Saurik update Cydia Substrate and comment of Pangu issue

Saurik recently pushed a small Cydia Substrate update to fix issues with devices running versions of iOS prior to iOS 5. The update, which comes in at version 0.9.6011, was pushed to fix a problem that arose during the 0.9.6xxx series of Cydia Substrate updates.

While this update is small, and probably only affects a handful of jailbreakers, the more important issue of jailbreak stability was mentioned by Saurik recently via Twitter. As you’re likely aware of, some have been experiencing issues with non-recoverable boot loops after restarting their jailbroken devices running iOS 9…

I rebooted an iPhone 6S running iOS 9.0.2 jailbroken with Pangu9 almost 1100 times today: 85% of boots worked, 0.4% took 10 minutes to fail.

As we've told you before, some users faced a problem called 'Boot loop of death' when using pangu jailbreak for iOS 9-iOS 9.0.2.

This issue has been unofficially labeled the Boot Loop of Death or BLoD. It happens upon a force reboot that never progresses beyond the Apple menu, even after 10 minutes of waiting. My best advice is to force reboot your iPhone immediately after jailbreaking. If, after at least a 10 minute wait, your iPhone stays stuck at the Apple logo, then it’s probably best to restore and try again. If you’re able to successfully force reboot, then you should be good.
