  • Use tweezers to peel away any remaining adhesive from the phone’s chassis. Then clean the adhesion areas with high concentration isopropyl alcohol (at least 90%) and a lint-free cloth to prep the surface for the new adhesive.
  • Turn on your phone and test your repair before installing new adhesive and resealing the phone.
  • Carefully apply the new adhesive to the back cover, then line up one edge of the glass against the phone chassis and firmly press the glass into the phone.

Make sure you transfer over the vibration motor if the new frame does not have it… didn’t realize my replacement didn’t have it until I put the glass back on :/

Is it just me or is this guide not complete?

Nils Hennings - Jun 29, 2021

The guide assumes that you have a new display unit containing all the parts that are left after the last step (display, front glass, screen, cooling system, vibration motor and so on.)

Sam Omiotek - Jun 29, 2021

Since replacement parts vary from seller to seller, you’ll have to compare yours to the original and transfer any remaining components. This guide was written for the display assembly that we were selling at the time.

When transferring other components such as the vibration motor just be sure to use the same methods as with similar components. Work slowly, always use heat or ≥90% isopropyl alcohol to soften adhesives, and search the internet for more information as necessary.
