Download CheekiJailbreeki – PoC Jailbreak for iOS 10.2.1

A relatively unknown Dev Team has just released a “PoC” jailbreak for iOS 10.2.1 firmware. Here’s how you can download it.

  • Update (October 5) – You can download a working jailbreak for iOS 10.2.1 here.

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.


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.
