This worked for me. But in the oddest way actually. I was at a family party and friends would keep snatching my phone, so I put a lock on it. For some reason however, i'm guessing the Google keyboard had a glitch when I was putting in the pin and it completely misinterpreted what I input... twice? Anyways, I set it all up and locked my phone and thought nothing of it. When I pressed the home key to turn my screen on, I tried putting the code in and it locked me out. Terrified I had no backup of ANYTHING, I didn't know what to do. So I reflashed my ROM without wiping, and it didn't work. So I reboot my phone trying to see if it'll help, and the lock pin and clock were gone but I had my finger on the screen and the flare effect happened. I slid the screen and it worked. So I re-tried this a few extra times and it still worked. Backed everything up, got home and wiped away.
I'd never think I'd say this but, wow that bug SAVED my ass!
