Not long after Pangu released a jailbreak for iOS 9.3.3, famed developers iMokhles and Ahmed ALNeaimy created a convenient browser-based version of Pangu’s jailbreak that enabled users to install the jailbreak app directly from their device without the need to connect to a computer.
Unfortunately, this method no longer works for now as Apple has revoked the certificate used to install the PP Jailbreak app on your device. If you attempt to jailbreak with the Safari-based tool, you’ll be greeted with an error that says “‘PPJailbreak’ could not be installed at this time.”
The jailbreak app installation requires the corresponding certificate to be installed on your device before proceeding with the process. Since Apple has stopped signing the certificate, users will be prevented from installing the app onto their devices, hence the reason for seeing the error above.
A temporary workaround is to sign the PP jailbreak app with a different Apple Developer account but that isn’t going to last long as Apple will most definitely take an action against it as well.
This move by Apple isn’t surprising at all considering the stance that it has against jailbreaking. Misuse of the enterprise certificate system is against the policies of Apple Developer Program, no matter how much jailbreaking is favored by some of us.
Those of you who want to jailbreak your iOS 9.3.3 device can still use the original method that requires a Windows-based tool to be downloaded to install the PP jailbreak app onto your device.
If you have already jailbroken your device using the Safari-based tool then you’re good for now unless the certificate expires. In case that happens or you lose the jailbreak app for some other reasons, you’ll have to use the 25PP Windows-based tool to install it again onto your device.
