iPhone 12 Jailbreak
iPhone 11 Jailbreak
From iOS 11 to iOS 11.4.1, there are online jailbreak tools and solutions available.
- Online Anzhuang
Anzhuang is the most popular online jailbreak app installer method in the world for iOS 11 to iOS 11.4.1. To install jailbreak apps, it has a dev code extraction method. Ru$za, a Russian hacker, discovered the dev code extraction method for the first time.
Then a Chinese hacking team named it Anzhuang. It does not have a direct link to install Anzhuang. You can get it from app stores like Cripzi, Pikzo, or Zee App.
Compatibility of the Device:
iPhone X, iPhone 8 Plus, iPhone 8, iPhone 7, iPhone 6S Plus, iPhone 6S, iPhone 6 Plus, iPhone 6, iPhone SE, iPhone 5S, iPad Pro (10.5-inch), iPad Pro (12.9-inch), iPad Mini 4, iPad Air 2, iPad Mini 3, iPad Pro (9.7-inch), iPad Pro (12.9-inch), iPod Touch 6.
To begin, download and install the zJailbreak app store on your iPhone, iPad, or iPod.
The Anzhuang app can then be found in the zJailbreak app store. Follow the on-screen instructions to finish installing the Anzuang app.
You must donate to install the above app stores because they are donateware. It was free to use with the Anzhuang installation method. However, the free method overlooks Anzhuang’s valuable function. As a result, installing a premium Anzhuang app is highly recommended.
- Online Velonzy
Another jailbreak app installation method for iOS 11 to iOS 11.4.1 devices is Velonzy. To install jailbreak apps, it employs the UDID registration method.
Velonzy supports the registration of user devices (UDID codes) in their database. Sign up and download Jailbreak IPAs to your computer. Then, using the Velonzy Jailbreak app installer, they can install these IPAs on their iOS 11+ device.
Velonzy includes a UDID submission process by default. To register your UDID with the Velonzy database, you can use a computer or an online method (using iOS 11.3 iPhone / iPad directly). We recommend registering the UDID on the Velonzy database online. It is less difficult than the Windows/Mac method.
Virtual Apricot Jailbreak
Apricot WebOS is designed specifically for iPhone devices. It provides iPhone users with a unique and uncommon OS experience as well as a virtual jailbreak experience. Apricot installs Cydia virtually using a unique UX design.
Some Apricot functions are more sophisticated than the standard Apple OS functions.
Apricot allows users to switch back to the default Apple iOS whenever they want. As a result, installing it is completely risk-free.
Apricot developers improved Apricot iOS compatibility from iOS 11 to iOS 11.4.1.
Apricot is a new way to experience the default of iOS 11 to iOS 11.4.1 any versions, as well as Mirror Apricot iOS of it. It’s a web-based process.
There is no other way to gain such experiences. You can virtually jailbreak any version of iOS from 11 to 11.4.1 Apricot web OS and install Cydia on Apricot.
It is also possible to use the Electra NO PC method with the Silzee Online JB app. Silzee can be downloaded from the zJailbreak, Xabsi, or iExtras 3rd party app stores.
The Electra team, in collaboration with Coolstar, has released the Electra 1.2.0 tool, which makes use of Ian Beer, Brandon Azad, and Tihmstar’s Exploits. All 64-bit devices running iOS 11 to iOS 11.4.1 are well supported. Using this tool, you can install Cydia, Sileo, and Electra Repo.
Along with hacker Sam Bingner, Pwn20wnd has released the Unc0ver tool v3.0.0 to jailbreak iOS 11 to iOS 11.4.1 running iPhone, iPad, or iPod. Dennis Bednarz and Samg is a Ninja who created the user interface. It is the Jailbreak that is semi-untethered.
It will install Cydia on your devices, allowing you to install additional jailbreak apps. Discover is more stable, according to the developers. The same tool can be used to jailbreak iOS 12 and later. Unc0ver jailbreak is available in both online and PC modes. However, completing the jailbreak online is the simplest option.
The main characteristics of the unc0ver jailbreak
- A single app can be accessed by all exploits.
- improved performance and stability
- Cydia’s performance has improved.
- Automatic restoration of the root filesystem
- There is no battery drain or slow down.
You can complete the unc0ver jailbreak without using a computer. Unc0ver Jailbreak can be downloaded from Cripzi, Xabsi, or iExtras.
