The home screen materialized. The vintage, comforting blue gradient of iOS 9 wallpaper greeted him. The icons for Calendar, Photos, and the old Maps app were arranged in their perfect grid.
Before attempting high-risk hardware or software modifications, always pursue the official methods. These are the only ways to guarantee a fully functional device with working cellular signals and iCloud services. 1. The iCloud Web Removal
Before gathering tools, understand what happens after a successful hardware hacktivation:
This method tricks the iPhone into believing it has connected to Apple’s activation servers, allowing it to proceed to the home screen. Prerequisites iPhone 4S (iOS 9.3.5) A stable WiFi network Step-by-Step Instructions

The good news is that legitimate, open‑source tools do exist and have been proven to work. The checkm8 exploit has opened doors for the security research community, resulting in tools like HFZ Universal Activator, A5_Bypass_OSS, and various A5 bypass utilities that can restore locked devices to functional status. However, each comes with trade‑offs in terms of features retained, persistence across reboots, and technical difficulty.
You need the original receipt showing the device’s serial number or IMEI.
The process may fail many times before it works. Persistence is required, as the exploit can be temperamental, especially on certain device revisions.
The iPhone 4S remains a landmark device in Apple's history. It was the first to introduce Siri and the final device overseen by Steve Jobs. Many of these legacy devices still exist today. However, a significant number of them are trapped behind an Activation Lock screen on iOS 9.3.5, which was the final software update released for this model.
He connected the phone to his battered MacBook. He didn't use official software. Instead, he opened a terminal window, his fingers flying over the keys to launch a custom script he’d archived years ago. It wasn’t a hack that removed the lock from Apple’s servers; it was a "bypass." A trick of the light. It fooled the Setup Assistant into thinking it had verified with Apple when it actually hadn't.
It's worth noting that newer iOS versions and devices have additional security measures in place, making bypassing the activation lock much more challenging.
The is a permanent, unpatchable bootrom vulnerability affecting all Apple devices with A5 through A11 chips – which includes the iPhone 4S through iPhone X. Because it lives in the bootrom (read‑only memory), Apple cannot fix it with software updates, making it the most reliable foundation for bypassing Activation Lock on older devices.
A less hardware-intensive but more fragile method involves redirecting the device's activation request to a custom server. Mechanism: Users host a specific PHP script (like the sliver.php file) on a private web server. Execution: By modifying DNS settings or using tools like ideviceactivation
: Connects the iPhone 4s to the USB Host Shield.
If you use Method 2 or Method 3 to bypass the Activation Lock, you are altering the local file system rather than clearing the status on Apple's servers. This results in several permanent limitations:
: The original Apple syncing cable.
While there is no magical "one-click" software that will permanently turn an iPhone 4S into a brand-new device without the original credentials, there are a few legitimate pathways to explore. Method 1: The Official Apple Route (Free)
