  • Linux GUI build when using CLI mode doesn’t support auto assertion of DFU mode on advanced Apple TV 4k breakout boards

Unsupported platforms

This beta is only available for macOS and Linux. Work is ongoing to support Windows, which will be added in a later release.

Package managers

At the moment, checkra1n only supports installing Cydia. Support for other package managers, including Zebra and Installer is coming soon and is expected within the coming weeks.

Checkra1n working on iPhone 6S running the iOS 14.6 beta. I haven’t noticed any problems related to the jailbreak so far, and this should work with 14.5 too. The only real issue I have faced is you have to put it into recovery mode manually rather than it letting you switch to recovery from the OS. I’ve heard some people have had issues with A10/A11 because of the SEP thing. You can try it, but I can’t guarantee it works!

Checkra1n working on iOS 14.6 beta 1 on the iPhone 6S with (PongOS)

You will need a computer running macOS or Linux. I recommend macOS though, I’ve had issues with Linux when compiling the pongoOS. You’ll also need git installed, and if you are on macOS you will need the Xcode command line tools too. Open up a terminal and run:

git clone https://github.com/checkra1n/pongoOS.git

cd pongoOS

make all

If you’re on Linux, you’ll need to run the following first: (this is only for Debian/Ubuntu)

echo 'deb https://assets.checkra.in/debian /' | sudo tee /etc/apt/sources.list.d/checkra1n.list

sudo apt-key adv --fetch-keys https://assets.checkra.in/debian/archive.key

sudo apt-get update

sudo apt-get install -y ld64 cctools-strip

Now go to the build folder in your pongoOS repo, you should find several .bin files. The one we want is called “PongoConsolidated.bin”

Download the latest version of checkra1n from http://checkra.in if you haven’t already. Close the terminal you are in, and open up a brand new one. If you’re on Linux, then cd to the directory you store checkra1n in, and then run:

sudo ./checkra1n -c -k (drag and drop PongoConsolidated.bin)

If you’re on macOS,  then run:

cd /Applications

./checkra1n.app/Contents/MacOS/checkra1n -c -k (drag and drop PongoConsolidated.bin)

Now plug in your iPhone and put it into DFU mode. To do this, press down the power and home button for ten seconds, then release the power button and keep holding the home button until checkra1n starts the exploit. Your device should be jailbroken and boot up successfully, with no kernel panics or anything. After about a minute the checkra1n app will appear, you can now jailbreak your device and install Cydia (if you haven’t already). Enjoy!
