If you are reading this, you likely have an old iPhone 4s sitting in a drawer, stuck on the "Activate iPhone" screen. Since Apple officially discontinued support for the iPhone 4s, many users find themselves locked out of perfectly functional devices due to a forgotten Apple ID or a second-hand purchase that wasn't properly wiped.
The specific firmware version iOS 9.3.6 is the final release for the iPhone 4s. Because this device and software version are older, the security landscape is different from modern iPhones.
In this guide, we will explore the reality of bypassing iCloud on the iPhone 4s and the methods that actually work in 2024.
This removes the previous owner’s Apple ID entirely from Apple’s servers. You can sign in with your own Apple ID, use iMessage, FaceTime, iCloud backup, and the App Store normally. This is nearly impossible for an individual to do on iOS 9.3.6 without the original proof of purchase.
In the fast-paced world of smartphones, the iPhone 4s stands as a monument to a bygone era. Released in October 2011, it was the last iPhone designed under the direct supervision of Steve Jobs and the first to introduce the world to Siri. Fast forward to today, and while the iPhone has moved through a dozen more iterations, the 4s holds a peculiar status: it is a vintage device that, thanks to a surprising final software update, still sees niche use.
That update is iOS 9.3.6, released in July 2019. Long after Apple discontinued the iPhone 4s, they pushed out this critical update to fix GPS bugs and security vulnerabilities. For many users, this device became a perfect first smartphone for a child, a dedicated music player, a car GPS unit, or a nostalgic toy.
However, a vast number of these second-hand devices come with a digital padlock: iCloud Activation Lock. If the previous owner didn’t remove their Apple ID, the phone becomes a beautiful, glossy brick. This article dives deep into the technical landscape, legal realities, and step-by-step methodologies for bypassing iCloud on an iPhone 4s running iOS 9.3.6.
If you have an iPhone 4s running iOS 9.3.6 stuck on iCloud Lock, the solution depends on your goal:

Here’s an interesting feature idea for a tool or guide related to iPhone 4s on iOS 9.3.6 and iCloud bypass:
The iPhone 4s on iOS 9.3.6 is a zombie – technically alive, but missing its core function (telephony). An iCloud bypass on this device is a parlor trick: it proves the exploit works, but it does not restore full usability. If you need a phone, recycle it. If you want a nostalgia device for offline use, try the DNS method. Otherwise, the best iCloud bypass for the 4s is simply to contact the previous owner.
Note: Software and exploits change. What works today might be patched tomorrow – though Apple no longer updates iOS 9.3.6, so these methods will remain stable indefinitely.
, represents a unique chapter in Apple's security history. As the final supported firmware for this iconic device, iOS 9.3.6 serves as both a software cap and a frequent hurdle for users facing Activation Lock
. Bypassing the iCloud lock on this specific hardware is a complex intersection of technical exploits, hardware requirements, and significant functional trade-offs. The Technical Landscape
Unlike modern iPhones that rely on the Secure Enclave, the iPhone 4s is built on the
, which is vulnerable to older hardware-level exploits. For devices on iOS 9.3.6, the most common bypass methods involve: RAMdisk and Setup.app Removal
: This technique involves using a computer to "poke" the device's file system while in DFU (Device Firmware Update) mode . Tools like or specialized scripts are used to delete or rename
, the system application responsible for the initial activation screen. Hardware Requirements
: For iOS 9.3.x, a standard USB cable often isn't enough for a permanent "untethered" bypass. Many community-driven solutions require an Arduino Uno USB Host Shield
to send specific "checkm8-style" exploit pulses to the A5 chip to enter a "pwned" DFU state. DNS Redirection
: A simpler, non-permanent method involves changing the device's DNS settings
during Wi-Fi setup. This redirects the phone to a third-party server that mimics a home screen interface, allowing limited web browsing and app use without actually unlocking the system. Functional Limitations
Even a "successful" bypass is rarely a full restoration of the device. Users typically encounter severe restrictions: No Cellular Service
: Most bypasses "hacktivate" the device without a valid activation token from Apple's servers, meaning the SIM card will show "No Service," and calls or SMS will not work. iCloud Services
: Logging into a new iCloud account is often blocked. Features like iMessage, FaceTime, and Find My typically remain broken. Tethered vs. Untethered
: Some methods are "tethered," meaning the device will re-lock the moment it is restarted unless it is plugged back into a computer to run the exploit again. Ethics and Official Channels
While these methods are popular in the "legacy iOS" enthusiast community for salvaging e-waste, they operate in a legal gray area. Apple officially maintains that Activation Lock How to Bypass iCloud Activation Lock on iPhone 4s (iOS 9
is a theft-deterrent feature. The only manufacturer-approved way to remove the lock is through the original owner's credentials or by submitting proof of purchase Apple Support
In summary, bypassing an iPhone 4s on iOS 9.3.6 is a technical feat that transforms a "brick" into a limited media player or Wi-Fi-only device, but it cannot truly replicate the experience of an officially unlocked phone. needed to run these exploits?
