Checkra1n is not an untethered jailbreak. It is a semi-tethered jailbreak. Let me explain what that means.
In the world of jailbreaking, there are primarily three types of jailbreaks: untethered, tethered, and semi-tethered.
An untethered jailbreak is the ideal scenario for jailbreakers. Once you jailbreak your device using an untethered jailbreak, your device will remain jailbroken even after a reboot. This means that you can power off and power on your device without losing the jailbreak. It’s like having permanent access to the world of tweaks, customizations, and modifications.
On the other hand, a tethered jailbreak requires you to connect your device to a computer and run a jailbreak tool every time you reboot your device. Without this connection to a computer, your device will boot up in a non-jailbroken state. Tethered jailbreaks can be quite inconvenient as they restrict the freedom of using your device whenever you want without having access to a computer.
Now, let’s talk about the middle ground, which is a semi-tethered jailbreak, the category checkra1n falls into. With a semi-tethered jailbreak, you can jailbreak your device and enjoy all the benefits of a jailbreak, but the jailbreak is not persistent across reboots.
Once you have successfully jailbroken your device using checkra1n, you will have access to all the tweaks and customizations. However, if you reboot your device, it will boot into a non-jailbroken state. To regain the jailbreak functionality, you will need to connect your device to a computer and run the checkra1n tool again. This process is often referred to as a “tethered boot.”
While this may seem inconvenient compared to an untethered jailbreak, it still offers much more freedom and customization options than a non-jailbroken device. Additionally, checkra1n has gained popularity and a reputation for its stability and reliability, making it a popular choice among jailbreak enthusiasts.
Checkra1n is a semi-tethered jailbreak, meaning you need to perform a tethered boot after each reboot to regain the jailbreak functionality. It may not provide the same level of convenience as an untethered jailbreak, but it still offers a great deal of customization and freedom to users who are passionate about jailbreaking their devices.
