Hacker Demos iOS 9.2.1 Jailbreak with Flying JB

Chinese Developer Min Zheng, better known by @SparkZheng has come with a refreshing news for jailbreakers, demonstrating iOS 9.2.1 jailbreak with a new app call “Flying JB”. He has recently published a YouTube video showing what he has invented by successfully Jailbreaking an iPhone 5c running iOS 9.2.1 with Flying JB that installs an unsigned Mobile Terminal app which gives facility to work any command as root.


Flying JB is based on “inpuTbag”, known as a 15 years old kernel HeapOverFlow vulnerability, which has almost patched in latest iOS 9.3.2. In that way this jailbreak will not work for iOS 9.3.2 and also for iOS 9.3 and iOS 9.3.1. So it is only good for some. Developer Zheng is not the only role behind this concept, in fact he has equally credited for Cererdlong and Eakerqiu for this successful Flying JB app which was extremely interesting to concern at a time jailbreak is missing from iOS 9.2 to above.

Who can use Flying JB?

This app only works on 32-bit devices which means, iPhone 5 or lower models running iOS 9.2.1 or lower. So iPhone 5, iPhone 5c and iPhone 4S running iOS 9.2.1 or lower can be use this jailbreak solution. In that way this is exciting only for some but it is a highly interesting invent in jailbreak chapters to refresh the crowd who were quiet with no-jailbreak up to now.

Is this the Jailbreak Solution you looked for?

Flying JB solution is not a GUI based tool, like most familiar Pangu or TaiG, in fact it would be a difficult process for average iOS users which would make Flying JB less interest. Opposed to popular Pangu jailbreak or TaiG, Flying JB works in a different way. In fact it is not for full jailbreak as it comes with a limited usage potential.


Flying JB is a smart concept but it lacks a sandbox escape, which means you are not able to get full functional jailbreak which makes Cydia install on your iOS. In fact Flying JB is not letting you come totally out of the Apple walls even with root access.

If you still think this is smart enough to try on your expensive gadget, visit Zheng’s “Github” for source codes to check the compatibility and follow instructions for a successful process. And it is important remember this is only capable of jailbreak devices on 32-bit running iOS 9.2.1 or lower.

After iOS 9.1 Pangu jailbreak in March, this is the next recent jailbreak tool we heard rather than proofs and rumors on a coming soon release. In that way this is extremely interesting even though it only caters a limited crowd. If you are willing to take the adventure, try Flying JB and remember to share your experience with us.
