Famous Chinese developer Min Zheng, commonly known as SparkZheng, has demonstrated a new iOS 9.2.1 jailbreak called ‘Flying JB’. The new YouTube video demonstration shows the Flying JB app begin to successfully jailbreak iOS 9.2.1 on a 32-bit iPhone 5c. Flying JB installs an unsigned mobile terminal app during the jailbreak procedure by giving you the permission to run any command like root. Flying JB iOS 9.2.1 will be a good option for worldwide jailbreakers.
Flying JB is not a GUI based tool. Zheng has revealed in a blog post that this Flying JB is based on inpuTbag. Even this Flying JB solution does not actually come with a graphical interface like the most famous jailbreak solutions, for an example Pangu. So jailbreak your iOS device will be extremely difficult with Flying JB tool.
‘Flying JB’ Jailbreak iOS 9.2.1 Compatibility
Apple has patched the vulnerability in iOS 9.3.2, meaning that the Flying JB jailbreak iOS 9.2.1 solution will not work on iOS devices running iOS 9.3.2 firmware. Flying JB’s developer Zheng has confirmed that the vulnerability was very powerful to exploit the iOS kernel before iOS 9.3.2.
Apple has added additional ‘entitlements’ of iOS 9.3 and iOS 9.3.1. So the Flying JB is much harder in iOS 9.3 and iOS 9.3.1. Please note that this Flying JB is only compatible for jailbreak apple’s 32-bit iOS devices. It means that the solution works only for iPhones and tablets that were built before apple moved across to its 64-bit builds. So you can use Flying JB on iPhone 5 or lower ( iPhone 5, iPhone 5c, iPhone 4s) running iOS 9.2.1.
How to work Flying JB jailbreak iOS 9.2.1 on iPhone 5/ 5c/ 4s
This video tutorial supports you to get an idea about Flying JB – iOS 9.2.1 jailbreak.
According to this video demonstration, it seems like a work in progress as the sandbox escape is not public yet. So we need to say you that Flying JB jailbreak is not a fully functional jailbreak like the majority of popular jailbreak solutions like Pangu, TaiG. Zheng has credited Cererdlong and Eakerqui for the jailbreak.
Flying JB will be the good news for jailbreakers. But it does not display anything about cydia. So you will need to stay some time for the real jailbreak solution if you expect to install cydia on your iOS device. But if you are an adventurous, then check out the source code on Github and follow its instructions to try jailbreak iOS 9.2.1.
