The identifier iPhone9,3 and board configuration D101AP refer specifically to the iPhone 7 (GSM model) . Error Analysis Device Identification : The target is an iPhone 7 (GSM).
This article provides a 2,500+ word definitive guide. We will explore the hardware identification system of Apple devices, the specific role of a “loader,” and step-by-step troubleshooting methods ranging from simple driver reinstalls to advanced NAND reprogramming.
Jailbreak tools like Checkra1n are highly sensitive to data transmission stability. A faulty, non-genuine, or damaged USB cable can interrupt the data flow when the tool tries to write the loader application to the device. This is often indicated by the jailbreak process getting stuck at a specific percentage or failing silently without installing the loader. After 8 seconds, release the button but continue
