On each boot, the iOS device startup sequence is modified and is booted into its original, non-jailbroken state. If the owner wishes to jailbreak their device again, they can do so with the help of an app running on the iOS device such as the Electra app. If you’re looking to read more about tools that can help when you jailbreak your iOS device, we have a guide talking about the Cydia Impactor.

By jailbreaking, you are freeing it from limitations by Apple. Freeing your iOS device means that you can install applications that are not from Apple’s iTunes App Store and you can modify different settings that are prohibited to regular iOS users. Jailbreaking your device also means that you can unlock the phone and make it available to other mobile network carriers.

Take note that Apple warns against jailbreaking your iPhone and other iOS devices. Jailbreaking is done through a series of kernel patches. This jailbreaking allows root access to iOS, allowing the downloading and installing of third-party applications and extensions which are unavailable through the official Apple App Store.

Why Choose Unc0ver Versus Others?

As mentioned, the Unc0ver jailbreak is a semi-untethered program and this is the main reason why most people choose this over other jailbreaks. A semi-untethered jailbreak will not require you re-jailbreak your phone as long as you have the unc0ver program.  After a reboot, you just need to open the app and press the jailbreak button.

You also need to keep in mind that it doesn’t mean that you won’t be able to install the application through a computer in your device, you can do this as well. Both methods will be shown below: installing unc0ver jailbreak with no computer and installing unc0ver jailbreak with a computer. It will be explained step by step so you don’t need to worry about this. There will be also an installation guide for those devices running on iOS 12.

Back-Up Your Device

Before jailbreaking your phone, never forget to back-up all your files and data. There are several ways to do this. You can use iCloud to back-up your phone without the use of cables and a computer. You can also connect your iPhone to iTunes which will then back-up your device. Lastly, you can use a Macbook with the Catalina OS update to back-up your device via Finder.

Make sure that you run a backup on your device when preparing for the jailbreak process so that all your media files and everything else is stored properly. So that you can run a restore and get everything back once you complete the jailbreak.


Take Note Before Using unc0ver iOS 13.3 Jailbreak

Keep in mind that this is a public beta version of jailbreak iOS 13 and not a full-fledged jailbreak. This only means updates will keep coming to make it better and flawless. It is still relatively safe to use as a jailbreak tool. However, it is better to wait for a final, refined version that is more stable and reliable. Before you install tweaks, make sure that those tweaks are updated to work with iOS 13.3 jailbreak. Because it may cause issues if you install old tweaks.


A Warning

Make you do not have any downloaded Over The Air (OTA) updates on your device. If you do, go to Settings > iPhone Storage, here you will find any downloaded OTA updates and delete them, because it may cause problems in the process. It is important to remove these before you attempt iOS 13 jailbreak. Aside from that, if you have the RootlessJB (Jailbreak), which was released previously for developers only, be sure to remove that as well from your device completely.


How To Unc0ver Jailbreak iOS 13 Using A Computer

The first method of installing unc0ver is through the use of a computer. In this method, you will need to use AltStore to get the unc0ver jailbreak. If you are worried about how you would install it without a computer, the next method will cover this step by step guide on how to install unc0ver with no pc or computer.

The reason that we are using this method is that you don’t have to resign the unc0ver jailbreak manually every seven days. It will resign the application after seven days automatically if you keep the server open. You can get the AltStore on both Windows and macOS so you won’t need to worry about what computer you should use in this method. Just follow the process for installing and setting up the AltStore server carefully. If you want to know more about iOS 13 before you proceed, you can read our article talking about Apple’s recent major update.


Primary Steps

  • The first thing you need to do before downloading the AltStore is to make sure that you have downloaded both iTunes and iCloud on your Windows computer if you’re using this or macOS computer. If you don’t have these, install them first. After that, go to the AltStore website and download the setup according to your operating system and install it on your computer.
  • This is very important; your AltStore server must be on the same network as your phone. If not, AltStore won’t be able to sign unc0ver automatically on your device. There are no revokes and no expires as the server is online at least once a week, and you connect your phone on the same computer with the same wifi network. It will resign the application after seven days in the background if you are on the free developer account.

  • To be able to install the AltStore connect the device and go to this location shown in the image below. When you hover over the “Install AltStore” option, it will show you the device.

  • Press the “Install” button after you have put in your details. The popup will disappear and after a few seconds, another window will appear at the System Tray stating that the AltStore is installed on your device. Just like Cydia Impactor, it will be installed on your computer and you will need to open the service at least once a week.
  • After this, the application will now be installed on your device. BE sure to trust it from the settings otherwise you won’t be able to open the app. Apart from unc0ver, you may get many other applications as well from AltStore. The reason why we are using this app to get unc0ver is that it is declared as an official way to get unc0ver. Right now, the Cydia Impactor is not working so this is the best method we can use for now.


After installing AltStore

  • Now that we have the AltStore server setup, we will now install unc0ver jailbreak on iOS 13 on the device. AS mentioned, the device and your computer should be under the same wifi network, and the AltServer must be running on your computer as well because it’s your computer that will sign the application. Open the AltStore and then access the unc0ver.dev website to download the unc0ver jailbreak file.
  • Once the file is downloaded, open it and tap the arrow above. Next, you will need to scroll to the right side and press the “More” button. Find the “Copy to AltStore” option to proceed. Now, you will be able to install unc0ver directly through AltStore. Once the installation starts, you will see a progress rolling bar at the top of the AltStore screen. It will resign the application automatically every seven days, just make sure that you open the server on the computer with the same wifi network once a week and it will do the rest.
