Most bypass methods render the device unable to connect to cellular networks, meaning you cannot make phone calls or use mobile data.
Because the iPhone 4s relies on the , it does not support standard bootrom-based exploits like Checkm8. Bypassing it completely requires a mix of hardware exploitation tools (like an Arduino setup) or soft DNS workarounds. This comprehensive guide details every actionable option to address the "iPhone 4s activation lock bypass ios 9.3.5" dilemma. Comprehensive Comparison of Bypass Methods Access Level Difficulty Success Rate Requirements DNS Bypass Limited App Portal Wi-Fi Connection only Sliver / RAMdisk Untethered Home Screen Mac, Arduino Board, USB Host Shield Official Apple Request Factory Reset / Full Access Medium-High Proof of Purchase Method 1: The Wi-Fi DNS Bypass (Easiest & Fastest)
: If purchased second-hand, ask the previous owner to remotely unbind the device from their iCloud account using the method above. Apple Support Request
: Connect the iPhone 4s directly into the USB Host Shield mounted onto the pulsing Arduino. The Arduino’s LED indicator will blink rapidly and then stay solid, signaling the device is successfully exploited. iphone 4s activation lock bypass ios 9.3.5
In the annals of mobile computing, few devices have aged as gracefully yet tragically as the iPhone 4S. Released in 2011, it was the swan song of the Steve Jobs era, a device that defined the modern smartphone blueprint. However, for a specific subset of users and technologists, the iPhone 4S represents something else entirely: the final battlefield of the "Right to Repair" and the cat-and-mouse game of security exploitation. The quest to bypass the Activation Lock on an iPhone 4S running iOS 9.3.5 is not merely a technical procedure; it is a philosophical inquiry into digital ownership, the planned obsolescence of secure hardware, and the resilience of legacy code.
Advanced users sometimes use an Arduino Uno with a USB Host Shield to put the A5 chip into "pwned DFU" mode. This allows for a more "untethered" bypass, though it requires external hardware and technical knowledge of Arduino IDE. If your Apple Account is locked, not active, or disabled
For the iPhone 4s, which is an older device, these methods are often more feasible because its security architecture is less complex than modern iPhones. Most bypass methods render the device unable to
: Some users exploit a temporary glitch on iOS 9 by enabling VoiceOver (triple-click Home button), changing languages, and repeatedly resetting until the home screen briefly appears. Note that this is usually temporary and does not fully unlock the phone.
: A widely cited toolkit for bypassing older A5 devices like the iPhone 4s using an Arduino. Legacy iOS Kit
: If the previous owner is willing, they can sign in to the iCloud Find My page , select the iPhone 4s, and choose "Remove from Account" . This is the most reliable way to clear the lock instantly. This comprehensive guide details every actionable option to
A computer running macOS or Linux (Windows compatibility is highly limited for these scripts).
The only permanent and safe way to remove the lock is through official channels:
If you successfully bypass the activation screen using a software crack or ramdisk modification, the device will still suffer from severe restrictions: ❌ Broken
: Flash your Arduino Uno using a Mac running the Arduino IDE software to load the checkm8-A5 sketch.
The absolute safest and most official route to solve a blocked old phone is directly asking Apple to erase the iCloud identity mapping from their server registry. Step-by-Step Instructions:
