Untethered iOS 9 Jailbreak demoed on video by iH8sn0w

We’ve some good news for jailbreakers. iH8sn0w, a well-known and reputable hacker in the jailbreak community, has demonstrated an iOS 9 untethered jailbreak running on his iPhone 5.

iH8sn0w is running the just-released iOS 9 GM seed on his iPhone, as proven by the 13a340 build number seen in the About section of the Settings app. The jailbreak is an untethered jailbreak, so you won’t lose the jailbreak when you reboot your device.

Here’s a video of it in action :

He has provided the following details about the security features in iOS 9:

Poking into iOS 9 is fun. A little annoyed at some new things. But very surprised at how similar it is to iOS 8 internally.

Worth noting, iOS 9+ arm64 iDevices now enforce a checksum on __TEXT/DATA.const regions of the kernel through the use of TrustZone. Modifying said sections will cause the device to panic (either at kernel or EL3 will force a reboot if the kernel refused to gracefully panic). Essentially, it’s KPP (Kernel Patch Protection). You can race it though if you want to play with things. Just be quick! ;P

Also, there should technically now be two additional partitions (baseband_data [s1s3] and logs [s1s4]) but didn’t really bother with those as they weren’t critical.

The video does not tell us when a jailbreak for iOS 9 will be released for public, although it certainly shows that a jailbreak is indeed possible. This is a big relief for the jailbreak community who were afraid Apple might get its way this time around and block the jailbreak for a long time, if not forever.

Few days back Pangu team had confirmed that Apple had patched two exploits used in the iOS 8.4.1 jailbreak, so we thought that it will make it even more difficult to jailbreak iOS 9. So it is quite impressive that he has managed to jailbreak iOS 9.

While several jailbreak teams have been working on it, it is the first time a jailbreak for iOS 9 has been demoed.

Apple should ideally release iOS 9 with the same build number as iOS 9 Golden Master, so it will be possible to jailbreak the public release as well. It remains to be seen if iH8sn0w will release a jailbreak for iOS 9. But since iOS 9 can be jailbroken, it is also possible that Pangu and TaiG team can discover the exploits, and release a jailbreak for iOS 9.

It would still be prudent for jailbreakers to avoid upgrading to iOS 9 when it is released on September 16, and wait for the jailbreak tool to be released.

As always, we’ll let you know as soon as we get any further details about the iOS 8.4.1 jailbreak.
