Can anyone help me?
I've tried to repair the phone using the companion app but the "Your device is locked" always shown.
Is there any way to skip pass this?
Hi @Linegod, sorry to hear about your device. 
You can start the repair when the device is turned off and not connected to your computer, so start with turning it off the device. If it doesn't work when using the power button, you can follow the instructions below.
When the device is turned off, make sure that it's not connected to your computer and open up Xperia Companion > click on "Software repair" > check the little box in the bottom left corner > Next and follow the on screen instructions.
Let me know if that helps!
