No keyboard showing up

Hello, i made a factory reset to my phone and now before the screen to chose the device language avast anti-theft request the PIN to unblock the phone. The problem is that when i tap the field to introduce the pin no keyboard shows up, i just get a blinking cursor in the form field. Anyone knows how i can solve this problem?

Any more information about the device, OS or version? Is possible to use shortcuts (copy and paste with long tap)?

HUAWEI y201 pro
Android 4.0.3
long tap seems to work but no option to copy or paste show up
