Relaxin 0.4.5 is a major update to the RootHide-based, semi-untethered jailbreak project for modern iPhones and iPads. The new release expands the supported firmware range to iOS and iPadOS 16.5.1, 16.6 and 16.6.1 while retaining support through iOS 17.3.1 on compatible hardware. It also includes important stability improvements designed to reduce crashes and kernel panics. (Relaxin)
Relaxin is associated with OwnGoal Studio and contributors including Lakr233, 82Flex and the RootHide community. The official Relaxin project describes it as a RootHide semi-untethered jailbreak based on work from Dopamine and its RootHide fork. (Relaxin)
What Is Relaxin Jailbreak?
Relaxin is an app-based jailbreak that provides a modern RootHide-oriented jailbreak environment instead of using the traditional rootful architecture found in many older jailbreak tools.
It is semi-untethered, meaning the jailbroken state does not remain active after a complete reboot. The Relaxin app remains installed, but you must launch it and perform the jailbreak again to reactivate the jailbreak environment.
Relaxin is currently distributed as public-beta software, so users should expect the possibility of bugs, exploit failures and occasional instability. (Relaxin)
Relaxin 0.4.5: What’s New?
The headline improvement in Relaxin 0.4.5 is expanded iOS 16 support.
The release adds compatibility with iOS and iPadOS 16.5.1, 16.6 and 16.6.1 while maintaining the project’s existing iOS 17 support window through iOS 17.3.1. (Relaxin)
Relaxin 0.4.5 also addresses two problems that could trigger kernel panics while launching processes and includes additional reliability improvements. These changes make the release particularly important for users who experienced instability with previous Relaxin builds. (Relaxin)
Relaxin 0.4.5 Compatibility
The current Relaxin 0.4.5 compatibility window is iOS and iPadOS 16.5.1 through 17.3.1 on supported hardware.

iOS 17.2: Supported
iOS 17.2.1: Supported
iOS 17.3: Supported
iOS 17.3.1: Supported
iOS 17.4 and newer firmware should not be assumed compatible with the current Relaxin exploit chain. The project’s published compatibility information currently ends at iOS 17.3.1. (Relaxin)
Relaxin Supported Devices
Current Relaxin 0.4.5 information identifies support across A12 through A17-class hardware as well as selected Apple Silicon iPads using M1 and M2 chips. (Relaxin)
This potentially covers several generations of iPhone and iPad, including devices from the iPhone XS generation through the iPhone 15 series, depending on the exact processor and installed firmware.
Compatibility should always be checked using both the device processor and exact iOS version. Two iPhones running the same firmware can have different jailbreak capabilities because Apple security mitigations vary between chip generations.
A12 Devices
A12 hardware includes devices such as the iPhone XS, iPhone XS Max and iPhone XR.
Support for earlier processor generations was expanded during later Relaxin development, and current v0.4.5 compatibility information includes A12-class hardware within the supported range. (Relaxin)
A13 Devices
A13 hardware includes the iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max and iPhone SE second generation.
These devices fall within the broader hardware range associated with current Relaxin releases when running supported firmware.
A14 Devices
A14 hardware includes the iPhone 12 mini, iPhone 12, iPhone 12 Pro and iPhone 12 Pro Max.
Users should still confirm their exact firmware before installing Relaxin because hardware support does not override the iOS compatibility window.
A15 Devices
A15 devices include the iPhone 13 series, iPhone SE third generation, iPhone 14 and iPhone 14 Plus.
A15 and newer devices were an important focus of the original Relaxin public-beta project, particularly for iOS 17. (Relaxin)
A16 Devices
A16 hardware includes the iPhone 14 Pro, iPhone 14 Pro Max, iPhone 15 and iPhone 15 Plus.
These devices are included within the supported modern hardware range when running compatible firmware.
A17 Pro Devices
The iPhone 15 Pro and iPhone 15 Pro Max use the A17 Pro processor.
Relaxin development specifically targeted modern Apple security environments that made conventional jailbreak techniques significantly more difficult on newer hardware.
M1 and M2 iPads
Relaxin 0.4.5 compatibility information also includes supported M1 and M2 iPad hardware. (Relaxin)
Because multiple iPad models share similar names while using different processors, identify your exact model and chip before attempting the jailbreak.
