What is CheekiJailbreeki?
CheekiJailbreeki is a proof-of concept jailbreak for iOS 10.2.1 based on Adam Donenfeld’s ziVA exploit. It is developed by Coffeebreakerz Dev Team, who are relatively unknown within the community.
Here’s a list of all actions you can perform using CheekiJailbreeki app –
- Block OTA Updates
- Manage SHSH Blobs
- Set Nonce
- Jailbreak
The one thing that stands out to me is its professional user interface. We don’t often find this kind of interface in modern jailbreak tools anymore.
Here’s how it looks like while running the exploits –
For those who don’t know, its name is a reference to the Russian catchphrase “Cheeki Breeki” used in the S.T.A.L.K.E.R. game. It also contains a lot of references to Eastern Europe and uses a lot of Russian slang such as squatting and Katyusha.
Compatibility
At present, it supports the following 64-bit devices running iOS 10.2.1 firmware –
- iPhone 5S
- iPhone 6
- iPhone 6 plus
- iPhone 6s
- iPhone 6s plus
- iPhone SE
- iPhone 7 (experimental)
- iPhone 7 plus (experimental)
Support for more devices will be added in the future. You can download its ZIP file using the link below and compile it using XCode.

Is this jailbreak fake?
No, being a proof-of-concept doesn’t make a jailbreak fake. CheekiJailbreeki works exactly like a normal jailbreak tool but it won’t install Cydia on your device. The lack of Cydia effectively renders it useless for the average user.
Remember, this tool is still a “work in progress” and not a full-fledged jailbreak. With that said, it does employ both Adam Donenfeld’s exploit and Google Project Zero’s triple_fetch and makes it easy to compile for developers and hackers.
Even if you don’t like this particular tool, you can use it to perform other useful functions.

yas ya no
No.
Though it won’t install Cydia, is it possible to use it to modify some of the system files?
Hello, Rand. Yes, it does that but I wouldn’t recommend using it.
Hello, Rand. It “purportedly” does modify system files but I recommend not to use it.
I mean, doesnt adam’s exploits work on 10.3.1? SO can’t they replace the exploits and it should work, or well also replace the offsets and stuff…. how much more could there be too the jailbreak. If only I had a mac and could try it myself.. lol just trying to see how hard it actually is to create this jailbreak to adapt 10.3.1.
Actually, it does work on iOS 10.3.1 but Luca’s KPP bypass doesn’t. This means you can’t get it working even if you have the right offsets. Also, try creating a Mac VM using VMWare or VirtualBox.
Ok so the kpp bypass is the problem. And my computer is too weak to handle virtual box/VMware. Have already tried that.
Awesome news. Thanks
Welcome.
Couldn’t someone compile this w/ Xcode and share the file? I’ve never done anything like this so I’m just curious.
Yes, they could but it’s useless for the end user that’s why no one has done it in the first place.
