Less than a week after teasing an iOS 14 – iOS 14.3 jailbreak for iPhone 12 and lower devices, @ Pwn20wnd released Unc0ver 6.0 to the public. This is the first public release of an iOS 14 – iOS 14.3 jailbreak that supports newer iPhones like iPhone 12, iPhone 11, etc.
This is a full-fledged jailbreak version because it offers tweak injection via Substitute and Cydia for package management. Unc0ver uses an implementation similar to the cicuta_verosa exploit which was detailed recently by @ModernPwner. CoolStar of the Odyssey Jailbreak Team is working on an iOS 14 – iOS 14.3 jailbreak based on the cicuta_verosa exploit.
If you have an iPhone or iPad running iOS 14 – iOS 14.3, you can jailbreak it using the latest version of Unc0ver. The Checkra1n jailbreak was already capable of jailbreaking iOS 14 – iOS 14.3, but it only worked on iPhone X, iPhone 8, iPhone 7, and iPhone 6s, leaving newer iPhones in a mess. Unc0ver, however, has no such restrictions. Keep in mind that since this is the first version of the jailbreak, it can be a bit buggy and there might be some instability issues.
Unfortunately, if your iPhone is already running iOS 14.4, there is no way you can downgrade it to iOS 14.3 or another older version of iOS 14. This is because Apple does not sign any of the older versions of iOS 14 anymore.
To jailbreak your iPhone with Unc0ver, you will first need to install the app on your iPhone using AltStore. Once installed, you can proceed to jailbreak your iPhone under iOS 14 – iOS 14.3. Once you’re done jailbreaking your iPhone, be sure to check out the best iOS 14 – iOS 14.3 Cydia tweaks to try out some amazing jailbreak tweaks.
