There are third-party tools and software claiming to offer activation lock bypass services. However, many of these tools are scams or may install malware on your device. Some tools might require you to pay a fee. Be cautious and do thorough research before using such services.
For years, the most popular method for the iPhone 4s was the DNS (Domain Name System) trick. This does not require a computer, but it has a low success rate on iOS 9.3.5 in 2023 because Apple has blacklisted most of the DNS servers.
How it works: You trick the phone into connecting to a fake Apple activation server that says "Access Granted."
Steps:
Verdict: Unreliable. Most DNS services are dead. However, if you find a community-updated server, it gives you a semi-functional iPod touch.
Bypassing Activation Lock on an iPhone 4s running iOS 9.3.5 is technically challenging and often yields only limited device functionality. While official methods through Apple are the only way to fully restore the phone, several community-driven workarounds exist for those without the original account credentials. Official Removal Methods
These are the only supported ways to permanently and safely remove the lock with full device functionality.
Original Owner Login: The simplest method is signing in with the original Apple ID and password.
Remote Removal: The previous owner can remove the device by logging into iCloud Find My, selecting the device, and clicking Remove from Account.
Apple Support Request: If you have the original proof of purchase (invoice), you can start a support request with Apple to have the lock removed. Unofficial Community Methods
These methods are for educational purposes and often result in a "hacktivated" device that may lack cellular services or become unstable.
Arduino + USB Host Shield: A popular hardware-based method for A5 devices like the iPhone 4s involves using an Arduino and a USB Host Shield to exploit the device's bootrom. Software Bypass Tools:
Sliver: Often cited in community forums as a tool for A5 device "hacktivation".
3uTools: Can sometimes be used in conjunction with jailbreaking to bypass the setup screen, though this typically leaves the phone as a Wi-Fi-only device.
Temporary Glitches: Some users report glitches involving VoiceOver or language selection that provide a fleeting glimpse of the home screen, though these are typically patched and do not offer permanent access. Important Considerations
Functionality Loss: Most unofficial bypasses will disable iCloud services, iMessage, FaceTime, and cellular connectivity.
Security Risks: Third-party tools can be unreliable, may contain malware, or could permanently brick your device.
iOS 9.3.5 Limits: As the final version for the 4s, many modern exploits do not apply to this specific firmware without hardware assistance. Do you have the original purchase receipt, or
Title: The Ethics and Engineering of the Impenetrable: Analyzing the iPhone 4s Activation Lock on iOS 9.3.5
In the landscape of consumer electronics, few features have been as impactful in the fight against theft as Apple’s Activation Lock. Introduced as part of the "Find My iPhone" service, this security measure effectively bricks a device if it is wiped without the owner's authorization. For a time, the iPhone 4s—running its final supported operating system, iOS 9.3.5—became a focal point for a niche community of hobbyists and security researchers attempting to bypass this digital barrier. The phenomenon of the "iOS 9.3.5 Activation Lock bypass" serves as a compelling case study in the eternal conflict between corporate security measures and the ingenuity of the modding community, raising significant questions about ownership, security, and the right to repair.
To understand the significance of the bypass, one must first understand the architecture of the lock itself. The Activation Lock is not merely a software glitch; it is a handshake between the device and Apple’s servers. When an iPhone is linked to an iCloud account, a record of that linkage is stored on Apple’s backend. Upon restoration or reset, the device demands the credentials associated with that unique identifier. If the server confirms a lock, the device remains unusable. For the iPhone 4s, which was discontinued in 2014 but remains a capable device for basic tasks, being stuck on this screen rendered perfectly functional hardware into electronic waste.
For years, the iPhone 4s represented the "low-hanging fruit" for bypass methods due to the age of its hardware and software. iOS 9.3.5 is the final iteration of iOS 9, an operating system that predates the more rigorous security enclaves found in modern 64-bit devices like the iPhone 5s and later. Because of this older architecture, security researchers discovered various vulnerabilities that allowed for the bypassing of the Activation Lock. These methods often exploited flaws in the setup assistant, cellular activation protocols, or the date and time verification processes. Tools emerged that could trick the phone into thinking it had successfully communicated with Apple’s servers or could skip the verification step entirely.
However, the technical possibility of a bypass does not equate to a restoration of full functionality. Most bypass methods for the iPhone 4s on iOS 9.3.5 were "tethered" or partial solutions. A tethered bypass means that if the phone’s battery dies or the device is rebooted, the user must connect it to a computer and run a specialized tool again to make it usable. Furthermore, critical functions such as cellular service, iMessage, and FaceTime often remained broken. In many cases, the device could only access the home screen and use Wi-Fi, transforming a phone into an oversized iPod Touch. This distinction highlights the robustness of Apple’s baseband security, which operates independently of the application processor that runs the iOS interface.
The ethics surrounding these bypass tools are complex and polarized. On one hand, the bypass community argues for the "Right to Repair" and electronic sustainability. Thousands of iPhone 4s units end up in landfills
Bypassing the Activation Lock on an iPhone 4s running iOS 9.3.5 (the final software version for this model) is a common challenge for those who have purchased a second-hand device or forgotten their legacy Apple account details.
