Therefore, the A11/12/13/A14/A15/A16 jailbreak was much harder. Because the ARM version 8.3 -A pointer authentication removes a lot of exploit vectors & makes exploitation process as hard as A12/A13. To fool users, the Checkra1n 2022 – 2023 website claims it’s been working with iOS jailbreaker “CoolStar” and even Google security researcher Ian Beer, on a jailbreaking tool. The site also claims Checkra1n will work on the latest iPhone models installed with the A12 – A13 – A16 processors and that it requires no connection to a PC with all false statements.
We are aware that it took a long time to release the A12/13 powered iPhone XS Jailbreak for iOS 15.2 while other devices have jailbreak. Apple has also improved the security of iOS 15.3 to prevent jailbreaking and other hacking methods. iPhone 6S/6S Plus, SE (1st)7/7 Plus8/8 Plus, X, XR, XS/XS Max11, 11 Pro/11 Pro Max, SE (2nd)12/12 mini12 Pro/12 Pro Max 13/13 mini13 Pro/13 Pro Max.

iPhone 11 series are powered with Apple A13 Bionic chips. A13 Bionic is a 64-bit ARM-based system on a chip. It designed a 64-bit ARMv8.3-A six-core CPU, with two high-performance cores running at 2.65 GHz called Lightning and four energy-efficient cores called Thunder. When we compare the previous A12, it’s more powerful in every way.
Also, a very rare uncatchable bootroom-level security exploit called checkm8 exists on Apple’s A5 to A11 chips. It was released as Checkra1n Jailbreak using checkm8 exploits. It’s not affected by these A13 as well as previous A12 processors.
However, at the moment it has successfully achieved A13 jailbreak because of the tpf0 exploit that works on A13 powered iPhones. Now Taurine Jailbreak & Unc0ver jailbreak support added all the A13 devices and A12 devices up to iOS 15.3.