The iPhone 4s is a legendary device, but getting stuck on the iCloud Activation Lock screen can turn this classic piece of hardware into a paperweight. If you have a 4s running iOS 9.3.6—the final update for this model—you might be looking for a way back in.
Here is everything you need to know about the current state of iCloud bypassing for the iPhone 4s on iOS 9.3.6. The Reality of iCloud Bypassing
Before diving in, it is important to understand that iCloud locks are a security feature designed by Apple to prevent theft. Bypassing this lock is not a "standard" procedure.
Official Method: The only permanent way to remove the lock is by using the original Apple ID and password or providing proof of purchase to Apple Support.
The Bypass: Most "bypass" methods for older hardware like the 4s involve using software exploits to jump past the setup screen.
Limitations: Bypassed devices often face "No Service" issues (SIM card won't work) and may lose access to iMessage or FaceTime. The DNS Bypass Method (No Computer Required)
This is the quickest way to use the device’s features (like the browser, maps, and music) without actually "unlocking" the phone system-wide. Restart your iPhone and select your Language and Country.
On the WiFi Selection screen, tap the "i" icon next to your network. Scroll down to DNS and select "Configure DNS."
Switch it to Manual and enter one of these IPs based on your region: USA: 104.154.51.7 Europe: 104.155.28.90 Asia: 104.155.220.58
Tap Back, connect to your WiFi, and wait for the "Activation Help" page to pop up. You can now use the device through this portal. Hardware-Based Exploits (Checkm8)
The iPhone 4s uses the A5 chip. Unlike newer models (iPhone 5s through X) that use the "checkm8" bootrom exploit, the 4s requires different tools.
Arduino + USB Host Shield: For a deep, "tethered" bypass on the A5 chip, many enthusiasts use an Arduino board to send an exploit (pwnedDFU) to the device.
Legacy Software: Tools like Sliver or various "Ramdisk" methods allow users to delete the setup.app file. This skips the activation process entirely.
Technical Skill: This requires a Mac (usually) and a high comfort level with terminal commands and DFU mode. Important Considerations
iOS 9.3.6 Stability: This version was released specifically to fix GPS issues. Using older bypass tools might cause system instability.
Data Security: Never enter sensitive personal data or your primary Apple ID into a bypassed device.
Ethical Use: These methods should only be used on devices you legally own but have lost access to. Conclusion
While the iPhone 4s on iOS 9.3.6 can be bypassed, it is rarely a "perfect" fix. For most, the DNS method provides enough functionality to use the phone as a media player. For those who want full system access, investing in an Arduino setup is the most reliable path for A5-generation devices. If you want to try the hardware-based route: Do you have access to a Mac or a PC? Are you comfortable using terminal commands? Do you own an Arduino Uno?
Tell me which method you prefer and I can walk you through the specific steps. If you want to use it as a
To bypass the iCloud Activation Lock on an iPhone 4s running iOS 9.3.6, you must use a hardware-based exploit. Because the iPhone 4s uses the A5 chip, standard software-only tools (like those used for newer iPhones) typically do not work. 🛠️ Hardware Requirements
The iPhone 4s has a unique USB controller that requires specific hardware to send the exploit commands. Arduino Uno: A standard microcontroller.
USB Host Shield: This must be soldered and stacked on top of the Arduino.
Mac or PC: Needed to run the bypass software after the exploit is sent.
30-pin USB Cable: The original charging cable for the iPhone 4s. 1. Prepare the Arduino
You must load the checkm8-a5 exploit onto your Arduino so it can communicate with the phone. Download the Arduino IDE. Install the USB Host Shield 2.0 library. Download the checkm8-a5 exploit source from GitHub.
Open the .ino file in the Arduino IDE and upload it to your board.
Note: You may need to solder the 3.3V and 5V jumpers on your USB Host Shield for it to power the iPhone correctly. 2. Enter Pwned DFU Mode
This step uses the Arduino to "pwn" the device, allowing custom software to run. Connect the iPhone 4s to the USB Host Shield. Put the iPhone into DFU Mode: Hold Home and Power for 10 seconds. Release Power but keep holding Home for 10 more seconds.
The Arduino LED will blink. When it stays solid or reaches the "Done!" state, the device is in Pwned DFU mode. 3. Run the Bypass Software
Once the device is "pwned," you use a computer to remove the activation screen. Connect the iPhone directly to your Mac or PC. For Mac: Use tools like Sliver 6.1 by AppleTech752. Select "A5 Devices" > "iPhone 4s" > "Delete Setup.app".
For Windows: Use tools like 3uTools or TunesKit Activation Unlocker to finish the process.
The device will reboot, skipping the activation lock screen. ⚠️ Important Limitations iPhone 4s FULL iCloud Bypass Tutorial
