How to full untethered Jailbreak iPhone iOS 8.3 Safely [Windows]

Previously, we have discussed “jailbreak” iOS 8.3 using a free application in App Store which injects Cydia Installer. It’s a temporary alternative method we can do at that time because there wasn’t any full jailbreak method yet from hacker team. Moreover, that method can make the Cydia injection on iPhone not good and sometimes there will be found some issues when you run the application that you’ve downloaded from Cydia store. Lack of full jailbreak apps for iOS 8.3 in quite long time was caused by the difficulty to break iOS 8.3’s security system. But, today we got a good news from a popular hacker team: TaiG who also made jailbreak app for iOS 8. They have just released TaiG version 2.0 which can be used to jailbreak iOS 8.3. We’re a bit surprised with the present of TaiG version 2.0 for iOS 8.3 in which previously they said that they will focus on iOS 9. Unfortunately, this version is only available for Windows PC and not yet available for OS X. So, let’s get started to discuss how to full untethered jailbreak iPhone iOS 8.3 safely and you can have your Cydia App store back.
