You know, if you would research before just blindly taking an OTA (as has been discussed for YEARS now), you would have known that you should have avoided the Kit Kat OTA if you are on a locked bootloader.
Now, you have to sleep in the bed you made. You are stuck. There is NO going back to unlock it and there is no way to root KitKat on a locked bootloader.
I think I'm going to stay away from these forums for awhile until this all dies down. It's amazing how many people just fail to do a simple search and read and they would find the answers so much quicker than waiting on someone to reply.
