I am having real problems unlocking my Z30.
At first I thought i was putting in the wrong password. I went through my 5th attempt and spelled out "blackberry". I stopped on my 8th attempt. I picked it up "wrong" and that was my 9th attempt. I am now getting the warning that on "the data on your device will be erased on the next failed attempt". I have had this Z30 for years, you can imagine the number of contacts and passwords in my keeper. Additional info: screen is cracked, but have been able to use it.
