The IMEI is a 15-digit number hardcoded into your iPhone’s baseband processor (the chip responsible for cellular communication). It is not stored in the user-accessible operating system (iOS). It is stored in the Secure Enclave of the baseband firmware.
When you jailbreak your iPhone, you only gain root access to the User Partition (iOS). You do not gain access to the Baseband Processor. Apple and Qualcomm/Intel have designed the iPhone so that the baseband runs its own real-time operating system (RTOS) that is cryptographically isolated from iOS.
In the past, specifically for iPhone 4 and 4S (and to a limited extent the 5/5C), hardware devices known as "IP-Boxes" or specialized JIG programmers were used. These tools physically interfaced with the baseband chip (e.g., Qualcomm MDM6610) to rewrite the EEPROM (Electrically Erasable Programmable Read-Only Memory).
For the advanced users who want to know why you can’t just run a command:
When a user restores iOS via iTunes, the Baseband Firmware (BBFW) is updated. The Baseband Firmware interacts with the secure memory where the IMEI resides. While hackers have historically found vulnerabilities in the baseband firmware (e.g., ultrasn0w unlock), these exploits generally allowed for network unlocking (allowing the use of other SIM cards) rather than IMEI rewriting.
Changing the IMEI (International Mobile Equipment Identity) of an iPhone—whether jailbroken or not—is not possible through software and is illegal in many jurisdictions. Why You Cannot Change an iPhone IMEI
The IMEI is a unique 15-digit identifier hardcoded into the device's baseband hardware (the cellular modem). Unlike Android devices, where certain "IMEI repair" tools exist for specific chipsets, Apple’s security architecture (Secure Enclave and hardware-linked identifiers) prevents software-based modification of this ID. Hardware Lock:
The IMEI is tied to the physical logic board. The only way to "change" it is to physically replace the motherboard with one from a different device. Jailbreaking Limits:
Jailbreaking grants "root" access to the iOS operating system to customize themes or install unofficial apps, but it does
provide access to the write-protected firmware of the cellular modem where the IMEI resides. Security Risks:
Most websites or YouTube videos claiming to offer "IMEI Changers" for iPhone are
. They often contain malware or phishing links designed to steal your Apple ID credentials. Legal and Practical Risks
In many countries (such as the UK and US), altering or "spoofing" an IMEI is a criminal offense under telecommunications laws. Carrier Blacklisting:
If you are trying to change an IMEI because the device is "blacklisted" (reported lost or stolen), changing the ID will not help. Carriers track devices via a centralized database; a blacklisted phone generally cannot be used on any major network. Permanent Damage:
Attempting to flash unofficial modem firmware can "brick" your iPhone, permanently disabling all cellular, Wi-Fi, and Bluetooth functionality. Legitimate Alternatives
If your goal is to use a phone that is locked or restricted, consider these legal paths: Carrier Unlock:
Contact the original carrier to request an official unlock if the contract is paid off. Device Trade-in: Apple Trade In program
to exchange your current device for credit toward a new one. Check Blacklist Status: Use a reputable service like CTIA’s Stolen Phone Checker
to verify if a used device you purchased has a clean record. Are you trying to bypass a carrier lock , or are you looking for a way to use a different SIM card?
Changing the IMEI (International Mobile Equipment Identity) of an iPhone is not possible through standard jailbreaking and is illegal in many jurisdictions. The Reality of IMEI Changing
Hardware Locked: The IMEI is hardcoded into the iPhone's hardware (specifically the baseband chip) during manufacturing. It is a permanent identifier, similar to a digital fingerprint.
Jailbreaking Limitations: While jailbreaking removes software restrictions to allow customization, it does not grant access to rewrite the hardware-level identifiers on modern iPhones.
Legal Risks: Altering an IMEI is considered a criminal offense in many countries, including the US, UK, and Canada, as it is often used to mask stolen devices or bypass blacklists.
Identity Masking: Even if you could "spoof" the IMEI locally, mobile networks identify your device through multiple other hardware signatures, making it nearly impossible to remain untraceable by only changing the IMEI. Technical Myths vs. Reality
Some older tools or "clones" might claim to change the IMEI, but these are often scams or outdated methods that no longer work on modern iOS versions:
ZiPhone: An extremely old tool (dating back to original iPhones) that had limited success with IMEI manipulation, but it is entirely incompatible with modern devices.
