The iPhone 4s remains a beloved piece of Apple history, but many users today find themselves stuck at the "Activation Lock" screen after a factory reset. This occurs because the device is still linked to a previous Apple ID. On iOS 9.3.6—the final update for the 4s—bypassing this lock requires specific techniques ranging from simple DNS redirects to hardware-assisted jailbreaks. Understanding the iCloud Activation Lock
The iPhone 4s holds a special place in tech history. It was the last iPhone Steve Jobs introduced, and it famously received an unprecedented of software updates. The final stop for this device was iOS 9.3.6 , a minor update released in 2019 specifically to fix GPS and timezone issues.
This must be soldered and stacked on top of the Arduino.
Often requires a jailbreak first (e.g., using Phoenix for iOS 9.3.6) to attempt a bypass, though it may result in limited functionality like Wi-Fi only usage. Key Limitations iPhone 4s FULL iCloud Bypass Tutorial
The DNS bypass was very popular years ago, but it is highly unreliable today as the servers running the exploits are often shut down. The iPhone 4s is particularly bad at this because iOS 9 handles network handshakes differently than iOS 10+.
Why? The baseband chip (which manages cellular radio) is separate from the main OS. Even if you bypass the setup screen, the baseband checks the activation ticket stored in the FairPlay subsystem. Without a valid ticket matching the IMEI to a specific SIM and Apple ID, the baseband will show "No Service" or "Searching."
The iPhone 4s is a legendary device, but getting stuck on the iCloud Activation Lock screen can turn this classic piece of hardware into a paperweight. If you have a 4s running iOS 9.3.6—the final update for this model—you might be looking for a way back in.
