What is unc0ver?
unc0ver is an Electra jailbreak replacement for iOS 11-11.4 Beta 3. It is developed by renowned developers pwn20wnd and Sam Bingner.
This new jailbreak tool offers better stability, compatibility and success rate. It uses Saurik’s Substrate and replaces Comex’s Substitute present in Electra.
Here’s a quick rundown of its main features –
- All exploits in a single app
- Better performance and stability
- Error messages
- No battery drain
- No slowdowns
- Enhanced performance of Cydia
- Automatic root filesystem restore
All in all, it improves upon everything Electra had and is quite rightly the successor to Coolstar’s jailbreak.
However, before you make the switch, keep in mind that this jailbreak is not for everyone and may cause even more issues later on. If Electra is working just fine on your device, you don’t need to switch.
unc0ver is compatible with all iPhone, iPad, and iPod touch devices running any of the following operating system versions –
- 11.4 Beta 1, Beta 2, Beta 3

How to jailbreak iOS 11.0-11.3.1-11.4 Beta 3 with unc0ver
Download and install
Step 1 Download the IPA file of the latest version using the download link above. Alternatively, you can download it directly from Ignition signing service.
Step 2 (Optional) Open Cydia Impactor. If you don’t have this tool installed on your computer, download it from this link.
Step 3 Drag the IPA file downloaded in step 1 to Cydia Impactor’s window. If you are using Ignition, simply tap the Install button and then confirm it to install the app on your device.
Step 4 Wait for Cydia Impactor to install the app on your device. Once the installation completes, the app will appear on your home screen. If you have downloaded the app from Ignition installer, skip this step.
Trust the certificate
Step 5 Now that the jailbreak app is installed on your device, you must launch it. However, opening it right away will cause it to throw the “untrusted certificate” message.
To fix this, go to Settings > General > Profiles & Device Management. As of right now, Ignition is using “i-MD Holdings (Hong Kong) Limited” certificate to sign its apps.
Step 6 Select Trust “i-MD Holdings (Hong Kong) Limited” to trust the certificate belonging to unc0ver. Tap Trust again to confirm.
Jailbreak your device
Step 7 Open unc0ver app from your home screen. Wait for 30 seconds and tap Jailbreak to jailbreak your device.
Step 8 Give the app the necessary permission to restart your device. Wait until it reboots your device and runs Rollectra, which removes tweaks and device’s settings without tampering with the user data (photos, videos, etc). This should take around five to six minutes at most.
Step 9 Open unc0ver app again and wait for about 30 seconds. Tap Jailbreak again and wait for the exploitation to begin. The jailbreak tool will now perform 48 exploitation operations to gain root access on your device.
Step 10 When the progress bar hits “24/48”, the app will prompt you to reboot your device. Tap Reboot, reopen the app and tap Jailbreak once again. Your device will restart at least twice during the process. The number of reboots can be higher if the exploit fails.
Step 11 Cydia will be installed on your device once exploitation finishes. You can then open it from your home screen and install the desired tweaks and jailbreak packages.
Settings and Utilities (optional)
Step 12 unc0ver comes with a comprehensive Settings section that lets you do more than running No Substrate Mode. Most of the options cater to very specific use cases and are useless for the average user.
However, you can use them to access additional features that would otherwise have been missing from your device. Remember, all the important features are enabled by default.
- Load Tweaks – Enables substrate mode.
- Load Daemons – Enables daemons.
- Dump APTicket – Dumps onboard blobs.
- Refresh Icon Cache – Refreshes icon cache. Enable this if an app icon is missing from your home screen.
- Disable Auto Updates – Disables automatic over-the-air updates.
- Disable App Revokes – Disables app revokes.
- Overwrite Boot Nonce – Overwrites the boot nonce.
- Export Kernel Task Port (Unsafe) – Exports the kernel task port.
- Kernel exploit – Selects the kernel exploit.
- Boot Nonce – Displays the boot nonce of your device.
- Expiry – Displays the expiry time of the jailbreak app’s certificate. If you sign the app using your certificate, the expiry time will be seven days. For enterprise certificates from signing services or app installers, your app will remain signed for a year (365 days).
Step 13 There’s also a “Utilities” section that lets you perform certain important actions, namely –
- Restart – Reboots the device.
- Share Diagnostic Data – Shares diagnostic data with the developers, thus helping them in fixing bugs and glitches.
- Open Cydia – Launches Cydia. This option is useful if Cydia is missing from your home screen.
- Get Technical Support – Open the jailbreak Discord server.
- Check For Update – Checks for updates released by the developer.
