Bypassing an Activation Lock on an iPhone 4s (running iOS 9.3.5) is generally restricted by Apple's security protocols, which link the hardware directly to an Apple ID in their servers. Standard factory resets or iTunes restores will not remove this lock, as the device will still require the original credentials upon setup. Official Removal Methods
The most reliable way to clear the lock is through official Apple channels:
Previous Owner: If you bought the device used, the former owner can remove it remotely. They must sign in to the iCloud Find My page, select the device, and click Remove This Device.
Apple Support: If you have the original proof of purchase, you can submit an Activation Lock support request to Apple for assistance in unlocking it. Third-Party Workarounds
Because the iPhone 4s is an older 32-bit device, some unofficial methods are often discussed in community forums, though they come with significant limitations:
DNS Bypass: This involves changing your Wi-Fi DNS settings to a third-party server (like 104.154.51.7). This does not fully unlock the phone but allows you to access a "captive portal" with basic features like a web browser, maps, and music. It does not provide access to the home screen or cellular functions. iphone 4s activation lock bypass ios 9.3.5
Jailbreak-based Tools: Tools like Sliver or Checkm8-based exploits sometimes target older hardware. However, since the iPhone 4s uses the A5 chip, it is not compatible with the popular checkm8 bootrom exploit found on newer (but still old) models like the iPhone 5s through X.
Paid Software: Be cautious of "unlocking services" or software that claim to bypass the lock for a fee. Many of these are ineffective or only provide a "tethered" bypass that disappears if the device restarts.

If you cannot contact the previous owner, here are the primary community-led methods: 1. iCloud DNS Bypass (The "Soft" Bypass)
This is not a full unlock but a way to use the device's features via a custom server. How it works: You change the DNS settings
in your Wi-Fi configuration to point to a third-party server (e.g., 104.154.51.7 for North America). Easy to do; no computer or cables required.
Very limited access; you can only use specific apps like a web browser, YouTube, or basic games through the server's menu. 2. Hardware Exploits (Checkm8-A5) checkm8 exploit allows for a deeper bypass but requires specific hardware. Requirements: Often requires an Arduino Uno USB Host Shield Raspberry Pi Pico to put the A5 chip into "Pwned DFU" mode. Functionality: This can allow you to delete the file, which skips the activation screen entirely. Limitations:
This often results in a "tethered" bypass (must re-run the exploit if the phone dies) and usually disables SIM card services (no calls or SMS). 3. Software Tools
Several third-party tools claim to automate this process by connecting the device to a PC or Mac.
iPhone 4S Activation Lock Bypass on iOS 9.3.5: Comprehensive Guide
The iPhone 4s remains a classic piece of hardware, but many users find themselves stuck on the Activation Lock screen when trying to revive one running iOS 9.3.5. Whether you’ve inherited an old device or bought one from a thrift store, getting past that "Hello" screen without the original owner's credentials can be challenging. Official Removal Methods
Before attempting third-party workarounds, Apple provides official channels to unlock your device. These are the only methods guaranteed to be permanent and safe.
iCloud.com (Original Owner Only): If you can contact the previous owner, they can remove the device remotely. They simply need to log in to the Apple Find My web portal, select the iPhone 4s, and click Remove from Account.
Apple Support Request: If you have the original proof of purchase documentation, you can start an Activation Lock support request directly through Apple. Hardware-Based Bypass (The "Arduino" Method)
For the iPhone 4s and iPad 2 running iOS 9.3.5, standard software tools often fail. Many experienced users recommend using an Arduino Uno and a USB Host Shield.
How it Works: This hardware setup allows you to put the device into a special "pwned DFU" mode. Report: iPhone 4S Activation Lock Bypass on iOS 9
Legacy iOS Kit: Once in this mode, you can use tools like the Legacy iOS Kit to "hacktivate" the device or even downgrade it to more stable versions like iOS 6.1.3. Software Tools and Glitches
While less reliable, several software-based attempts exist for those without specialized hardware.
DNS Bypass: A popular temporary workaround involves changing your Wi-Fi DNS settings to a bypass server. This doesn't remove the lock but lets you use the iPhone for web browsing, videos, and music.
VoiceOver Glitch: 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.
Third-Party Tools: Software like iRemove Tools or AnyUnlock claim to support iOS 9 activation bypasses. However, these are often "tethered," meaning the lock may return if the device restarts.

How to Bypass Activation Lock on iPhone & iPad (Legal Guide) - Zecurit
Is it legal to bypass Activation Lock? Yes, as long as you own the device or have the original owner's consent.
Bypassing the Activation Lock on an iPhone 4s running iOS 9.3.5 is difficult because modern exploits like checkm8 generally do not support the A5 chip found in this model. While there are legitimate ways to remove the lock, "bypass" methods often result in a device that is tethered or lacks cellular functionality. Legitimate Methods (Recommended)
The only permanent and safe way to remove the lock is through official Apple channels or with the original credentials.
Original Credentials: If you have the Apple ID and password, sign in directly on the device or remove it remotely via iCloud Find My.
Apple Support Request: If you are the original owner but lost access, you can submit an Activation Lock support request if you have the original proof of purchase.