Relaxin RootHide Architecture
Relaxin uses a RootHide-oriented architecture rather than behaving like a traditional rootful jailbreak.
RootHide builds on the modern rootless jailbreak model while placing additional emphasis on isolating and hiding jailbreak-related components from ordinary applications.
This architecture can improve compatibility with applications that dislike modified environments, but it should never be treated as a guarantee that banking, gaming or streaming applications cannot detect a jailbroken device.
Jailbreak-detection systems change frequently and can use many different techniques.
RootHide vs Rootless
Rootless jailbreaks avoid directly modifying Apple’s sealed system partition.
Instead, jailbreak packages, libraries and tweaks operate through separate writable locations and modern bootstrap environments.
RootHide extends this concept with additional isolation and hiding mechanisms.
As a result, older jailbreak tweaks designed only for traditional rootful environments may not work directly with Relaxin.
Always confirm that a tweak supports RootHide or the relevant rootless environment before installing it.
Semi-Untethered Jailbreak Explained
Relaxin is semi-untethered.
After successfully jailbreaking, you can use the jailbreak normally without leaving your iPhone connected to a computer.
However, completely rebooting the device disables the active jailbreak state.
Your installed jailbreak environment normally remains on the device, but tweaks and jailbreak services stay inactive until Relaxin successfully performs the jailbreak again.
After rebooting, open Relaxin and use its jailbreak function to restore the active environment.
Relaxin and Sileo
Relaxin can bootstrap a modern package-management environment that includes Sileo.
Sileo allows users to browse jailbreak repositories, install tweaks, update packages and manage installed jailbreak software.
Once Relaxin completes its jailbreak setup, Sileo should become available as part of the environment.
Only add repositories you trust. Jailbreak packages can execute with significantly greater privileges than ordinary App Store applications.
Relaxin Exploit Architecture
Relaxin combines several modern exploit techniques and jailbreak components rather than depending on one single vulnerability.
The project has discussed kernel read/write techniques, GPU-related primitives and modern page-protection bypass research used to gain the capabilities necessary for a complete jailbreak.
Relaxin development also attracted attention because its developers publicly discussed using AI-assisted reverse-engineering and development workflows.
The exact exploit chain can evolve between builds, so old descriptions should not automatically be assumed to represent every future Relaxin release.
Relaxin Lite Explained
Relaxin Lite is a separate experimental concept that has circulated alongside the main Relaxin jailbreak project.
It has been discussed in connection with browser and WebKit-based demonstrations intended to explore whether parts of an exploit chain can be initiated through a browser-style environment.
Relaxin Lite should not be confused with the standard Relaxin 0.4.5 IPA jailbreak.
The regular Relaxin application remains the appropriate option for users who want the complete supported jailbreak environment.
Experimental browser demonstrations may be useful for security research, but they should not be advertised as equivalent to a fully supported one-click online jailbreak unless the developers explicitly release them as such.
Relaxin 0.4.5 Download
Download Relaxin from the official project source whenever possible.
Avoid random websites claiming to provide special Relaxin editions, modified jailbreak IPAs or browser-based versions with additional firmware support.
[DOWNLOAD RELAXIN 0.4.5 IPA]
Official Relaxin website:
The official project page provides project information and should be treated as the primary reference point for supported releases and compatibility. (Relaxin)
Relaxin IPA and TIPA Files
Relaxin may be distributed in IPA or TIPA-style packages depending on the intended installation method.
An IPA is the normal application archive used by sideloading utilities such as Sideloadly, ESign and KSign.
A TIPA package is commonly associated with TrollStore distribution.
Always obtain the package from a trusted source and avoid unnecessarily modified releases.
Best Way to Install Relaxin
The best installation method depends on your firmware.
TrollStore is the preferred option whenever your particular iOS version already supports TrollStore because it can keep compatible applications persistently signed.
Sideloadly is a convenient computer-based alternative.
ESign and KSign can provide on-device IPA installation when you have an appropriate signing certificate.
Installing Relaxin and successfully jailbreaking the device are two separate processes. An IPA signing method does not add jailbreak compatibility to unsupported hardware or firmware.
