In today's update, we fixed some major bugs on the Firmware Manager automated Setup.App Patch Creator, and we improved the iOS 10.1.1 compatibility.
iOS 10.1.1 and iOS 10.1 remain the only signed versions at the moment, therefore, we recommend working with them.
We added a new feature to the Firmware Manager so that you can easily see which iOS version is signed and get the IPSW right away.
Also, In this video i will demonstrate the creation of the Setup.App Patch using Firmware Manager.
A bug on the user interface on Windows 10 was also addressed by better memory handling.
This version is v27.0.
