How to Re-Sign a Semi-Untethered Jailbreak

When you install a semi-untethered jailbreak using Cydia Impactor and a free Apple ID, the certificate of the jailbreak app lasts for 7 days only, after which the app will start to crash. To fix this problem, you'll have to re-sign the jailbreak app via Cydia Impactor again. Here's how:

Step 1: Remove the jailbreak app from your device.

Step 2: Connect your jailbroken iPhone or iPad to your computer and open Cydia Impactor.

Step 3: Drag and drop the jailbreak IPA file onto Cydia Impactor.

Step 4: Enter your Apple ID and password as prompted. This information will be sent to Apple to generate a signing certificate for the IPA file.

Step 5: Cydia Impactor will begin reinstalling the jailbreak app onto your device. Once done, the app's icon will appear on your device's Home screen.

Step 6: Before launching the app, go to Settings > General > Profiles & Device Management and tap on the profile with your Apple ID.

Step 7: Press the"Trust" button, then go to the Home screen and you should be able to open the jailbreak app and perform a jailbreak if required.

You have to repeat this process every 7 days to re-sign the jailbreak app and avoid crash issues. After the 7 days period, you can continue using your jailbreak tweaks and Cydia as normal unless your device reboots and the jailbreak gets disabled. At this point, you've have to re-sign the jailbreak app.
