It's finally here! The iPhone SE has finally got a Jailbreak for iOS 10.1.1 and it is also including Cydia. Yalu has been updated to support iPhone SE (with Samsung Chip) and some TSMC devices (iPhone 6S), and it is now available as the Yalu Beta 3 IPA for installation with Cydia Impactor. I also have a tutorial on how to install it, I linked it down bellow but please do keep in mind it is still a Beta.
In this video we also discuss about why there is no new Beta for the moment, why you should NOT install YUCCA Utilities and The Cydia Substrate fix created by ijapija00. No offense to ijapija00, but if the creator of the Cydia (@saurik) and Luca Todesco decided it is not safe at all, then I can't tell people it is. The problem seem to be more between ijapija00 and Todesco, so I recommend you to read the discussions I linked down here to understand the bigger picture and to decide whether you risk using the above mentioned tweaks or not.
