Installing Odyssey

Odyssey is a semi-untethered jailbreak, meaning it requires a app to re-apply the exploit after a reboot. Click the link to learn more.

If you are already jailbroken with unc0ver, make sure to properly remove it before proceeding.

Due to how semi-untethered jailbreaks work, the app will need to be re-signed once every 7 days.

We will use AltStore to install the Odyssey jailbreak application to your iOS device for use in the next step.


Odyssey is currently signed at for easy installation without a computer.