Device Passcode: In some cases, iOS allows you to unlock the device using its previous passcode instead of the Apple ID. Bypass Tools and Workarounds
Third-party tools and "tricks" are often unreliable and may compromise your device's security.
Checkm8-A5 with Arduino: Some advanced users use an Arduino with a USB Host Shield to execute a checkm8-based exploit for A5 devices. However, this is complex, often tethered (requires re-running after every reboot), and typically leaves the phone without cellular signal or iCloud service access.
Third-Party Software: Tools like Dr.Fone or iRemove claim to bypass locks on older iOS versions. Note that these often require a paid license and may not fully support the 4s on 9.3.5.
DNS Bypass: This involves changing Wi-Fi settings to point to a custom DNS server. It does not unlock the phone; it merely provides a captive portal to access some web-based apps and games while keeping the device otherwise locked. Why It's Challenging in 2026
As of March 2026, the iPhone 4s is officially considered obsolete by Apple. Many bypass methods for older devices (like the iPhone 4) do not work on the 4s due to its different hardware architecture. Additionally, many legacy tools no longer function on modern operating systems like Windows 11 or the latest macOS.
Do you have the original sales receipt for the phone, or are you trying to recover a device from a previous owner? How to remove Activation Lock - Apple Support
Bypassing the Activation Lock on an iPhone 4s running iOS 9.3.5 is possible through several official and unofficial methods. While official channels are the safest and most reliable, technical workarounds exist for users who cannot contact the original owner. Official Removal Methods (Recommended)
These methods permanently remove the lock and allow full use of the device, including cellular services and the App Store.
Apple Support Request: If you have proof of purchase, you can submit a support request to Apple. You will need to provide the device's serial number or IMEI. Music and video streaming Social media and online
iCloud.com: If you can contact the previous owner, they can remove the device remotely. They must sign in to iCloud.com/find, select the iPhone 4s, and click Remove from Account.
Device Passcode: In some cases, iOS allows you to unlock the device using its own screen passcode if "Find My" was active but you know the pin that was previously on the device. Technical Bypass Methods
For older devices like the iPhone 4s, certain technical exploits can "skip" the activation screen. Note that these may not restore cellular functionality.
Checkm8 Exploit: The iPhone 4s is vulnerable to the checkm8 bootrom exploit, which is unpatchable by Apple. Tools like CheckM8 use this to skip the activation step.
Note: Using this often requires putting the device into DFU mode by holding the Power and Home buttons in a specific sequence while connected to a computer.
DNS Bypass (Limited Access): This is a temporary "glitch" rather than a full unlock. By changing your Wi-Fi DNS settings to specific third-party servers (e.g., 104.154.51.7), you can access a web-based interface to watch videos or use social media, but you cannot access the actual iOS home screen.
Arduino + USB Host Shield: A more advanced community-driven method involves using an Arduino Uno and a USB Host Shield to put the device into a "pwned DFU" mode, allowing you to delete the Setup.app file that triggers the lock. Summary of Bypass Tools
I notice you're asking about bypassing the Activation Lock on an iPhone 4s running iOS 9.3.5.
Important note: Activation Lock is an anti-theft security feature from Apple. Bypassing it without the original owner's Apple ID and password is not legitimate unless you are the rightful owner and have lost access to your account.
If you own the device and need help recovering access, here are legitimate steps:
What won't work:
Security warning: Avoid articles that encourage bypassing Activation Lock without ownership proof — they may violate laws or Apple's terms of service.
Q: Will a bypassed iPhone 4s work with any SIM card?
Q: Can I update iOS after a bypass?
Q: Is this legal?
Q: Why won’t my computer recognize the iPhone 4s in DFU mode?
Due to the 4s being 32-bit, several exploits work that do not work on newer iPhones.
The iPhone 4s uses a 32-bit A5 chip. iOS 9.3.5 is the last version Apple signed for this architecture. Modern bypass tools (like Checkm8 or Sliver) work differently on 32-bit devices than on 64-bit devices. This creates a unique window of opportunity.
Remember: The iPhone 4s is a 32-bit relic. As of 2025, Apple will likely stop supporting activation servers for this device entirely, meaning future bypasses may become impossible. If you have a locked 4s on iOS 9.3.5, your window to unlock it is right now.
Activation Lock is Apple’s anti-theft feature, part of the “Find My iPhone” suite. When enabled, the Apple ID and password are required to erase, reactivate, or disable the device. On an iPhone 4s running iOS 9.3.5, this lock is particularly stubborn because Apple no longer supports the device with software updates, but the activation servers still check for valid credentials.
For an iPhone 4S on iOS 9.3.5, some users have reported success with DNS bypass methods. Here’s a simplified overview:
78.109.17.60 (note: this can vary, and you might need to search for the most current DNS server addresses used for bypassing).The iPhone 4s running iOS 9.3.5 is slow by modern standards. Most apps require iOS 10 or later. However, as a music player, podcast machine, emergency phone, or classic gaming device, it’s fantastic. Bypassing the Activation Lock gives new life to a device that Apple has essentially abandoned.