To jailbreak iOS 11 to iOS 11.4.1 devices, use one of the computer-based jailbreak methods listed below.

He has already completed the exploit and obtained the kernel base. Tihmstar’s iOS 11.4.1 Jailbreak is without a doubt the work of a skilled Jailbreak developer. So, if your device is still running iOS 11.4.1, don’t upgrade; instead, stay on iOS 11.4.1. Tihmstar’s tweets about the iOS 11.4.1 jailbreak progress are listed below.
- Code4iOS has achieved a new iOS 11.4.1 / 11.4 jailbreak.
A crash log from the iOS 11.4.1 jailbreak has been tweeted by James Seeley / @Code4iOS. This is used in several jailbreaks, including the Electra, Unc0ver, and Meridian. He also encouraged people to try the jailbreak.
He also stated that he created Code4iOS for the general public as a tool for customizing and securing their devices, and that his website contains iOS Configuration Profiles that are signed with the Code4iOS Profile Signing Certificate.
GeoSn0w / @FCE365, a well-known iOS security researcher, is interested in this and has posted a video about it on YouTube. He had already messaged Code4iOS to request more information, but had received no response from this developer. However, he advises you to avoid attempting this iOS 11.4.1 jailbreak until he confirms its legitimacy.
- Zlabs Team iOS 11.4.1 Jailbreak
The JailbreakMe UEF jailbreak for iOS 11.4.1 has been announced by the Zlabs team. Still, they have not released the IPA, and the Project has posted to GitHub that it will be available soon. This is compatible with all iOS versions from 11.4 to 12.0.1.

Tinlin, the Vietnam champion U23 Asia, tweeted that a zero jailbreak for iOS 11.4.1 and iOS 11.4 would be available soon. They’ve been talking about their jailbreak tool since iOS 11.2 versions. They are newcomers to the Jailbreak Community because there is little information about them.
- Ian Beer, as promised, has made the iOS 11.4.1 exploit available to the public.
Ian Beer announced the IOS 11.4.1 exploit a month ago and, as promised, released it to the public. It consists of the following iOS security flaws.
UaF in the kernel
Kernel information leakage exploit
Sandbox escape method
However, these bugs are not powerful enough for an iOS 11.4.1 jailbreak, but they may be useful in the future when combined with other public exploits.
These exploits, according to Jake James, an iOS jailbreak tweak developer, do not grant root access, which is required for the jailbreak.
- Ian Beer (@i41nbeer) discovered iOS 11.4.1 vulnerabilities.
Ian Beer discovered iOS 11.4.1 exploits, which will be released soon. He will almost certainly upgrade to iOS 12. According to his tweet, both iOS 11.4.1 and iOS 12 jailbreaks with the Electra tool are possible.

- FilzaEscaped / FilzaJailed for iOS 11.3.1
FilzaJailed iOS file manager has recently been updated from iOS 11.3.1 to iOS 11.2 versions. There is no jailbreak method for gaining full root access to all files in the directory. FilzaEscaped was created by Bas vT / @AppleDry05. FilzaJailed / FilzaEscaped can be downloaded from this page.
- iOS 11.3.1 RootlessJB
Jake James has released a new jailbreak concept called RootlessJB. It is not a system-rooted jailbreak that installs Cydia. It enables you to install Cydia tweaks on iOS 11.3.1 to iOS 11.2 using the free Filza and ZipApp.
- The Phoenix Dev Team has published a Safari exploit for iOS 11.3.1.
Niklaus Baumstark published a browser-based Safari exploit for iOS 11.3.1. Safari exploits the CVE-2018-4233 WebKit bug, which is based on Ian Beer’s tfp0 exploit. Niklaus Baumstark is a Phoenix Dev Team member. Previously, this team discovered bugs in Safari and took part in Pwn2Own 2018.
However, these bugs have been fixed in iOS 11.4 versions.

He also uploaded a demonstration video to the Chinese site. Zhao demonstrates Mobile Terminal running with root access on an iOS 11.3.1 device before launching Cydia. However, there is no word on a public release date.
Watch the video below by @S0rryMyBad.
- Spark and Bxl’s iOS 11.3.1 Jailbreak:
Min(Spark) Zheng and Xiaolong Bai (@bxl1989) have successfully jailbroken iOS 11.3.1. They have posted a demonstration video of iOS 11.3.1 on YouTube as well as the official Twitter page. Spark had previously successfully jailbroken the iOS 11.3 version. Even though Spark owns the OverSky jailbreak, he has never made it public. As a result, this will almost certainly be a private jailbreak as well.
