Installing unc0ver

For support in English, ask for help on the r/Jailbreak Discord Server.

unc0ver is a semi-untethered jailbreak, meaning it requires an app to re-apply the exploit after a reboot.

The tool is capable of jailbreaking nearly every iOS device on firmware version 11.0 up to 14.8 (excluding iOS 12.5.6/12.5.7), however, for our purposes, it will be used to jailbreak devices in which no easier option is available.

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

We will use Sideloadly to install the unc0ver jailbreak application to your iOS device for use in the next step.


If you are using a device running iOS 14.0 to 14.3 or 14.6 to 14.8, it is highly recommended to follow Installing unc0ver (TrollStore) instead.


If you are looking for the guide on how to use unc0ver on A12 or newer devices on firmware versions 14.4 to 14.5.1, continue to Installing unc0ver (Fugu14)


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


unc0ver on firmware versions 14.6 to 14.8 only supports A12 and A13 iPhones.


unc0ver is currently signed at for easy installation without a computer.

Installing the application

  1. Open Sideloadly
  2. Plug your iOS device into your computer
    • Make sure your computer is trusted and allowed to view the contents of your device
  3. Drag and drop the unc0ver .ipa file into Sideloadly
  4. Enter in your Apple ID
  5. Enter in your password
    • Sideloadly must make a request to its servers in order to work with free developer accounts. If you are not OK with this, you may use an alternate Apple ID.

The app will now install to your iOS device.

Trusting the application

  1. Go to Settings -> General -> Device Management -> <Your Apple ID>
    • Depending on your usage, Device Management may be labeled Profiles and Device Management
  2. Tap Trust "<Your Apple ID>"

The unc0ver application can now be opened from home screen.

Running unc0ver

  1. Reboot your phone
    • This is not necessary but recommended
  2. Open the unc0ver application from your home screen immediately afterwards
    • If unc0ver warns you that the app has been tampered with, reinstall unc0ver via Sideloadly
  3. Open the settings menu and disable the Disable Auto Updates toggle
    • unc0ver disables Over-The-Air updates by default, however it's recommended to toggle this as it can cause issues when updating manually if not disabled
  4. Tap "Done"
  5. Tap "Jailbreak"
  6. Reboot your phone when prompted
  7. Open the unc0ver application from your home screen immediately after rebooting
  8. Tap "Jailbreak"


If the app or your device crashes/restarts unexpectedly and the jailbreak isn't installed, simply try rebooting and running the exploit again until it does work.


If you receive the error rootFS already mounted, delete the OTA update, read the Troubleshooting page

You should now be jailbroken with Cydia installed on your home screen. You can use Cydia to install tweaks, themes and more.