How to Install Relaxin With TrollStore
[DOWNLOAD RELAXIN TIPA]
[OPEN TROLLSTORE]
Step 1: Confirm that your exact firmware supports TrollStore.
Step 2: Install TrollStore using the installation method appropriate for your device.
Step 3: Download the official Relaxin IPA or TIPA package.
Step 4: Open the downloaded package with TrollStore.
Step 5: Tap Install.
Step 6: Wait for Relaxin to appear on your Home Screen or App Library.
Step 7: Open Relaxin.
Step 8: Verify that your device and firmware are detected correctly.
Step 9: Tap the Jailbreak option and allow the exploit process to complete.
Step 10: Follow the on-screen instructions to initialize the RootHide environment and package manager.
TrollStore installations do not have the usual seven-day free Apple ID signing expiration associated with standard sideloading.
How to Install Relaxin With Sideloadly
Sideloadly is a good alternative when TrollStore is unavailable.
[DOWNLOAD RELAXIN IPA]
[DOWNLOAD SIDELOADLY]
Step 1: Download Relaxin 0.4.5 IPA to your Mac or Windows computer.
Step 2: Install and launch Sideloadly.
Step 3: Connect your iPhone or iPad to the computer using USB.
Step 4: Unlock the device and trust the computer if prompted.
Step 5: Drag the Relaxin IPA into Sideloadly.
Step 6: Select your connected device.
Step 7: Enter the Apple ID required for signing.
Step 8: Start the installation process.
Step 9: Complete any Developer Mode requirements shown by iOS.
Step 10: Open Relaxin after installation.
Apps signed using a free Apple ID generally need to be refreshed or re-signed periodically.
How to Install Relaxin With ESign
ESign allows you to sign and install IPA packages directly on an iPhone or iPad when an appropriate certificate is available.
[DOWNLOAD RELAXIN IPA]
[OPEN ESIGN]
Step 1: Download Relaxin 0.4.5 IPA to the Files app.
Step 2: Launch ESign.
Step 3: Import your signing certificate and provisioning information.
Step 4: Import the Relaxin IPA.
Step 5: Select Relaxin from the application list.
Step 6: Choose Sign.
Step 7: Wait for ESign to finish signing the package.
Step 8: Install the signed Relaxin application.
Step 9: Trust the certificate if your configuration requires it.
Step 10: Launch Relaxin.
Certificates used by ESign can expire or be revoked. If Relaxin suddenly stops opening, certificate status is one of the first things to check.
How to Install Relaxin With KSign
KSign provides another certificate-based method for installing IPA applications directly from an iPhone or iPad.
[DOWNLOAD RELAXIN IPA]
[OPEN KSIGN]
Step 1: Download the official Relaxin IPA.
Step 2: Launch KSign.
Step 3: Import a valid certificate and provisioning profile.
Step 4: Import Relaxin 0.4.5.
Step 5: Select the application.
Step 6: Start the signing process.
Step 7: Install the generated signed application.
Step 8: Complete any certificate trust requirements.
Step 9: Open Relaxin.
Step 10: Verify compatibility before starting the jailbreak.
As with ESign, KSign certificate availability does not affect whether the underlying Relaxin exploit supports your device.
How to Jailbreak With Relaxin 0.4.5
Before beginning, create a backup of important data and make sure the device has sufficient battery charge.
Close unnecessary applications.
Open Relaxin from the Home Screen.
Review the displayed compatibility information carefully.
If Relaxin reports that your firmware is unsupported, do not force the process using random modified versions.
Tap Jailbreak.
Relaxin will begin running the required exploit chain and preparing the RootHide environment.
The process may take several seconds and can involve a respring or userspace restart.
After a successful jailbreak, complete the bootstrap setup and open Sileo.
Relaxin Jailbreak Failed
Exploit-based jailbreaks do not necessarily succeed on every attempt.
If Relaxin closes unexpectedly, freezes or the device restarts, allow the phone to boot completely before trying again.
Make sure you are running Relaxin 0.4.5 or another build specifically intended for your firmware.
Avoid rapidly repeating the exploit after multiple failures.
A normal reboot can restore the device to a clean non-jailbroken state before another attempt.
Remove Jailbreak Option
Relaxin includes management features intended to help recover from problems with the installed jailbreak environment.
