Why is Chimera so special?

  • Chimera supports for all iOS devices including A12 devices. Uncover, Rootless iOS 12 - iOS 12.1.2 jailbreak tools didn't support for iPhone 5S as well as partially support for A12 devices.


  • Chimera is installed Sileo automatically after the Jailbreaking process. You cannot install Cydia from Cimera.Sileo is the Jailbreak app manager for latest iOS versions and latest device models such as A12. Currently,Cydia not supported for A12 devices and there is no any hint about Cydia A12 update from Saurik.Therefore Sileo is the only solution for A12 devices.


  • Chimera Jailbreak doesn't affect for any user files. Therefore Chimera more safe, and more speed than Uncover and Rootless Jailbreak. Also It does waste your battery as the previous Jailbreaking methods.


  • Chimera is Crash free Jailbreak. It’s less bugs when we compare with previous iOS 12 Jailbreak such as Uncover & Rootless.


  • It's 100% free forever

Why Sileo? No Cydia

Sileo is a new modern package manager. You can install & manage packages easier with Sileo. Also, it is a development of CoolStar and the Electra team. All of them are active members in Jailbreak community.


They introduced Sileo because Saurik does not update Cydia continuously. He took a long time to update against jailbreak release too. As well If there is an Unc0ver Jailbreak for iOS 12 & higher Jailbreak, still Cydia substrate does not added support for A12 devices. It seems Cydia is no longer updated by Saurik.


Therefore Sileo is better than Cydia for latest iOS versions & device models. It will be updated simultaneously with every Chimera / Electra and the other Jailbreak updates.
