i0n1c (Stefan Esser)

i0n1c is very famous as Security researcher for iDevices. In the jailbreak community known as i0n1c and real name is Stefan Esser, released video clip showing his iOS 8.4 beta1 installed iPhone running unique Cydia application as the latest. It was the new concept for iOS 8.4 jailbreak because most of the Developers failed to release proper version for beyond 8.1.2 version. So iDevices users could make hopes for iOS 8.4 full version Cydia installation. Finally, it was able to jailbreak iOS 8.4 version. Pangu, TaiG and PP Jailbreak teams did it successfully. These three teams followed Stefan Esser’s method to find jailbreak tool for iOS 8.4.




Author of the CyberElevat0r tool. Even if, he proved via YouTube video, it is possible to jailbreak iOS 7.1.1 as untethered jailbreak with CyberElevat0r tool, he didn’t release it for the public. Pangu jailbreak team got the encouragement and released Pangu jailbreak version for IOS 7.1 to 7.1.x versions using Stefan method.


Stefan Esser’s jailbreak efforts.

i0n1c publishes his JB magic into the world very rarely. Most important thing is even though he was able to prove installing Cydia is possible or not, he doesn’t publish any jailbreak tool or method for the Cydia lovers. It was a big discussion about Cyberelevator tool. But it wasn’t real.

When talking about Apple iDevices, Apple iOS version, jailbreak iOS versions, Esser is necessary one. He involves into this field directly or indirectly. Here is the his all efforts for the iOS versions jailbreak.




iOS 8.4 beta 01 jailbreak – no mention any tool.

Newly jailbreak effort of i0n1c was iOS 8.4 beta 01 jailbreak. Proved via YouTube video, it is possible to jailbreak it for Cydia. But, it didn’t mention any tool, which used to complete the jailbreak. Then Pangu, TaiG and PP Jailbreak released tool version to jailbreak iOS 8.4



Here is the video proved of iOS 8.4 beta 01 jailbreak.



iOS 7.1.1 Jailbreak –mention about CyberElevat0r tool.

For the first time, i0n1c revealed about the CyberElevat0r tool as a untethered JB tool. But, it wasn’t published. Pangu team got help from @evad3rs and @i0n1c to release Pangu tool for iOS 7.1.1 jailbreak. Pangu team been thankful for i0n1c as well as @evad3rs. But Stefan Esser rejected it by claiming the Pangu team didn’t buy the vulnerabilities never ever to release JB tool.



Here is the iOS 7.1.1 jailbreak video using CyberElevat0r tool.




i0n1c’s Intervention for iOS 10 jailbreak.




First time, i0n1c expressed about iOS 10, when it released second beta version for the public. As the Security researcher, he identified system and security issues of this beta released. i0n1c will research more about this to check availability of jailbreak.

Meanwhile of this, Pangu also has involved for iOS 10 jailbreak too. Get more info about Pangu10 for iOS 10 jailbreak clicking on it.

And also already iH8snow has involved for this case by publishing one of the videos to prove, it can be jailbroken iOS 10 beta 01 version. Because of it is not for iOS 10 original version, have to wait iOS 10 jailbreak with iH8sn0w more.

When it happens all of these things just like this, i0n1c’s jailbreak intervention will be most important for this. If Stefan Esser finds jailbreak method for iOS 10 version, it can be effect for all of the iOS 10 and minor versions of it. As the owner of CyberElevat0r tool, i0n1c has many experiences to find JB tool for any iOS version in any circumstance. However, he gets time gap for jailbreak observations. So, let’s see he will apply his method for iOS 10 jailbreak or not.


Gratitude of TaiG Jailbreak to Stefan

When TaiG released version 2.1.3 to jailbreak iOS 8.4, there was a installing Cydia issue when using TaiG tool. i01nc pointed it. At that time TaiG team mentioned i01nc’s help via twitter after fixed it. Normally, Stefen is famous for doing nothing for Cydia without showing the possibility of download it for the iOS versions. So Cydia lovers lifted him up this time.



i0n1c’s solution for lack of jailbreak.

iOS 9.0 and iOS 9.1 were the last JB attempt. The Pangu team did it. Every time it has the lack of jailbreak in the field, i0n1c gives the solution. When it comes Pangu team for the first time into the JB, they have gotten Steffen’s jailbreak ideas. So, we can keep hope for iOS 10 jailbreak too with the combination of Stefan and Pangu team. And also it has given some push by the iH8snow.
