FAQs: Common Errors and Problems when Jailbreaking

Q4. How to Solve the -20 Error when Jailbreaking iPad on iOS 14.5 and 14.6?

For the iPad Pro 12.9-inch and iPad mini4 models, when jailbreaking iOS14.5, 14.5.1, and 14.6, Error -20 will appear, which leads to the final jailbreak failure (as shown above).
