Target Device: iPhone 4s (GSM & Global)
Target Firmware: iOS 9.3.5 (build 13G36)
For users without receipts, the following workflow provides the best user experience on iOS 9.3.5.
The most famous tool for this is Sliver (part of the legacy suite from the same developers as Checkra1n). Here is the technical flow of the "extra quality" bypass (the version that survives reboots for a limited time):
com.apple.springboard.plist that stores the lock state.albert.apple.com) to a local server running on your Mac. This local server sends back a “Activation Complete” packet that is valid for the 4s’s legacy protocol but would be rejected by any newer iPhone.activation_records plist on the raw NAND. Because the 4s doesn’t have the Secure Enclave (introduced with the iPhone 5s), this record isn’t cryptographically signed to the device’s GID key in the same way. It’s just… data.Result: The iPhone 4s wakes up. The Apple ID prompt is gone. You can use the camera, notes, music, and even make emergency calls.
Once jailbroken, the Setup.app (the lock screen) is still running. We need to manually disable it.
/System/Library/CoreServices/Result: The iPhone will boot directly to the Springboard (home screen). You have achieved an extra quality bypass – the lock screen is gone permanently. However, iCloud services will fail because the activation ticket is missing.

Difficulty: Intermediate
Devices Covered: Apple iPhone 4s (GSM & CDMA)
Firmware Required: iOS 9.3.5 (Build 13G36)
For users seeking a genuine solution in 2024, the software Sliver (developed by Apple Tech 752) is widely regarded as the "extra quality" standard for older devices.
Steps to use Sliver for iPhone 4s:
Note: With iOS 9.3.5, you may face issues with "Push Notifications" or "Battery Drain" post-bypass. These are common side effects of altering the system partition.
Downside: Requires soldering-level patience. Not for absolute beginners.
If your error is "SIM Not Supported," software bypasses will fail. You need an IMEI Factory Unlock. This is the only "Extra Quality" solution for a carrier lock.
IMEI.info to check which carrier the phone is locked to (this usually costs a few dollars).Technical Analysis of iPhone 4S Activation Lock Bypass on iOS 9.3.5
The iPhone 4S running iOS 9.3.5 represents a unique intersection of legacy hardware and firmware security. While modern iOS versions feature hardened, chip-level hardware encryption, the 32-bit architecture of the iPhone 4S allows for several documented—though often limited—bypass techniques. Summary of Known Methods DNS Bypass
: A widely documented method involving manual modification of DNS settings (e.g., to 104.154.51.7
) during the initial Wi-Fi setup. This does not remove the lock but redirects the device to a third-party server, allowing limited access to games, web browsing, and social media through a browser-based interface. Software-Based Exploits : Tools like attempt to delete or modify the
file within the iOS file system. Success typically results in a "hactivated" state where the device is usable as a media player, but cellular services (SIM signal), iMessage, and FaceTime often remain disabled. Official Removal : Apple provides the only permanent solution through an Activation Lock support request iphone 4s activation lock bypass ios 935 extra quality
, provided the user can supply proof of purchase such as a store receipt or invoice. Technical Challenges & Vulnerabilities About the security content of iOS 9.3.5 - Apple Support
Bypassing the Activation Lock on an iPhone 4s running iOS 9.3.5 is technically challenging because Apple's security link is tied to the device's hardware serial number. While several unofficial methods exist, they often come with significant limitations, such as losing cellular signal or having the lock return after a restart. Official Methods (Recommended)
The most reliable and permanent way to remove the lock is through official channels:
iCloud.com: If you have the Apple ID credentials, or can contact the previous owner, they can remotely remove the device by signing into the Find My iPhone tool on iCloud and selecting Remove from Account.
Apple Support: If you have the original proof of purchase (invoice), you can start an official Activation Lock support request to have Apple unlock the device for you. Unofficial Bypass Options
If official routes are unavailable, these community-identified methods may provide limited access:
DNS Bypass (Limited Access):This method allows you to use a "pseudo-interface" with apps like YouTube and maps without actually bypassing the lock for the whole phone. Go to Wi-Fi Settings on the activation screen.
Tap the 'i' icon next to your network and select Configure DNS.
Enter one of the following IP addresses based on your region: USA: 104.154.51.7 Europe: 104.155.28.90 Asia: 104.155.220.58 Tap Back and then Activation Help.
Arduino with Checkm8-A5 (Hardware Required):For a more "complete" bypass, some users utilize an Arduino board and a USB Host Shield to execute the checkm8-a5 exploit.
Pros: Can lead to a "tethered" bypass where you can see the home screen.
Cons: Requires hardware, will likely result in no cellular signal, and may require re-running the process if the phone restarts.
Software Tools:Tools like iRemove Tools claim to offer a free "tethered" bypass for iPhone 4s on Windows, though this typically leaves the device in a state where it cannot make calls.
Warning: Be cautious of "extra quality" paid tools found in YouTube descriptions or forums. Many are unreliable or contain malware. Official Apple support is the only way to permanently and fully restore the device's functionality.