"IMEI Changer" Apps: Most "APK" or "IPA" files claiming to change your IMEI are malicious software designed to steal data or install malware.
Terminal Commands: Commands like nvram wifiaddr= only change the Mac address of the Wi-Fi chip, not the cellular IMEI.
If your device is blacklisted or locked, the most reliable and legal solutions are to contact your carrier for an official unlock or purchase a device with a clean history.

The idea of changing an on an iPhone via jailbreaking is a common topic in tech circles, but it's important to separate the myths from reality. While jailbreaking can unlock many features, changing an IMEI is a complex, often illegal, and mostly outdated process. The Reality of IMEI and Jailbreaking What is an IMEI?
It is a unique 15-digit number that identifies your device on a cellular network. Hardware vs. Software:
On modern iPhones, the IMEI is deeply embedded in the hardware (the baseband). Jailbreaking only modifies the software layer (iOS), which typically does not allow for a permanent change to the hardware-level IMEI. Outdated Tools: You may see references to tools like Gevey SIMs change imei iphone jailbreak
, but these are largely ineffective on any device newer than the iPhone 4 or 4S. Why People Consider It Bypassing Blacklists:
The primary reason users attempt an IMEI change is to use a device that has been blacklisted or banned by a carrier.
Some users believe changing the IMEI can prevent tracking by third parties or law enforcement. Development and Testing:

The Reality of Changing Your iPhone's IMEI (Even with a Jailbreak)
If you’ve been scouring the web for a way to change your iPhone’s IMEI (International Mobile Equipment Identity)
using a jailbreak, you’ve likely run into a wall of conflicting information. The short answer is:
You cannot truly change an iPhone’s IMEI through software alone, including jailbreaking.
While jailbreaking grants you root access to the iOS file system, the IMEI is hard-coded into the device’s hardware—specifically the baseband chip—making it virtually impossible to alter permanently without specialized (and often illegal) hardware tools.
Here is the breakdown of why this is a hot topic and what you need to know before you try. 1. Hard-Coded Hardware Security
The IMEI is a unique 15-digit serial number used by carriers to identify valid devices on their networks. On iPhones, this identifier is stored in a secure, "read-only" section of the hardware. Jailbreaking
modifies the operating system (iOS) to allow unauthorized apps. Hardware IDs exist outside the scope of what iOS can modify.
Even with a "tweak" that claims to change your IMEI, you are likely only performing an IMEI Spoofing trick. This makes the think the ID is different, but the cellular modem
will still broadcast the original hardware ID to the carrier. 2. The Dangers of "IMEI Changer" Apps
If you see an app in Cydia or Sileo claiming to change your IMEI, proceed with extreme caution. Malware Risks:
Many tools claiming to offer this "forbidden" feature are actually designed to steal your data or install spyware. System Instability:
Messing with baseband files can permanently "brick" your iPhone’s cellular capabilities, turning it into an expensive iPod.
Be wary of websites asking for money to "remotely" change your IMEI via jailbreak. These are almost always fraudulent. 3. Legal and Ethical Red Flags
In many jurisdictions, including the US, UK, and EU, tampering with an IMEI is a criminal offense
. This is because changing an IMEI is a common tactic used to bypass "blacklists" on stolen phones. Carrier Blacklists:
If a phone is reported stolen, its IMEI is added to a global database, preventing it from connecting to any network. Network Bans:
If a carrier detects IMEI tampering, they can permanently ban the device and even the account holder. 4. Better Alternatives for Your Jailbroken Device
If your goal is privacy or avoiding tracking, there are better ways to use your jailbreak without risking your hardware: Location Spoofing: Use tweaks like AkLocationX to hide your GPS position. UDID Masking:
Some tweaks can mask your Unique Device Identifier (UDID) for specific apps, which helps with privacy. MAC Address Randomization:
iOS does this natively, but jailbreak tweaks can give you more control over your Wi-Fi identity. The Bottom Line
Jailbreaking is great for customization and new features, but it isn't magic. Changing an iPhone IMEI is not a software-based task.
