ADT Security hub - Red button at startup and reboot

I`ve disconnected my ADT Security hub. It was working fine, but after rebooting (disconected from AC power and battery) it starts with red light in home button and white light in + button. Shows ADT startup screen but stops at the end of the process with “Result 0” message. After a seconds screen become black, buttons remain red and white. Few menutes after system reboots and same cylce starts.

My location is Buenos Aires, Argentina.
Help Please.
