Hi

can anyone help, I've just upgraded to the latest nightly build of 10.1 from 7 but since updating the login screen comes up and asks me to draw a pattern to unlock. I never set a pattern so have no idea.

Is this a known problem, what should I do?

reboot to recovery and wipe dalvik/cache and data partition