If you have a blacklisted phone, the only legitimate way to fix it is to contact the carrier to resolve any underlying billing or ownership issues. Are you looking to bypass a carrier lock or just trying to improve your privacy on a jailbroken device? Disclaimer:

Changing the IMEI (International Mobile Equipment Identity) of an iPhone is a highly complex task that is illegal in many countries The IMEI is a 15-digit number hardcoded into
and technically restricted by Apple's hardware design. While jailbreaking provides deeper access to the iOS file system, it does not easily allow for a permanent IMEI change because this identifier is typically hard-coded into the device's baseband hardware. Apple Support Community Legal and Safety Risks Before attempting any modification, consider the following: Legal Consequences
: In many regions, including the UK and India, altering an IMEI is a criminal offense punishable by fines or imprisonment. Device Bricking
: Amateur attempts to modify the baseband or system files can permanently disable your iPhone's ability to connect to any cellular network. Warranty and Security : Any such modification voids your Apple Warranty and leaves your device vulnerable to security exploits. Why Jailbreaking Isn't Enough
Jailbreaking allows you to install "tweaks" and access the root file system, but the IMEI is stored in the Baseband Processor (BP) , not the Application Processor (AP) where iOS runs. Apple Support Community
The concept of changing an iPhone's International Mobile Equipment Identity (IMEI) through a jailbreak is a topic fraught with technical complexity and significant legal risks. While many users seek this to bypass network blacklists or enhance privacy, modern iOS architecture has made it virtually impossible to permanently alter this unique identifier. The Reality of Changing iPhone IMEI
In 2026, it is widely considered impossible to permanently change an iPhone’s IMEI through software alone. Unlike some Android devices with more open hardware architectures, Apple’s security is deeply integrated into the device's logic board.
Hardware Hard-Coding: The IMEI is burned into the phone's physical hardware during manufacturing. It functions like a device's "digital DNA".
Baseband Security: The IMEI lives within the NVRAM for the baseband firmware, which is protected by specialized security protocols that even a jailbreak cannot easily override.
The Only Permanent Method: The only legitimate way a device's IMEI changes is through a physical replacement of the motherboard. Can Jailbreaking Help?
Jailbreaking removes software restrictions placed by Apple, allowing you to install third-party apps and customize system-level settings. However, its relationship with IMEI modification is often misunderstood. iPhone Motherboard FAQs
Yes. Because the Apple server recognizes your iPhone by Serial Number and IMEI. The serial number and IMEI are on the motherboard. iphone-repair.my
Changing an iPhone's International Mobile Equipment Identity (IMEI) via jailbreaking is technically complex, restricted to legacy devices, and generally considered illegal in most jurisdictions. Technical Feasibility and Limitations
The IMEI is a 15-digit unique identifier hardcoded into an iPhone's baseband hardware (modem) during manufacturing.
Changing an iPhone's IMEI number, especially on modern devices (iPhone X and newer), is generally impossible through software or jailbreaking, as it is a permanent hardware identifier.

Changing the IMEI (International Mobile Equipment Identity) of an iPhone is generally not possible on modern devices, even with a jailbreak. The IMEI is a unique hardware identifier hardcoded into the device's baseband chip, which is separate from the main operating system (iOS). Technical Reality
Hardware Lock: On all modern iPhones (iPhone 6 and newer), the IMEI is stored in secure, read-only sections of the baseband hardware. Jailbreaking only grants root access to the iOS software, not the deep firmware controlling the cellular modem.
Outdated Methods: You may see references to tools like ZiPhone or Gevey SIMs, but these only worked on the original iPhone and iPhone 3G. They are entirely incompatible with any recent iOS version or hardware.
Logic Board Replacement: The only way to truly "change" an IMEI is to physically replace the phone's logic board with a new one that has a different registered IMEI. Risks and Legality
⚠️ Legality: In many countries, including the UK and parts of the US, altering an IMEI is illegal under laws designed to prevent the resale of stolen devices.
