Operating System does not Lauch

[Romina]

Hello
Recently I discovered a problem with my phone.
I ran out of battery and i didn't have a charger with me. When I got home, I plugged it in and a black screen showed up with the message "Your device is corrupt. It can't be trusted and may not work properly. Visit this link on another device: g.co/ABH; Press power key to continue"
The only way to access the phone is through the reboot menu. However, I've tried rebooting and it doesn't solve the error. I was able to get access to the phone and reset it to the factory settings and the problem is still not solved. How should I proceed?
