A faulty logic board can also be replaced using the steps in this guide. 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.
You can also use this guide for reference to replace the logic board EMI shield stickers.
