What is Taurine Jailbreak?

Taurine is an open-source jailbreak with support for iOS 14 up to iOS 14.3. It installs Sileo, a Cydia alternative, that allows you to download tweaks and apps on your jailbroken devices from popular repositories. The jailbreak is using libhooker library for the best experience.

This is a semi-untethered jailbreak. It means that after every restart of your iPhone or iPad the jailbreak will be removed. To change the state to jailbroken you need to re-jailbreak the device again with the app. When Taurine jailbreak will not open you will also need to re-install it.

After opening the Taurine jailbreak you will see a few options to choose from. There is an option to enable running tweaks, change app theme, disable iOS updates, and set nonce generator. Turning off automatic iOS updates is crucial for not losing the possibility to jailbreak.

What's more, it features a useful Restore RootFS function. When this option is toggled on and you will tap on re-jailbreak Taurine will restore the device to the state before jailbreak. Use this switch to remove all installed apps and tweaks from your jailbroken device.

Be aware, that Restore RootFS doesn't remove all leftovers after Taurine Jailbreak. To restore your iDevice to a clean system use Succession app. Unlike iTunes, this tool will not upgrade the device during the process and it can restore the actual installed not signed iOS firmware.

Another useful tool packed with the Taurine Jailbreak is the "Set nonce generator". This option allows you potentially to downgrade or upgrade your device to a not signed iOS firmware. Apart from nonce, you need to use futurerestore application and saved blobs for your device.

Nonce is a signing method that randomizes Apple's cryptographic signature hash blobs and is used with the baseband signing ticket, the APTicket, and SEP (Secure Enclave). Every time you restore the device, a random string of letters and numbers is generated.

Using Taurine Jailbreak you can set manually nonce of the device. If the nonce and APTicket match, this allows restoring even no longer signed IPSW system files.

Like all other jailbreaks released by @CoolStar also Taurin installs Sileo as the default package manager for iOS 14. The tweak manager was written in Swift and is focused on speed and usability. It was designed to provide a real Cydia alternative for jailbroken devices.

Taurine Jailbreak supports all releases of iOS 14, iOS 14.2, and iOS 14.3. If you are running a different iOS 14 release such as iOS 14.4, iOS 14.4.1, iOS 14.4.2, iOS 14.5, iOS 14.5.1, iOS 14.6, iOS 14.7, iOS 14.7.1, or iOS 14.8 try different jailbreak tools such as unc0ver or checkra1n.

Developers behind Tautrine promised that jailbreak could receive iOS 14.6 - 14.8 support in the future, but they never delivered. On the other hand, Taurine is still under active maintenance. The successor of Odyssey jailbreak for iOS and iPadOS 13.0 - 13.7 will receive an update.

Taurine15 for iOS 15

Taurine15 will be named Cheyote and it will initially support iOS 15.0 and iOS 15.1.1 running on iPhones and iPads. To be precise the jailbreak supports iOS 15.0 - iOS 15.1.1 running on A8 - A11 devices (new exploits should be easily implemented),and iOS 15.0 - iOS 15.1.1 only on A12+.

This means that iPhone 12, iPhone 11, iPhone SE, iPhone XS Max, and iPhone XR are supported only on iOS 15.0 - iOS 15.1.1. If you are using a newer version of the iOS firmware you will be not able to jailbreak using this tool. There are no other active jailbreaks developed for iOS 15.

@CoolStar, the main developer behind Taurine Jailbreak for iOS 15 announced that this will be her last jailbreak released for iOS. She was in the jailbreak community for years creating Sileo APT and various jailbreaks such as Electra, Chimera, Oddysay, and Taurine.

Cheyote Jailbreak will add support for iOS 15 and should be released soon to the public. Support for iOS 15.2 up to iOS 15.4.1 will be looked into afterward but is not guaranteed. This will be a rootless jailbreak which means that not all tweaks will work out of the box and developers will need to update them to support this jailbreak.

iOS 15.4.1 is not being signed anymore by normal methods but if you are below 15.4.1 you can still upgrade to using DelayedOTA until August 13, 2022. If you running iOS 15.0 - 15.1.1 it's recommended to stay on those versions.

