Yes I did. Installed inception 0.2, installed the unrestricted system ui and then tried to install things from the store and I started getting an error message. I was previously installing things before I installed the unrestricted system ui. Now I'm trying to flash my phone but it's not letting me either. Oh oh...now I'm trying to take care of that issue...or maybe that's because it won't let me downgrade as I'm trying to go back to pr1.2 as that is what I had on my pc.

EDIT: Yep was able to flash my phone and repeated the same process without downloading any other apps, just inception and unrestricted system ui and after that was unable to download any other applications.
