This is the most archaic but surprisingly effective method for iOS 9.3.5.
Using a Mac, you run:
ipwnder -p
./checkm8 -p
./iphonerecovery -p
./idevicererestore -l bypass_935.ipsw
This injects a custom ramdisk that deletes the Setup.app globally.
Warning: This method often breaks the Notification Center and Control Center. It is not "best" for daily driving, but it is the fastest for file recovery (extracting photos off a locked phone).
For those looking to breathe life back into an old iPhone 4s running iOS 9.3.5, the "best" path depends on whether you want a software-only fix or are willing to tinker with hardware for a more stable result. The Most Reliable Method: Arduino & Sliver
Experts and hobbyists generally consider the Arduino method to be the most effective for the iPhone 4s (an A5 device) on iOS 9.3.5. This hardware-based approach utilizes the checkm8-a5 exploit to "hacktivate" the device.
Requirements: You will need an Arduino Uno board and a USB Host Shield.
The Tool: Use Sliver on a Mac. It includes dedicated modules for A5 devices like the iPhone 4s.
The Result: This effectively removes the Setup.app. While it provides access to the home screen, note that you typically will not have cellular signal or the ability to sign into iCloud for iMessage/FaceTime. The Software Alternative: Ramdisk Bypass
If you don't have an Arduino, you can use specialized software tools that create a "Ramdisk" to bypass the activation screen.
iRemove Tools: Offers a free iCloud Bypass for older devices like the 4s. It is a "tethered" bypass, meaning if the phone dies or restarts, you may need to run the tool again to unlock it.
Legacy iOS Kit: A popular community tool that can be used on Linux or Mac to restore the device or perform various "hacktivation" tasks.
Dr.Fone: This toolkit provides a more user-friendly interface for those less comfortable with terminal commands, though it often involves a paid license for full functionality. The Community "Glitch" Method
For a quick, non-permanent look at the home screen without a computer, some users exploit system glitches: Enable VoiceOver by triple-clicking the Home button. Select a different language and double-tap.
Simultaneously hold the Power and Home buttons until the device resets.
As it reboots, releasing the Home button while holding Power can sometimes trigger a fleeting view of the home screen. Official Solutions If you are the original owner or can contact them: iCloud Bypass (Unlock) - iRemove Software
Bypassing the iCloud Activation Lock on an iPhone 4S running iOS 9.3.5 is technically possible, but it is no longer a simple software "click." Because the iPhone 4S uses the A5 chip, it requires a specific hardware-based exploit (checkm8-a5) and an Arduino board to put the device into a state where the lock can be bypassed. The Best Current Method: Arduino + Sliver
As of 2026, the most reliable and "untethered" (permanent after reboot) method for the iPhone 4S on iOS 9.3.5/9.3.6 involves using an Arduino Uno with a USB Host Shield. Required Equipment
Hardware: Arduino Uno R3 and a USB Host Shield (must be "bridged" with solder).
Software: Sliver (by AppleTech752) or similar tools like checkm8-a5.
Computer: A Mac is generally required for the Sliver toolset. High-Level Process
Preparation: Load the checkm8-a5 exploit code onto your Arduino using the Arduino IDE.
DFU Mode: Put your iPhone 4S into DFU mode and connect it to the Arduino's USB Host Shield.
Exploit: The Arduino will pulse its LED once the exploit is successfully injected into the device's bootrom.
Bypass: Connect the iPhone back to your Mac and use Sliver to delete the Setup.app or perform a "Ramdisk" bypass. Alternative: DNS Bypass (Temporary) iphone 4s ios 935 icloud bypass best
If you do not have hardware tools, you can use a DNS Bypass. This does not unlock the phone, but it lets you use specific web-based apps, watch videos, and browse the web. Pros: Free, no computer needed, instant.
Cons: Very limited; you cannot use the phone's native apps or cellular features. How-to: Go to Wi-Fi Settings on the "Hello" screen. Tap the 'i' next to your network.
Change DNS to: 104.154.51.7 (USA) or 104.155.220.58 (Europe). Tap Back and select Activation Help. ⚠️ Critical Warnings
Scam Software: Avoid websites asking for money to "remotely" unlock your device via IMEI. These are almost universally scams.
Functionality: Most bypasses (except high-end paid services or hardware-based Ramdisk methods) will not support SIM card signal or iMessage/FaceTime.
Legality: Only perform these steps on a device you legally own. Bypassing locks on stolen devices is illegal. Official Recommendation
The only "official" way to remove the lock is to submit an Activation Lock support request to Apple. You must provide the original proof of purchase (receipt).
