Part 2. How to Jailbreak iPhone 5s with Computer

If you prefer a more controlled and less risky method, the most dependable way to jailbreak your iPhone 5s is with a computer. For iOS 12.5.7 on iPhone 5s, we recommend platform-specific tools: 3uTools (Unc0ver-based) on Windows and Checkra1n on Mac. Both are free and community-vetted as of 2025.

How to Jailbreak iPhone 5s on Windows  Using 3uTools

Windows users can hardly find a simpler and more reliable method than 3uTools when it comes to jailbreaking an iPhone 5s running iOS 12.5.7. It is a very approachable software that supports you with file management, installation of jailbreaking tools, and even fixing your system with minimal effort from your side. The stepwise procedure given below will help you to do it properly.

How to Jailbreak iPhone 5s Using 3uTools on Windows:

Step 1. Get 3uTools for your Windows computer from the official website and install it.

Step 2. In case the request appears, set up the necessary parts, like iTunes or device drivers, to be able to detect the device properly.

Step 3. Select “Repair Driver.” Then press the “Repair Now” button when the window appears.

Step 4. You will be able to read the confirmation message once the repair operation is done correctly. iPhone should be reconnected as required. After that, press “Confirm”.

Step 5. Select “Flash & JB” from the 3uTools main menu and then “Jailbreak.” The procedure can be initiated by clicking “Run Jailbreak.”

Step 6. Navigate to Settings > General > Device Management. Then, tap on Developer App and Trust. Launch the Unc0ver application and tap the “Jailbreak” button.

Step 7. After the jailbreak is complete, your phone will restart. You will know the jailbreak was successful if you see the Cydia icon on your device. If the Cydia icon is not present, run Unc0ver again.

How to Jailbreak iPhone 5s on Mac Using Checkra1n

Checkra1n leverages the checkm8 exploit for a reliable semi-tethered jailbreak on A7 devices like iPhone 5s.

Step 1. Get the Checkra1n application installed on your Mac. Press “Start” in the Checkra1n window to continue with the jailbreak.

Step 2. You will be shown a warning message — don’t rush and check it thoroughly before tapping “OK.” After that, click “Next.” Then the Recovery Mode will be set automatically.

Part 3. How to Jailbreak iPhone 5s without Computer

For a no-PC option, use Unc0ver via an online signing service (e.g., zJailbreak or Scarlet) through Safari. This installs the IPA directly but risks certificate revokes—re-sign if needed. As of 2025, it’s viable for iOS 12.5.7 but less stable than computer methods.

Steps to Jailbreak iPhone 5/5s Without Computer：

Step 1. Find and install the jailbreak application

In Safari, visit a trusted signer like zJailbreak.store. Search for Unc0ver v6.1.2 (iOS 12 compatible), download, and confirm installation.

Step 2. Trust the developer certificate

Go to Settings > General > VPN & Device Management > Select Enterprise App > “Trust” > Confirm.

Step 3. Execute the jailbreak

Turn on Airplane Mode first and launch Unc0ver app. Hit the Jailbreak button.

Step 4. Finalize and verify the process

Unc0ver tries to use its exploits one after another. After the jailbreak is done, the device will restart by itself. Find the Cydia icon on your Home Screen – the icon is a visual confirmation of the jailbreak.