If the environment becomes unstable, an Advanced or Remove Jailbreak option may be available depending on the build.
Use the built-in removal function rather than manually deleting unfamiliar jailbreak files.
After removal, reboot the device and reinstall or reinitialize the jailbreak environment if necessary.
Relaxin Kernel Panic Fixes
Relaxin 0.4.5 specifically addresses stability problems that could result in kernel panics while launching processes. (Relaxin)
A kernel panic forces the device to restart because iOS detects a serious low-level error.
Occasional exploit failures remain possible with beta jailbreak software, but fixes targeting repeatable panic conditions can significantly improve day-to-day reliability.
If you continue experiencing frequent kernel panics, remove recently installed tweaks and test the jailbreak with a minimal configuration.
Relaxin Stuck on Jailbreak
First verify that your firmware is actually supported.
Force-close Relaxin and reopen it.
If the problem continues, reboot the device.
After restarting, try the jailbreak again before opening many other applications.
If you previously installed incompatible tweaks, use Relaxin’s recovery or jailbreak-removal functionality where available.
A tweak causing a userspace problem can sometimes appear to be an exploit failure.
Relaxin App Won’t Open
The cause often depends on your installation method.
For Sideloadly installations, your signing period may have expired.
Re-sign or refresh Relaxin.
For ESign or KSign installations, check whether the certificate has expired or been revoked.
For TrollStore installations, signing expiration should not normally be the issue on properly supported firmware.
If the app opens but the jailbreak fails, the problem is more likely related to compatibility or exploit reliability.
Relaxin vs Dopamine
Relaxin shares important architectural heritage with Dopamine.
The official Relaxin project identifies Dopamine and its RootHide fork as foundations for the project. (Relaxin)
Dopamine remains one of the most established modern rootless jailbreak platforms, while Relaxin initially focused heavily on extending a RootHide-oriented environment to newer iOS 17 hardware.
Recent Dopamine development also overlaps with some of the firmware targeted by Relaxin.
Users should compare current compatibility, stability and tweak support before choosing between them.
Relaxin vs RootHide Dopamine
RootHide Dopamine is a RootHide-oriented modification of the Dopamine jailbreak environment.
Relaxin also uses RootHide concepts but incorporates its own compatibility work, exploit integration and user interface.
Both target users who want a modern jailbreak environment with stronger isolation from ordinary applications than a traditional jailbreak configuration.
Neither solution guarantees complete jailbreak-detection bypass.
Relaxin vs NathanLR
NathanLR is another approach that has been used for tweak injection and partial jailbreak-style functionality on certain iOS 17 configurations.
Relaxin aims to provide a more complete semi-untethered RootHide jailbreak environment on its supported firmware.
Which one is appropriate depends on the device, firmware and desired functionality.
Do not switch between jailbreak environments without properly removing the existing setup first.
Relaxin vs TrollStore
Relaxin and TrollStore perform completely different jobs.
Relaxin is a jailbreak.
TrollStore is an application installation and persistent-signing solution for firmware affected by specific CoreTrust vulnerabilities.
On supported configurations, TrollStore can be used to install Relaxin.
Installing Relaxin through TrollStore does not mean TrollStore itself performs the jailbreak.
Does Relaxin Support iOS 16.5.1?
Yes. Relaxin 0.4.5 explicitly expanded compatibility to iOS and iPadOS 16.5.1. (Relaxin)
This is one of the most important changes introduced with version 0.4.5.
Does Relaxin Support iOS 16.6?
Yes.
iOS and iPadOS 16.6 are included in the expanded Relaxin 0.4.5 compatibility range. (Relaxin)
Does Relaxin Support iOS 16.6.1?
Yes.
Relaxin 0.4.5 added support for iOS and iPadOS 16.6.1 on compatible devices. (Relaxin)
Does Relaxin Support iOS 17?
Yes.
Relaxin was originally presented publicly as a jailbreak targeting iOS 17.0 through iOS 17.3.1 on supported modern devices. (Relaxin)
Later updates expanded the supported range downward to selected iOS 16 versions.
Does Relaxin Support iOS 17.3.1?
