*Description*
If your iPhone 17 Pro is stuck in a boot loop, keeps restarting with panic logs, shows No Service or a missing IMEI, has Wi-Fi/Bluetooth greyed out, or is completely dead, the issue is often on the logic board (motherboard). In this HowFixit guide, I’ll show you how to replace the iPhone 17 Pro logic board step by step, then calibrate paired parts using Repair Assistant so the phone activates and works correctly.
You’ll learn safe screen removal, full connector disconnect, camera/speaker/Face ID handling, and correct reassembly order. After the swap, we walk through Settings → General → About → Parts & Service History to complete calibration for the battery, cameras, Face ID, and display. Finally, we restore sealing by cleaning the frame and applying new waterproof adhesive tape to help bring back water resistance.
