Usage
All you have to do is head to the blackra1n website and download the application on to your computer. Then, plug in your iDevice and press 'Make it ra1n'. Then you wait. As this is a tethered jailbreak, the iDevice may not boot. If is does not boot, just press 'make it ra1n' again. This should only happen with newer iDevices, though. These are the updated (after week 40, 2009) iPod touch (2nd generation) (MC Model), iPhone 3GS and the iPod touch (3rd generation). These devices have updated bootroms that are not vulnerable to the 0x24000 Segment Overflow.
Installing Package Managers
The Blackra1n procedure installs an App on to the device, aptly named 'Blackra1n' that handles the package manager installation. With it you can install Cydia or Rock. After installation, the device will respring and the package manager of your desire will be on your SpringBoard. After installing, you may remove the Blackra1n App using the 'uninstall' button within it. Don't worry - this does not remove the Jailbreak, just the App to install Package Managers if you no longer need it

Integration with Blacksn0w Unlock
On the iPhone 3G and iPhone 3GS, there is an additional section called 'Sn0w'. If you install this, it will unlock your 05.11.07 baseband after which it will restart your CommCenter - no reboot required. This unlock is detailed on the Blacksn0w page. If you need an unlock on the iPhone, use BootNeuter as it will always work with every firmware.

Q: What is checkra1n? A: checkra1n is a community project to provide a high-quality semi-tethered jailbreak to all, based on the ‘checkm8’ bootrom exploit.
Q: How does it work? A: Magic hax.
Q: Why was the beta release delayed? A: We didn't want the release quality to end up like iOS 13.2, you deserve better.
Q: wen eta? A: bruh we're past that.
Q: How do I use it? A: Open the checkra1n app, and follow the instructions to put your device into DFU mode. Hax happens auto-magically from that point and the device will boot into jailbroken mode. If you reboot the device without checkra1n, it will revert to stock iOS, and you will not be able to use any 3rd party software installed until you enter DFU and checkra1n the device again.
Blackra1n Download Mac Os
Q: Ugh, I don't like GUI? A: Ok, you can use './checkra1n.app/Contents/MacOS/checkra1n -c' from the console, or download a Linux CLI build.
Q: Is it safe to jailbreak? Can it harm my device / wipe my data? A: We believe jailbreaking is safe and take precautions to avoid data loss. However, as with any software, bugs can happen and *no warranty is provided*. We do recommend you backup your device before running checkra1n.
Q: I have a problem or issue to report after jailbreaking. A: Many problems and bootloops can be caused by buggy or incompatible tweaks. Remember many tweaks never saw iOS 13 in the pre-checkra1n era. If you suspect a recently installed tweak, you may attempt to enter no-substrate mode by holding vol-up during boot (starting with Apple logo until boot completes). If the issue goes away, a bad tweak is very likely the culprit, and you should contact the tweak developers.
Q: I have a problem or issue to report and I don't think it's related to a bad tweak. A: Please check here and follow the bug report template.
Q: I lost my passcode. Can checkra1n decrypt my data or get access to a locked device? A: No.

Q: Can I ssh into my device? A: Yes! An SSH server is deployed on port 44 on localhost only. You can expose it on your local machine using iproxy via USB.
Q: I love the project! Can I donate? A: Thanks, we love it too! The project does not currently take any donations. If anyone asks for donations, it's a scam.
Q: Where are the sources? I want to write a dark-mode theme and publish the jailbreak as my own. A: checkra1n is released in binary form only at this stage. We plan to open-source later in 2020.
Q: When is Windows support coming? A: We need to write a kernel driver to support Windows (which is a very complex piece of code!) which will take time. Rest assured however, we are working hard on it.
