While Apple's iOS release is knocking at the door, jailbreakers are not keeping quiet. Despite declaring iOS 8.4.1 jailbreak-proof, famous jailbreak community Pangu has apparently developed an untethered solution for the same. But since Apple is about to launch its latest operating system version iOS 9 on Wednesday, Pangu is a little sceptical about releasing the rumored iOS 8.4.1 update.
Meanwhile, another jailbreak team called Semijb has managed to break the iOS security system to released an iOS 8.4.1 jailbreak. Pangu has posted a blog in its website mentioning Semijb as a partial jailbreak that shouldn't be installed on iPhones running on iOS 8.2, iOS 8.3 or iOS 8.4 with TaiG2 or PP Jailbreak. The Semi jailbreak is only applicable to iPhone with iOS 8.4.1. However, the Semi jailbreak process will allow you to install Cydia on your device.
Pangu has claimed to discover the 0Day kernel vulnerability in "AppleHDQGasGaugeControl", which is meant to control the battery operation of the iOS running device. Though Apple had patched the vulnerability in its iOS 9 beta release, it still remains accessible to the jailbreakers.
Pangu has also mentioned to avoid the iOS 8.4.1 jailbreak as of now and even if you have updated your iPhone to iOS 8.4.1 its better to downgrade the device now to iOS 8.4 as Apple might disable the downgrade option soon. But if you save your SHSH blobs under TinyUmbrella, you can downgrade the device anytime you want to.
