If your device is jailbroken you should keep track of when iOS 10 jailbreak certificate will expire. As you may know both the Yalu jailbreak for iOS 10 devices and the Pangu jailbreak for iOS 9 rely on certificates that have expiration dates. You have to re-sign the jailbreak with Cydia Impactor past the expiration date to keep your jailbroken state.
No matter what kind of certificate you have, whether it’s a regular 7-day certificate or a 1-year developer certificate, it will expire anyway, and a new jailbreak app called CertRemainTime by developer lululombard can help you keep track of it. Read how to install CertRemainTime app on your device.
How To Keep Track Of When iOS 10 Yalu Jailbreak Certificate Will Expire
To get started head to Cydia’s Bigboss repository and download CertRemainTime app on your jailbroken device. The app works on all devices jailbroken with the Yalu jailbreak for iOS 10. Keep in mind that the app only works if you’ve jailbroken with Cydia Impactor. If you have jailbroken with any other way, such as via a web browser, the app is not guaranteed to work.
CertRemainTime is a simple app that gets added to your Home screen that’s always consciously aware of how long your Yalu jailbreak has before it needs to be re-signed. The app is really easy in use as it keeps track of when iOS 10 jailbreak certificate will expire by showing the date on the screen and that's it. The
example is shown below.
The app detects your jailbreak certificate info automatically and reports the date and time that it’s set to expire in the app, without any configuration at all.
CertRemainTime is not only a great app for the forgetful person, but it is recommended to have a utility that reminds you when it’s time to keep a computer nearby. After all, if you reboot your jailbroken device when the certificate is expired, and you don’t have a computer nearby, you’ll end up jailbreak-less until you get back to your PC again.
