Pangu 8.0-8.1.x Untether 0.2 update available on Cydia (again) along with Cydia Substrate 0.9.5015 update

Pangu 8.0-8.1.x Untether 0.2 update

Few hours back, Pangu Team had released the Pangu 8.0-8.1.x Untether jailbreak update to fix the Cydia Substrate loading issue after a reboot, iMessage picture sending issue and Safari crashes. 

The update was initially available via both the Pangu app (that was installed at the time of the jailbreak) and Cydia. However, saurik removed the package from Cydia after users reported issues booting their devices after installing the untether update.

It looks like the Pangu 8.0-8.1.x Untether jailbreak is available again on Cydia. Saurik had also released an update for the Cydia Substrate (previously called Mobile Substrate) to fix the Cydia loading issue after a reboot, alongside the untether update.

Here’s the release notes of Pangu 8.0-8.1.x Untether jailbreak:

Version 0.2 of this package fixes an issue that caused Cydia Substrate to not fully load into many processes immediately after rebooting. After installing this untether update, you no longer need to respring after rebooting to make Cydia Substrate work.

This update also solves the Safari and iMessage bugs that some users reported. (For developers: the issue with RWX pages was also fixed.)

As this update makes Substrate work more consistently, installing this update exposed bugs in Substrate 0.9.5013 for many users. It is important to also use the latest versions of Substrate (at least version 0.9.5014) with this new untether.

And here’s the release notes of Cydia Substrate 0.9.5014 and 0.9.5015 update:

Cydia Substrate 0.9.5014 fixes a few bugs reported on iOS 8 with 0.9.5013, including “apps do not install”, “iTunes does not sync”, and “icons are gone”.

This issue sometimes led to devices being unable to boot without disabling Substrate (holding down volume up).

(and 0.9.5015 fixes a bug in 0.9.5014 where some processes, including OpenSSH, would no longer start.)

saurik also goes on to clarify that untether update along the Cydia Substrate update should fix the issue that caused Substrate to not fully load into many processes immediately after rebooting.

If you’ve updated the Pangu 8.0-8.1 untether to version 0.2, you no longer need to respring after rebooting; this untether update fixes an issue that caused Substrate to not fully load into many processes immediately after rebooting. This untether update also means that disabling Substrate while booting (by holding the volume up button) should work consistently now.


Pangu Team has also advised users to disable passcode and Touch ID before installing the update as it requires a reboot, and could issues while rebooting.

Updating this package requires a reboot; please note that rebooting can surface problems unrelated to the untether or Cydia Substrate. If you’ve set a passcode/TouchID, rebooting may cause your device to freeze: please disable passcodes/TouchID until further notice (sorry :/). Having incompatible tweaks installed can also cause problems upon rebooting.

So you may want to first disable passcode/Touch ID, followed by installing the update for the Cydia Substrate, and then the Pangu 8.0-8.1.x Untether 0.2 update from Cydia. You can check out the video tutorial below if you need help on installing the update.

It is also important to note that Pangu Team have released the jailbreak primarily for developers so Cydia developers can update their tweaks and apps for iOS 8 – iOS 8.1, so one shouldn’t expect things to work flawlessly. It may still be prudent to hold off jailbreaking your device until issues at the time of reboot when you’ve passcode/Touch ID enabled are resolved.

The Pangu Team is working on a fix to resolve the booting issue that is affecting users that have passcode enabled, and also working with saurik to include Cydia in the Pangu jailbreak so it is pre-installed when users jailbreak your device on iOS 8 – iOS 8.1.
