z3 unlock code forgotten

[Klausffm]

Hello, I have forgotten the unlock code for my z3. Not the Sim code! After entering the device, enter the password in the display. I do not know the password anymore. Please help me I've already entered all the passwords that occur to me, also the number * # * # 7378423 # * # * does not work and pressing the keys Power and Loud / silent without function.

unfortunately there is no other way but to reset your device.

try to go to https://myxperia.sonymobile.com/ to see if you can try to unlock your device
