Introduzione
Use this guide to replace the daughterboard in your OnePlus 9 5G.
You'll need replacement adhesive for the rear glass in order to complete this repair.
Note: Retaining water resistance after the repair depends on how clean the mating surfaces are and how accurately the adhesive is reapplied. Your device will lose its factory-given IP (Ingress Protection) rating, however, only the T-Mobile versions of the OnePlus 9 5G offer an IP rating.
