So before I was using WP8.1 DP on my Ativ S and dev unlocked it using Visual Studio 2013 with the phone SDK installed. It seemed hit or miss on whether an app I developed would deploy to my phone when deploying it from my desktop. Some sort of issue saying it couldn't copy. I did have some problems at first with it dev unlocking the phone, but seemed to work after a while. I can now confirm, after rolling back to WP8.0 GDR3 and doing the updates properly to WP8.1.1, and installing visual studio 2015, dev unlocking the phone was seemless, as well as deploying my developed apps to my phone no longer has an issue at all. Just figured I would let anyone still developing for this awesome phone know that things are working as intended!
