Passcode forgotten on Z3 Compact

[marty80]

Can someone let me know if its possible to unlock or factory-reset a Z3 Compact with the lock screen password forgotten?
There does not seem to be the option to unlock with a Google Account, and I cannot find a way to reset the phone.

In this case you are going to need to run a firmware repair to remove the lock:

@edvin27 You can follow this guide:

/t5/FAQ/How-to-unlock-a-phone-w-o-reseting-reformating-the-phone/m-p/927295#U927295

If you cannot do it, you need to perform a software repair using PC Companion.The process will erase all internal memory.You might need to charge your device for about 1-2 hours before so the device has at least 80% battery.

Make sure the device is not connected to computer or laptop and turned off (sometimes you have to press power button and volume up until the device vibrates 3 times or on some devices you have to press the small button near the SIM tray or on the back of the device).

Open PC companion->support zone->phone/tablet software update->repair my phone/tablet blue highlighted.Follow the steps given,do not connect your phone until prompted to press volume down while plugging USB cable. If PC companion does not start the repair process, you might need to run it in compatibility mode with Windows 7 (in some cases XP).