Sliver 6.2 introduced a "Signal" bypass using an Arduino and a USB Host Shield. This method actually restores Cellular Data (3G) and allows Call History.
| Method | Permanence | iCloud/App Store | Cellular | Difficulty | Cost | |--------|------------|------------------|----------|------------|------| | Legacy-iOS-Kit (untethered) | Permanent | No | No | Medium | Free | | DNS Bypass | Temporary (per boot) | No | No | Very Easy | Free | | Serial Number Change | Permanent | Yes | Yes | Very Hard | ~$20 (programmer) | | Paid Software (e.g., iRemoval) | Permanent | No | No | Easy | $10-20 |
On an iPhone 12 or newer, iCloud bypass is either impossible or requires expensive, unreliable server-side tricks. On the iPhone 4s (iOS 9.3.5), you have three main advantages:
The best method today (2026) is a full, untethered bypass using a modified IPSW and a tool like Sliver or Legacy-iOS-Kit.
| Pros | Cons | |------|------| | Perfect dedicated MP3 player | Bypass is temporary and buggy | | Runs exclusive 32-bit games | Most modern streaming apps fail | | Free from distracting notifications | Battery life is poor (often needs replacement) | | Headphone jack & compact size | No security updates since 2016 |
The Bottom Line:
If you’re looking for a lifestyle device to detox from social media and a dedicated entertainment machine for retro gaming and music, the iPhone 4s on iOS 9.3.5 is a charming, cheap solution. However, pursuing an iCloud bypass is only for tech enthusiasts willing to tinker. For most, buying a clean, unlocked unit for $20–30 is the smarter, safer path to vintage iOS bliss.
Whether you bypass it or unlock it legitimately, the iPhone 4s proves that old tech, when repurposed creatively, still has a vibrant second life.

Bypassing the iCloud Activation Lock on an iPhone 4s running iOS 9.3.5 is a complex process because modern software tools often focus on newer exploits. However, for those with a bit of technical patience, it remains one of the more "hackable" legacy devices due to its older architecture.
Below is a detailed review of the best current methods as of early 2026, ranging from simple DNS bypasses to more permanent hardware-assisted solutions.
1. The Hardware King: Arduino + USB Host Shield (Recommended)
For a permanent "hacktivation," the community consensus is that hardware is the most reliable path.
How it works: You use an Arduino Uno combined with a USB Host Shield to send specific commands to the iPhone 4s while it is in DFU (Device Firmware Update) mode.
Pros: This is a permanent solution that bypasses the "Setup.app" entirely, allowing you to use the phone locally without it re-locking every time you reboot.
Cons: Requires purchasing physical hardware (though an Arduino can often be found cheap second-hand) and some basic coding/terminal knowledge. 2. The Software Easy Route: iRemove Tools & MagFone
If you prefer a one-click software experience and are willing to pay for a license, specialized tools like iRemove Software or MagFone iPhone Unlocker are popular choices.
Performance: These tools automate the exploit process. Reviews on Trustpilot generally praise their simplicity, particularly for users on macOS or Linux. This is the most archaic but surprisingly effective
Limitations: Most of these software-only bypasses on the iPhone 4s are tethered, meaning you cannot make calls or use cellular data after the bypass. They are best for turning an old brick into a dedicated music player or Wi-Fi device. 3. The Free "No-Install" Method: DNS Bypass
This is the fastest method to "peek" inside the device without any downloads or hardware. The Process: Go to Wi-Fi settings on the Activation Screen.
Tap the "i" next to your network and change the DNS settings.
Use a server like 104.154.51.7 (North America) or 104.155.28.90 (Europe).
Verdict: This isn't a true bypass; it’s a portal. You get a custom menu to use the browser, watch YouTube, or play games, but you never actually reach the iOS home screen. It's a great "Plan B" but not a permanent fix. 4. The Legacy Downgrade: iOS 6.1.3 Restore
Because iOS 9.3.5 is quite heavy for the 4s, many users choose to bypass and then immediately downgrade to iOS 6.1.3 using tools like Legacy iOS Kit.
Why do this? iOS 6 is significantly faster on this hardware. Some bypass methods work more effectively on older versions where the security protocols were less rigorous. Final Verdict: Is it worth it?
Best Overall: Arduino + USB Host Shield. It's the only way to get a "clean" feel on the device.
Best for Beginners: iRemove Tools. Highly rated for its "one-click" nature, though limited in functionality.
Best Free Alternative: Raspberry Pi Pico. Emerging as a cheaper and more stable alternative to the Arduino for technical users.
A Note on Ethics & Security: Always ensure you have legal right to the device. Bypassing iCloud can leave the device vulnerable to future locks if you perform a factory reset, as the underlying activation lock remains on Apple's servers.

Bypassing the iCloud Activation Lock on an iPhone 4s running iOS 9.3.5 is technically possible, but it is a complex process compared to newer devices because the iPhone 4s uses the A5 chip. 1. The Hardware Method (Most Reliable)
Unlike the iPhone 4, the iPhone 4s requires external hardware to trigger the necessary exploit (Checkm8-A5).
Hardware Required: You will need an Arduino Uno and a USB Host Shield.
Tools: The most widely recognized software for this is Sliver (from AppleTech752). It allows you to enter "pwned DFU" mode using the Arduino and then "Delete Setup.app" to bypass the activation screen.
Limitations: This method usually results in a "tethered" or semi-functional bypass where cellular services (SIM signal) and iCloud signing-in may not work. 2. DNS Bypass (Easiest, Limited Access)
This is not a full bypass of the system but a way to use the device as a media player/web browser without getting past the activation screen.
