iOS security researcher Stefan Esser aka known as i0n1c jailbreaker, recently showcased an untethered iOS 7.1.1 jailbreak on the iPhone 5c, followed by another untether by Winocm, also demoed how iPhone 4 jailbroken on 7.1.1. Now, yet another Chinese hacker named ‘Yeongin Jang has apparently demonstrated a video showcasing the process of installing an unsigned app on a jailbroken iPhone 5s running iOS 7.1.1. However, when you watch the video, it appears that this is a tethered jailbreak!
Hot trends are popping up, but iOS 7.1 brought an end to the versatile Evasi0n7 jailbreak, which let anyone using iOS 7 to iOS 7.0.6 run third-party or jailbreak apps on their iOS devices. Unfortunately, these are the three proofs of an iOS 7.1.1 jailbreak posted online.
This Jang’s four-minute clip of an iOS 7.1.1 jailbreak will partially be encouraging for those stuck on iOS 7.1 or newer and looking for the jailbreak to arrive. Although, its unclear whether this jailbreaking method uses the same technology to that of i0n1c’s single, kernel exploit. Yeongjin now joining the league of i0n1c and Winocm, we now have three different explots effectively by three different hackers to jailbreak iOS 7.1.1, making it possible on the major iOS device jailbroken on the latest firmware.
Point to be noted: In this video, Jang remotely installs and runs unsigned app on an iPhone 5s, where it cannot reboot without being connected to a computer and assisted by a special recovery app, which in return claims as a “tethered jailbreak”.
i0n1c and osxreverser have confirmed the jailbreak as legit themselves in tweets they sent out earlier:
“Three known private jailbreaks for 7.1.1. The “community” must be really pissed off ahahhahah this is beautiful to watch
i0n1c on Twitter:
I welcome @blue9057 to a world of pain
And according to Yeongjin, this is what he did to achieve the jailbreak:
The work includes followings. 1. Bypassing sandbox, 2. Getting root permission, and 3. bypassing codesign”
However, that doesn’t mean a public tool to jailbreak iOS 7.1.1 will be released anytime soon, as hackers may be more interested in keeping the vulnerability private until iOS 8 rolls out, so that Apple can’t quickly patch it up with a following update.
Prior to the aforementioned Yeongjin’s tethered iOS 7.1.1 jailbreak, an untethered means that a device can be rebooted over and over without the hassle to connecting to a PC or Mac to boot tethered, which is all by means a considerable option.
Want to see a publicly-released untethered jailbreak for iOS 7.1.x, but the iOS 8 launch nearing, that makes i0n1c and Winocm save exploits until the arrival of the next-generation iOS firmware. The Cupertino outfit is expected to take the wraps off its next major mobile software release, just after a couple of months in beta, should hit GM (Gold Master) stage around early September.
