CydiaFree is a powerful jailbreak tool that jailbreaks iDevices partially and installs Cydia on them. And the people who have a compatible device have already upgraded to it and downloaded Cydia on it.
Apple recently released iOS 15.2 for the iDevice users.
To fix this, all you need to do is reinstall the Pangu app using the instructions you just followed.The upcoming curiosity among Apple device users is the Cydia Download iOS 15.2.1. This is because the certificate for it will have expired.
If you do not have a paid Apple developer account, the Pangu app will start to crash one week after being installed.Once your device resprings, your jailbreak functionality will be restored!.To fix this all you need to do is open the Pangu app, tap ‘Start’, lock your device and wait 6 second for your device to respring (do not press anything on the device in those 6 seconds) As this is a Semi-Tethered jailbreak, after you reboot your device all jailbreak features will be disabled.Cydia should now be on your home screen and working! Once Cydia is installed your device will respring.Do NOT do anything else with the device while this is happening. The Pangu app should now be installing Cydia. Once you do this you need to lock your device, wait for a notification to appear on your lock screen and then unlock it. Once the Pangu app is installed, open Settings and navigate to General>Profiles & Device Management and find the Pangu app profile (should be your Apple ID).The Pangu app should now be installed on your device. Once you have entered your Apple ID and password, click ‘OK’.This is used only to create a certificate for the Pangu app to be installed and will not be visible to anything other than Apple’s servers. You will be asked to enter your Apple ID.Find the Pangu app IPA file you downloaded earlier and drag it into the Cydia Impactor tool.Select your device in the drop down menu. Once it opens, make sure your iOS device is plugged into your computer, and that your passcode, Touch ID lock and Find my iPhone is turned off during the jailbreak process.Then download Cydia Impactor (a program made by saurik) for your operating system from the links above. Download the English Pangu jailbreak app from the link above and save it somewhere.
However all newer iPhones, iPod touches and iPads will work with this new tool. This new jailbreak only works with 64-bit devices, meaning it will not work with the iPhone 5 or 5c unfortunately. The new jailbreak tool can be downloaded from Pangu’s official website and is compatible with iOS 9.2, 9.2.1, 9.3, 9.3.1, 9.3.2 and 9.3.3.
