Earlier this month when we reported about Pod2g working on an untethered iOS 7.1.1 jailbreak, we also mentioned that currently there’s no jailbreak available for iOS 7.1 or iOS 7.1.1 firmware. It’s because Apple patched the exploits used in Evasi0n7 jailbreak with the release of iOS 7.1. However, that didn’t keep iOS hackers from further digging deep into the iOS and find loopholes to exploit them to achieve root access. Things seems to be going good for the iOS 7.1.1 jailbreak so far, as the i0nic has successfully jailbreak iPhone 5c running iOS 7.1.1.
Stefan Esser – also known as i0nic, who is a security researcher, has successfully jailbroken iOS 7.1.1 on his iPhone 5c, and to prove that, he tweeted a photo of his iPhone 5c jailbroken and running iOS 7.1.1 firmware.
The photo shows an iPhone 5c running Cydia 1.1.9 running iOS 7.1.1 firmware. Although it’s easy to fake such photos, if you’ve been jailbreaking your device for very long, you’re probably well aware of i0nic’s history. He has previously released jailbreaks, but then left the jailbreak community and hasn’t looked back other than sharing his thoughts about the evad3rs and other jailbreak related stuff.
Here’s the photo he posted on his twitter handle, along with some tweets related to the vulnerability he used to achieve iOS 7.1.1 jailbreak.
“That iOS 7.1.1 jailbreak is not based on a long vulnerability chain. It uses a single beautiful kernel bug that goes from mobile to kernel.”
It’s unclear if i0nic will even release this jailbreak to general public, because he’s known for tweeting teasers only. Evad3rs and winocm has also been working on the jailbreak. A public release after the availability of iOS 8 is very likely given that the available exploits work on it.
It’s not the first time we’re seeing such teasers, before this we have seen iPhone 4S 7.1 jailbreak and iOS 7.1 jailbreak on iPhone 4.
The last public untethered jailbreak was evasi0n7, and it was released by evad3rs and it supporter iOS 7.0 – 7.0.6. Unfortunately, the vulnerabilities used in evasi0n were patched in iOS 7.1.