Permanent Damage: Attempting to use unverified software tools to "flash" your baseband can permanently brick your phone's ability to connect to any cellular network.
Security Risks: Many "IMEI changer" apps found online are actually malware or scams designed to steal your personal data once you grant them root access through a jailbreak. Common Alternatives
If you are trying to change your IMEI for a specific reason, there may be a safer solution:
Network Unlock: If you want to use a different carrier, you can often request an official unlock from your current provider or use a legitimate third-party service.
Blacklisted Device: If your phone was reported lost or stolen, it is blacklisted globally. Changing the IMEI will not solve this legally; your best option is to contact the original owner or carrier to resolve the status.

Changing the IMEI (International Mobile Equipment Identity) of an iPhone is not a standard feature
of jailbreaking, and for most modern iPhones, it is effectively impossible through software alone. The IMEI is a hard-coded identification number tied to the device's hardware (the baseband chip).
While jailbreaking grants root access to the iOS file system to customize themes or install unofficial apps, it does not typically provide the low-level access required to rewrite the hardware-level IMEI. Key Realities of IMEI Modification Hardware Lock
: On all modern iPhones, the IMEI is stored in a secure, read-only portion of the baseband processor. Standard jailbreak tools like do not have the capability to modify this. Legacy Tools
: In the very early days of iPhone (iPhone 2G/3G), tools like
claimed to modify the IMEI, but these methods were patched by Apple over a decade ago and do not work on newer devices. Legal Risks
: In many jurisdictions, including the UK and parts of the US, changing or tampering with an IMEI is illegal and can lead to criminal prosecution. Blacklisting
: Changing an IMEI is often sought to bypass "blacklisted" status (reported stolen). Carriers use global databases to track these numbers; even if a software spoofing tool existed, the network would likely still identify the original hardware. Verification & Scams If you see websites or videos (especially on platforms like
) claiming to change the IMEI of an iPhone 11 or newer via a "jailbreak tool," these are almost universally
. They often lead to malware or "human verification" surveys that steal personal data. To verify your current IMEI, you can dial in the Phone app or check Settings > General > About Are you trying to resolve a network lock blacklisted device
I understand you're asking about changing the IMEI on a jailbroken iPhone. However, I need to be clear:
Changing or tampering with a device's IMEI number is illegal in most countries, as IMEI is a hardware-bound identifier used for tracking stolen phones, network authentication, and emergency services. Modifying it can be considered fraud or a criminal offense.
If you're looking to:
If your interest is purely technical (e.g., studying baseband security), research within legal boundaries using development devices and sandboxed environments, never with production IMEIs.
If you need help with any legal post-jailbreak modifications (like bypassing iCloud lock with owner’s consent using official tools), let me know and I can guide you appropriately.
Changing your iPhone's IMEI number via jailbreak is widely considered impossible to achieve permanently and is illegal in most jurisdictions. While some legacy tools and "RAM spoofing" methods exist, they do not change the actual hardware identifier. The Technical Reality of IMEI Modification
The IMEI is hardcoded into the iPhone's baseband/modem chip during manufacturing. Because it is stored in read-only memory (ROM), software-based modifications—even with root access from a jailbreak—cannot permanently rewrite it. Can You Change Your IPhone IMEI? Unveiling The Truth - Ftp
I understand you're looking for content related to changing the IMEI on a jailbroken iPhone. However, I need to provide some important context first.
Changing or altering the IMEI number of any mobile device is illegal in most countries, as the IMEI is a permanent hardware identifier used by carriers and law enforcement to track stolen devices, block blacklisted phones, and ensure network security. Modifying it can constitute fraud, tampering with evidence, or circumventing lawful restrictions.
What legitimate alternatives exist (and are often confused with IMEI changing):
If you're writing an informational/educational article (e.g., for a security blog), consider focusing on:
If you've lost your IMEI after a bad flash or jailbreak, solutions involve restoring the original identifier via factory firmware or professional repair – not changing it to a different number.
It is possible for a jailbreak tweak to modify how the OS displays the IMEI in the Settings menu (Settings > General > About). This is merely a UI spoof; it changes the string of text the user sees but does not change the identifier broadcasted to the cellular tower.
