If you have forgotten your original Apple ID credentials, or if you purchased a secondhand device that is still linked to a previous owner's account, you will find yourself locked out. This comprehensive guide details the technical realities, step-by-step methods, and alternative strategies available for bypassing the iOS 9.3.5 Activation Lock on an iPhone 4S. Understanding iCloud Activation Lock on Legacy iOS iphone 4s activation lock bypass ios 9.3.5
💡 While stories of bypassing are common in tech circles, Apple’s Activation Lock is a powerful anti-theft tool. For real-world devices, the only permanent and fully functional solution is using the original Apple ID or providing proof of purchase to Apple Support.
As of 2026, bypassing activation lock on an iPhone 4S (A5 Chip) running iOS 9.3.5 is entirely possible. This guide covers the most effective, tested methods to get your device back up and running. What is iPhone 4S Activation Lock?
Bypassing the Activation Lock on an iPhone 4s running iOS 9.3.5 is technically possible but remains complex due to the hardware limitations of the A5 chip. Standard modern tools like Checkra1n do not support the iPhone 4s as they require at least an A7 chip. The iPhone 4s running iOS 9
For a more permanent solution, several software tools have been developed specifically for the iPhone 4S's A5 chip. These methods provide full or near-full functionality.
The remains a nostalgic piece of hardware, but many users pulling it out of storage run directly into a roadblock: the iCloud Activation Lock .

For years, the consensus was that bypassing this lock on iOS 9.3.5 was impossible without the original password. While tools existed for older devices (like the iPhone 4, which had hardware exploits via the limera1n bootrom vulnerability), the iPhone 4S utilized a different, more secure processor architecture (the A5 chip). This left technicians and recyclers with piles of perfectly functional glass and metal that were functionally worthless.
Unplug the iPhone from the Arduino and immediately connect it to your Mac. Open a specialized legacy bypass utility like Sliver .
