I accidentally deleted the stock lock and when I shut off my screen, I had a stock jelly Bean like lock screen. The unlock button wouldn't work, but I could unlock with a notification. The pattern lock worked but it was completely and I couldn't change the back ground. Pin Lock soft booted and then bricked. But it displayed music widgets when playing. So I restored an old backup and I figured I'd do it again and take a picture of it before I reinstalled everything. I wonder if we could enable it how.