Yes.
iOS 17.3.1 remains the upper boundary of the currently published Relaxin compatibility window. (Relaxin)
Does Relaxin Support iOS 17.4?
Current Relaxin compatibility information does not list iOS 17.4 as supported.
Do not install an unofficial IPA promising iOS 17.4 support simply because it uses the Relaxin name.
Wait for confirmation from the project developers before treating a newer firmware as supported.
Can Relaxin Jailbreak iPhone 15 Pro Max?
The iPhone 15 Pro Max uses the A17 Pro processor, which falls within the modern hardware range targeted by Relaxin.
However, the installed firmware must also be inside the supported compatibility window.
An iPhone 15 Pro Max on a supported iOS 17 build is fundamentally different from the same device after updating beyond Relaxin’s supported firmware range.
Can Relaxin Jailbreak iPhone 11?
Current Relaxin 0.4.5 compatibility information includes hardware down to A12-class devices, placing the A13-based iPhone 11 family within the broader supported hardware range when running compatible firmware. (Relaxin)
Always verify the exact device and iOS build before beginning.
Does Relaxin Install Cydia?
Relaxin is designed for the modern jailbreak ecosystem rather than the traditional Cydia environment.
Its package-management setup uses Sileo.
Modern RootHide and rootless jailbreak tweaks are packaged differently from many legacy Cydia-era tweaks, so old packages should not automatically be installed.
Does Relaxin Support Old Jailbreak Tweaks?
Some older tweaks require conversion, patching or a newer RootHide-compatible build.
Do not assume that a tweak supporting an older rootful jailbreak will work unchanged.
Look for explicit RootHide or modern rootless compatibility information from the tweak developer.
Using an incompatible tweak can create respring loops, crashes or other instability.
Does Relaxin Bypass Banking App Detection?
RootHide is specifically designed to reduce the visibility of jailbreak components to normal applications.
However, no jailbreak can guarantee that every banking application will remain unaware of the modified environment.
Banks can update their detection logic at any time.
Treat RootHide as a compatibility and isolation technology rather than a guaranteed universal jailbreak-detection bypass.
Is Relaxin Untethered?
No.
Relaxin is semi-untethered.
The active jailbreak disappears after a full reboot, but the device can still boot normally.
Open Relaxin and jailbreak again to restore the RootHide environment.
Does Relaxin Need a Computer?
Not necessarily.
If you already have TrollStore or a working on-device signing environment such as ESign or KSign, Relaxin can be installed without a computer.
Sideloadly requires a Mac or Windows computer for installation and re-signing.
The availability of a computer-free installation method does not change Relaxin’s firmware compatibility.
Is Relaxin Safe?
Jailbreaking intentionally bypasses security protections that Apple built into iOS.
Relaxin’s modern RootHide architecture can reduce unnecessary system modifications, but it cannot eliminate the risks associated with executing jailbreak exploits and privileged third-party software.
Use only trusted packages, avoid unknown repositories and keep important data backed up.
Public-beta jailbreak software should be treated as experimental.
Back Up Before Installing Relaxin
Create an up-to-date backup before attempting the jailbreak.
Important photos, documents, authentication information and other irreplaceable data should never exist only on the device being modified.
An encrypted computer backup is particularly useful because it preserves more information than some basic backup methods.
Do not begin experimenting with jailbreak tweaks until you are confident your important data can be recovered.

Final Thoughts
Relaxin 0.4.5 is an important update for the project because it expands compatibility beyond the original iOS 17-focused releases and now covers iOS and iPadOS 16.5.1, 16.6 and 16.6.1 while continuing through iOS 17.3.1 on supported hardware. (Relaxin)
The stability fixes are equally important, particularly the corrections for problems that could cause kernel panics during process launches.
Relaxin’s combination of a semi-untethered design, RootHide architecture, Sileo support and compatibility with modern Apple hardware makes it an interesting alternative within the current jailbreak ecosystem.
For installation, TrollStore is convenient wherever it is already supported. Sideloadly provides a reliable computer-based route, while ESign and KSign are useful for users with suitable signing certificates.
Always confirm your exact iPhone or iPad model, processor and iOS version before installing Relaxin. Download releases through trusted project sources, back up your data before jailbreaking and avoid modified IPAs claiming unsupported firmware compatibility.
