LG D410 boot loop after first upgrade topic

Hi. I just turned on my new D410, set up the account and waited until all the apps from my account was installed. Then I let the system to perform a firmware update. After updating and restart, the phone keeps running the bootloop. I even see a home screen/screen locker for a moment, but then the phone reboots. What should I have to do? I wanted to make the hard reset, but I am not able to enter that hard reset menu. (volume down+power, release power for 1 sec while pressing vol down, press power again). After pressing power the second time, phone just starts.