On-device IPA signing

To prevent the Taurine Jailbreak from getting revoked by Apple or after the free certificate 7-day limit it is a good practice to use a jailbreak tool like ReProvision Reborn. With this app, you can sign Taurine Jailbreak with a free certificate based on your Apple ID without a computer.

Sign Taurine Jailbreak IPA on-device with ReProvision

How to jailbreak iOS 14

Taurine App is a stable tool to jailbreak iOS 14 and install Sileo to allow you to download Cydia tweaks on your device. After you sideload the Taurine IPA onto your iPhone or iPad you are just a few steps from jailbreaking. This is how to do it.

Be aware, that every time you reboot the device the jailbreak will stop working. Open the app again and tap on "Jailbreak". If the app will expire, install it again with the preferred method.

Step 1. Install Taurine Jailbreak on iOS 14.

Step 2. Open the Taurine app from the Home Screen.

Step 2. Once launched, tap on the "Jailbreak" button.

Step 3. Wait for the tool to exploit the system and respring.

Step 4. Launch Sileo from the Home Screen to install tweaks.

Remove iOS 14 jailbreak

To completely remove Taurine Jailbreak open the app and enable the Restore RootFS option. Re-jailbreak the device and Taurine will restore the backup before jailbroken state. There is no need to manually remove installed tweaks and apps when using this function.

Taurine Jailbreak Untether

Linus Henze, the dev behind Fugu14 Jailbreak and the untether for iOS 14.3 up to iOS 14.5.1, discovered a new bug where CoreTrust will allow to use of any root certificate to permanently sign any IPA file for all jailbroken devices running iOS 14 and iOS 15. Using this method you can install the Taurine app on your iDevice so it will not be revoked after 7-days.

This makes basically the Taurine Jailbreak an untethered jailbreak that allows you to re-jailbreak the system at any point once installed. No need to re-sign the app with a computer. What's more, the jailbreak will work after the device will shut down or gets restarted.

To create an untethered version of the Taurine Jailbreak app for iOS 14 use the IPA Permasigner script. With a few simple steps, it will permanently sign the Taurine.IPA to allow the app to run even without revokes. Below you can find the permanently signed Taurine app.

  1. Install Taurine app for iOS 14 with a preferred method.
  2. Jailbreak the iOS 14 system with the installed app.
  3. Install the Taurine Untether DEB package with Filza.
  4. Restart the device to check if the app works.

Switch from unc0ver to Taurine

Taurine Jailbreak can't be installed directly on an already jailbroken device with unc0ver installed. To switch from unc0ver to Taurine you need to use the Restore RootFS feature (available in unc0ver's settings) that will bring your device to stock iOS but a better approach would be to create a new snapshot with a jailbreak app like SnapBack.

A new snapshot will allow you to switch, when needed, between unc0ver and Taurine jailbreak with a simple tap. It will save all settings and tweaks installed for each jailbreak separately with the option to recover each snapshot or return the system to the RootFS state.

  1. Install SnapBack from the official repository on your device.
  2. Open the newly installed app from the Home Screen.
  3. Tap on the plus button available in the right corner.
  4. Enter a name for your snapshot eg. "unc0ver backup".
  5. SnapBack will create now an unc0ver APFS snapshot.
  6. Tap on the "orig-fs" snapshot and confirm to "Jump to Snapshot".
  7. Install Taurine Jailbreak with your favorite tool on iOS 14 - iOS 14.3.
  8. Jailbreak your device with the Taurine app.

Now you managed to successfully switch from unc0ver to Taurine jailbreak on your iOS 14. Create a new snapshot with SnapBack for a clean Taurine backup that will allow you to restore it when needed. Install all tweaks and apps on your jailbroken device and enjoy your new setup.