How-to: Go to Wi-Fi settings on the "Activate iPhone" screen, tap the 'i' next to your network, and change the DNS settings. DNS Servers: USA: 104.154.51.7 Europe: 104.155.28.90 Asia: 104.155.220.58.
Limitation: You cannot use the actual iPhone interface or apps; you only gain access to a web-based portal with limited features. 3. Third-Party Software Tools
Various paid and free software tools claim to bypass activation, though their success on an A5 device like the 4s is lower than on A7+ devices.
The best methods for bypassing the iCloud Activation Lock on an iPhone 4S running iOS 9.3.5 depend on whether you want a permanent hardware fix or a quick temporary workaround. Because the iPhone 4S uses an A5 chip, it is not compatible with the famous
exploit used for newer devices, meaning software-only permanent bypasses are rare and often unreliable. 1. Best Permanent Method: Arduino + USB Host Shield
This is widely considered the "gold standard" for a permanent bypass on the iPhone 4S. It involves using an Arduino Uno USB Host Shield Using a Mac, you run: ipwnder -p
to send specific commands that exploit the device's bootrom. Why it's best : It allows you to delete the
file permanently, letting you use the phone normally (though often without cellular or iCloud services). Complexity : High. Requires hardware and technical setup. 2. Best Software-Based Method: Sliver (by AppleTech752)
While many of the developer's original tutorials were removed from YouTube,
remains a popular community tool for legacy devices like the iPhone 4S.
: It uses a "private server" method to trick the device into thinking it has been activated by Apple. Limitation
: Often requires a Mac and can be "tethered," meaning the device might relock if it's restarted or restored. 3. Best Instant (Temporary) Method: DNS Bypass
If you just need to access the web, watch videos, or use basic apps without "unlocking" the full system, a DNS bypass is the fastest way. On the "Activate iPhone" screen, press the button and select Wi-Fi Settings next to your Wi-Fi network. Change the DNS settings to one of these regional servers: USA/North America 104.154.51.7 104.154.51.7 104.155.220.58 , and select Activation Help : No computer or special hardware required.
: It only provides a limited web-based interface; you cannot access the actual iOS home screen or local apps. 4. Official Apple Removal
If you have proof of purchase (even for an older device), Apple can remove the lock for you. Apple Support or visit an Apple Store with the original receipt. Alternative
: If you can contact the original owner, they can remotely remove it via iCloud.com by selecting the device and clicking Remove from Account Comparison of Bypass Methods Permanence Difficulty Arduino Hardware Power users wanting full OS access Sliver / Software Semi-Permanent Users with a Mac and technical patience DNS Bypass Quick access to browser/media only Apple Official Low (if eligible) Most reliable and legal solution
Be wary of online "unlocking" services that ask for payment upfront. Many are scams or simply sell "IMEI checks" rather than actual unlocks. How to Bypass iCloud Activation Lock on iPhone/iPad
Finding a reliable method for an iPhone 4s iOS 9.3.5 iCloud bypass is a common challenge for those who have inherited or purchased older Apple devices. While the iPhone 4s is a legacy device, the Activation Lock remains a formidable security feature designed to prevent unauthorized access.
The following guide explores the best current methods for bypassing or removing this lock, ranging from official Apple procedures to technical third-party workarounds. 1. Official Apple Method (Most Recommended)
The most secure and permanent way to remove an iCloud lock is through official channels. This ensures your device remains fully functional without risking security vulnerabilities or software instability.
With Original Credentials: If you have the Apple ID and password, simply enter them on the device during setup. Alternatively, you can remove the device from your account by signing into iCloud.com/find from another computer.
Without Credentials: If you are the legal owner but have forgotten your login details, you can start an Activation Lock support request with Apple. You will typically need to provide proof of purchase (such as the original sales receipt) to verify ownership. 2. DNS Bypass Method (Temporary & Free)
For those looking for a quick, non-permanent solution that doesn't require a computer, the DNS bypass is a popular option. This method doesn't fully unlock the phone but allows you to access a custom server for browsing, games, and basic apps.
How it works: By changing your Wi-Fi DNS settings, you redirect the activation request to a third-party server rather than Apple's official activation servers.
Limitations: This does not remove the lock. You cannot use standard iOS features like making phone calls, sending iMessages, or using the App Store. 3. Technical Hardware & Software Bypasses
For advanced users, there are more technical "hacktivation" methods. These often require a Mac or PC and sometimes specialized hardware.
Arduino + USB Host Shield: A well-known method in the community involves using an Arduino Uno and a USB Host Shield. This hardware setup can exploit the device's bootrom to bypass the activation screen on legacy devices like the iPhone 4s.
Legacy iOS Kit: Some users recommend using the Legacy iOS Kit on a Mac to downgrade the device to iOS 6.1.3, where it may be easier to perform a "hacktivation" than on iOS 9.3.5.
Tethered Bypass Tools: Tools such as iRemove or CheckM8 offer "tethered" solutions for legacy devices. A tethered bypass means the device will remain unlocked as long as it isn't restarted; if it reboots, you will need to re-run the tool on your computer. 4. Third-Party Software Tools
Several third-party developers offer software that claims to "one-click" bypass the activation lock.