Bypassing the Activation Lock on an iPhone 4S running iOS 9.3.5 is technically challenging because Apple has patched most simple software glitches. While some tools claim "extra quality" results, many are unreliable or potential scams.
The following sections outline legitimate methods and known technical workarounds. Official Removal Methods
The most reliable way to remove Activation Lock is through official Apple channels.
Original Credentials: Sign in with the Apple ID and password originally used to set up the device.
Previous Owner: If you bought the phone secondhand, ask the previous owner to remove the device from their account via iCloud Find My.
Apple Support: If you have the original proof of purchase, you can submit an Activation Lock support request to Apple. Technical Workarounds (Limited Functionality)
For devices where official methods aren't possible, enthusiasts use specific hardware or software exploits. Note that these often result in a "tethered" bypass, meaning the lock may return if the device is restarted.
Bypassing the iCloud Activation Lock on an iPhone 4s running iOS 9.3.5 is a technical challenge because the device uses the A5 chip, which requires a hardware-based exploit. Unlike newer devices that can be bypassed using software alone, the iPhone 4s generally requires an Arduino Uno and a USB Host Shield to run the "checkm8-A5" exploit. Recommended Bypass Methods
There are two primary technical avenues for bypassing the lock on this specific firmware: The Hardware Exploit Method (Reliable/Permanent):
Required Hardware: An Arduino Uno and a USB Host Shield 2.0. Software: Use tools like Sliver or Legacy iOS Kit.
Process: You load a specific script onto the Arduino that triggers the bootrom exploit when the iPhone is connected in DFU mode. Once "pawned," the software can delete the Setup.app file, allowing you to reach the home screen. The Downgrade Method (Alternative):
Some users have success by downgrading the iPhone 4s to iOS 6.1.3 using Legacy iOS Kit.
On iOS 6.1.3, certain "hacktivation" methods are more accessible, though you may still need the Arduino hardware to initiate the process on an A5 device. Common Limitations
While these methods can get you past the "Activation Lock" screen, they often come with significant trade-offs: Enter DFU Mode: You put the 4s into
No Cellular Service: Most free bypasses are "tethered" or "no signal," meaning you cannot make calls, use SMS, or use cellular data.
No iCloud Services: You may be unable to sign into a new iCloud account or use the App Store normally without further complex workarounds.
Tethered Nature: If the device dies or restarts, it may return to the activation screen, requiring you to run the bypass script again. Legitimate Alternatives
If you are the original owner or have proof of purchase, the following official routes are always better than a technical bypass:
Bypassing the Activation Lock on an iPhone 4s running iOS 9.3.5 is possible, but reviewers and community experts emphasize that it is a complex process often requiring additional hardware or specific software environments. Most "one-click" online tools are scams Proven Bypass Methods Arduino + USB Host Shield (Recommended)
: This is considered the most reliable "hard" method for A5 devices like the iPhone 4s . It involves using an Arduino Uno USB Host Shield
to put the device into a "pwned DFU" mode, allowing for a permanent or "untethered" activation bypass Silver (Mac Only)
: Sliver is a well-known community tool that can bypass A5 devices on iOS 9.3.x, but it often requires the aforementioned Arduino setup to function correctly Legacy iOS Kit
: This tool can be used on Linux or Mac to downgrade the iPhone 4s to iOS 6.1.3 or 8.4.1, which sometimes resolves activation issues or allows for easier "hacktivation" DNS Bypass (Limited)
: A quick, software-only method involves changing Wi-Fi DNS settings (e.g., using 104.154.51.7 for North America) . This does
fully unlock the phone but provides a portal to use the web, YouTube, and some basic apps through a dedicated server Critical Considerations

Which of these would you prefer?
Bypassing the Activation Lock can be attempted through official Apple methods, DNS server redirects, or specialized software tools. However, many unofficial methods only provide limited access and do not fully unlock the device for normal use. Official Methods (Recommended)
The most reliable and permanent way to remove the lock is through official channels: Previous Owner Removal
: If you purchased the phone second-hand, the original owner can remotely remove the lock by signing into iCloud Find Devices , selecting the iPhone 4s, and clicking "Remove from Account" Apple Support Request
: If you are the original owner and have valid proof of purchase (original receipt), you can submit an Activation Lock Support Request directly to Apple to have the lock cleared. Apple Support Alternative Bypass Methods
