Hi @AETU, let me see if I can help out here.

I have translated your question to English as this is an International forum, please post any replies in English and it will be easier for me and other users to assist you.

From your description it sounds like the anti-theft protection has been activated in the device, known as Google Device Protection. This due to the fact that the phone had an active screen lock before being reset to factory settings. 

To bypass this protection you have to login using the same Google account which you used to activate the service in your device. There is no other way around this due to security reasons. If you do not remember your Google password you may reset it using the  link below

If you still are unable to login I can only advice you to have your device sent in to an authorized service center in order to have it unlocked. In that case, I would suggest that you get in contact with your local support team for further instructions.

I hope that helped! Let me know if I have misinterpreted your question in any way!
