How To Jailbreak iPhone 5 8.0 iOS

• Pangu 8 supports iOS 8 – iOS 8.1 devices

Steps
Download pangu from any of the links:
 
 Pangu for iOS 8.0-8.1
Pangu for iOS 7.1-7.1.X


Warning: do not update to iOS 8.3 - a jailbreak is only available for iOS 8.0-8.1.2

•  Connect your device to your computer using the USB cable.

• Use iCloud or iTunes to back up any and all personal information that you need to keep safe. The jailbreak works well in most cases, but it’s a good idea to have an escape plan.
• Disable any Anti-virus programs or firewalls that could prevent Pangu from connecting to the internet

•  Enable Airplane mode, Disable Passcode from Settings > Touch ID & Passcode and turn off Find my iPhone from Settings > iCloud > Find my iPhone.

• Launch the application as an Administrator. Right Click on the Pangu exe and select the “Run as Administrator” option.
• Pangu will take some time to detect your device. Once that is done, click on the blue “Start Jailbreak” button.

•  Click on Already Did to proceed to the jailbreak.

 

• Wait for the progress bar to complete. Your iPhone or iPad will reboot.

 

• Once the process completes, you should see the Cydia icon on your home screen as it is in the first image on this thread.

Enjoy your jailbreak
