In this second part of our iPhone 12 Pro boot loop repair series, we continue troubleshooting the issue after identifying a potential fault with the Audio IC, which unfortunately didn’t resolve the problem. Our investigation led us to another possible culprit—the CATI EEPROM Chip. In this video, we’ll guide you through diagnosing this new issue and outline the next steps, including ordering the replacement part. Stay tuned for Part 3, where we’ll perform the actual repair and work to bring the iPhone back to life!
