    • If the button says Jailbreak, go back and check to see if Restore RootFS is the only option enabled
  8. When prompted about restoring, tap OK
    • This may take some time
    • If it fails, try again from the beginning
  9. When finished, tap OK again and your device will restart
  10. Open the Settings application
  11. Go to General -> Software Update
  12. Download the software update but do not install it
  13. Go back to General
  14. Once downloaded, go to iX Storage like before
    • This could be iPhone Storage, iPad Storage or iPod Storage
  15. Scroll to the System Update downloaded and tap on it
  16. Tap Delete
  17. Scroll to the unc0ver application and tap on it
  18. Tap Delete
  19. Install unc0ver again like before but don’t run it yet

If this doesn’t work, ask on the r/Jailbreak Discord Server for support.