- Jailbreak Keen iOS 11.3.1:
Tencent Keen Security Lab’s Liang Chen and Marco Grassi demonstrated the Semi-Untethered jailbreak capability of iOS 11.3.1. At the Infiltrate Security Conference 2018, they successfully jailbroke iOS 11.3.1 using an iPhone X.
Liang Chen also used his official Twitter account to share one of the screenshots of Cydia on iOS 11.3.1.
However, no mention has been made of the public release of Keen IPA to jailbreak iOS 11.3.1. Keen Lab previously demonstrated iOS 11.1.1, iOS 11, and iOS 10.3.2. At the same time, they did not release the Keen jailbreak method, which was used to jailbreak iOS 11.1.1, iOS 11, and iOS 10.3.2.
- Memory corruption problem with Ian Beer (CVE-2018-4206)
The Memory corruption issue on iOS 11.3 running iPhone 5s and later, iPad Air and later, and iPod Touch 6th generation was discovered by Ian Beer, who brought us the iOS 11- iOS 11.1.2 exploit for potential Jailbreak. He disclosed the vulnerabilities that exist on both iOS and MacOS. He made the exploit’s proof-of-concept information public. We anticipate that this will be developed as an iOS 11.3 Jailbreak tool, similar to the previous Electra Jailbreak.
However, Apple patched these vulnerabilities with the release of iOS 11.3.1.
- Jailbreak iOS 11.3 Min (Spark) Zheng
As we all know, Min Zheng’s iOS 11.3 jailbreak is still in the works. Here is the most recent information on the status of the iOS 11.3 jailbreak. He tweeted that he had successfully jailbroken iOS 11.3 and shared a screenshot of the Cydia configuration.
However, given his track record, we cannot expect a public release of the OverSky iOS 11.3 jailbreak, whether it is a genuine iOS 11.3 jailbreak or not.
Min Zheng (Alibaba security team) gained root shell access on iOS 11.3. Obtaining root access leads to a potential jailbreak and brings us one step closer to an iOS 11.3 jailbreak.
Previously, he discovered a zero-day bug and a kernel bug in iOS 11.3 versions that allow the attacker to execute unsigned code with kernel privileges. These flaws affected iOS 11.2.6 and earlier versions as well. That means you can still jailbreak these versions, and we can keep hoping for an iOS 11.3 jailbreak. You should also prepare your device for a future jailbreak or semi-jailbreak release. It is advised to save SHSH Blobs for the iOS 11.3 version.
- A number of bugs have been fixed in iOS 11.2.6 and iOS 11.2.5.
iOS 11.2.6 and 11.2.5 updates are more stable than iOS 11.2. A number of bugs have been fixed in iOS 11.2.6 and iOS 11.2.5. According to jailbreak experts, rooting iOS 11.2.6 and iOS 11.2.5 is more difficult than rooting iOS 11.2, iOS 11.2.1, and iOS 11.2.2. That is because it has many vulnerabilities in iOS 11.2 to iOS 11.2.2 versions, which Apple patched with iOS 11.2.6 and iOS 11.2.5 updates. In brief, here are the details on bug fixes.
Google’s Russ Cox has a memory corruption problem (CVE-2018-4082)
The memory corruption issue was discovered by Russ Cox in iOS 11.2 – iOS 11.2.2 running on iPhone 5S and later, iPad Air and later, and iPod touch 6th generation. This vulnerability allows arbitrary code to be executed with kernel privileges. This is the most important aspect of developing a jailbreak tool. However, Russ Cox reported this bug to Apple, and it was fixed in the iOS 11.2.5 update.
Memory corruption vulnerability discovered by Rani Idan of the Zimperium zLabs Team (CVE-2018-4087/CVE-2018-4095)
Rani reported memory corruption issues as a result of arbitrary code execution with system privileges. The problem affects iOS 11.2 to iOS 11.2.2 devices running iPhone 5S and later, iPad Air and later, and iPod touch 6th generation. This is a privilege to a possible jailbreak.
Aside from the major issues listed above, the following bugs have been reported.
Jann Horn of Google Project Zero CVE-2018-4090
CVE-2018-4094: Mingi Cho, MinSik Shin, Seoyoung Kim, Yeongho Lee, and Taekyoung Kwon of Yonsei University’s Information Security Lab.
