Just updated L920 from 10136 to 10149 and now stuck at "Change your PIN", supposedly due to my work email requirements. Can enter the first PIN but it won't let me "Confirm PIN". Any suggestions?
You can drop the work email, set your pin through the lock screen settings, then re-add your work email. Seemed to work though it enforces Upper, Lower and Number for me for Office365 work account. A pain to unlock, but I have work email and calendar.
