Hi,

I just bought my z2 and now I got a big terrible trouble with it. My screen is looked. My sim card is opened and their is my pin code correct. After that I have succeeded to make a terrible misstake om looking the screen with the pin code. When I put in the pin code it says it is the wrong pin code. What shall I do?

I have restarted it a several times.

You need to perform a system repair - This will factory reset your phone

Switch off your phone and unplug from Pc (Hold volume up and power for around 10 seconds)
Start PC Companion and select Support zone then Update my phone/tablet then in Blue Repair my phone/tablet and follow the onscreen instructions - When prompted connect your phone still switched off holding volume down or back button - This should start the repair or reformat process

If you are using Windows 8/8.1 or a 64bit operating system then adjust the settings for PC Companion and run in compatibility mode and chose Windows 7 or XP
