Frequently Asked Questions
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: You download the 'Setup > Connect your iDevice to Windows PC > Enter ECID' and let the Setup do Everything. (Watch Video to Learn More)
Q: Why was the Final release delayed?
A: We didn't want the release quality to end up like iOS 13.2, you deserve better.
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. However you can promote it on social media to support us.
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 Jan 2022.
Q: When is Linux support coming?
A: It will take time. Rest assured however, we are working hard on it. We are expecting realese in Dec 2022.
