This video will be showing you how to jailbreak iOS 8.4 untethered using the latest jailbreaking tool PP Jailbreak, that also work with iOS 8.3 and show you how to install Cydia. This is fully working on iOS 8.4 without any sort of issues. The PP jailbreak they’re using an unauthorized version of TaiG exploit. Of course this isn’t fair to TaiG, but it is the fastest jailbreak that is out and this video will show you how to jailbreak 8.4. Now that doesn’t mean you have any issues that just means that TaiG team didn’t let them use their exploit but they release their version of the tool anyways. Now once TaiG does release their version of the iOS 8.4 jailbreak I will update the links but for now this is the PP Jailbreak for 8.4. Now I would recommend you guys go ahead and update iOS to 8.4 in order to jailbreak.
Update: TaiG now jailbreak iOS 8.4 on Mac OS
