Frequently Asked Questions

Q: What is checkra1n Windows?
A: checkra1n is a community project for windows 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.

Q: ugh, I don't like GUI?
A: ok, you can use "./checkra1n.exe/Contents/WinOS/checkra1n" from the console.

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: Why do I still have jailbreak apps present after I used the 'Restore System' option in the checkra1n app and rebooted?
A: This is a known issue with how this functionality works. The apps are not installed anymore, but their icons may stay on the homescreen until iOS rebuilds its icon cache (which we have no control over in non-jailbroken mode).

Q: The checkra1n app doesn't open inside the Windows Package!
A: Follow the instructions in the Package file and drag the app to the Applications folder.
