unc0ver 5.0.1

Summary

In this phase, we will be jailbreaking our iOS 13.5 device with unc0ver 5.0.1. I did this on Windows using AltStore, but there are instructions on the unc0ver website on how to do this on iOS, macOS, Windows, and Linux. Some methods cost money ($100/yr for an Apple Developer account) or require you to already be jailbroken. This method requires neither.

Required Software

You will need to download and install the following software:

I won't walk through the installation since it's pretty standard affair. Install them all and make sure they run. To confirm AltStore has properly been installed, check for it (a diamond icon) in your Windows taskbar. You will need to run it first before it will appear here.

Install AltStore

Open iTunes and make sure your iDevice is connected.

iTunes iOS 13.5

Click on the AltStore diamond in the Windows taskbar, and click Install AltStore => <iDevice Name>.

Install AltStore

Enter your Apple ID username and password.

You might be prompted to install iCloud if it isn't already installed.

You will then be prompted to enter your 2FA pin.

AltStore MFA Pin

From here, you should have the AltStore icon on your iPhone.

AltStore Installed

Install unc0ver 5.0.1

In Safari on your iDevice, navigate to https://unc0ver.dev and click Download v5.0.1. Save the unc0ver-v5.0.1.ipa to your iDevice and open AltStore.

unc0ver on Safari

Click the My Apps option at the bottom and the + icon in the top left corner. Select unc0ver-v5.0.1.ipa and install it.

AltStore - My Apps AltStore - Files - unc0ver

You will now see its icon on your iPhone, however, if you try to run it, it will say it was created by an Untrusted Developer.

unc0ver - Untrusted Developer

Go to Settings => General => Device Management => <your email> and click Trust "<your email>". Click Trust on the prompt. It should now open properly.

Jailbreak

Open the unc0ver app and click Jailbreak.

unc0ver - First Run

It will prompt you that you will need to reboot to finish the jailbreak process. Click OK.

unc0ver - First Result

Open the unc0ver app and click Jailbreak again.

It will prompt you that No error occurred and that the device will reboot into the jailbroken state.

Cydia

One of the hallmarks of a Jailbroken iDevice is the Cydia application. This should now be present on your homescreen.

Prohibit Future Updates

I highly recommend that you stop your iPhone from updating if you wish to say on the jailbreakable 13.5. There is a bug in unc0ver 5.0.1 that makes this a little counter-intuitive. If you open iOS Settings => General => Software Update, you will see that 13.5.1 is available. This should not happen.

13.5.1 Update Available

First, let's stop it the "official" way and click on Automatic Updates and set the toggle to Off.

Disable Automatic Updates

Now let's do it the unc0ver way for additional protection. Launch the unc0ver app and select the cog in the top left corner. Note that the Disable Auto Updates toggle is currently Blue (On). You must turn this to Black (Off) in order for updates to be stopped. I know this is backwards. This is the bug I mentioned earlier. Click Done and click Re-Jailbreak.

Now when you go to iOS Settings => General => Software Update, you will see that it was Unable to Check for Update. This is the desired state and you are now safe.
