Before you begin
This guide shows how to remove and replace the logic board for your iPhone 16 Pro Max. The logic board has connectors on its top and bottom, so you may need to remove the screen to complete the repair. This procedure will attempt to connect the logic board without removing the screen first. If you remove the screen, you'll also need screen adhesive. You'll need replacement back glass adhesive to complete this repair. After your repair, calibrate authentic Apple replacement components using Repair Assistant.
