Place your screen into the new shell and affix the bezel into position; the ribbon cable should slide through the gap like before.

The case should click into place so that it stays together even without screws. There also may be a small gap between the top and bottom case, as this common on third party cases.

Reinstall the five Tri-point Y00 screws around the screen.

Reinstall the speaker, buttons, and silicone pads into the bottom case.
