Using checkn1x requires creating a bootable USB drive, booting your PC into it, and putting your iOS device into Device Firmware Update (DFU) mode. Step 1: Prepare Your Tools
Use Rufus (or BalenaEtcher). Select the ISO, write it in "DD Image" mode when prompted. On macOS/Linux: Use dd command:
For advanced users, checkn1x includes a build script that automates the entire image creation process. By defining a simple variable, users can pin specific checkra1n builds or update components as needed, creating custom ISOs for specialized requirements.
: Jailbreaking your device comes with trade-offs. Always ensure you have adequate backups, understand the security implications, and proceed at your own risk. But for those who make the informed choice to jailbreak, checkn1x provides one of the most efficient and reliable paths to get there—all from a USB drive small enough to fit in your pocket. checkn1x-1.0.6-amd64.iso
If you receive an alert stating “Sorry, iPhone (5s-X) is supported, but iOS is not,” navigate to the “Options” menu using the keyboard arrow keys and enable “Allow untested iOS/iPadOS/tvOS versions.” This bypasses the version check and allows the jailbreak to proceed.
Use the arrow keys on your keyboard to navigate the checkn1x menu.
: Obtain the checkn1x-1.0.6-amd64.iso from a trusted source (usually GitHub). Using checkn1x requires creating a bootable USB drive,
The specific filename checkn1x-1.0.6-amd64.iso contains important information:
Get the .iso file from a trusted source like the Official checkra1n releases or specialized developer repositories.
Restart your PC and enter the Boot Menu (usually by pressing F12, F11, or Esc). Select your USB drive. On macOS/Linux: Use dd command: For advanced users,
: Use a tool like Rufus or BalenaEtcher to "burn" the ISO onto a USB drive. Note: This will erase all data on the USB.
When prompted, select “Write in DD image mode” and click “OK”. Rufus will warn that all data on the USB device will be formatted—confirm and proceed. The writing process takes approximately 2-3 minutes.
: Upon booting, the system directly initializes the checkra1n terminal user interface (TUI). Users do not need to interact with a Linux command line or input manual login credentials.
: If you own an iPhone X on iOS 16 (which is not possible – iPhone X max iOS is 16.7.10), wait—correction: The iPhone X caps at iOS 16.7.10, and checkm8 works there. checkn1x is the only way to jailbreak iOS 16 on an iPhone X.
