The connected Apple Watch may re-sync after jailbreak. It will take around a minute or two and it won't touch your data

You can switch back to the checkra1n jailbreak while preserving your jailbreak apps and tweaks but you will need to manually install Cydia Substrate from Cydia after switching back

Your jailbreak apps and tweaks will be preserved when switching from the checkra1n jailbreak for A8-A11

There is no particular reason to switch to the unc0ver jailbreak if you are already running the checkra1n jailbreak (Other than the convenience of being able to re-jailbreak your device without a computer)

@Pwn20wnd's substitute bootstrap tooling is used on A8-A11 devices running iOS 13.0-13.3 for battery saving features, improved performance and compatibility reasons

You must reboot in order to install this update if you are already jailbroken

Below you can find official download links for the beta IPSW. This is the latest signed iOS version compatible with unc0ver. Running beta iOS software is not recommended if not necessary.

unc0ver is a jail​break, which means that you can have the freedom to do whatever you would like to do to your iOS device. Allowing you to change what you want and operate within your purview, unc0ver unlocks the true power of your iDevice.

Unc0ver has been extensively tested to ensure it's a seamless experience on all devices. Unc0ver works on all devices on iOS versions between 11.0 and 13.5.5 Beta 1. Below you can find a list of all devices that have been specifically tested.

Important Information

unc0ver is designed to be stable and enable freedom from the moment you jail​break your device. Built-in runtime policy softener allows running code without Apple's notarization and pervasive restrictions. Proper runtime modifications to iOS kernel modify security features as necessary and result in:

No Extra Security Vulnerabilities

unc0ver preserves security layers designed to protect your personal information and your iOS device by adjusting them as necessary instead of removing them. With this security adjusted on your iOS device, you can run your favorite jail​break apps and tweaks while still being protected from attackers.

Stability & Battery Life

unc0ver is tirelessly developed and rigorously tested with software stability and battery life in mind. If you're experiencing issues with stability or battery life, we recommend searching your device for faulty tweaks.

Reconciliation of Services

Services such as iCloud, iMessage, FaceTime, Apple Pay, Visual Voicemail, Weather, and Stocks, have been reconciled and still work on the device.

Future Software Updates

The ability to apply future updates is retained. Modifications to iOS kernel are done in memory. This results in the jailbroken iPhone, iPad, or iPod touch staying operable when a future Apple-supplied iOS update is installed.

iOS Updates

unc0ver Team strongly cautions against installing any iOS software update that breaks unc0ver as you can't re-jail​break on versions of iOS that are not supported by unc0ver at that time.

Jail​break Legality

It is also important to note that iOS jail​breaking is exempt and legal under DMCA. Any installed jail​break software can be uninstalled by re-jail​breaking with the restore rootfs option to take Apple's service for an iPhone, iPad, or iPod touch that was previously jailbroken.
