: iPhone 5s, iPhone 6 / 6 Plus, iPhone 6s / 6s Plus, iPhone SE (1st Gen), iPhone 7 / 7 Plus, iPhone 8 / 8 Plus, and iPhone X.
Once the Linux environment loads, checkra1n should automatically open. Step 3: Jailbreak Your iOS Device Connect your iPhone/iPad to the PC.
: It strips away unnecessary desktop environments, display managers, and extraneous drivers. The image loads in seconds and runs entirely in temporary system memory.
Enter your BIOS/Boot Menu (usually F2, F12, Del, or Esc) and set the computer to boot from the USB drive. checkn1x-1.0.6-amd64.iso
The file is a highly optimized, light-weight bootable Linux image built specifically to deploy the permanent hardware-based checkra1n jailbreak on compatible iOS devices.
It provides a semi-tethered jailbreak. This means if your device restarts, you must boot back into the checkn1x environment on your PC to re-enable the jailbreak .
The checkm8 exploit supports devices running from iOS 12 up to iOS 14 (and some limited iOS 15 iterations depending on the specific checkra1n version tweaks): : iPhone 5s, iPhone 6 / 6 Plus,
Checkra1n should detect your device. If it says "Unsupported iOS version" or similar, you may need to go to and select "Allow untested iOS/iPadOS/tvOS versions" .
Using this tool requires precision. Follow these steps carefully.
The developer community solved this problem by creating . : It strips away unnecessary desktop environments, display
A: Yes, provided you create the USB with Rufus in DD mode with GPT partitioning.
This flexibility is what makes the checkn1x ecosystem so powerful—developers can compile customized ISO images for specific device types or incorporate experimental checkra1n builds.
It allows administrators to thoroughly test network configurations, ensuring they are optimal and correctly implemented.
