What ist current Firware for HD509N

[Sindbad]

Hello Forum,
I am new in your forum and have some questions:

1) Is the firmware ROM V4.00.11 Build Date June 11, 2014 ZAAPTV HD509N new or is there a newer one?
I had to reset my ZAAPTV HD509N yesterday, because it no longer works! Now it works.

2) I have understood that the HD509N always gets the latest firmware automatically!
Is there any way to download the latest firmware and then to install it via USB?

Thanks in advance
