Then there must be users who find out why the Cydia flashback is turned on for two reasons.

  1. When the device is rebooted, open the uncover jailbreak tool and click “Jailbreak” to activate the jailbreak.
  2. If you are not in a jailbreak environment, you should also open the uncover jailbreak tool and click “Jailbreak” to activate jailbreak.

Since this is an app that has not been reviewed by AppStore through its Apple ID free developer account, it will cause the “unc0ver” jailbreak app to be re-signed by the computer every seven days. Otherwise, the next time you reboot, it will cause the unc0ver App flashback to fail to open normally to activate the jailbreak environment. You only need to follow steps 2 through 8 to successfully open the Cydia APP and activate the jailbreak environment.

But if you don’t shut down after 7 days, it will not cause the impact of jailbreak environment. Normally it will not affect it. You can also use it after 7 days without restarting. When you suddenly want to reboot, you can re-do it through the computer. Install unc0ver jailbreak app once .

However, for the seven-day re-signing problem, you don’t need to feel too much trouble. In the past, the father of Cydia has launched the Cydia Extender tool to solve this problem. You can reinstall the jailbreak app directly through iOS. You don’t need to re-sign through the computer. Please see the teaching below

 

Upgrade Jailbreak App Tool Four Steps

  1. Remove the old jailbreak app first (just like deleting the app)
  2. iOS device reboot
  3. Install a new version of the app using Cydia Impactor on your computer
  4. Activate jailbreak, update completed

Please do not install it arbitrarily or support the iOS 12 plugin to avoid conflicts. It is recommended to support it through the ” iOS 12 Support List Query “.

 

Note that the current SHSH authentication has been closed, you can no longer use iTunes to repaint or reply to iOS 12.0~12.1.3 or previous version, you can only use the jailbreak tool, switch to “Settings” and “Restore RootFS (rec0ver)”, You can reply to the snapshot environment that was originally without jailbreak.
