    • Use a Spudger to slightly lift up the motherboard.

    • Take especially care of the two black connectors on the side of the battery. They break off easily during the removal of the motherboard.

    • Use a tweezer to take out the vibration motor and then remove the motherboard completely.

Where do I need the Back Cover Adhesive Strips for?

Visser - Réponse

The guide doesn’t mention that one needs new adhesive for the battery (the one I bought isn’t sold with it). It would therefore be wise to mention what kind of adhesive (two-sided, what thckness, etc.)

axel - Réponse

Double sided tape is enough to keep it in place, as the back cover and midframe holds everything down for extra reinforcement. Sony sure makes their smartphones !&&* to repair, but that’s another rant.
