Prolific jailbreak-developer team 'Pangu' recently rolled out the highly-anticipated semi-untethered jailbreak for iOS 9.2 through iOS 9.3.3, which requires you to run the jailbreak app every time the device is rebooted or restarted. Although the installed jailbreak tweaks are not removed, they won't be functional until you re-jailbreak your device after the reboot.
Note: A re-jailbreak is not necessary if you respring or wake your iPhone or iPad from sleep. But, it is a needed if your device reboots after installing some app.
Here is how to re-jailbreak your iOS device with PP aka Pangu jailbreak installed after the first reboot:
Step 1: Launch the Pangu aka PP Jailbreak app from the device's Home screen.
Step 2: When a prompt asks you to allow notifications from the app, just hit the Ok button.
Step 3: Hit the circle button at the center of the screen to lock your device.
Step 4: You should soon see a notification on the PP jailbreak tool along with a "Storage Almost Full" message. Just ignore the warning and leave your device unlocked.
Step 5: Wait until the re-jailbreak process completes and your device will re-spring. Cydia should now become accessible along with all the tweaks installed.
Those who are yet to install the Pangu jailbreak for iOS 9.2 through iOS 9.3.3 can follow our step-by-step guide posted here.
