Chinese hackers from the Pangu team were in a hurry to release a utility for untethered jailbreak of iOS 8, and therefore the first version of Pangu8 was not very successful.
Recall that the creators themselves reported that the first build of the utility is intended more for tweak developers, but not for ordinary jailbreakers. Errors and bugs were observed on jailbroken devices, the jailbreak did not include an alternative Cydia app store – it had to be installed manually using OpenSSH.
However, hackers gradually brought their creation to mind – when jailbreaking, Cydia began to be installed automatically, the utility received in addition to the Chinese English interface, changes were made to correct the detected errors. And now that Pangu8 1.2.1 has already been released, Cydia creator Jay Freeman, aka Saurik, admitted that the jailbreak has become stable:
If you’ve been postponing jailbreaking your device while waiting for the jailbreak to become stable, then this moment has come. Cydia developers can now specify support for iOS 8 in their products. The stability of the jailbreak allows it.
