Technology of iPhone Jailbreak
Jailbreaking an iPhone allows you to gain more control over the device and install unofficial apps and modifications. Please note that jailbreaking your iPhone can void your warranty and may have security implications. Additionally, this guide is based on the knowledge available up until September 2021, so the specific methods and tools mentioned may have changed. Nonetheless, here’s a general guide on how to jailbreak an iPhone in five steps:
Check compatibility and backup your data
Before proceeding with a jailbreak, it’s essential to check the compatibility of your iPhone model and iOS version with the available jailbreak tools. Additionally, backing up your data is crucial to ensure you have a recent copy in case anything goes wrong during the jailbreak process. Here are the steps to check compatibility and backup your data:
Identify your iPhone model: Go to “Settings” on your iPhone, tap on “General,” and then select “About.” Look for the “Model” or “Model Number” entry to determine your iPhone model (e.g., iPhone X, iPhone 11, etc.).
Note down your iOS version: In the same “About” section, check the “Software Version” entry to identify the version of iOS running on your iPhone (e.g., iOS 14.5, iOS 15, etc.).
With this information, you can research the latest jailbreak tools available and verify if your iPhone model and iOS version are compatible with them. Visit trusted websites, forums, or jailbreaking communities to find information about supported devices and iOS versions.
Backup your data
iCloud backup: Connect your iPhone to a stable Wi-Fi network and go to “Settings.” Tap on your name, select “iCloud,” and then choose “iCloud Backup.” Enable the iCloud Backup option if it’s not already enabled. Tap on “Back Up Now” to initiate an immediate backup. Ensure your iPhone remains connected to the Wi-Fi network until the backup process completes.
iTunes backup: Connect your iPhone to your computer and launch iTunes (for macOS Mojave or earlier) or Finder (for macOS Catalina or later). Select your iPhone when it appears in the iTunes or Finder window. Under the “Backups” section, choose “This computer” and click on “Back Up Now.” Allow the backup process to finish.
It’s crucial to have a recent backup so that you can restore your data in case something goes wrong during the jailbreak process or if you decide to revert to the stock iOS version later on.
Once you have verified compatibility and backed up your data, you can proceed with the jailbreak process using a suitable jailbreak tool and following the remaining steps mentioned in the previous response. Remember to stay updated on the latest methods, tools, and precautions before attempting to jailbreak your device, as the jailbreaking scene can change over time.
Choose a jailbreak method
Choosing a specific jailbreak method depends on several factors, including your iPhone model, iOS version, and the current state of the jailbreak community. Since my knowledge is based on information available until September 2021, I can provide you with a general overview of some popular jailbreak methods at that time. However, it’s essential to research the latest jailbreak tools and methods for your specific device and iOS version. Here are a few examples of popular jailbreak methods:

Additionally, always exercise caution and ensure you understand the risks associated with jailbreaking, as it can void your warranty, introduce security vulnerabilities, and potentially lead to stability issues on your device.
Disable Find My iPhone and passcode
Before attempting to jailbreak your iPhone, it’s generally recommended to disable the Find My iPhone feature and the passcode on your device. Here’s how you can do it:
Disable Find My iPhone:
Open the “Settings” app on your iPhone.
Tap on your name at the top of the screen to access your Apple ID settings.
Scroll down and select “Find My.”
If the “Find My iPhone” feature is enabled, tap on it to access its settings.
Toggle off the “Find My iPhone” switch and enter your Apple ID password when prompted to confirm.
Disabling Find My iPhone is necessary because some jailbreak methods may require you to turn off this feature to ensure a smooth jailbreaking process.
Disable the passcode
Open the “Settings” app on your iPhone.
Scroll down and select “Face ID & Passcode” or “Touch ID & Passcode,” depending on the authentication method your device uses.
Enter your current passcode when prompted.
Tap on “Turn Passcode Off” or “Disable Passcode.”
Confirm your decision by entering your passcode again, if required.
Disabling the passcode is important because it can interfere with the jailbreak process and cause issues during installation or device boot-up.
Remember to re-enable Find My iPhone and set a new passcode after the jailbreak process, as these security features help protect your device and personal data.
It’s important to note that the steps to disable Find My iPhone and the passcode may vary slightly depending on your iPhone model and the version of iOS you’re using. If you encounter any difficulties, refer to the Apple support website or consult the user manual for your specific device model.
