Introduction

This guide is for removing the motherboard of the Xperia XA Ultra. To complete this disassembly, you will need a T3 and T5 Torx screwdriver as well as a plastic spudger to pry open certain parts of the phone. A hairdryer or any other device that can supply heat is recommended to loosen the glue holding the components together, although it is possible to complete the replacement without.

Carefully remove the back panel of the phone with a plastic spudger, or other flat and thin wedge tool. Work your way around the perimeter of the case, loosening and prying gently, until there is sufficient distance between the panel and phone.
