Downgrade iOS 8.2 to iOS 8.1.3 Jailbreak TaiG or PP, How to Tutorial – Ensuing the rather substantive, albeit definitely foreseen, blow to the iOS 8 jailbreak community that was iOS 8.2 (the firmware that patches the TaiG jailbreak), a sizable number of our readers have written us as to whether it’s possible to jailbreak iOS 8.2 Untethered. Unfortunately, as we’ve detailed in great length through a number of recent iOS 8.2 jailbreak articles, the new firmware that was released on Tuesday, January 27th, 2015, patches the primary kernel exploit utilized by TaiG in addition to several others. Simply put, it’s no longer possible to jailbreak 8.2 on any device whether it’s a newer iPhone 6, iPhone 6 Plus, iPad Air 2, iPad mini 3 or an older iPhone 4s or iPad 2 running iOS 8.2. The same applies to any other iOS-based device – it’s impossible to jailbreak iOS 8.2 when utilizing the current TaiG and PP tools. However, there is a silver lining for jailbreakers! Those who updated, either intentionally or by accident, can successfully downgrade from iOS 8.2 to iOS 8.1.3 (the latest firmware supported by both TaiG and PP for Mac). Interestingly, in spite of Apple’s efforts to close the untethered iOS 8 through 8.1.3 jailbreak, the company is still signing iOS 8.1.3, meaning restores to the firmware are still permitted. If you’re interested in downgrading 8.2 to 8.1.3 to jailbreak, continue reading past the break and do so sooner rather than later as this incredible opportunity won’t last long.
Downgrade From 8.2 To 8.1.3 And Jailbreak – Tutorial!
First, as a prerequisite to downgrading, it’s crucial to understand how iOS restores are delivered and verified, if only on a rudimentary level.
Basically, prior to the initialization of the restore process, iTunes identifies a device (the type, model number, etc.), in addition to the IPSW (firmware file), if provided, and checks the information against Apple’s servers to verify whether the device intended for restore matches the firmware(s) the company is currently signing for said device.

While it sounds like it could easily become a complicated process, the checks listed above (in addition to a number of extra steps) occur almost instantaneously and if an individual attempts to restore his or her device to an older firmware that’s no longer being signed for their device, iTunes will return an error message, effectively making downgrades to unsigned firmwares impossible. Furthermore, there used to be a solution to trick iTunes into thinking it was connecting to Apple’s official server by using pre-saved SSH blobs for the desired firmware but due to Apple’s vast and strict security improvements that’s no longer an option; it’s either restore through iTunes by using Apple’s official remote restore servers or nothing at all.
Finally, while Apple is (as of writing this article) signing iOS 8.2, in addition to 8.1.3, that could change literally any second. In light of this rather harsh fact, it’s of the utmost importance that you perform the downgrade to 8.1.3 as quickly as possible to ensure that you won’t be stuck on iOS 8.2 without a jailbreak in sight for what could very well become a painful wait. With everything outlined above in mind, let’s get started!
