The yalu jailbreak now supports all 64-bit iOS devices except for the iPhone 7. Unfortunately, the iPhone 7 may never be supported; however, you can follow iClarified on Twitter, Facebook, Google+, or RSS to be notified if is.
Yesterday Apple stopped signing iOS 10.2 which means you cannot upgrade, downgrade, or restore to the firmware using iTunes. If you've already saved your iOS 10.2 SHSH blobs you may be able to downgrade your device. We'll have some more details on that soon.
You can download Yalu 10.2 from the link below.
