This method is often referred to as the or utilizing the checkm8 hardware exploit .
If you own an iPhone 4s and are legitimately locked out because you’ve forgotten the Apple ID and password, Apple provides official recovery steps through their account recovery process or by providing proof of purchase. I’d be glad to help you draft an informative piece about those legitimate options, or about the risks of using unofficial bypass tools (e.g., data theft, malware, or device bricking). Let me know how you’d like to proceed.
Activation Lock is an anti-theft security feature designed by Apple that links an iOS device to its owner's Apple ID and password. It automatically activates when "Find My iPhone" is enabled and is designed to prevent anyone else from using, selling, or erasing the device, making it a significant barrier for those who have forgotten their credentials or purchased a second-hand phone that hasn't been properly cleared. For the iPhone 4S, which runs iOS 9.3.5 as its last supported version, the lock is enforced by a system process called Setup.app . Removing or bypassing this lock is the primary goal of all the methods discussed below.
For a complete, untethered bypass where you can access the actual iOS 9.3.5 user interface, you must exploit a hardware vulnerability. The iPhone 4s contains an A5 processor vulnerable to the checkm8 and alloc8 bootrom exploits. Because the device is locked, you must force it into a Special DFU (pwnedDFU) mode using external hardware. Hardware Required A computer (Mac or Linux preferred) An board
: Tap Back , select your Wi-Fi network, and enter your password.
If already connected, tap the 'i' icon next to your Wi-Fi name and select "Forget this Network." iphone 4s activation lock bypass ios 935 extra quality
The Complete Guide to iPhone 4S Activation Lock Bypass on iOS 9.3.5
Utilizing an Arduino Uno hardware board with a USB Host Shield allows developers to exploit the A5 chip's bootrom via a checkm8-A5 port.
: Turn on your iPhone 4s and navigate to the Wi-Fi selection screen.
Because the iPhone 4S features a 32-bit A5 processor, it lacks the hardware-level vulnerabilities found in later devices (like the Checkm8 exploit on the iPhone 5S through iPhone X). However, because it runs legacy software, there are a few authentic ways to address the lock. 1. The Official Route (Free)
The Reality of iPhone 4S Activation Lock Bypass on iOS 9.3.5 This method is often referred to as the
Activation Lock on the iPhone 4s running iOS 9.3.5 can turn an iconic piece of hardware into an unusable paperweight. This security feature links the device directly to the original owner's Apple ID. If you bought the phone secondhand or forgot your old credentials, getting past this screen requires specific methods.
Sliver, developed by security researcher AppleTech752, is a free macOS utility that supports older A5/A6 devices including the iPhone 4S. Version 6.2 supports macOS 10.14 through 12.3, including M1 Macs.
Here are the most practical and tested methods to bypass the activation lock on your iPhone 4S.
: The LED on the Arduino will blink rapidly. Once the LED turns solid, the iPhone 4s is successfully placed into a "Pwnd DFU" (exploited) state.
Several software tools exist that promise a more comprehensive bypass. Because the iPhone 4S uses an older A5 chip, it is susceptible to exploits. Let me know how you’d like to proceed
For advanced technical users, older software tools like Sliver (developed by Apple Tech 752) can bypass the setup app on iOS 9.3.5.
For iPhone 4S (A5 chip), the tool supports iOS versions up to 9.3.5/9.3.6, though performance may vary.
Before you attempt any bypass methods, you must ensure your device and workstation are ready. Because the iPhone 4S runs an older 32-bit architecture, modern tools designed for newer iPhones will not work. You will need the following tools and materials:
Keep the device steadily connected until the progress bar reaches 100% and the phone automatically reboots to the home screen. Limitations of a Bypassed iPhone 4s
