iOS 7.1.1 Jailbreak Untethered for iPhone 5S by Winocm, i0n1c and GTISC

iOS 7.1.1 jailbreak untethered for iPhone 5S / 5c / 4S / 5 / 4 is not available to public yet though several hackers managed to create programs that can jailbreak this firmware version. Hackers have added videos of their jailbroken smartphones to YouTube and mentioned the happy news via Twitter accounts. Once Winocm and i0n1c have proved that iPhone 5S jailbreak for iOS 7.1.1 is possible, the exploit was developed by two followers, Tielei Wang and Yeongjin Jang from GTISC.

The video that lasts for about 4 minutes displays the jailbreak for iOS 7.1.1 iPhone 5S in action. Mr. Jang has also shown how he installs a program distantly on his smartphone. The unsigned application works on a jailbroken device.

Unlike jailbreak for iOS 7.1.1 untethered from i0n1c, the exploit found by GTISC hackers is tethered. This is still the jailbreak and even though it requires to use a recovery program after each reboot it still can support jailbroken tweaks and apps.

According to Jang, he used the sandbox bypass, root and codesign bypass to jailbreak his iPhone 5S. It is not know whether this hacker used the similar jailbreaking method as i0n1c and winocm, as he gives no explanations of the exact process
