Hi everyone, my father today tried to update new software on his xperia z. He said he got notif. for update and he approved usually. In the middle of the updating process some mistake has happened and mobile phone has shutted down. Now he can't turn on his phone. After I tried to turn on the phone Sony Xperia screen appear for few seconds after that andorid sign lying with opened stomach and above his stomach triangle with Exclamation mark and after 10sec xperia shutted down. How can I fix it?
