone between the aluminum frame and the display frame. Try not to stick the pick in too far because that could damage the flexible flat display cables.
Use the pick to push the display so the tabs come out of the aluminum frame. Fold the display over to the side, and be careful not to stretch the flexible flat cables too much.
4) Disconnect from display
Use the Ph00 screwdriver to remove the four Philips screws. Take off the cover. Now carefully lift off the battery contact by inserting a plastic spatula below the connector.
