After the release of iOS 10.2 Yalu Jailbreak recently, Luca Todesco has now updated the Yalu iOS
10.2 jailbreak to beta 7 with support for the iPad Air 2 and the iPad mini 4.

The updated beta 7 version of Yalu iOS 10.2 jailbreak now supports all 64-bit
iOS devices like iPhone 6s, iPhone 6s Plus, iPhone SE and the iPad Pro. The iOS
10.2 jailbreak is not compatible with iPhone 7 and iPhone 7 Plus.

So if you have iPad Air 2 or iPad Mini 4
or 64 bit iOS devices then you can easily jailbreak your iOS 10.2 running
device with working mobile substrate.
Follow the step by step tutorial on how to jailbreak iOS 10.2
Additionally, Apple has stopped signingiOS 10.2, which means that you cannot downgrade or restore manually to this
firmware, unless you had saved the required SHSH blobs from Prometheus. If you
are on iOS 10.2.1 you cannot go back to iOS 10.2 to jailbreak your device.

You can download Yalu beta 7 .ipa file and Cydia impactor from our download page for iOS 10.2 jailbreak.
