Use this guide to remove or replace a faulty logic board in your iPhone 7 Plus.
It's important to note that each iPhone's logic board and Touch ID fingerprint sensor are paired at the factory, so replacing the logic board will disable Touch ID unless you also install a replacement home button that has been properly paired to your new logic board.
