A couple of weeks back, Apple came out with the iOS 13.2.3 update. Until now, it hasn’t been possible to jailbreak iOS 13.2.3 using Checkra1n, but now, the developers behind the software have updated the tool to support the latest iOS update as well. If you don’t know how to use this checkm8-based exploit, then detailed below is how to jailbreak iOS 13.2.3 using Checkra1n.
Checkra1n adds support for iOS 13.2.3
The team behind the checkra1n jailbreak has now updated the tool to support iOS 13.2.3, and have released the same publicly as well. You can now download the Checkra1n 0.9.6 beta for Mac iOS 13.2.3. Prior to this update, checkra1n supported iOS 13.2.2, but after the release of iOS 13.2.3 by Apple, the checkra1n team was always expected to add support for the latest iOS version as well.
The checkra1n jailbreak is based on a powerful exploit, called checkm8. This exploit is not limited to a firmware version, but rather is bootrom-based. This means that the exploit executes into the device even before the OS comes into action. Also, Apple can’t patch it. Along with being powerful, this jailbreak supports all devices from iPhone 5s, or all devices running on Apple’s A5-A11 processor.

A point to note is that even after the latest update to checkra1n, the tool still carries the “beta” tag. So, we are still to see the official 1.0 version of this jailbreak tool. Since it is in beta, there are always chances of something going wrong, so it is recommended that you don’t use it on your primary device.
The chances of things going wrong are very slim, considering the amount of testing that the Checkra1n team is carrying out and the huge numbers of users that have already used this jailbreak tool. Still, it is always better to take precautions.