CVE-2018-4092: Antid0te’s Stefan Esser AND
Abraham Masri (@cheesecakeufo) CVE-2018-4100
Ret2 Systems Inc. collaborates with Trend Micro’s Zero Day Initiative to address CVE-2018-4085.
CVE-2018-4086: Netflix’s Ian Haken
CVE-2018-4096: discovered by OSS-Fuzz
All of these bugs, however, have been fixed by the iOS 11.2.5 update. It is mentioned in the “About Apple security content of iOS 11.2.5” section.
Even though these are fixed in iOS 11.2.5, the bugs mentioned above remain in iOS 11.2 to iOS 11.2.2 firmware. As a result, jailbreaking iOS 11.2 – iOS 11.2.2 versions is simple. This is due to the Sandbox escape attribute, which is required to create a jailbreak tool. So we can keep our fingers crossed for an untethered or semi-tethered jailbreak for iOS 11.2 – iOS 11.2.2 rather than iOS 11.2.5 & iOS 11.2.6.
- iOS 11.2.2 Vulnerabilities are released by Zimperium zLabs.
Rani Idan, a member of the Zimperium zLabs security team, has published two iOS vulnerabilities that could lead to jailbreak. They discovered the following vulnerabilities, which are currently active on iOS 11.2 / iOS 11.2.1 / iOS 11.2.2.
CVE-2018-4095 – Bluetoothd memory corruption.
CVE-2018-4087 – Unauthorized code execution on various critical daemons.
Previously, Adam Donenfeld of Zimperium zLab released a fully chained iOS kernel exploit (ziVA) that works on all iOS devices running iOS 10.3.1 and is suitable for iOS 10.3.1 jailbreak.
According to Rani, they reported these bugs to Apple, who fixed them with the iOS 11.2.5 update. Rani, on the other hand, promised to publish more information about the research process and technical write-up, as well as the full exploit source code. He thanked Apple, the zLabs team, and Nikias Bassen (@pimskeks) for their assistance throughout the project.
Sandbox escape is an important part of the jailbreak process. If they make this an open source code project, jailbreak experts will undoubtedly be able to develop it to the point of Jailbreak. However, we recommend that you follow the steps below as soon as iOS 11.2 Jailbreak is available.
Downgrade to iOS 11.2 – iOS 11.2.2 on your device.
SHSH Blobs should be saved for your device.
If you are running iOS 11.2.2 or lower, do not upgrade your device.
- Kernel exploit by Russ Cox
Rumor has it that:
Google Security Researcher Russ Cox discovered the new Kernel Exploit for iOS 11.2. After Ian Beer released the iOS 11 – iOS 11.1.2 exploit, many jailbreak tools for iOS 11 appeared, and everyone anticipates that it will hit iOS 11.2 Jailbreak using this kernel exploit.
It will work on iPhone 5S and later, iPad Air and later, and iPod touch 6 devices running iOS 11.2, 11.2.1, and 11.2.2, according to the Russ Cox Kernel exploit support list. As a result, some jailbreak experts advise you to prepare for the iOS 11.2 to iOS 11.2.2 jailbreak.
Furthermore, according to rumors, Russ Cox has not yet released the exploit to the public and has stated on his official Twitter account that he intends to do so soon.
Russ Cox claims that:
However, Russ Cox stated that he did not release any kernel exploits and only reported the bugs. The screenshot of his tweet is below.
He is completely correct, as evidenced by Apple’s Security content. This vulnerability was discovered in iOS 11.2.5 and patched by Apple. Here’s a screenshot of Apple’s iOS 11.2.5 security content.
However, there is still the possibility of jailbreaking iOS 11.2 because the bug remains the same for iOS 11.2 versions, as this was patched in iOS 11.2.5.
It is preferable to stay on iOS 11.2 – iOS 11.2.2 rather than updating to iOS 11.2.5.
Exploiting async awake at the kernel level
Google security researcher Ian Beer discovered this tfp0 exploit for Google’s Project Zero. For the first time, that exploit was made available for iOS 11 and higher versions, and many developers released jailbreak tools for iOS 11 and higher versions based on it.
Using this exploit, many hackers are currently working on releasing untethered or semi-tethered jailbreaks for iOS 11.2 to iOS 11.2.2.
