Before installing a new display, it's very important to remove all traces of the old adhesive from the frame, while taking special care to remove any small glass fragments.

After removing all traces of glue and glass from the frame, clean the adhesion areas with 90% (or higher) isopropyl alcohol and a lint-free cloth or coffee filter. Swipe in one direction only, not back and forth.

This helps remove any remaining adhesive residue and preps the surface for the new display.

If the frame is bent, or if any glue or glass remnants are left behind, the new display will not mount correctly and may be damaged.
